more than one out of eight children considered overweight, childhood obesity
is a national epidemic. Because of this, Elena Serrano and Ruby Cox in
Virginia Tech's Department of Human Nutrition, Foods, and Exercise have
not only been leading research projects to understand the problem, especially
among youth in Virginia, but also are leading efforts to do something
Excessive weight in children represents a major health concern — both
physically and emotionally. The risk factors associated with diseases
linked to overweight and obese adults can be tracked from childhood. Medical
reports show increasing rates of Type 2 diabetes, a potentially debilitating
disease. This increase is attributed to the growing rate of overweight
individuals. Youngsters also suffer from the damaging social and psychological
effects of being overweight in a society that stresses thinness and may
even discriminate against large-sized individuals. For children, this
problem is amplified. According to the researchers, large children report
feeling isolated and lonely more than children who are not overweight.
These youngsters indicated they are preoccupied with body image, lack
self-confidence, have lower self-concept, and may also feel depressed
and rejected by friends.
The problem may be especially evident in the South, where the percentage
of overweight people exceeds the national average in all states except
Florida. Additionally, of the five cities across the country with the
highest obesity rates, three are located in the South: Charleston, W.Va.;
San Antonio, Texas; and Jackson, Miss.
To learn the status of Virginia youngsters, Serrano and Cox collected
weight and height data from five ethnically diverse and limited-resource
elementary and middle schools in rural and urban areas ("limited
resource" refers to schools where many students qualify for reduced-price
or free lunches). Serrano and Cox found that nearly one-quarter of fourth
and fifth graders in the study were overweight. Funded by the Southern
Rural Development Center, the two researchers also looked at differences
based on location and ethnicity. Their data indicated that white, rural
children were significantly heavier and had larger waist circumferences
than those in urban areas. Conversely, Latino and black children in urban
areas were significantly heavier than those in rural areas. Age, gender,
or school didn't seem to make any difference in being overweight.
"While we see some interesting trends in our data, the problem is
clearly complex and has not only food, nutrition, and physical activity
elements, but public policy issues as well," says Serrano.
She and Cox reviewed information from other researchers studying the
concerns of overweight and found several contributing factors. More people
are eating out. Many experts have reported that restaurant portion size
has increased and that eating away from home is linked to higher caloric
and fat intakes. Consumption of fast food by children increased five-fold
between the 1970s and mid-1990s. And children who eat fast food consume
more calories, total fat, and added sugars; less fiber and milk; and fewer
fruits and vegetables than children who do not eat fast food.
part of the concern is lack of physical activity. Nationally, almost two-thirds
of children ages nine to 13 years do not participate in organized physical
activities outside of school and almost one-quarter do not engage in any
free-time physical activity. In 1998, children were reported to view an
average of 3.6 hours of television per day.
Serrano also noted that many schools are facing pressure to eliminate
physical education programs to save money and to have more time for core
subject areas in order to meet state Standards of Learning. Typically,
physical education classes are much larger than core subject classes,
making it difficult and challenging to offer individualized attention
to youth and to promote quality physical education. Many youngsters no
longer walk to school because of safety concerns. In some neighborhoods,
families feel it's not safe for children to ever be outside. In Virginia,
while recess is mandated, there is no minimum set time, so the periods
vary from school to school. Some schools in other states have eliminated
Serrano and Cox are in positions in Virginia Tech's College of Agriculture
and Life Sciences to use the research findings to help Virginia citizens.
Serrano co-chairs Virginia Action for Healthy Kids, along with the first
lady of Virginia, along with the first lady of Virginia, actionforhealthykids/
Lisa Collis, and Cathleen Grzesiek of the Virginia Council of the American
Heart Association. The coalition is committed to improving the health
of Virginia's youth by working to ensure that healthy snacks and foods
are provided in vending machines, school stores, and other venues within
the schools' control, and to promote quality physical activity during
and after school, including in core subjects.
"We represent many organizations in Virginia Action for Healthy
Kids and work with several schools and school districts," to help
schools create healthy environments for students, says Serrano. The coalition
has created best practices awards to recognize schools that have made
efforts to improve nutrition and physical activity in schools and a resource
guide of curricula in line with the Standards of Learning. The coalition
is developing a toolkit to help schools make changes and resources to
aid classroom teachers in incorporating physical activity into all classes.
The Virginia Action for Healthy Kids sent what it calls "nutrition
integrity" recommendations to all the school superintendents in Virginia
in 2003, Serrano says. The recommendations include replacing foods considered
of "minimal nutritional value" with healthier snack items in
vending machines. Examples include offering water, 100 percent juice,
and low-fat milk in place of soda and fruit beverages, and keeping portion
sizes of snacks offered in vending machines to less than 300 calories
Serrano and Cox's studies of the five schools have provided a basis for
these recommendations. For example, Serrano says, "An interesting
finding was the relationship between self-reported grades, breakfast,
and several other healthy behaviors. With the increasing pressure on schools
to perform well on standardized tests, one solution may be to encourage
principals and school officials to offer breakfast at school as part of
the U.S. Department of Agriculture school breakfast program, and to ensure
that foods offered in the school environment help promote healthy eating
and, therefore, achievement."
Another way Virginia Tech is helping families with children avoid obesity
is the program headed by Cox. She is coordinator of the Virginia Expanded
Food and Nutrition Education Program (EFNEP) and the Smart Choices Nutrition
Education Program (SCNEP). These federal programs bring food and nutrition
education directly to families. Virginia Cooperative Extension agents
provide education for program assistants who then lead programs in their
own neighborhoods. It is aimed at helping limited-resource families make
the most of their money for food and it has a 4-H youth development component
to reach youngsters directly to teach them about healthy eating.
Training the program assistants to teach children helps the youngsters
avoid becoming overweight or obese, says Cox. In one lesson, EFNEP/SCNEP
assistants have the youngsters put their napkins like a placemat in front
of them and put the food on the napkins. If the food makes a greasy stain,
the child can conclude that the food probably has a lot of fat.
"It helps even very young children to know about the food they are
eating," says Cox.
Serrano developed a Healthy Weights for Healthy Kids program that encompasses
the recommendations from her and Cox's research, and the pair are implementing
the program in the EFNEP and SCNEP. Healthy Weights for Healthy Kids offers
youngsters experiential learning in nutrition, physical activity, and
body image. The EFNEP/SCNEP is in almost all the counties and independent
cities in Virginia, providing education programs for about 20,000 youngsters
and 10,000 adults annually.
