Childhood
obesity has dire consequences and can lead to many childhood health
problems that persist into adulthood. According to the Center for
Disease Control and Prevention, obese children's health risks include
high blood pressure and high cholesterol, increase risk of type 2
diabetes, breathing problems, joint problems, fatty liver disease,
gallstones, heartburn and a greater risk of social and psychological
problems (Basics About Childhood Obesity 2011). Obese children are
more likely to become obese adults and the health concerns of
children are likely to continue or worsen.
Obesity
is measured using Body mass index. Calculated using a child's weight
and high, it does not measure body fat directly, but it is a
reasonable indicator of body fatness for most children and teens
(Basics About Childhood Obesity 2011). Children between the 85th
and 95th
percentile are classified overweight and above the 95th
percentile they are classified as obese (Basics About Childhood
Obesity 2011).
According
to data from the National Health and Nutrition Examination Survey,
17% of children and adolescents are obese and data
from the Pediatric Nutrition Surveillance System reports 1 in 7
low-income preschool-aged children is obese (Basics About Childhood
Obesity 2011). The prevalence of obesity in American children has
increased in the past 30 years and this great increase in obesity may
lead to increases in incidence of heart disease, diabetes, stroke,
and possibly cancer and is therefore projected to produce the first
decline in U.S. life expectancy since the Great Depression (Trasande
159).
In
his study “Environment and Obesity in the National Children's
Study,” Transande states, “The
recent explosive increase in prevalence of obesity reflects a complex
interplay among changes in individual behaviors; changes in community
structure, lifestyle, and the built environment; and possibly
exposures to certain synthetic chemicals, such as endocrine
disruptors, that may have the capacity to disrupt energy balance.”
(Trasande
159).
To
educate my sixth grade students about nutrition and obesity, I
researched the nutrition label and the effects of nutritional eating
at school. The ability to analyze a nutrition label and make good
choices in the cafeteria could have positive repercussions in
students' lives and help them combat obesity.
The
Nutrition Labeling and Education Act of 1990 mandated that all
packaged foods carry nutrition label-ing information presented as
standardized "Nutrition Facts" to provide accurate and
truthful information on packaged products (Misra
306).
According to Misra, “Label
users had diets lower in fat and higher in fruit and vegetable intake
compared with nonusers.” (306). Misra
found consumers were able to use food labels effectively only when
the task did not involve mathematical skill, so she recommends
“nutrition education for
adolescents should focus on understanding and using food labels
rather than on calculations.” (306).
Adolescents
need total nutrition more than at any other time of their life, yet
they frequently consume inadequate diets. Schools
need to provide adequate and applicable health education and
prevention programs to guide adolescents to healthy choices.
Children
who eat well, learn well, according to Storey et al, authors of a
study in 2008 in which 12 schools in England
received a tailored action plan and support to modify their food
provision and dining environment over a 15-week period. Storey et al
observed behaviors during post-lunchtime classes at all schools to
investigate if there was evidence that food insufficiency
was positively associated with poorer academic, cognitive and
psychosocial development in children and young people even in the
developed world
(33).
The
study provides
evidence of the benefits on learning-related behaviors of modifying
children’s school food and eating environments.
(Storey et al 37). Storey et al found on-task
behavior had
increased and off-task behavior had decreased in both groups, but the
changes were significantly greater in the intervention group
(35). The
study showed that modifying food provision and dining environments
had the potential to improve learning-related behaviors of secondary
school pupils in the post-lunch period.
(Storey et al 35)
The
research uncovered the following effects:
improving food choices; reducing queuing times; improving the dining
ambience; and increasing time available for physical and social
activities.
(Storey et al 35) The benefits included increased
concentration and engagement can potentially improve learning
outcomes and attainment. Behavior improved during the post-lunch
period, a time in the school day that, traditionally, has been
problematic for effective classroom management
(Storey et al 36).
From
analyses based on data from the National Health and Nutrition
Examination Survey (NHANES), a complex, multistage probability sample
of the US civilian, non-institutionalized population, Ogden et al
found the prevalence of high BMI in childhood has remained steady for
10 years and has not declined (Ogden
et al 248). With adequate curriculum and instruction, educators can
help reverse this trend by teaching students how to read a nutrition
label and make healthy eating choices, which minimize their waistline
while maximizing their mental potential.
