Background: Identifying lifestyle factors such as physical activity (PA) patterns and eating
behaviors of children may be beneficial in implementing interventions in urban elementary
schools. Purpose: To examine PA levels and self-efficacy (SE) in PA and health eating (HE)
of third, fourth, and fifth graders in 3 low economic elementary schools in an urban setting.
Method: Students (N ¼ 295) were administered SE in PA and HE inventories and given Omron HJ7201TC pedometers. Results: Girls had significantly (P , .05) higher goal setting for healthy food choices (4.34 ^ 0.75) and decision making for healthy food choices
(3.85 ^ 0.89) than boys (goal setting: 4.11 ^ 0.87; decision making: 3.20 ^ 1.05). For step
counts per weekday (SWKD), boys (7354.88 ^ 2631.44 steps/day) had significantly
(P , .05) higher steps than girls (6273.87 ^ 2259.00 steps/day). Third and fifth graders (third: 7112.48 ^ 2564.13 steps/day; fifth: 7189.35 ^ 2470.57 steps/day) had significantly
(P , .05) higher steps than fourth graders (6172.21 ^ 2350.32 steps/day). For step counts per
weekend (SWKEND), no significant (P . .05) differences existed for gender (girls: 5732.38 ^ 3267.16 steps/day; boys: 6050.59 ^ 3564.21 steps/day) or grade level (third:
6486.23 ^ 3282.34 steps/day; fourth: 5605.74 ^ 3381.45 steps/day; fifth:
5617.51 ^ 3513.54 steps/day). A significant positive relationship was found for goal setting
for PA and SWKEND (r ¼ 20.178, P ¼ .033). In addition, significant relationships existed for transport questions, specifically, goal setting for PAwas positively related to the number of
times walking to school (r ¼ 0.142, P ¼ .036) and decision making for PA was negatively related to the number of times a student took the bus per week (r ¼ 20.139, P ¼ 0.33). Translation to Health Education Practice: An urban setting may influence the amount of
PA due to accessibility and opportunities to engage in PA.
BACKGROUND
Childhood lifestyle factors, such as a poor diet and physical
inactivity, have been recognizedas risk factorsfora multitude
of chronic health conditions that may have ramifications in
adulthood. 1 Both diet and physical activity are critical
components to the energy balance equation. Though
controversy may exist regarding which aspect plays a more
dominant role, proper management of both components can
assist one in achieving a healthy body weight and reduce the
onset of chronic diseases. 2 More recently, a lack of physical
activity associated with compromised health and well-being
has been termed exercise deficit disorder (EDD). 1 Only 42%
of children aged 6-11 years and 8% of adolescents (aged 12-
19 years) meet the current physical activity recommendations

children to accrue daily a minimum of 60 minutes of
moderate to vigorous physical activity. 3,4
The prevailing concern regarding physical inactivity and
dietary behaviors of children is the increased risk for
obesity. Childhood obesity has the potential for devastating
health consequences. Obesity has been well established as a
risk factor for a wide array of chronic hypokinetic diseases
including coronary heart disease, type II diabetes,
hypertension, and certain cancers. Obese children are
twice as likely to be obese as adults compared to nonobese
children. 5 Thus, it is critical to examine factors such as
physical activity and perceived confidence to make
decisions about healthy eating and physical activity with
the elementary school population, which can provide
important information to aid in obesity prevention.
In addition, minority children are at a higher risk for
being overweight or obese. Racial and ethnic disparities do
exist for prevalence of obesity. There are significant racial
and ethnic disparities in obesity prevalence among U.S.
children and adolescents. From National Health and
Nutrition Examination Survey 2007-2008 data, Hispanic
boys were significantly more likely to be obese than non-
Hispanic white boys, and non-Hispanic black girls were
significantly more likely to be obese than non-Hispanic
white girls. 6 Previous research demonstrated that minority
girls obtained less steps/day than their Caucasian grade-
level counterparts. 7 Understanding activity patterns and
decision-making perceptions of children may help to
understand reasons why these disparities exist.
A multidisciplinary approach is most appropriate for
tackling EDD, including involvement of schools (physical
educators and health educators), community health
specialists, health care providers, and parents to identify
children who do not meet physical activity recommen-
dations. 1
Identifying children who do not meet such
recommendations is considered an important initial step in
the battle against EDD; however, just as important is
understanding why recommendations are not being met.
Exploring children’s efficacy toward physical activity and
healthy eating behaviors may provide additional infor-
mation that could assist with intervention strategies. Using
social cognitive theory (SCT), the behavior, environment,
and individual were examined in urban Latino fourth and
fifth graders. 8,9
Physical activity (PA) was measured using
acclerometers, and self-efficacy, outcome expectancy,
social support, and physical/social environmental factors
were measured as variables of SCT. Gao found that self-
efficacy and social support were positive predictors for PA. 9
In addition, Bean et al. examined SCT during a PA
intervention in elementary school girls. 10
They found that
self-efficacy and PA were improved after a PA intervention
and concluded that structured PA programs can aid in
improving self-efficacy in elementary school girls.
