Abstract

Background: Child sexual abuse is considered a modifiable risk factor for mental disorders across the life course. However the long-term consequences of other forms of child maltreatment have not yet been systematically examined. The aim of this study was to summarise the evidence relating to the possible relationship between child physical abuse, emotional abuse, and neglect, and subsequent mental and physical health outcomes.

Methods and Findings: A systematic review was conducted using the Medline, EMBASE, and PsycINFO electronic databases up to 26 June 2012. Published cohort, cross-sectional, and case-control studies that examined non-sexual child maltreatment as a risk factor for loss of health were included. All meta-analyses were based on quality-effects models. Out of 285 articles assessed for eligibility, 124 studies satisfied the pre-determined inclusion criteria for meta-analysis. Statistically significant associations were observed between physical abuse, emotional abuse, and neglect and depressive disorders (physical abuse [odds ratio (OR) = 1.54; 95% CI 1.16–2.04], emotional abuse [OR = 3.06; 95% CI 2.43–3.85], and neglect [OR = 2.11; 95% CI 1.61–2.77]); drug use (physical abuse [OR = 1.92; 95% CI 1.67–2.20], emotional abuse [OR = 1.41; 95% CI 1.11–1.79], and neglect [OR = 1.36; 95% CI 1.21–1.54]); suicide attempts (physical abuse [OR = 3.40; 95% CI 2.17–5.32], emotional abuse [OR = 3.37; 95% CI 2.44–4.67], and neglect [OR = 1.95; 95% CI 1.13–3.37]); and sexually transmitted infections and risky sexual behaviour (physical abuse [OR = 1.78; 95% CI 1.50–2.10], emotional abuse [OR = 1.75; 95% CI 1.49– 2.04], and neglect [OR = 1.57; 95% CI 1.39–1.78]). Evidence for causality was assessed using Bradford Hill criteria. While suggestive evidence exists for a relationship between maltreatment and chronic diseases and lifestyle risk factors, more research is required to confirm these relationships.

Conclusions: This overview of the evidence suggests a causal relationship between non-sexual child maltreatment and a range of mental disorders, drug use, suicide attempts, sexually transmitted infections, and risky sexual behaviour. All forms of child maltreatment should be considered important risks to health with a sizeable impact on major contributors to the burden of disease in all parts of the world. The awareness of the serious long-term consequences of child maltreatment should encourage better identification of those at risk and the development of effective interventions to protect children from violence.

Introduction

Child maltreatment is defined as all forms of physical and/or

emotional ill-treatment, sexual abuse, neglect or negligent treat-

ment, or commercial or other exploitation of children that results in

actual or potential harm to a child’s health, survival, development,

or dignity in the context of a relationship of responsibility, trust, or

power [1]. Four types of maltreatment are commonly recognised:

sexual abuse, physical abuse, emotional abuse (also referred to as

psychological abuse), and neglect (Table 1).

There is a great deal of uncertainty around estimates of the

frequency and severity of child maltreatment worldwide.

Furthermore, much violence against children remains largely

hidden and unreported because of fear and stigma and the

societal acceptance of this type of violence [2]. Globally,

prevalence of reported child sexual abuse varies from 2% to

62%, with some of this variation explained by a number of

methodological factors including definition of abuse, method of

data collection, and type of sample assessed [3]. In high-income

countries, the annual prevalence of physical abuse ranges from

4% to 16%, and approximately 10% of children are neglected

or emotionally abused [4]. Eighty percent of this maltreatment

is perpetrated by parents or parental guardians [4], and poverty,

mental health problems, low educational achievement, alcohol

and drug misuse, having been maltreated oneself as a child, and

family breakdown or violence between other family members

are all important risk factors for parents abusing their children

[5].

There is growing recognition that different forms of interper-

sonal violence have a large public health impact [6]. In children,

the consequences of violence can vary widely. Physical injuries

and, in extreme cases, death are direct consequences. World

Health Organization (WHO) estimates of child homicide suggest

that infants and very young children are at greatest risk, with rates

for the 0- to 4-y age group about double those for 5- to 14-y-olds as

a result of their dependency and vulnerability [5]. However, in the

majority of non-fatal cases, the direct physical injury causes less

morbidity to the child than the long-term impact of the violence

on the child’s neurological, cognitive, and emotional development

and overall health [5].

Child maltreatment is a major public health problem, yet a lack

of understanding of its serious lifelong consequences and of the

cost and burden on society has hampered investment in

prevention policies and programs. In order to effectively respond

to the problem, the WHO 2006 report on prevention of child

maltreatment [5] recommended expanding the scientific evidence

base for the magnitude, consequences, and preventability of child

maltreatment.

The relationship between child sexual abuse and adverse

psychological consequences in adults is well established [7–9],

and in the WHO comparative risk assessment study, Andrews and

colleagues [3] carried out a systematic review and meta-analysis

summarising the evidence of a relationship between child sexual

abuse and subsequent mental disorders. This review is currently

being updated in the new iteration of the Global Burden of

Diseases, Injuries, and Risk Factors Study, aiming to provide

global estimates of attributable burden for 1990 to 2010 [10], but

other forms of child maltreatment have been omitted.

Exposure to non-sexual child maltreatment, namely, physical

abuse, emotional abuse, and neglect, is associated with increased

risk of a wide range of psychological and behavioural problems,

including depression, alcohol abuse, anxiety, and suicidal behav-

iour, and with increased risk of HIV and herpes simplex virus type

2 (HSV2) infection [11–14]. However, the long-term health

consequences of these other forms of child maltreatment have not

been systematically examined. To address these omissions, clarify

the present state of empirical research, and enable the quantifi-

cation of the health impacts of child neglect, physical abuse, and

emotional abuse at the population level using burden of disease

and comparative risk assessment methodology, we conducted a

systematic review of the scientific literature and quantitative meta-

analyses. To the best of our knowledge, this is the first meta-

analysis to summarise the evidence for associations between

individual types of non-sexual child maltreatment and outcomes

related to mental and physical health.

