Background: Intersectoral perspectives of health are present in the rhetoric of the sustainable development goals. Yet its descriptions of systematic approaches for an intersectoral monitoring vision, joining deter-
minants of health, and barriers or facilitators to accessing healthcare services are lacking.
Objective: To explore models of associations between health outcomes and health service coverage, and health determinants and health systems responsiveness, and thereby to contribute to monitoring, analysis, and
assessment approaches informed by an intersectoral vision of health.
Design: The study is designed as a series of ecological, cross-country regression analyses, covering between 23 and 57 countries with dependent health variables concentrated on the years 2002�2003. Countries cover a range of development contexts. Health outcome and health service coverage dependent variables were derived
from World Health Organization (WHO) information sources. Predictor variables representing determinants
are derived from the WHO and World Bank databases; variables used for health systems’ responsiveness are
derived from the WHO World Health Survey. Responsiveness is a measure of acceptability of health services to
the population, complementing financial health protection.
Results: Health determinants’ indicators � access to improved drinking sources, accountability, and average years of schooling � were statistically significant in particular health outcome regressions. Statistically sig- nificant coefficients were more common for mortality rate regressions than for coverage rate regressions.
Responsiveness was systematically associated with poorer health and health service coverage. With respect to
levels of inequality in health, the indicator of responsiveness problems experienced by the unhealthy poor
groups in the population was statistically significant for regressions on measles vaccination inequalities between
rich and poor. For the broader determinants, the Gini mattered most for inequalities in child mortality;
education mattered more for inequalities in births attended by skilled personnel.
Conclusions: This paper adds to the literature on comparative health systems research. National and international health monitoring frameworks need to incorporate indicators on trends in and impacts of other
policy sectors on health. This will empower the health sector to carry out public health practices that promote
health and health equity.

Introduction In the first decade of the twenty-first century, the World
Health Organization (WHO) played a leading role in
harmonizing health systems’ performance assessment ap-
proaches through the development of relevant conceptual
frameworks (1�4). These frameworks refer to five health system goals that are achieved through the intermediate goal
of coverage of the population with needed health services.
According to these frameworks, different combinations of
health systems’ functions such as stewardship, financing, or
service delivery can be evaluated based on how well they
improve the intermediate and final goals. The final goals are
improvements in: population health levels, population health
equity, levels of health systems’ responsiveness to the

legitimate expectations of the population, responsiveness
equity, and fairness in financial contributions. When con-
sidering these frameworks and the associated monitoring
approaches they have generated in the context of the
sustainable development goals (SDGs) (5, 6), one can
make several observations concerning potential areas for
improvement. We focus on two areas for improvement for
the purposes of this paper.
A first area for improvement in these frameworks is to
address the neglect of the critical role of determinants
beyond the health sector on population health. From
the leading nineteenth century German doctor, Rudolf
Virchow, to the present-day discussions on sustainable
development, there is general recognition that average
levels of population health and health inequities arise from
factors beyond health care and the health systems’ direct
control. This implies augmentation of the original WHO
frameworks mentioned above to include causal pathways
beyond service coverage. As Hippocrates observed, social
and environmental factors affect health directly. Yet social
and environmental factors may give rise to additional
problems with access to health services, thus modifying or
even augmenting their direct effects on population health.
In order to be comprehensive and efficient, health per-
formance frameworks and associated monitoring should
track trends in these broader determinants. This will allow
the health sector to detect, understand, influence, antici-
pate, and possibly even alter the health impacts of decisions
in other sectors. The WHO Commission on Social Determi-
nants of Health argued in 2008 that impacts of health
determinants, in particular social determinants related
to the distribution of power, money, and resources, were
even more important for addressing health equity (7).
A second area for improvement relates to the develop-
ment of measures of non-financial barriers to access to
health services. We use the term ‘non-financial’ to distin-
guish a set of barriers that complement the financing
of direct medical expenses. The so-called non-financial
barriers may have components related to indirect costs
(e.g. food, fear of loss of income), but also include other
barriers related to acceptability and access (e.g. treatment
with dignity and non-discrimination). Non-financial bar-
riers to health service access are related to health deter-
minants. For example, the lack of transport in rural areas
may result in longer travel distances to health facilities and
differential health service access for disadvantaged groups.