The current study collaborated with elementary school
physical education teachers in an urban setting to examine
physical activity levels through the use of pedometers. Step
counting using pedometers is widely accepted by research-
ers and practitioners for assessing physical activity and
establish comparisons of step counts per day by gender of
children 6-12 years. 11,12
Daily step counts of 15 000 for
males and 12 000 for females were optimal in relation to
physical activity levels to establish a healthy body weight. 13
Steps per day from previous researchers were reported from
children grades 5-7 as 12 513 steps/day on weekdays (boys
13 523 ^ 3815; girls 11 737 ^ 2997) and 8820 steps/day on
weekends (boys 9431 ^ 4934; girls 8389 ^ 3943). 11
Current research suggests that mode of transportation to
and from school influences step-defined physical activity in
youth, in which nonactive commuters (car or bus) had fewer
weekday steps than active commuters. 7,14
Active transport
to schools has been reduced. In 1969, approximately half of
elementary and middle school children in the United States
walked or biked to school. By 2009, only about 13% of this
same age group walked or biked to school. 15
Additionally,
activity rates are reportedly lower in at-risk children, which
can be defined as children who come from economically
challenged backgrounds and can include minority groups
and single-parent families. 16-18
Purpose
The purpose of the current study was to examine the PA
levels among urban children living in a low economic
setting, as well as efficacy toward physical activity and
eating habits.
METHODS
Participants and Setting
Participants (N ¼ 295) were third, fourth, and fifth graders at 3 elementary schools in Springfield, Massachusetts. The 3
elementary schools were identified as low economic
schools. Total enrollment for grades 3-5 at School A was
134 and 59 students participated in the study (44%). Total
enrollment for grades 3-5 at School B was 227 with 96
students participating in the study (42%). For School C,
there were 146 total students in grades 3 to 5 and 94 students
participated in the study (64%). Please refer to Tables 1 and
2 for demographic data for each school as well as data for
the district and state. Data were collected during the 2012-
2013 year.
Permission to collect data was received by the
Institutional Review Board at the first author’s institution
and the Assessment, Research and Accountability Office of
Springfield Public Schools. Parental permission was
obtained; letters were sent home with students written in
the first language (English, Spanish, or Vietnamese) of the
parents/guardians.

Inventories and Instruments
The Physical Activity and Healthy Food Efficacy Scale for
Children (PAHFE) 19
was used to assess children’s goal-
setting and decision-making efficacy for physical activity
and healthy food choices. Construct validity evidence for
four subscales: Goal-Setting for Physical Activity (GSPA),
Goal Setting for Healthy Food Choices (GSHF), Decision
Making for Physical Activity (DMPA), and Decision
Making for Healthy Food Choices (DMHF) has been
established. 19
In addition, internal consistency ranged from
0.59 to 0.87 for the 4 subscales. 19
Data were collected that provided information on how
many days participants walked to school, took the bus,
brought their lunch, and ate school lunches and/or break-
fasts. OMRON HJ-720 ITC Pedometers (Omron Healthcare,
Lake Forest, IL) were used to assess PA. Omron HJ-720ITC
Pedometers display aerobic steps in minutes during aerobic
activity and total number of steps during the day. Advanced
Omron Health Management Software allows tracking of
daily, weekly, monthly, and yearly progress. Validity
evidence has been reported during treadmill use and over-
ground walking for the HJ-720ITC. 20,21
Procedures
Upon approval from the Institutional Review Board and
Assessment, Research and Accountability Office of the
Public School system, the principals and physical education
teachers at each school were contacted to receive
permission to collect data. Once approval was granted,
permission letters were sent home with each child in the
third, fourth, and fifth grades at each elementary school.
Permission slips were collected in each child’s physical
education class. Data collection occurred in physical
education classes for all students at all schools from
October 2012 to April 2013. School A’s data collection
period was from March to April 2013. School B’s data
collection was from January to February 2013, and school
C’s was from October 2012 to January 2013. For each grade
level, children take physical education biweekly.
