Obesity reduction. In a 2014 study published in the American Journal of Preventive Medicine, researchers analyzed obesity prevention strategies and their ability to reduce obesity by the year 2032. They found afterschool physical activity programs would reduce obesity the most, 1.8% among children ages 6 to 12. That's twice the projected impact as any ban on child-directed fast-food advertising. An earlier study of college students found that "motives for sport participation are more desirable than those for exercise and may facilitate improved adherence to physical activity recommendations" (Kilpatrick, Journal of American College Health, 2005).
But the obesity epidemic continues. In 2018, a study published by the American Academy of Pediatrics showed overweight and obesity rates increased in all age groups among children ages 2 to 19 (Prevalence of Obesity and Severe Obesity in U.S. Children, 1999-2016). The rates generally increased with age, with 41.5% of teens being obese by 16 to 19 years old. Of particular concern were continued racial and ethnic disparities. White and Asian children showed significantly lower rates of obesity than Hispanic and African-American children. Researchers also found a sharp increase in obesity from 2015 to 2016 compared to the previous cycle among children ages 2 to 5, especially boys. Girls 16 to 19 years old had a notable jump in overweight rates, from 36% in 2013-14 to 48% in 2015-16. Youth who have disabilities are 4.5 times less active and have obesity rates that are 38% higher than other youth (Physical Literacy in the United States: A Model, Strategic Plan, and Call to Action, 2015).