Methods

General recommendations from the PRISMA 2009 revision

[15], with regard to processing and reporting of results, were taken

Table 1. Definition of child maltreatment.

Type of Maltreatment Description

Physical abuse Physical abuse of a child is defined as the intentional use of physical force against a child that results in—or has a high likelihood of resulting in—harm for the child’s health, survival, development, or dignity. This includes hitting, beating, kicking, shaking, biting, strangling, scalding, burning, poisoning, and suffocating. Much physical violence against children in the home is inflicted with the object of punishing.

Sexual abuse Sexual abuse is defined as the involvement of a child in sexual activity that he or she does not fully comprehend, is unable to give informed consent to, or for which the child is not developmentally prepared, or else that violates the laws or social taboos of society. Children can be sexually abused by both adults and other children who are—by virtue of their age or stage of development—in a position of responsibility, trust, or power over the victim.

Emotional and psychological abuse Emotional and psychological abuse involves both isolated incidents, as well as a pattern of failure over time on the part of a parent or caregiver to provide a developmentally appropriate and supportive environment. Acts in this category may have a high probability of damaging the child’s physical or mental health, or his/her physical, mental, spiritual, moral, or social development. Abuse of this type includes the following: the restriction of movement; patterns of belittling, blaming, threatening, frightening, discriminating against, or ridiculing; and other non-physical forms of rejection or hostile treatment.

Neglect Neglect includes both isolated incidents, as well as a pattern of failure over time on the part of a parent or other family member to provide for the development and well-being of the child—where the parent is in a position to do so—in one or more of the following areas: health, education, emotional development, nutrition, shelter, and safe living conditions. The parents of neglected children are not necessarily poor.

into account (Text S1). The meta-analysis conforms to the

guidelines outlined by the Meta-analysis of Observational Studies

in Epidemiology recommendations [16]. Methods and inclusion

criteria were specified in advance and documented in a review

protocol (Text S2).

Inclusion and Exclusion Criteria This systematic review and meta-analysis incorporated retro-

spective and prospective cohort, cross-sectional, and case-control

studies meeting the following inclusion criteria: (1) the study

reported original, empirical research published in a peer-reviewed

journal, (2) the study considered non-sexual child maltreatment as

a potential risk factor for loss of health, and (3) the related health

outcomes or behavioural risk factors were among those listed in

the Global Burden of Diseases, Injuries, and Risk Factors Study

[10]. Studies reporting exposure only to combined types of abuse

were excluded. Included studies reported odds ratios (ORs) and

confidence intervals (CIs) comparing those exposed and not

exposed by type of abuse or, alternatively, provided the

information from which effect sizes and confidence intervals could

be calculated (Text S2).

Search Strategy Three electronic databases (Medline, EMBASE, and PsycINFO

up to 26 June 2012) were searched using full text and Medical

Subject Headings (MeSH) terms to identify studies reporting an

association between non-sexual child maltreatment and health

outcomes (Text S2). Truncation of terms was used to capture

variation in terminology. The search was not restricted to the

English language, nor restricted by any other means. Searches

were conducted using synonyms and combinations of the following

search terms: ‘‘maltreatment’’, ‘‘physical abuse’’, ‘‘psychological

abuse’’, and ‘‘emotional abuse’’, and automatic explosion of the

terms ‘‘child abuse’’ and ‘‘child neglect’’. The search was also not

restricted to any particular health outcome. Instead, the broader

terms ‘‘risk’’, ‘‘adverse effect’’, ‘‘consequences’’, ‘‘harm’’, and ‘‘as-

sociation’’ were used to encompass all studies that investigated any

adverse outcome of non-sexual child maltreatment. In addition,

reference lists of selected studies were screened for any other

relevant study, and additional studies were also identified through

contact with study authors. Articles in languages other than

English were translated.

Data Collection and Quality Assessment The full-text article of any study that appeared to meet the

inclusion criteria was retrieved for closer examination. Two

reviewers (R. E. N. and M. B.) independently assessed articles for

eligibility. Disagreements were resolved by consensus. The coders

were not masked to the journals or authors of the studies reviewed. A

standardised data extraction sheet was developed, and data retrieved

included publication details, country where study was conducted,

methodological characteristics such as sample size and study design,

exposure and outcome measures, type of abuse, and health outcomes

(Text S2). The data extraction sheet included a quality assessment

tool (Table 2) to rate the methodological quality of each study based

on the Newcastle-Ottawa Scale for assessing the quality of

observational studies [17]. Quality assessment was completed

independently by two reviewers, and disagreements were resolved

by discussion. One author was contacted for further information.

Statistical Analyses Weighted summary measures were computed using MetaXL,

version 1.2 [18], a tool for meta-analysis in Microsoft Excel, with

ORs chosen as the principal summary measure. Heterogeneity

was quantitatively assessed using the Cochran’s Q and I 2

statistics

to evaluate whether the pooled studies represent a homogeneous

distribution of effect sizes. Evidence of publication bias was

investigated by means of funnel plots using the standard error on

the y-axis [19].