In addition, for each grade level, there were 2 to 3
classrooms per grade level. At each school, we collected
data from one class in each grade level at a time. During the
first day of physical education for the week, students were
divided into 3 to 4 stations depending on class size. The first
station was used to complete the PAHFE and demographic
information. At the station, a researcher explained how to
fill out the inventory and stayed with students in the event
that they had any questions. At the second station,
pedometers were calibrated by having students walk 10
normal steps alongside a tape measure. The distance to walk
10 steps was recorded in inches and this information was
inputted into the assigned pedometer. Pedometers were
given to each student after calibration. Students were
instructed to wear the pedometer on the right side of their
body for 7 days. At the completion of 7 days, pedometers
were returned and data were downloaded from each
pedometer. Daily step counts were recorded per weekday
and per weekend from each student. Once one class at each

grade level had completed their 7 days, we collected data on
the next class and this continued until data collection was
complete at each school. As part of their physical education
classes, students were already exposed to wearing
pedometers before the start of the study. At each school,
students had worn pedometers as part of their physical
education class before. Therefore, an accommodation phase
was not included as part of the study.
Statistical Analysis
Differences among grade level (third, fourth, and fifth) and
gender were examined for weekday and weekend step
counts and subscale scores on the PAHFE. The subscales
included physical activity self-efficacy (SE) and healthy
eating SE. A total of two 2 £ 3 independent groups factorial analyses of variance were computed for weekday and
weekend step counts. The 2 independent variables included
gender (male and female) and grade level (third, fourth,
and fifth grade). For PAHFE subscale scores, a 2 £ 3 independent groups factorial multiple analysis of variance
was computed. Pearson’s product moment correlation
analyses were performed to examine the relationship
between PAHFE subscale scores and weekday and weekend
step counts. In addition, we examined the relationship
between PAHFE subscales, PA, and transport questions.
The number of times a student walked, took the bus, or was
driven by car to school was correlated with PAHFE
subscales and PA. All statistical analyses were conducted
using IBM-SPSS version 21. Alpha levels were set at
P ¼ .05.
RESULTS
Approximately 81% of the participants took the bus or were
brought by car 5 days per week, whereas only 12% walked
to school 5 days per week. Approximately 65% of
participants had school lunch at school 5 days per week
and 47% had the school breakfast. Initially, a total of 295
students participated in the study. The individual infor-
mation–centered approach was utilized to recover step
count missing data. 22 Only students with 2 or fewer missing
days were used to recover missing data for weekday steps
and students who had at least one weekend day were used to
recover missing data. In addition, only days in which
participants wore their pedometer for 6 or more hours were
included for analysis. Across grade level, a total of 243 data
points were used for weekday steps and 162 data points
were used for weekend steps. Step counts per weekday
(SWKD) and step counts per weekend (SWKEND) were
averaged.
No significant interaction (P . .05) existed for the subscales of the PAHFE for gender or grade level. There
was, however, a significant main effect for gender
(l ¼ 0.92, P ¼ .003). Univariate F tests were used to determine which subscales were significantly different for
gender. GSHF and DMHF were found to be significant, F(1,
194) ¼ 4.00, P ¼ .02; F(1, 194) ¼ 4.88, P ¼ .03. For both subscales, girls had higher subscales scores (GSHF:
4.34 ^ 0.75; DMHF: 3.85 ^ 0.89) than boys (GSHF:
4.11 ^ 0.87; DMHF: 3.20 ^ 1.05). No significant inter-
actions were found for SWKD or SWKEND step counts For
SWKD, boys (7354.88 ^ 2631.44 steps/day) had signifi-
cantly (P , .05) higher step counts than girls (6273.87 ^ 2259.00 steps/day). In addition, third and fifth
graders (third: 7112.48 ^ 2564.13 steps/day; fifth:
7189.35 ^ 2470.57 steps/day) had significantly (P , .05) higher step counts than fourth graders (6172.21 ^ 2350.32
steps/day). For SWKEND, no significant (P . .05) differences existed for gender (girls: 5732.38 ^ 3267.16
steps/day; boys: 6050.59 ^ 3564.21 steps/day) or grade
level (third: 6486.23 ^ 3282.34 steps/day; fourth:
5605.74 ^ 3381.45 steps/day; fifth: 5617.51 ^ 3513.54
steps/day). SWKEND step counts was significantly related
to GSPA (r ¼ 20.178, P ¼ .033). In terms of transport responses and PAHFE subscale scores, significant relation-
ships were found for number of times walking to school and
GSPA (r ¼ 0.142, P ¼ .036) and number of times taking the bus and DMPA (r ¼ 20.139, P ¼ .033). In addition, for the questions regarding food, the number of times bringing
lunch and GSHE were significantly related (r ¼ 20.149, P ¼ .030).
DISCUSSION
The current study examined the physical activity levels and
efficacy of physical activity and healthy eating of third,
fourth, and fifth graders from 3 urban elementary schools.
For the subscales on the PAHFE, differences were found
between boys and girls for the subscales for healthy eating.
