Abstract

Purpose: To compare motor proficiency, strength, endurance, and physical activity among children from minority backgrounds who were healthy weight (HW), overweight (OW), or obese (OB).

Methods: Eighty-six children, aged 10 to 15 years, of mostly Hispanic ethnicity, participated. Children were categorized according to body mass index-for-age percentile. Bruininks-Oseretsky Test of Motor Proficiency (BOT2) Short Form, Sit-to-Stand (STS), Timed Up and Down Stairs, and 6-Minute Walk Test (6MWT) were administered. Physical activity was measured by using activity monitors.

Results: Forty-five percent of children were classified as OW/OB. Children who were OB had lower mean BOT2, STS, and 6MWT performance than children of HW. Among children who were OW/OB, daily mean steps were lower and sedentary minutes higher than children of HW. In children who were OW/OB, body mass index was negatively correlated with BOT2, STS, and abdominal curls.

Conclusion: Children who are OB demonstrate greater impairments in motor proficiency, strength, and endurance and participate in less physical activity than peers of HW.