Meta-analyses were complicated by the presence of significant

heterogeneity in the data, likely due to a combination of true

variance in these relationships and variability produced by

differences in the methodology used to measure exposure and

outcomes. We hypothesised that effect size may differ according to

the methodological quality of the studies. MetaXL implements a

process to explicitly address study heterogeneity caused by

differences in study quality. This so-called quality effects (Doi

and Thalib) model [20] is a modified version of the fixed-effects

inverse variance method that additionally allows giving greater

weight to studies of high quality versus studies of lesser quality by

using the quality scores assigned to each study to weigh studies not

only according to sample size but also by study quality [20,21].

Forest plots were made to visualise individual as well as pooled

effects.

To address the effects of important study characteristics and

explore heterogeneity, we additionally conducted several pre-

specified subgroup analyses (depending on data availability) by the

following: gender of participants in the sample, geographic

location (high income versus low-to-middle income), type of

sample (population-based versus non-representative samples),

measurement of abuse (self-reported versus official records),

assessment of health outcome (structured clinical interview versus

self-reported), prospective versus retrospective assessment of abuse

and neglect, and appropriate adjustment versus no or inadequate

adjustment for confounders.

Results

Out of 285 articles assessed for eligibility, 124 studies provided

evidence of a relationship between non-sexual child maltreatment

and various health outcomes for use in subsequent meta-analyses

(Figure 1). The majority (n = 112) were from Western Europe,

North America, Australia, and New Zealand. Data from low- and

middle-income countries were sparse. Only 16 studies used a

prospective cohort design that followed abused or neglected

children over time to identify later health outcomes (Table 3). The

remaining studies included cohort, cross-sectional, and case-

control studies that measured the maltreatment retrospectively,

usually by self-report in adolescence or adulthood. Most of the

studies included in our meta-analysis presented data from regional

or nationally representative samples (Table 3). The results of

primary meta-analyses are presented in Tables 4–6, with Figures

S1, S2, S3, S4, S5, S6, S7, S8, S9, S10, S11, S12, S13, S14, S15,

S16, S17, S18, S19, S20, S21, S22, S23, S24, S25, S26, S27, S28,

S29, S30, S31, S32, S33, S34, S35, S36, S37, S38, S39, S40, S41,

S42 showing the forest plots of these meta-analyses. Details of

subgroup analyses are presented in Tables S1, S2, S3, S4, S5, S6,

S7, S8, S9, S10, S11.

Mental Disorders Physically abused (OR = 1.54; 95% CI 1.16–2.04), emotionally

abused (OR = 3.06; 95% CI 2.43–3.85), and neglected (OR = 2.11;

95% CI 1.61–2.77) individuals were found to have a higher risk of

developing depressive disorders than non-abused individuals

(Table 4; Figures S1, S2, S3). The test for heterogeneity was highly

significant, with p,0.01 for both abuse types and neglect. Funnel

plots indicate the possibility of publication bias for physical abuse, as

it appears that some smaller, less precise studies have a greater effect

size than the larger studies, and there are no smaller studies to the

left (negative) side of the graph, suggesting that some negative

studies may never have been published (Figure S4).

For physical abuse, emotional abuse, and neglect, OR estimates

in males were higher than in females, but the difference was not

statistically significant (Table S1). The odds of developing

depressive disorders with exposure to physical abuse were greatest

in prospective studies. Although the OR point estimate was higher

in subgroup analyses of studies where exposure to physical abuse

was court-substantiated by official records—which would include

the more severe cases of abuse (OR = 2.41; 95% CI 1.32–4.41)—

compared with self-reported physical abuse (OR = 1.56; 95% CI

1.11–2.19) and physical punishment (OR = 1.20; 95% CI 0.88–

1.61), the 95% CIs were overlapping, and these differences were

not statistically significant. There was a stronger association

between physical abuse and a diagnosis of major depressive

disorder using structured interviews (OR = 1.82; 95% CI 1.44–

2.30) than when depressive disorders were diagnosed by symptom

scales (OR = 1.52; 95% CI 1.03–2.24), but again these differences

were not statistically significant (Table S1). Restricting the physical

abuse analysis to studies from high-income countries increased the

odds of developing depressive disorders to 1.58 (95% CI 1.18–

2.12), but the association was not significant in low-to-middle-

income countries (Table S1).

However, for neglect in childhood, similar odds of developing

depressive disorders were observed in high- and low-to-middle-

income countries. Data from two studies suggest a dose–response

relationship, with depression more likely with frequent neglect

compared with neglect that occurred only sometimes in childhood

[13,22]. A dose–response relationship was also reported for

emotional abuse and depressive disorders, but not for physical

abuse and depressive disorders (Table S1).

Physical abuse (OR = 1.51; 95% CI 1.27–1.79), emotional

abuse (OR = 3.21; 95% CI 2.05–5.03), and neglect (OR = 1.82;

95% CI 1.51–2.20) were associated with a significantly increased

risk of anxiety disorders (Figures S5, S6, S7, S8). For physical

abuse, significant associations were also observed with post-

traumatic stress disorder (PTSD) and panic disorder diagnoses

(Table S2). A dose–response relationship was observed with

physical abuse but not with emotional abuse and neglect [22],

with anxiety disorders more likely with frequent physical abuse

than with abuse that occurred only sometimes in childhood

(Table S2). Physical abuse, emotional abuse, and neglect were

also associated with an almost 3-fold increased risk of developing

eating disorders (Figures S9, S10, S11, S12), and physical abuse

was associated with a 5-fold increased risk of developing bulimia

nervosa meeting Diagnostic and Statistical Manual of Mental

Disorders (DSM) diagnostic criteria. Most of the evidence came

from retrospective studies, and only one prospective study [23]

reported a strong association with neglect in childhood (Table

S3). A dose–response relationship was also observed, with bulimia

nervosa more likely with more severe and repeated physical abuse

[24] (Table S3).