For GSHF and DMHF, girls had higher self-efficacy scores
than boys. Differences in SWKD steps existed among grade
level and gender. Boys had higher step counts than girls and
third and fifth graders had higher step counts than fourth
graders. SWKD and SWKEND were less than reported by
previous researchers. 14 Average weekday and weekend step
counts for the participants were below the average values
reported from previous studies with similar age groups 21,23
and recommended levels for boys (15 000/day) and girls (12
000/day). 12
Lower average step counts may be linked to
more time spent in sedentary behavior. 11
In addition,
relationships among PAHFE subscales and PA as well as
PAHFE subscales and transport data were examined.
A relationship was found for SWKEND steps and GSPA.
As GSPA scores increased, the number of steps on the
weekend decreased. For transport data, relationships were
found for GSPA and number of times walking to school.
As the number of times a child walked to school increased,

so did the scores for GSPA, indicating greater self-efficacy
in children with more times they walked to school per week.
DMPA was found to negatively relate to the number of
times a child took the bus. Therefore, students who had
higher DMPA scores regarding how sure they can be to be
physically active was related to fewer times per week taking
the bus. Finally, GSHF was found to negatively relate to the
number of times students brought their lunch. The higher
the goal-setting score, the fewer number of times a student
brought his or he lunch. One should approach these
significant relationships with caution, however. Given the
number of correlations that were run (20) and the relatively
low correlations found, one may assume that this was due to
the sample size and may not be meaningful. 24
Though SE has been found to improve with higher PA,
this was not the case in the present study. 9,10
Gao utilized
accelerometers and, like this study, examined PA for
7 days. 9 Only Latino schoolchildren were studied. For the
current study, ethnicity was not collected by each
participant. Examining differences among ethnic groups
may be a more accurate way to examine PA patterns in
children. Bean et al. also found improved SE among African
American girls; however, their study utilized a self-report
of PA, namely the Youth Risk Behavior Survey. 10,25
The
self-report data may have been influenced by social
desirability bias.
The current study determined that only 12% of the
participants walked to school 5 days per week, which may
explain, in part, the lower average step counts. Minority
youth who actively commute are more likely to meet
physical activity recommendations than nonactive commu-
ters. 7 Youth who actively commuted to school were found
to average 1700 to 2300 more steps/day. 26
Total steps per
day may influence body composition (percentage body fat,
body mass index, and waist circumference), systolic blood
pressure, and VO2 max. 27,28
Even when accounting for the potential reduction in steps
per day due to transportation mode, the sample studied still
had substantially lower step counts. Additional contributing
factors may be climate during the data collection periods
and the physical environment of the schools. As noted
earlier, data were collected in the northeast region during
the months of October–April during the 2012-2103 school
year. Typically colder temperatures during these months
may have been a factor. Lower average step counts may also
be attributed in part to the urban setting, in which low levels
of step-defined physical activity (,5000 steps/day) is linked to a lower household income.
11 The Centers for
Disease Control and Prevention identifies physical environ-
ment as a potential factor reducing the likelihood that
physical activity guidelines will be met. 3 The lack of safe
locations for activity, parents’ perceptions of environment
safety, and lack of equipment were identified as barriers to
physical activity, which are often a concern with urban
environments. Additionally, the cost associated with
physical activities may account for low step counts in the
current study. On average, 82% of the students at the
elementary schools were from low-income families.
Though we did not specifically examine the physical
environment of the specific school locations, one may infer
that given the urban and low economic environment that
these children lived in that these barriers may play a role in
the lack of physical activity. The low physical activity
trends observed in this urban population stress the
importance of continued research in urban schools to help
fully understand the barriers involved with such negative
health conditions.
Though the information that was gleaned from this study
is telling, there were a number of limitations. Firstly, body
mass index data were not collected because 2 of the 3
schools did not agree to access the student data on height
and weight. Having body mass index data of the children
may have provided further evidence of the relationship of
PA and body composition in at-risk youth. Based on the
inactivity of our participants, we can only speculate that
these children are also at a higher risk for being identified
as being obese. Secondly, though children were very
compliant with wearing pedometers for 7 days, some data
were not usable because students did not wear their
pedometers long enough to meet the threshold of usable data
(at least 6 hours), especially for weekend steps. Finding
ways in which to remind or encourage students to wear the
pedometers for the requested time period is suggested.
TRANSLATION TO HEALTH EDUCATION PRACTICE
Step-defined physical activity using pedometers may be an
effective manner to determine lifestyle habits during
childhood, which may influence eating habits and physical
activity in adulthood. Low-income households, an urban
setting, and environmental factors may impact upon
attaining physical activity requirements. Mode of commut-
ing to school for youth and school-supplied meals may be
barriers to attaining physical activity recommendations and
avenues for intervention. Continued research in identifying
less active populations, environmental barriers, and
attitudes toward behaviors will dictate prevention measures
needed to impact upon the childhood obesity epidemic. The
low physical activity observed in this study underlines the
importance of continued research in urban schools to help
fully understand the factors involved with such negative
health conditions.
