| Popis: | Objectives Sedentary behavior (SB) is distinct from physical inactivity. Children's guidelines recommend ≤ 2 h/day screen time and ≥ 60 min/day moderate-to-vigorous physical activity (MVPA). This study describes SB in children at elevated risk of obesity, including the possibility of high SB in otherwise active children. Methods Participants were 534 children from Quebec, Canada, aged 8–10 years with ≥ 1 obese parent in 2005–2008. SB and MVPA were measured by accelerometer and specific SBs by self-report, and height and weight were directly measured. Results Overweight/obese children were significantly more sedentary overall and reported higher screen time than normal weight children. About 19% of boys and 46% of girls met screen time but not PA guidelines; 28% of boys and 5% of girls met PA but not screen time guidelines. About 46% of overweight/obese children met neither guideline (32% normal weight); only 5% overweight/obese children met both (21% normal weight). Reported behaviors contributed 60%–80% of total SB time; the most sedentary children had the most unaccounted for SB time. Conclusions Overweight/obese children are more sedentary overall and report higher screen time than normal weight children. Public health efforts targeting PA and SB in children must consider sex and weight status while being cognizant that being sufficiently active is not exclusive of high levels of SB. |