Physical abuse and neglect were also associated with a

doubling of the odds of childhood behavioural and conduct

disorders (Figures S13, S14, S15). With respect to physical

abuse, higher odds of developing conduct and childhood

behavioural disorders were observed in prospective than in

retrospective studies, but differences were not statistically

significant. Studies with non-representative samples had signif-

icantly increased effect size for the association between physical

abuse and childhood behavioural problems and conduct

disorder (OR = 5.98; 95% CI 2.73–13.10) compared with

Consequences of Child Nonsexual Maltreatment

PLOS Medicine | www.plosmedicine.org 15 November 2012 | Volume 9 | Issue 11 | e1001349

population-based studies (OR = 2.02; 95% CI 1.58–2.58) (Table

S4).

Physical abuse significantly increased the risk of alcohol

problem drinking (risky drinking, alcohol abuse/dependence,

binge drinking) (OR = 1.26; 95% CI 1.03–1.55) (Figure S16) and

non-problem drinking (current or ever alcohol use), but the effect

did not persist in prospective studies (Table S5). In a subgroup

analysis, physical abuse was also significantly associated with a

diagnosis of alcohol abuse/dependence meeting DSM criteria

(OR = 1.40; 95% CI 1.21–1.64) (Table S5). Alcohol problem

drinking was also associated with emotional abuse (OR = 1.27;

95% CI 1.11–1.46) (Figure S17) but not with neglect in childhood

(OR = 1.09; 95% CI 0.87–1.35) (Figure S18). For alcohol

problems, there was no evidence of a dose–response relationship

with respect to frequency of abuse and neglect (Table S5) [13].

Gender differences were observed, with the effect of physical abuse

on alcohol problems stronger among males, and with females at an

increased risk of alcohol problem drinking with exposure to

neglect in childhood, but with overlapping confidence intervals

(Table S5). Publication bias did not appear to play a role in the

association between physical abuse and alcohol problem drinking

(Figure S19).

Although primary analyses suggest an increased risk of drug use

associated with physical abuse (OR = 1.92; 95% CI 1.67–2.20),

emotional abuse (OR = 1.41; 95% CI 1.11–1.79), and neglect

(OR = 1.36; 95% CI 1.21–1.54) (Figures S20, S21, S22, S23),

there was only borderline significance in prospective studies, with a

stronger consistent association observed in retrospective studies,

albeit with overlapping confidence intervals (Table S6). A dose–

response relationship between emotional abuse and neglect and

drug use was not consistently seen.

Physically abused (OR = 3.00; 95% CI 2.07–4.33), emotionally

abused (OR = 3.08; 95% CI 2.42–3.93), and neglected

(OR = 1.85; 95% CI 1.25–2.73) individuals had a significantly

increased risk of suicidal behaviour compared with non-abused

individuals (Table 4). These significant associations continued in

subgroup analyses by type of suicidal behaviour, with physically

abused (OR = 3.40; 95% CI 2.17–5.32), emotionally abused

(OR = 3.37; 95% CI 2.44–4.67), and neglected (OR = 1.95; 95%

CI 1.13–3.37) individuals at a significantly increased risk of suicide

attempt (Figures S24, S25, S26, S27) and suicide ideation (Table

S7). There were no prospective studies investigating non-sexual

child maltreatment and suicide attempt or ideation. Only one

prospective study [25] was found investigating the association

between self-inflicted injuries and exposure to physical abuse and

neglect. Six studies [13,26–30] presented the results by gender for

physical abuse and suicide attempt and ideation, but no

statistically significant differences were observed. One study

showed that exposure to frequent childhood neglect was more

strongly associated with suicidal behaviour than exposure to

neglect that occurred sometimes [13] (Table S7).

Sexually Transmitted Infections and Risky Sexual Behaviour

Physically abused (OR = 1.78; 95% CI 1.50–2.10), emotionally

abused (OR = 1.75; 95% CI 1.49–2.04), and neglected

(OR = 1.57; 95% CI 1.39–1.78) individuals were found to have

a significantly higher risk of sexually transmitted infections (STIs)

and/or risky sexual behaviour than non-abused individuals

(Table 5; Figures S28, S29, S30, S31). For physical abuse and

neglect, the association with STIs and risky sexual behaviour was

significant in prospective and retrospective studies (Table S8). HIV

infection was about twice as common in physically abused

(OR = 2.51; 95% CI 1.16–5.42), emotionally abused (OR = 1.82;

individuals as in controls, although for neglect the difference did

not reach conventional levels of significance, probably because of

weak statistical power. Physical abuse was also associated with an

increased risk of other STIs (OR = 1.53; 95% CI 1.13–2.07) and

risky sexual behaviour (OR = 1.95; 95% CI 1.58–2.40) (Table 5).

A dose–response relationship was observed for HIV infection, with

a larger effect size reported with more frequent physical and

emotional abuse in childhood [13] (Table S8).

Chronic Diseases, Lifestyle Risk Factors, and Other Physical Health Outcomes

With regard to obesity, a significantly increased risk was

observed for physical (OR = 1.32; 95% CI 1.06–1.64) and

emotional abuse (OR = 1.24; 95% CI 1.13–1.36) but not for

neglect (OR = 1.07; 95% CI 0.97–1.19) in the primary analysis

(Figures S32, S33, S34, S35). Subgroup analysis by assessment of

outcome indicated that neglect was associated with a higher risk of

developing self-reported obesity, but there was no association with

obesity defined by waist circumference or body mass index (BMI)

measurements (Table S9). In the subgroup analysis by ascertain-

ment of exposure to physical abuse, there was a strong association

with obesity in one prospective study, but the magnitude of the

effect was reduced in retrospective studies (Table S9). A dose–

response relationship between physical and emotional abuse and

obesity has been observed [31] (Table S9).