At the same time, the lack of transport can affect access
to work with direct impacts on health through reducing
family time or the length of periods of breastfeeding.
Although non-financial outcomes of health systems
were reflected in WHO’s original frameworks by the con-
cept of health systems’ responsiveness, advances in routine
application in measurement and monitoring have been slow.
Responsiveness is the degree to which legitimate expecta-
tions of the population with respect to non-clinical aspects
of health care or public health services were actually
met (1). It is measured through large representative general
population household surveys, or targeted surveys among
recent care users. The responsiveness domains are, in
alphabetical order: autonomy, choice, communication,
confidentiality, dignity, prompt attention, (quality of) basic
amenities, and (access to family and community) social
support. The work of Donabedian, Tanahahsi, and others
suggest that responsiveness has a direct positive relationship
with service coverage and the final target, health (8�11). We therefore plead for a broader measurement and
monitoring framework, incorporating responsiveness and
determinants, to be applied to evaluating health systems
performance. To investigate the case for this empirically,
this paper describes the development of analytical models
that use data on health systems responsiveness and indi-
cators of social and environmental determinants of health
for their association with key outcomes from the original
WHO frameworks. These key outcomes relate to average
levels of population health and health equity and the
intermediate goals of health service coverage and service
coverage equity. These outcomes of interest are important
in light of the SDGs, as several measures of average levels
of health and universal health coverage (UHC) have been
accepted as part of the SDGs monitoring framework (12).
In our paper, responsiveness and determinants are eval-
uated in terms of their instrumental contribution to
health and health service coverage.
This paper investigates the association between popula-
tion health outcomes, UHC, and responsiveness, and the
role of determinants. We explore regression models, vari-
ables, and country-level indicators for determinants and
responsiveness using cross-sectional data for between
23 and 57 countries. We observe whether a small basket
of theory-supported determinants indicators explain
expected linkages at the ecological level to health and
coverage outcomes.
Methods The approach was: 1) to define a hypothesis-driven set
of variables representing health service coverage, health,
health systems responsiveness, health systems financial
protection, and broader societal factors referred to as
health determinants, suitable to test relationships; 2) to
select and link accessible data sets for testing; and 3) to
conduct multiple regression analyses to assess the hy-
pothesized associations. The country set was confined to
those listed in the 57 face-to-face complete surveys of the
World Health Survey (WHS) (2002�2003; see Appendix 1), for which comparable health systems’ responsiveness
information is available.
Model
The analytical model that underpins the variables and
regression analyses of population health and service cover-
age in this paper is represented in Fig. 1. This describes

the main pathways related to how determinants and res-
ponsiveness, as instrumental variables, affect population
health and service coverage. It is derived from standard
literature of conceptual models or frameworks related to
how the broader society interacts with health systems
to ‘produce’ health (7, 13�15). In view of the broader analytical focus of this paper at this stage, these broader
conceptual frameworks were considered to provide more
relevant starting points than frameworks for monitoring of
health services (e.g. monitoring of UHC). The societal-level
models tend to show the role of determinants quite strongly.
The unique feature we added is the separate, instrumental
and therefore testable role given to responsiveness, assum-
ing that people-centredness matters for health and coverage
outcomes, thus representing a pathway in itself.
From left to right, Fig. 1 describes the pathways of
influence on population health and universal population
health service coverage. Starting first with the blue block,
the analytic framework assumes that ‘fixed’ characteris-
tics of population, society, and the health systems’ func-
tions determine the context for intermediate factors that
are more directly associated with health and coverage. These
‘fixed’ characteristics (left) are considered unchangeable
for a given period of time and result in multiple influences
on intermediate factors. The intermediate factors shown
in the centre column operate at the individual-level and
include exposures or access to health services, for which
empirical studies have shown more direct causative asso-
ciations with population health (average levels and health
equity) and health service coverage (average levels and
coverage equity) (on the right) (7). The intended analyses
focus on the pathways (i) determinants to health and
coverage (not distinguishing between iA and iB); (ii) res-
ponsiveness to coverage; and (iii) financial resources and
financial health protection to coverage. Pathway (iv) is
assumed as implicit. Given the importance of financial
protection for health service coverage, it was necessary to
model it, although the focus of the paper is on the addi-
tional roles of determinants and health systems responsive-
ness. Below we elaborate several generic implications of this
analytical model for structuring the analyses that follow.
