The Facts about Overweight and Obesity
among Our
Children and Teens
Findings from the Centers for Disease Control & Prevention
America loves to think of itself as a youthful nation focused
on fitness. But behind the vivid media images of robust runners,
Olympic Dream Teams, and rugged mountain bikers is the troubling
reality of a generation of young people that is, in large
measure, inactive, unfit, and increasingly overweight.
The consequences of the sedentary lifestyles lived by so many
of our young people are grave. In the long run, physical inactivity
threatens to reverse the decades-long progress we have made
in reducing death and suffering from cardiovascular diseases.
A physically inactive population is at increased risk for
many chronic diseases, including heart disease, stroke, colon
cancer, diabetes, and osteoporosis. In addition to the toll
taken by human suffering, surges in the prevalence of these
diseases could lead to crippling increases in our national
health care expenditures.
The landmark 1996 Surgeon General’s report, Physical
Activity and Health, identified substantial health benefits
of regular participation in physical activity:
Regular participation in physical activity during childhood
and adolescence:
Helps build and maintain healthy bones, muscles, and joints.
Helps control weight, build lean muscle, and reduce fat.
Prevents or delays the development of high blood pressure
and helps reduce blood pressure in some adolescents with hypertension.
Reduces feelings of depression and anxiety.
Through its effects on mental health, physical activity may
help increase students’ capacity for learning.
The Surgeon General made the following recommendations
for young people: All adolescents should be physically active
daily, or nearly every day, as part of play, games, sports,
work, transportation, recreation, physical education, or planned
exercise, in the context of family, school, and community
activities. Adolescents should engage in three or more sessions
per week of activities that last 20 minutes or more at a time
and that require moderate to vigorous levels of exertion.