Physical (OR = 1.78; 95% CI 1.26–2.52) (Figure S36) and

emotional abuse (OR = 1.65; 95% CI 1.46–1.87) (Figure S37)

were associated with a significantly increased risk of current

smoking, but the association was not significant for neglect in

childhood (OR = 1.20; 95% CI 0.98–1.48). One study showed a

dose response, with smoking more likely with physical abuse that

occurred 3–5 times than with abuse that occurred 1–2 times, but

this relationship did not continue into those who had been abused

more than six times compared with those who had been abused 3–

5 times [32] (Table S10).

Forty-two studies investigated the relationship between non-

sexual child maltreatment and lifestyle risk factors, chronic

diseases, and other physical health outcomes in adulthood. There

is suggestive evidence of a significant association between child

physical abuse and arthritis, ulcers, and headache/migraine in

adulthood. However, for most other outcomes, including type 2

diabetes (Table S11; Figures S39, S40, S41, S42), hypertension,

low exercise, cardiovascular diseases, respiratory diseases, neuro-

logical disorders, and cancer, these associations were mostly weak

and inconsistent, with little adjustment for lifetime confounders.

Pooled estimates were statistically significant in only a limited

number of cases (Table 6). A recent prospective investigation of a

group of individuals with documented histories of child abuse and

neglect followed into middle adulthood provides some evidence

that child abuse and neglect may increase the risk of a range of

directly measured physical health outcomes after controlling for

mental health problems, substance use, smoking, and BMI [33]

(Table 7). However, there were insufficient studies examining the

association between non-sexual child maltreatment and some of

these health outcomes, including anaemia, underweight/malnu-

trition, hepatitis C, tuberculosis, hearing loss, vision loss, oral

health, diarrhoea, allergies, uterine leiomyoma, back pain, breast

cancer, and schizophrenia, to undergo meta-analysis (Table 7).

Discussion

To the best of our knowledge, this article presents the first

systematic review and meta-analysis of published studies assessing

the association between non-sexual child maltreatment and mental

and physical health outcomes. We identified 124 studies that

examined the association between physical abuse, emotional

abuse, and neglect in childhood and various health outcomes.

Does Non-Sexual Child Maltreatment Cause Adverse Health Outcomes?

Evidence for a causal relationship between non-sexual child

maltreatment and health outcomes was evaluated within the

Bradford Hill framework on the grounds of the following

important criteria: strength and consistency of the association,

the temporal relationship of the association, evidence of a

biological gradient or dose–response relationship, biological

plausibility, and consideration of alternate explanations [34]

(Table S12).

Temporality Both prospective and retrospective studies consistently showed

an association between exposure to child physical abuse,

emotional abuse, and neglect and adverse health outcomes. The

availability of prospective studies provides conclusive evidence of a

temporal relationship between exposure to non-sexual child

maltreatment and the later development of mental health

outcomes, drug use, and STIs and risky sexual behaviour, as in

these studies abuse and neglect preceded the onset of health

problems in adulthood.

However, only 16 studies were prospective, while the majority

of the studies were cross-sectional and relied on adult retrospective

report of abuse and neglect in childhood. By definition, these

studies cannot prove a temporal relationship between exposure to

child maltreatment and the onset of health outcomes. Further-

more, retrospective, self-reported information regarding abuse in

childhood may be subject to recall bias, where those with

adjustment problems may be more prone to recall or disclose

exposure to abuse and neglect. In many cases participants were

asked to report on events that would have occurred many years

before, and the issue of potentially unreliable recall threatens the

validity of the published literature on child maltreatment. At least

with respect to child sexual abuse, evidence suggests moderate to

good consistency of reports over time [35]. It has also been

suggested that biases are probably towards under-reporting rather

than over-reporting of abuse [36]. Nevertheless, given that

retrospective reports were often the only measure of abuse

available, particularly with regard to emotional abuse, we accepted

these within the context of the limitations stated.

Although the strength of prospective studies includes the

temporal ordering of maltreatment and subsequent health

outcomes, with an objective measurement of exposure to abuse,

these studies are usually conducted in non-representative samples.

Official cases of abuse may only detect those who come to

professional attention, and this may alter the strength of the

association between non-sexual child maltreatment and adult

morbidity. These official cases are also generally skewed towards

the lower end of the socioeconomic spectrum and may not be

generalisable to child abuse and neglect cases that occur in middle-

or upper-class children [33]. Those participants who have been

identified by child protection agencies as having been exposed to

physical abuse or neglect may have received interventions to

prevent later pathology. Furthermore, some individuals in the

‘‘never maltreated’’ category may actually have experienced

maltreatment, given that child maltreatment tends to be under-

reported. The validity of the various study designs to investigate

the long-term health consequences of child maltreatment has been

a source of ongoing debate [37,38]. In this meta-analysis we have

included prospective and retrospective studies. The subgroup

analyses show that with both methodologies there is robust

evidence of a significant association between child non-sexual

maltreatment and various health outcomes.

Strength of the Association Associations between child physical abuse, emotional abuse, and

neglect and mental disorders, drug use, and suicidal behaviour

have been reported in prospective studies and/or large popula-

tion-based studies. The strength of the relationship between abuse

and mental disorders was generally reduced when the effects of

important mediating variables were taken into account. Despite

some variability, overall, child physical abuse, emotional abuse,

and neglect were found to approximately double the likelihood of

adverse mental health outcomes when combined in a meta-

analysis.