Health outcomes
1. Two outcomes should be considered in the regression
models in order to cover two separate but important
measures of health systems performance: population
health and coverage of the population with essential
health services (population health service coverage).
2. The outcome measures tested as the dependent
variables should cover a spectrum of disease profiles
and health service interventions.
3. Equity measures of these main coverage and health
outcomes should also be considered in order to
assess specific pathways for inequities in health and
coverage.
Health determinants
1. Determinants as intermediate factors can be mea-
sured at the individual-level and aggregated to the
country-level, but they can also be measured by
policy variables.

2. Distributional measures of determinants measured
at the individual-level should be tested for model-
ling equity in health and health service coverage.
3. Health systems are key determinants of health and
health service coverage. Proxy measures of health
systems should be included in regression models
and should relate to levels of resources and financial
protection, given its importance as a determinant of
health service clinical quality and access (5).
The next sections focus on scoping recommended
dependent and independent variables outlined in the ana-
lytical model and on selecting the final data set for the
regression models.
Scope of variables
Health and coverage (dependent variables) Population health status can be represented by rates of
morbidity, mortality, the compound indicator life expec-
tancy, or self-reported health. Health service coverage
can be characterized by enrolment, utilization, or effective
service coverage rates (population in need receiving treat-
ment divided by the population in need). Coverage rates
can be measured comparably if morbidity�intervention combinations are standardized across countries (5). Similar
to other studies (16), the following additional criteria were
applied to select the final set of dependent variables:
1) completeness of the data for the time period and
countries; 2) a spectrum of health conditions or inter-
ventions covering reproductive, maternal and child health,
communicable diseases (the so-called ‘unfinished’ millen-
nium development goals), and non-communicable dis-
eases and injuries; and 3) variables for which country-level
inequality data were available. Inequalities in health out-
comes can be measured as gaps or concentration measures
describing between-group differences in aggregate health
outcome levels, where groups are defined by a ‘wealth’ or
‘income’ quintile (e.g. absolute or relative gap between
fifth and first quintiles), sex, geographic areas, and edu-
cational attainment (17).
Predictor and control variables (independent variables)
Health determinant variables (that are under the control
of policy sectors other than the health sector) can be
conveniently grouped into the following categories envir-
onmental quality, accountability and inclusion, and liveli-
hoods and skills (referred to as EQuAL). A variant of
these categories was discussed at an expert meeting held by
WHO (18). Based on these categories, a range of poten-
tially relevant country-level indicators were drawn from
a descriptive review of recent peer-review literature and
from key informant reports.
Environment quality indicators representing physical
exposures are: urban households living in ‘durable’ struc-
tures; population exposed to small/fine urban particulates
(PM10 or PM2.5) in concentrations exceeding WHO Air
Quality Guidelines; households using modern fuels/
technologies for all cooking, heating, and lighting activities;
health facilities with access to clean and reliable electricity;
population using a basic (improved) water source; the popu-
lation whose access to safe water sources and sanitation is
at risk from changing climate (19, 20); exposure to harmful
substances in the work environment, and broader physical
conditions in the work environment (e.g. night shifts,
length of working week). Social elements of housing are:
residential stability or affordability of neighbourhoods
(20); urban design or green space and safety, and for
products, enforceable and regulatory product quality
and labelling measures (21).
Accountability and inclusion indicators include: vio-
lence against women; ratios of female to male schooling
(attainment); social capital; self-reported gender inequal-
ity or discrimination; discrimination in laws and policies,
and related composite indices (e.g. World Bank Good
Governance database) (22).
Livelihoods and skills indicators include: child stunting
(23); caloric intake; household poverty; access to social
protection (e.g. cash transfers); value in work; associated
psychosocial exposures; employment relations (e.g. in-
formal or formal, own account/salaried � access to paid parental leave, old age pensions); maternal education and
birth spacing; child development; access to early child
development services, and social inequality (18, 23).
Responsiveness measurement is described in the litera-
ture (24, 25). The original eight responsiveness domains
can be regrouped by the EQuAL framework: basic
amenities and communication under Environmental qual-
ity; autonomy, confidentiality, dignity, and social sup-
port under Accountability and inclusion, and choice and
prompt attention under Livelihoods and skills.
