description Short sleep duration has been shown to associate with increased risk of obesity. Childhood obesity is more prevalent among underserved minority children. The study measured the sleep duration of underserved minority children living in a large US urban environment using accelerometry and its relationship with BMI, socioeconomic status (SES), gender, ethnicity and physical activity. Time spent on sleep and physical activity among 333 Hispanic and 150 black children (9-12 y) was measured objectively by accelerometry over 5-7 consecutive days. The children were recruited at 14 underserved community centers in Houston, Texas, between January 2009 and February 2011. Body weight and height were measured in duplicate. The majority of children (88.8%) wore the monitor for 6 consecutive days. The children slept 8.8 ± 0.6 (mean ± SD) h/d and spent 45 ± 24 min/d on moderate-vigorous physical activity (MVPA). Hispanic children slept 0.2 h/d longer (P

There was a significant interaction between gender and age (P&lt;0.03); girls aged 11-12 y slept 0.3 h/d less than boys and the younger girls. Children slept 0.6 h/d longer (P&lt;0.001) during the weekend than weekdays. No relation was detected between sleep duration and MVPA time.