Consistency of the Association As shown in the forest plots of the effects by study, there was

strong consistency and agreement in the estimated effect measures

across studies, particularly for neglect and physical abuse, although

we suspect publication bias for some of the outcomes. Risk

estimates were comparable across different types of samples, for

both non-representative and representative populations (Tables

S1, S2, S3, S4 and S6, S7, S8). The findings persisted across

different study designs, samples, and geographic regions investi-

gated. It can be concluded that there is a highly consistent

association between child physical abuse, emotional abuse, and

neglect and adverse mental health outcomes, drug use, and STIs

and risky sexual behaviour. We did not observe evidence of strong

consistent associations for alcohol problems, chronic diseases, or

lifestyle risk factors.

Dose–Response Relationship We found evidence of a dose–response relationship between

adverse health outcomes and non-sexual child maltreatment, such

that those experiencing more severe abuse or neglect were at

greater risk of developing mental disorders than those experienc-

ing less severe maltreatment [39]. In the Chapman et al. [40]

study, increasing severity of childhood adversity corresponded

with poorer mental health outcomes. Consistent dose–response

relationships with repeated, frequent, or severe abuse have been

reported for mental disorders and physical abuse [13,24,41] and

emotional abuse and neglect [13,22]. Furthermore, there is

evidence to suggest that experiencing multiple types of maltreat-

ment may carry more severe consequences, with those exposed to

multiple types of abuse at increased odds of developing mental

disorders [42,43], and the risk increases with the magnitude of

multiple abuse [44]. Dose–response relationships with repeated

frequent or severe abuse have also been reported for STIs and

physical and emotional abuse [13], obesity and emotional and

physical abuse [31], and smoking and physical abuse [32].

Plausibility With respect to biological plausibility, animal models of mental

disorders do not exist, making it particularly difficult to understand

the underlying biological mechanisms. Progress in understanding

has to be made by association and inference rather than

experimental data [3]. There are nevertheless several potential

mechanisms that may explain the observed association between

abuse and neglect in childhood and increased risk of mental health

problems. Neurobiological development can be physiologically

altered by maltreatment during a child’s early years, which can in

turn negatively affect a child’s physical, cognitive, emotional, and

social growth, leading to psychological, behavioural, and learning

problems that persist throughout the life course [45,46]. More-

over, cumulative trauma may further increase risk [47], and some

victims of abuse may try to manage the subsequent distress

through the use of alcohol, prescription medication, tobacco, or

other drugs.

There is emerging evidence that the origins of most adult

disease are found among developmental and biological disruptions

in childhood. These early life experiences can affect adult mental

and physical health either by cumulative damage over time or by

the biological embedding of adversities during sensitive develop-

mental periods [48]. There is generally a lag of many years before

early adverse experiences are expressed in the form of disease [48].

Consequences of Child Nonsexual Maltreatment

Andrews and colleagues concluded that despite the lack of a

biological link between child sexual abuse and mental disorders, a

causal relationship was plausible [3], and that child maltreatment

is most likely a contributory cause that acts via other intermedi-

ates.

Consideration of Alternate Explanations It is important to note that the role of genes, environment, and

gene–environment interactions in the causation of mental

disorders is not well understood. Twin studies provide one of the

best ways to examine the interplay between genetic and

environmental influences [3], but to the best of our knowledge,

these are only available for child sexual abuse. The relationship

between abuse and neglect in childhood and subsequent health

effects is complex. Although childhood abuse and neglect does

result in adverse health outcomes, these outcomes are not

independent of broader socioeconomic contexts. Lifestyle factors,

access to health care, and neighbourhood characteristics may act

as mediators between child abuse and neglect and long-term

health consequences [49–51]. Exposure to child maltreatment

often co-occurs within the context of other family dysfunction,

social deprivation, and other environmental stressors that are also

associated with mental disorders. Child maltreatment may be a

marker of other family problems that together lead to the

development of mental disorders. In addition, findings from many

studies do not take into account the likely contribution of

hereditary influences on the predisposition to mental disorders.

Children of depressed parents may be at greater risk of depression

through both exposure to maltreatment by their parents and

genetic predisposition [43]. Hence, some of the effect of child

abuse and neglect on mental disorders may still be explained by

confounding. However, the effect of abuse on mental disorders

remained significant in the majority of studies included in these

meta-analyses after controlling for these co-occurring factors.

Assessment of Causality In summary, there was robust evidence of significant associa-

tions between exposure to non-sexual child maltreatment and

increased likelihood of a range of mental disorders, suicide

attempts, drug use, STIs, and risky sexual behaviour. An increase

in the likelihood of alcohol problem use was not consistently seen.

There is weak to limited evidence suggesting a relationship

between non-sexual child maltreatment and certain physical

disorders and risk factors (Table 8), but more research is required

to confirm these relationships.

Study Limitations Although these findings and conclusions seem to be relatively

consistent and robust, they should be interpreted in light of a

number of limitations of our analysis.

This meta-analysis may be subject to publication bias because

non-significant findings are less likely to be published [52]. This

problem is increased when statistical models are employed because

often only significant estimates are reported in many studies. This

may result in the association between child abuse and neglect and

outcomes being overstated, particularly for depressive disorders

and anxiety, where publication bias may have played a role. For

some of the other conditions there were too few studies to make

conclusions with respect to publication bias.

