June 16, 2011 -- Two new reports provide a snapshot of the physical activity and beverage habits of U.S. high school students. About one in 10 high school students gets the recommended amount of aerobic and muscle-strengthening exercise, and nearly a quarter of students drink at least one sugary soda every day.
Both reports, which appear in the CDC's Morbidity and Mortality Weekly Report, analyzed data from the 2010 National Youth Physical Activity and Nutrition Study that looks at the height/weight, diet, and exercise habits of high school students.
In the physical activity study, 12.2% of high school students met the Healthy People 2020 objective for aerobic and muscle-strengthening physical activity, which calls for 60 or more minutes of aerobic activity every day and some muscle strengthening on three or more days per week. Healthy People 2020 sets 10-year national goals for improving the health of Americans.
More high schoolers met the muscle-strengthening objective than the aerobic activity objective, the study showed. Specifically, 15.3% of high school students met the aerobic activity objective. Healthy People 2020 aims for this number to reach 20.2%. Fifty-one percent met the goal for muscle-strengthening activity. The specific target for muscle-strengthening activity is not yet available.
The students at greatest risk for inactivity were female, obese, and upper classmen, the study showed.
“Continued efforts through multi-sectoral approaches involving schools, communities, and health care are needed to increase youth physical activity participation,” study author MinKyoung Song, PhD, of the CDC’s division of Nutrition, Physical Activity, and Obesity, says in an email. “For example, making our communities more physical activity-friendly by providing sidewalks/bike trails so kids can walk/bike to school or providing easier access to recreational facilities or places for physical activity will be helpful.”
Soda Intake Too High
In the beverage study, 72.4% of high school students reported drinking at least one serving of water each day in the week before the survey, 42% had one or more glasses of milk, and 30.2% drank at least one serving of 100% fruit juice every day.
