Underserved minority children are not meeting the moderate‐to‐vigorous physical activity (MVPA) recommendation

Childhood obesity is more prevalent among underserved minority children. It is recommended that children should spend a minimal of 60 min/d in MVPA in order to maintain a healthy body weight. Based on a minimal of 5 days of Actical measurements, we quantified the amount of MVPA in 483 underserved minority children (10.3±1.0 y; 51.1% male; 31.1% Black/68.9% Hispanic; 66% overweight or obese) who took part in our community childhood obesity intervention program (Healthy Kids‐Houston). The majority of children (89.4%) were in the reduced cost/free meal program and 71.1% had no health insurance or were insured under programs for low‐income families. The children spent more time on MVPA (p<0.01) on weekdays (46.8±1.2 min/d, mean±SE) than on weekend days (41.0±1.6 min/d). Time spent on MVPA decreased with age (−5 min/d per y, p< 0.01) with boys spending more time (12.6 min/d, p<0.01) in MVPA than girls. Black children also spent more time on MVPA (6 min/d, p=0.03) than Hispanic children. MVPA also decreased with BMI z‐score (p<0.01). Most alarmingly, the majority of children (76.4%) spent less than 60 min/d on MVPA. Therefore, to combat childhood obesity, public and private resources should be invested to promote MVPA and to enhance the environment for underserved, minority children.