The analysis also suffers from inconsistencies in how child abuse

and neglect are defined and measured across the studies, as shown

in Table 3. In studies using child protection records, exposure to

physical abuse was defined to include injuries such as bruises,

welts, burns, abrasions, lacerations, wounds, cuts, and fractures.

Some studies used the Barnett-Cicchetti Maltreatment Classifica-

tion System [53] which defines physical abuse as a caregiver or

responsible adult inflicting physical injury upon a child by other

than accidental means. In other studies physical abuse was defined

as having been hit, kicked, or punched so hard that the individual

had marks or bruising or needed medical attention. Some studies

referred to physical punishment [13,54,55] and corporal punish-

ment [56], which may exclude more severe physical abuse, as well

as physical assault by caregivers [57]. Emotional abuse definitions

also varied considerably and included verbal abuse and being

humiliated by a caregiver. Most studies involving neglect referred

simply to ‘‘neglect’’, while others distinguished between physical

and emotional neglect. Similarly, definitions of childhood were not

consistent across studies. The complexity of defining and

measuring child abuse has been noted in several studies [58–60].

Measurement bias with respect to health outcomes and the

questionable reliability of self-reported data may also have affected

the results. We dealt with this issue in the meta-analysis by

adjusting the quality score and performing subgroup analyses. For

mental disorders, studies using well-validated and standardised

diagnostic instruments were assigned a higher quality score than

studies using self-report symptom scales.

Another limitation of meta-analyses of observational studies is

that, since individuals cannot be randomly allocated to case

groups, the influence of confounding variables cannot be fully

evaluated. While most studies presented multivariable adjusted

ORs controlling for a range of socio-demographic and study

design variables, a few studies presented unadjusted associations

between child maltreatment and health outcomes, or adjusted for

age and sex only. We again dealt with this issue in our meta-

analysis by adjusting the quality score of studies with inadequate

control for confounding and by carrying out separate analyses

depending on data availability. Some studies also statistically

controlled for exposure to other forms of maltreatment by

including the different types of abuse in the same model in order

to determine the independent contribution of each abuse type.

Generally, in studies presenting results from various unadjusted

and adjusted models, the association between abuse and physical

and mental health outcomes was attenuated when controlling for

the effects of mediating variables [61–72] and other forms of abuse

[73–79]. However, findings from a recent prospective cohort study

indicate that for some physical health outcomes additional control

for socioeconomic status, unhealthy behaviour, smoking, and

mental health problems seems to play varying roles in attenuating

or intensifying these complex relationships [33]. Furthermore, we

cannot exclude that residual confounding or unmeasured potential

confounders may still remain. Despite evidence of weak associa-

tions between non-sexual child maltreatment and chronic diseases,

further studies are needed that ensure adequate adjustment for

lifetime confounders, because the attributable burden would be

appreciable.

Significant heterogeneity exists in the primary analysis of

physical and emotional abuse, even after our attempts to control

for study quality in quality effects models, and the heterogeneity

remained significant in most of the subgroup analyses. Given this

situation, combining the effects may not be justified. With respect

to neglect, pooled estimates in primary and subgroup analyses did

not show significant heterogeneity for many outcomes.

Recommendations Inconsistencies in the measurement and definition of child

maltreatment highlight the importance of international efforts to

standardise studies to enhance the comparability of findings. These

include defining the cutoff age for childhood (0–18 y, as specified

Consequences of Child Nonsexual Maltreatment

PLOS Medicine | www.plosmedicine.org 23 November 2012 | Volume 9 | Issue 11 | e1001349

by the United Nations), and breaking this period into smaller age

bands that can reflect age-specific patterns [5]. Researchers should

select methodologies and instruments with international compar-

isons in mind. Identical questionnaires, research designs, and

interviewing techniques should ideally be used for surveys in

different countries [5]. In reality, however, all survey methods will

require at least some adaptation to local conditions, and efforts to

ensure comparability should involve choosing definitions of abuse

and neglect, and questionnaire items, that represent an advanced

level of knowledge [80]. To minimise how participants’ subjective

perceptions and definitions shape the answers, it is recommended

that self-report studies clearly specify the behaviours and

experiences being investigated, and that each sub-type of abuse

and neglect is explored using multiple behaviourally specific

questions, instead of a single-item ‘‘label question’’ [81].

Examples of international efforts to increase comparability

across studies include the WHO’s establishment of a global

adverse childhood experiences research network, and the Inter-

national Society for Prevention of Child Abuse and Neglect’s

Child Abuse Screening Tools (ICAST). The WHO network has

developed an international version of the Adverse Childhood

Experiences (ACE) questionnaire (the ACE International Ques-

tionnaire), for administration to people aged 18 y and older, which

is currently being validated through trial implementation as part of

broader health surveys in several countries [82]. The ICAST

initiative has involved the development of three instruments that

ask parents about their use of different behaviours for discipline,

young adults (18–24 y) about their exposure to child abuse and

neglect in childhood, and older children about their own recent

experiences of violence [83].

Child maltreatment deserves increased investment in preventive

and treatment strategies. Currently, there is a paucity of evidence-

based interventions to reduce child maltreatment. Further

research is urgently needed to identify programs that reduce the

prevalence of child maltreatment, thereby alleviating an important

risk factor for later health problems. Evidence-based systemic

interventions that improve parenting strategies and family

functioning may be more effective and economical than attempt-

ing to treat the wide-ranging deleterious health outcomes in

adulthood that arise from maltreatment in the early years of life

[48,84].

A broad range of protective factors have been identified that

assist in promoting resilience in children exposed to adversity. Self

control, problem-solving skills, secure relationships with caregivers,

and safe schools and neighbourhoods are known to reduce the risk

of adverse consequences in children exposed to trauma [85,86].

