Disparities in moderate-to-vigorous physical activity among girls and overweight and obese schoolchildren during school- and out-of-school time
In a study measuring the physical activity of 453 schoolchildren in Massachusetts, only 15 percent of students achieved the CDC-recommended 60 minutes of daily MVPA throughout the day, and only 8 percent met the recommendation of 30 minutes of MVPA during school. The greatest disparity was between boys and girls, with girls being far less likely than boys to meet both of these guidelines.