Health systems pathways related to health system
availability and financing are characterized in terms of
levels of expenditure and financial protection coverage
(other factors less commonly considered are human re-
source levels) (4, 16). Out-of-pocket expenditure indica-
tors often represent financial protection coverage, with
higher levels representing higher copayments or low
financial protection coverage (16, 26), which are known
to be regressive (27).
Demographic and biological drivers of need are primarily
age and sex structure of the population. For our analysis,
such variables are controlled for as has been done
elsewhere (28).
Data sources and final data sets
Country-level indicators and data
In view of the scope of variables and indicators outlined
above, we scanned the range of potential data sources from
WHO (World Health Statistics; Global Health Observa-
tory) and World Bank (World Development Indicators
including the Worldwide Governance Indicators) databases.

Country-level data were obtained, in most cases for the
years 2002�2003. For responsiveness, we needed to calculate country-level measures from individual-level
data sets from the WHS. The WHO WHS data are the
only large publicly available cross-country and region
source with information on a range of health system res-
ponsiveness domains. Implemented between 2002 and
2004, the WHS data, acquired through nationally repre-
sentative and quality-controlled surveys, have been widely
used in the peer-review health literature (29). Its data on
responsiveness cover 57 countries and 151,848 respondents
(using public and private sector providers). The selection of
the remaining indicators was made for these 57 countries
classified by the United Nations Development Agency
in 2003 (30): 23 low-income countries; 13 lower middle-
income countries; 11 upper middle-income countries; and
10 high-income countries.
Table 1 lists the final indicator names, the number
of observations obtained, descriptive statistics, and data
sources (31�34). All data except for responsiveness were obtained as country-level indicators. The estimation of
country-level responsiveness indicators from the World
Health Survey individual-level data set (35) is described
in detail below.
Acquiring and linking data from different sources took
place between August and December 2014. Two consoli-
dated data sets were used for analyses. The final six health
and coverage average levels data set contained between
52 (coverage) and 57 (health) country-level records. The
final three data sets for health and coverage inequalities
consisted of 23 (country-level) records each.
Responsiveness indicators were derived from health
service user responses to the WHS for all 57 countries as
indicated earlier. Responsiveness level indicators were cal-
culated by averaging domain summations of individual-
level responses dichotomized from a five-point verbal
response scale (‘very good’, ‘good’ [0, no problem]
‘moderate’, ‘bad’, and ‘very bad’ [1, problem]). Dichot-
omizing the scale and standardizing by education and
self-reported health status make results less susceptible
to ‘reporting behaviour’ bias and more comparable across
countries (36). The final indicator calculated for the aver-
age level of responsiveness was: the frequency of report-
ing ‘a problem’ or ‘poor responsiveness’ in a particular
domain. The domains of prompt attention and dignity
were selected as they were among the two most important
domains across a wide range of countries (37), and illus-
trated two different faces of responsiveness as described
in the original WHO work (1): prompt attention, ‘client
orientation’ domain, and dignity, a ‘respect for persons’
domain. A composite responsiveness equity indicator was
used for outpatient services rather than having domain-
specific indicators. The responsiveness equity indicator
was the average percentage across domains of responsive-
ness problems reported in the bottom two wealth quintiles
for the less healthy in the population (those reporting
moderate, poor, or very poor health). Because of small
numbers, the bottom two wealth quintiles were used rather
than just the bottom. The wealth quintiles were based on
cross-country comparable asset indices and made avail-
able by WHO as part of the World Health Survey data
set (38). Like the poverty measure, this is not strictly an
inequality measure. However, it does measure the respon-
siveness experiences of disadvantaged groups, which could
explain inequities in health and coverage outcomes.
Neither the relative or absolute gap measures of inequality
for responsiveness showed any correlation with the
dependent variables.
Missing data procedures
Missing data were not extensive for the final analyses. The
missing data procedure followed used multiple imputa-
tion by chained equations as specified in the standard
Stata mi command routines and associated instructions
(39). Missing data for the dependent (health and cover-
age) country-level indicators were not filled and the
procedure was not necessary for the responsiveness and
health systems indicators. Missing data for the determi-
nants indicators were predicted from the country income
group (dummy) and total health expenditure per capita.