There is mounting evidence that exposure to childhood adversity

interacting with particular genetic dispositions such as the short

allele of the serotonin transporter gene [87] and genes involved in

the regulation of the hypothalamic–pituitary axis [88,89] can

result in problems with stress regulation and increased risk of

anxiety and depression. Epigenetic changes have also been

postulated as a mechanism by which transgenerational resilience

or vulnerability may occur [90]. In spite of the increased

knowledge in this field, it remains a challenge to translate this

research into interventions at a population level that can reduce

the vulnerability of children exposed to maltreatment [91].

Conclusion This overview of the evidence suggests a causal relationship

between non-sexual child maltreatment and a range of mental

disorders, drug use, suicide attempts, sexually transmitted infections,

and risky sexual behaviour. There is also emerging evidence that

neglect in childhood may be as harmful as physical and emotional

abuse. Although these conclusions have been drawn before from

single empirical studies, in this article they are demonstrated in

aggregate quantitative effects, to our knowledge for the first time.

This review contributes to a better understanding and

measurement of the non-injury health impacts of child maltreat-

ment globally and enables quantification of the burden attribut-

able to physical and emotional abuse and neglect at the population

level using comparative risk assessment methodology [92]. All

forms of child maltreatment should be considered as part of the

cluster of interpersonal violence risk factors in future global

comparative risk assessments. Attributable burden is likely to be

substantial, given the high prevalence of these forms of child

maltreatment, the strong associations reported in our analysis, and

the fact that related health outcomes are among the leading causes

of disease burden globally. Despite the magnitude of the problem

and increasing awareness of its high social costs, preventing child

maltreatment is not a political priority in most countries. It is

imperative that epidemiology and public health approaches find

their proper place at the forefront of national and international

efforts to understand and prevent child maltreatment [93].

Consequences of Child Nonsexual Maltreatment

Editors’ Summary

Background. Child maltreatment—the abuse and neglect of children—is a global problem. There are four types of child maltreatment—sexual abuse (the involvement of a child in sexual activity that he or she does not understand, is unable to give consent to, or is not developmentally prepared for), physical abuse (the use of physical force that harms the child’s health, survival, development, or dignity), emotional abuse (the failure to provide a supportive environment by, for example, verbally threatening the child), and neglect (the failure to provide for all aspects of the child’s well-being). Most child maltreatment is perpetrated by parents or parental guardians, many of whom were maltreated themselves as children. Other risk factors for parents abusing their children include poverty, mental health problems, and alcohol and drug misuse. Although there is considerable uncertainty about the frequency and severity of child maltreatment, according to the World Health Organi- zation (WHO) about 20% of women and 5%–10% of men report being sexually abused as children, and the prevalence of physical abuse in childhood may be 25%–50%.

Why Was This Study Done? Child maltreatment has a large public health impact. Sometimes this impact is immediate and direct (injuries and deaths), but, more often, it is long-term, affecting emotional development and overall health. For child sexual abuse, the relationship between abuse and mental disorders in adult life is well-established. Exposure to other forms of child maltreatment has also been associated with a wide range of psychological and behav- ioral problems, but the health consequences of physical abuse, emotional abuse, and neglect have not been systematically examined. A better understanding of the long-term health effects of child maltreatment is needed to inform maltreatment prevention strategies and to improve treatment for children who have been abused or neglected. In this systematic review and meta-analysis, the researchers quantify the association between exposure to physical abuse, emotional abuse, and neglect in childhood and mental health and physical health outcomes in later life. A systematic review uses predefined criteria to identify all the research on a given topic; a meta-analysis is a statistical approach that combines the results of several studies.

What Did the Researchers Do and Find? The researchers identified 124 studies that investigated the relationship between child physical abuse, emotional abuse, or neglect and various health outcomes. Their meta-analysis of data from these studies provides suggestive evidence that child physical abuse, emotional abuse, and neglect are causally linked to mental and physical health outcomes. For example, emotionally abused individuals had a three-fold higher risk of developing a depressive disorder than non-abused individuals (an odds ratio [OR] of 3.06). Physically abused and neglected individuals also had a higher risk of developing a depressive disorder than non-abused individ- uals (ORs of 1.54 and 2.11, respectively). Other mental health disorders associated with child physical abuse, emotional abuse, or neglect included anxiety disorders, drug abuse,

and suicidal behavior. Individuals who had been non- sexually maltreated as children also had a higher risk of sexually transmitted diseases and/or risky sexual behavior than non-maltreated individuals. Finally, there was weak and inconsistent evidence that child maltreatment increased the risk of chronic diseases and lifestyle risk factors such as smoking.

What Do These Findings Mean? By providing sugges- tive evidence of a causal link between non-sexual child maltreatment and mental health disorders, drug use, suicide attempts, and sexually transmitted diseases and risky sexual behavior, these findings contribute to our understanding of the non-injury health impacts of child maltreatment. Although most of the studies included in the meta-analysis were undertaken in high-income coun- tries, the findings suggest that this link occurs in both high- and low-to-middle-income countries. They also suggest that neglect may be as harmful as physical and emotional abuse. However, they need to be interpreted carefully because of the limitations of this meta-analysis, which include the possibility that children who have been abused may share other, unrecognized factors that are actually the cause of their later mental health problems. Importantly, this confirmation that physical abuse, emo- tional abuse, and neglect in childhood are important risk factors for a range of health problems draws attention to the need to develop evidence-based strategies for preventing child maltreatment both to reduce childhood suffering and to alleviate an important risk factor for later health problems.
