Exploring Daily Physical Activity and Nutrition Patterns in Early Learning
Settings:
Snapshots of Young Children in Head Start, Primary, and After-School Settings
Introduction
In this study, children in the age range of 4-7 year olds were chosen as they
are at a critical juncture with respect to the development of attitudes,
preferences, and daily physical activity and play (structured and
unstructured) routines. In addition, over 25% of 2-5 year-old children in the
U.S. are at risk for overweight and obesity (Birch and Ventura 2009). Excess
weight among children under the age of 6 has not been well researched and
little is known about the most effective way to prevent obesity within this
population. However, there is increasing attention being given to this age
group. The White House Task Force on Childhood Obesity submitted a report in February
2011 identifying settings, programs and policies that support the prevention
of obesity for children during their first five years of life (F as in Fat 2010 p.
68). During these early years, children transition from drinking breast milk
or formula into eating modified adult diets. They are exposed to thousands of
meals, commercials, and other marketing strategies that will shape their
perceptions of what is normal, what and how much to eat, and what they like
and dislike (Birch and Ventura 2009).
Children are born with a preference for sweet tastes and by 4 months of
age they also begin to prefer salty tastes. These preferences can make it
challenging to promote healthy eating patterns if young children are
1
repeatedly exposed to modern, processed foods that are high in sugar and salt.
However, research has shown that children can learn to prefer healthy foods if
appropriate feeding practices in supportive and positive social contexts are
used (Birch and Ventura 2009). During these first five years of life,
important behavioral norms have been established in terms of food preferences,
cultural eating styles, and food expectations (Birch and Ventura 2009).
Review of the Literature
There are few research studies that focus on the direct voices of young
children related to their physical activity and nutrition routines in early
learning settings. Recent research efforts are summarized below. In a recent
report (Administration for Children and Families 2010), an effort was made to assess
children’s daily physical activity and nutrition in Head Start centers in the
U. S. In the spring of 2006, Head Start Region III provided 53 Head Start
programs with a 2.5-day training-of-trainers (TOT) event for up to five staff
members per program. The trainers and Region III staff encouraged participants
to tailor the enhancements to their own programs. During the training,
participants gained hands-on experience with the use of music and songs
through several activities that featured an animated character named “Choosy”
(Choose Healthy Options Often and Start Young). Choosy was introduced as a
potential mascot or role model that encourages children to engage in physical
activity and to practice healthy eating habits. While the majority of programs
reported that children enjoyed activities, eight of 26 Stage 2 programs
encountered some difficulties getting children to eat new foods or try new
2
activities. To address this, teachers reported encouraging children to try
small “no thank you” or “thank the cook” bites of food when new (or
traditionally avoided) foods were offered. Teachers also worked with children
who were reluctant or embarrassed to dance by giving them Choosy cutouts to
wave until they got used to doing the movements and felt more comfortable.
In another study, Goodway and Robinson (2006) developed and assessed an
early intervention with young children, SKIPing toward an Active Start
Promoting Physical Activity in Preschoolers. In an assessment of Project SKIP,
the authors found ways to infuse regular physical activity into early
childhood classrooms; witnessed significant improvement of motor skills and
perceived physical competence of children receiving the curriculum; observed
remediation of motor delays; and developed strategies to educate teachers
about the importance of physical activity and the means to promote an active
start (Goodway & Branta 2003).
According to longitudinal data from the Framingham Children’s Study,
there is a strong effect of low levels of physical activity on body fatness of
young children (Moore, l. l., Nguyen, U. D. T., Rothman, K. J., et al. 1995).
Children were studied from the age of 3-5 though enrollment into first grade
and demonstrated the importance early childhood behaviors have on obesity
risk. Another study examined the relationship between obesity in preschool-
aged children and exposure to 3 household routines: regularly eating the
evening meal as a family, obtaining adequate sleep, and limiting screen-
viewing time (Anderson and Whitaker 2010). Using data from the Early Childhood
Longitudinal Study (ECLS), researchers found that the prevalence of obesity
3
was 14.3% among children exposed to all 3 routines and 24.5% among those
exposed to none of the routines. Preschool-aged children exposed to the 3
household routines of regularly eating the evening meal as a family, obtaining
adequate nighttime sleep, and having limited screen-viewing time had a 40%
lower prevalence of obesity than those exposed to none of these routines.