The following variables and observations were incomplete
before imputation: accountability and voice index (miss-
ing for Cote d’Ivoire, Congo, Sri Lanka); and mean years
of schooling for the population of 15 years or more in
2000 (which of the variables filled had the highest missing
rates, for 9 out of 57 countries: United Arab Emirates,
Bosnia and Herzegovina, Congo, Georgia, Israel, Lao
People’s Democratic Republic, Myanmar, Senegal, and
Tunisia). The percentage of the population below the
national poverty line in 2002 was only available for 35
countries out of 57 countries and therefore not filled.
Analyses
Standard univariate and bivariate descriptive analyses on
the dependent and independent variables preceded regres-
sion analysis (see Appendix 2). Normality of the distri-
bution was tested. With respect to dependent variables,
distributional characteristics required several transforma-
tions. The logarithmic transformation of the dependent
variables generally improved analytical properties. It was
necessary to log the mortality rates in order to normalize
the skewed data distribution (16, 40, 41). For predictor
variables, health expenditure per capita and the difference
in access to improved water sources also required log
transformation. These transformations do not affect the
principle relationships tested. Scatter plots were used to
assess the linearity of bivariate associations between pre-
dictor and outcome variables. Correlation matrices were
used to assess collinearity of predictors (the highest cor-
relation was a Pearson correlation coefficient of 0.75 for

Different regression models were tested: ordinary least-
squares (OLS) linear regression, OLS log-linear regression,
and Poisson and negative binomial maximum likelihood
regressions. Although OLS regressions are more com-
mon than Poisson-based models, it was appropriate to
try different models based on assumptions regarding
the outcome variable (42). Judging the appropriate form
of the model of the outcome variables required assess-
ing model fit statistics, considering the underlying data
generation mechanisms assumption, as well as a priori
assumptions regarding the impact of predictors on out-
comes variables. Model comparisons were undertaken
for the domains of dignity, prompt attention, and basic
amenities as these variables have high importance and
variance across countries (24, 37). Model comparisons for
mortality outcome variables, including log-linear regres-
sions and Poisson-based negative binomial models. The
negative binomial is a form of the Poisson that recognizes
the original count, and integer (non-negative) nature of
data, while relaxing assumptions regarding the mean equal
to the variance (high mean dispersion). It is arguably
preferred for mortality regressions (42, 43). Whereas
OLS model fit statistic uses R 2 , which ranges from 0 to 1,
with numbers closer to 1 representing higher fit, the
log-likelihood becomes more positive as fit improves.
Comparing models using the log-likelihood statistic
requires calculation of the likelihood ratio chi-squared
test ( �2 times the difference in the log-likelihood ratios between the baseline and fitted models).
Only negative binomial regressions were used in regres-
sions on average levels of health � maternal mortality, child mortality, and Tuberculosis (TB) cause of death
(mortality). For the aggregate levels of health coverage� population coverage of births by skilled attendants,
coverage with measles vaccination, and receiving Pap
smears � linear log and linear regressions were used. Final regression models for health outcomes and coverage levels
contained a total of six predictor variables (after poverty
rate was tested initially) and were each run twice in order
to have separate predictions for dignity and prompt
attention. This was done to reduce variables in a single
regression, given the sample sizes of 57 and high correla-
tions between responsiveness domain scores (Pearson
correlation coefficient, 0.85).
For regressions on inequalities, final models had only
four predictors at a time (only 23 countries). To select
the four predictors, once again, the pretesting of several
models was performed. Regression results shown are
selected from the model with the highest R 2
or the most
positive log-likelihood ratios (best fit) from the three
combinations of independent variables tested, which were:
1) out-of-pocket expenditure, responsiveness inequality,
difference in access to drinking water between urban
and rural areas, accountability, and voice, Gini (largest
number of variables); 2) out-of-pocket expenditure, re-
sponsiveness inequity, years of education (smallest number
of variables); and 3) responsiveness inequity, the differ-
ence in access to drinking water between urban and rural
areas, years of education, Gini. In all regressions, a larger
number meant greater inequity (favouring wealthier). In
results, regressions were presented for difference and ratio
properties of the three dependent variables (six regression
results).
Coefficients were assessed for statistical significance at
the intervals: B0.10; B0.05; and B0.001.