There is a need for more refined research on physical activity and young
children in order to better understand factors that can influence children’s
physical activity levels. These include health-related factors such as body
mass index (BMI) and other health conditions. Two recent studies focused on
possible relationships between physical activity and body mass index. In a
study examining the association between objectively measured physical activity
(PA) and body mass index (BMI) of 281 children (55.9% boys) aged 4 to 6 years,
PA was measured by accelerometer (Vale et al 2010). Children were categorized
as non-overweight and overweight/obese. Results indicated that vigorous and
moderate intensity levels of PA were not associated with BMI; however, a
higher proportion of overweight/obese children were classified as low-vigorous
PA compared to their non-overweight peers (43.9% versus 32.1%, respectively).
Logistic regression showed that children with low-vigorous PA had higher odds
ratios to be classified as overweight/obese compared to those with high-
vigorous PA. These data suggest that vigorous PA may play a key role in the
obesity development already at pre-school age and needs further investigation.
A second study (Dunton et al 2012) of largely Hispanic and non-Hispanic
white children (N = 4550) with a mean (SD) age at study entry of 6.60 years
was conducted to determine whether participation in organized outdoor team
4
sports and structured indoor non-school activity programs in kindergarten and
first grade predicted subsequent 4-year change in body mass index during the
adiposity rebound period of childhood. After adjusting for several
confounders, BMI increased at a rate 0.05 unit/year slower for children who
participated in outdoor organized team sports at least twice per week compared
with children who did not. For participation in each additional indoor non-
school structured activity class, lesson, and program, BMI increased at a rate
0.05 unit/year slower, and the attained BMI level at age 10 years was 0.48
units lower. Results from this study suggested that engagement in organized
sports and activity programs as early as kindergarten and the first grade may
result in smaller increases in BMI during the adiposity rebound period of
childhood.
In addition, the research literature reflects higher rates of childhood
obesity among low-SES, Hispanic, and African-American children. Thus, in the
study being reported, an emphasis is placed on 4-7 year olds from those
populations who are served by diverse community-based centers and agencies. In
the selected county in the southeast part of the U.S., the majority of low-SES
children, including Hispanic and African-American children, are served in the
federally funded Head Start programs and the state-funded 4K programs. Primary
classrooms selected for this research project were in the same neighborhoods
and communities as the Head Start and 4K classrooms. Community recreation
centers also serve a cross section of SES child and parent populations in this
county. High-quality, early childhood programs are seen as a critical route by
which societal problems of poor health, education shortfalls, and crime can be
5
prevented (Mission: Readiness 2009). In the southeastern state in which the
study being reported was conducted, 50% of four year olds were in a state or
federally funded pre-kindergarten program in 2008 (Mission: Readiness 2009).
Head Start is the nation’s largest kindergarten program for at-risk children
(Mission: Readiness 2009). Head Start has developed a promising obesity
prevention and health promotion curriculum called “Hip-Hop to Health” which is
currently being evaluated by the University of Illinois for its impact on body
mass index and obesity related behaviors (ClinicalTrials.gov). Unfortunately,
Head Start only has funding to serve fewer than half of the eligible children
in the U.S. (Mission: Readiness 2009). Thus, there is a need to expand and
refine the research on possible relationships between low-income status,
ethnicity, gender, and nutrition status at home and in the early childhood
program, and levels of physical activity of young children 4-7 years of age.
Research Question
The purpose of this research project was to gain a greater understanding of
daily routines of 4-7 year olds regarding nutrition and physical activity.
The settings selected for this study included Head Start 4K, primary, and
after-school learning environments in a city in the southeast. Specifically,
this exploratory and observational study of a subset and representative sample
of 4-7 year olds in community-based early learning settings focused on the
following research question: What are typical daily physical activity and nutrition patterns in
community-based early learning settings for young children 4 to 7 years of age in the United States?