The negative binomial regression coefficients were
interpreted as an increase of x in an explanatory variable
multiplying the fitted mean mortality rate by exp(bx) (42).
Results
Comparing regression models for the role of
predictors of health outcomes
Table 2 displays the regression test results using maternal
mortality with the dignity domain for responsiveness
as an example. Four regression formats are shown: OLSs
linear and log-linear models (models 1�3), Poisson and negative binomial models (models 4�6). Comparisons of this nature were made for all outcome variables.
Comparing the model fit statistics for OLSs regression
shows better fit for log linear regressions (model 2). The
Poisson regression log-likelihood statistics indicate poor
fit relative to the negative binomials (more negative). In
the negative binomial regressions, compared with base-
line models (containing only population over 60 years),
both regression models likelihood ratio tests are adequate
to warrant inclusion of more predictors (pB0.000).
Specific experimentation showed that for all models,
the percentage of the population older than 60 years is sig-
nificantly associated with the level of maternal mortality.
This obvious demographic�biological need pathway will receive no further comment. Other variables show less
uniform patterns.
Using OLS regression (regression 1), lower maternal
mortality, without log transformation, is predicted by res-
ponsiveness but not by health expenditure per capita. This
result is contrary to theory-driven expectations. In regres-
sion 2, with outcome variables log transformed, there is an
association of maternal mortality with total health ex-
penditure per capita (natural log), but the association for
responsiveness is small and non-existent for years of
schooling and access to drinking water. Model 3, which
also treats the outcome variable as logged, adds as an
independent variable, the percentage of the population
below the national poverty line, which was available for
34 mostly lower and lower middle income countries out of
57. National poverty rates are associated with maternal
mortality [coefficient 0.03 (p�0.00)] as would be expected.

Again, the effect of national poverty rates swamps out
health expenditure per capita and accountability, which
may suggest that the log-transformation alone is insuffi-
cient to correct for the underlying distributional form.
Regression 5 introduces the country’s average level of
income (World Bank categories) as independent variables.
Income removes some effects of other variables, in parti-
cular for health expenditure per capita, responsiveness,
and years of schooling. Regression 6, on the other hand,
shows up these variables. Maternal mortality across coun-
tries is associated with health expenditure (coefficient:
0.26; p �0.03), with responsiveness barriers (coefficient: 0.29; p �0.05), and average years of schooling (coeffi- cients: �0.07; p �0.08). Although associations with accountability and access to water and sanitation are in-
significant, the clearer pathways related to health systems
and health service interactions make this model preferable
in our view, given that the health outcome maternal
mortality is usually associated with the lack of health
service attention at birth.
Regression models that explain aggregate
health levels
Six regressions of health outcomes and coverage rates
are shown in Tables 3 and 4 for two domains: 1) dignity,
and 2) prompt attention. Regressions otherwise contain
the same independent variables. The first regression column
shows the maternal mortality negative binomial regression
with dignity (repeated from Table 2, Model 6). The next
column in Table 3 shows the regression for child mortality,
then TB mortality rates, and so on.
Across Tables 3 and 4, one observes that statistically
significant coefficients for predictors are more com-
mon for mortality rate regressions than for coverage rate
regression. In Tables 3 and 4, column 3, there are a high
number of significant covariates, in the expected direction,
for child mortality on the one hand (all predictors except
adult education) and a low number for measles coverage
on the other hand (Tables 3 and 4, column 6). Respon-
siveness is statistically significant for all mortality regres-
sions but for only one of the service coverage (skilled
attendants). Higher percentages of responsiveness pro-
blems in countries are associated with increased maternal,
TB, and injuries mortality (Table 3, columns 2�4 and Table 4, columns 2 and 4), and reduced coverage of
the population with skilled birth attendants (Table 3,
column 5). On average, the effect sizes of responsiveness
on the dependent variable, measured in terms of numerical
percentages, are higher for service coverage than for mor-

tality rates. Using coefficient results in Table 2, and the
proportionate formula for interpreting negative binomial
regression coefficients, as described in the methodology
[exp b(x) �exp(0.29*0.10)], an increase in responsiveness problems by 10% increases mortality rates by 3% and
decreases service coverage rates by 5%.
Looking across indicators, access to improved drinking
sources is statistically significant in only one mortality
regression � child mortality � and one coverage regression � skilled attendants at birth. Accountability (and voice) is
statistically significant only in one mortality regression � child mortality. Average years of schooling is relevant
to one mortality outcome � maternal mortality � and to one coverage outcome � measles vaccination. Health expenditure per capita is statistically significant in four
out of six regressions (except TB mortality and measles
coverage).
Model fit within health outcomes regressions, as judged
by log-likelihood statistics, is best for maternal mortality
(LL ��359), followed by TB mortality (LL � �503) and child mortality. In health service coverage regressions,
fit as judged by the R 2
statistic is better for skilled atten-
dants at birth (R 2 �0.81) and Pap smear (R2 �0.55) than
measles vaccination (R 2 �0.37).
Qualitative changes are observed in the effects of
dignity versus prompt attention. For child mortality,
prompt attention barriers are not significant, whereas
dignity barriers are significant (pB0.05). On the other
hand, both dignity and prompt attention barriers are
highly significant (pB0.001) for TB mortality rate regres-
sions. However, effect sizes for TB are larger for prompt
attention responsiveness barriers than for dignity.
Regression models that explain aggregate health
inequalities
Table 5 shows regression results for health outcome
inequalities and service coverage inequalities as depen-
dent variables. Child mortality favoured combinations of
variable sets 1 and 3, whereas coverage inequality models
were best fitted with the smaller set of predictor variables
from set 2.
Responsiveness problems experienced by the unhealthy
poor groups were statistically significant only for measles
vaccination inequalities between rich and poor. Out-of-
pocket expenditure was statistically significant in predict-
ing coverage gaps for measles immunization. With respect
to the broader determinants, the Gini coefficient mat-
tered most for inequalities in child mortality between the

ities in births attended by skilled personnel.
Discussion This paper presents an exploration of different models
for understanding the linkages between health and ser-
vice coverage outcomes, and related health determinants,
including health systems’ responsiveness. We used a set of
cross-sectional analyses of different types of health status
and health service coverage rates to explore different sets
of determinants and health systems’ responsiveness indi-
cators across 57 countries. To our knowledge, this is the
first time that both health conditions and service coverage
rates are explained using determinants and ‘acceptability’
barriers of responsiveness.
The determinants’ indicators tested here were asso-
ciated with health in the expected directions as shown
elsewhere (17, 20, 21, 40, 41), which is reassuring with
respect to the findings for health systems’ responsiveness.
An interesting new finding is that responsiveness was
systematically associated with poorer health outcomes
and coverage in the areas of maternal mortality, child
mortality, TB mortality, skilled birth attendance coverage,
and Pap smears (not measles vaccination). The results
imply that both responsiveness barriers and health deter-
minants have quantifiable, separate associations with
health status and health service coverage. Responsiveness
complements the financial barriers indicators recom-
mended to be measured as part of UHC in the health
goal, SDG-Goal 3.
Our analyses also have implications for monitoring
health determinants in the SDGs. SDG-Goal 3 (health)
covers health outcomes and ‘UHC’ (6, 12). UHC in the
SDGs is defined as the degree to which health services
meet population healthcare needs without undue financial
hardship. Two metrics derived for its quantification are:
financial protection coverage of individuals, which is mea-
sured by the absence of so-called catastrophic direct
medical costs (5), and service or intervention coverage,
which is measured as the proportion of people, who need
particular well-accepted health interventions, receiving
them. Both metrics can also be expressed as coverage
inequality (by sex, education, income, and geographic
area) (17). Yet, these metrics do not explicitly track res-
ponsiveness barriers, or the wider panorama of social and
environmental determinants such as education of mothers
and income inequality, which are clearly important for
achieving good population health and effective health
service coverage.
The systematic testing of regression models, variables,
and indicators as illustrated in this paper, is useful for
determining which national comparable health determinants
indicators to track. Our findings show that several deter-
minant indicators are candidates. These include drinking

water coverage and coverage inequalities, poverty, mean
years of schooling, and income inequality. These are
candidates for both international and national use in
intersectoral monitoring frameworks that track health
determinants. Except for poverty, the data series are rela-
tively complete (poverty is more complete now relative to
2002�2004) and they complement SDG-Goal 3 (health). These indicators are also likely to be used by sectors
beyond health in monitoring other SDG goals (e.g. Goal
1 � poverty, Goal 4 � education, Goal 6 � water and sanitation, and Goal 10 � income inequality). Having the health sector in national contexts tracking a set of
determinant indicators is vital, as described in the Health
in All Policies approach (44). Tracking determinants
is statistically simple as well as efficient and provides a
rational for policy coherence if the same indicators are
already being used by another sector to monitor their
strategic performance. These data can also be used as
a bridge to build better information systems for health
impact assessments, thereby enabling anticipation of
health changes before they emerge as behavioural changes
in the population.
There are several limitations to our study. It consists of
data that are 12�13 years old. It is possible that, as health systems and development contexts have changed, other
patterns would have emerged if the study had been con-
ducted on current data (e.g. governance accountability
concepts can have altered). We also used a limited number
of variables. More recommendations for the use of vari-
ables in future research are discussed below. A further
limitation is that we only conducted relatively simple
cross-sectional analyses, which yielded information on
associations but specific longitudinal analyses should be
investigated in the future for more causative tracking of
health determinants. One example of a recent study that
used more sophisticated mathematical underpinnings is
Mondal and Shitan (45), which used path analysis and
found a significant association for low and lower-middle
income countries between life expectancy and mean years
of schooling. In more complex methodological studies,
there is a tendency for fewer health outcomes, predictors,
and countries to be analysed due to data availability
problems. Other typical enhancements to the analytical
approach are time-series analyses (46) and multi-level
analyses (20).
We were struck by the cross-country equity regression
results. Although much is known about measuring and
monitoring health and coverage inequalities (47), far less
is known about the predictors of the aggregate levels
of health inequalities. This is very important for under-
standing actions to improve health equity and which
determinants to monitor. Currently, there is little empiri-
cal literature using country-level health inequalities me-
trics (48, 49) as dependent variables. Our paper used gap
measures as dependent variables. Predictors were the Gini
index, differences in drinking water access, and health
systems responsiveness to poorer populations, which were
all relevant, but not for all health and service conditions.
For global monitoring of SDG-Goal 10, covering the
reduction of inequalities within countries, it would be
useful to know which determinants indicators are most
closely linked to health inequalities.
In the future, a wider range of indicators could be
tested for use in tracking health determinants as part
of the SDGs. We selected what appeared to be feasible
indicators, for some of which had available distribu-
tional information (i.e. for access to water). But several
additional examples of theory-driven indicators were
mentioned earlier. Variables already considered in the
cross-country literature are female education (45). In our
analysis, we used education overall, but further work
would explore female education. Kolves et al. (50) used
the Gini indices, unemployment rates, female participa-
tion in the labour force, GDP per capita, and divorce rates
to predict suicide rates. Fritzell et al. (41) found child
poverty rates and social spending were associated with
child mortality. For our data set of 57 countries, poverty
rates were too incomplete to use for all regressions. Another
study showed that paid maternity leave was also asso-
ciated with improved immunization coverage (48). These
studies illustrate the more specific indicators that require
further testing, including the importance of policy in-
dicators. Data sets on policy indicators related to the
labour market conditions for health may be of specific
interest in this regard (see the World Policy Analysis
Database: www.worldpolicycenter.org/).
A major obstacle to advancing empirical testing of
determinants and barriers or facilitators of health services
access, like responsiveness, is having both a holistic vision
of health, and the available data (3). As part of the
SDGs, the United Nations Secretary-General’s Indepen-
dent Expert Advisory Group on a Data Revolution for
Sustainable Development encourages the collection of
disaggregated data for monitoring equity across goals � most of which include important health determinants
(51). The follow-up of these recommendations will be very
important for any initiatives to track health determinants
and their population health and health equity impacts.
Investments need to be made to obtain better, disaggre-
gated data about the real sector of the economy, societal
well-being, and the environment (52). Health policy-
makers should advocate for better data collection and
disaggregation in other sectoral indicators in order to
identify common causes across sectors.
Conclusions In promoting monitoring of health determinants and
related barriers to health service coverage like responsive-
ness, the health sector will enhance public health pro-
motion, which is necessary for SDG-Goal 3, ‘attaining

healthy life for all at all ages’ (5). It is only when national
health monitoring by the health sector reflects the true
intersectoral scope of health, that accountability across
sectors for actions affecting health will be demanded by
the whole-of-society.
