Physical activity is a key component of many obesity prevention strategies. The aim of this analysis was to identify child, family, and household characteristics associated with parent-reported physical activity in Samoan children aged 3-8 years. Children (n = 445; 51.2% female, mean age 5.4 years) were part of an ongoing, mixed-longitudinal study of child growth, development, and wellbeing (the Ola Tuputupua'e cohort). Bivariate analyses and multivariate generalized linear regressions were conducted to investigate the relationship of child, family, and household characteristics with physical activity level, measured using the Netherlands Physical Activity Questionnaire (NPAQ). Children were classified as being 'highly active' if they had NPAQ scores in the 75th percentile or above. Among the n = 111 children classified as 'highly active', n = 67 (60.4%) were boys. After adjusting for child, family, and household-level characteristics, hours of child sleep per night was the only variable significantly associated with odds of being highly active. Compared to children who slept less than 9 hours at night, those who slept 10-10.99 hours (OR: 5.97, 95% CI: 2.14-18.13) and 11+ hours (OR: 25.75, 95% CI: 8.14-90.12) had higher odds of being 'highly active'. Future research should examine the mechanisms driving the relationship between nighttime sleep and physical activity among Samoan children. Intervening on sleep duration and quality may improve physical activity and, in turn, obesity risk in this setting.
体育活动是许多肥胖预防策略的关键组成部分。本分析的目的是确定与萨摩亚3至8岁儿童家长报告的体育活动相关的儿童、家庭和家庭特征。儿童（n = 445；51.2%为女性，平均年龄5.4岁）是一项正在进行的关于儿童生长、发育和健康的混合纵向研究（奥拉·图普图普阿埃队列）的一部分。进行了双变量分析和多变量广义线性回归，以研究儿童、家庭和家庭特征与使用荷兰体育活动问卷（NPAQ）测量的体育活动水平之间的关系。如果儿童的NPAQ得分在第75百分位或以上，则被归类为“高度活跃”。在n = 111名被归类为“高度活跃”的儿童中，n = 67名（60.4%）为男孩。在调整了儿童、家庭和家庭层面的特征后，每晚儿童睡眠时间是与高度活跃几率显著相关的唯一变量。与晚上睡眠时间少于9小时的儿童相比，睡眠时间为10 - 10.99小时（OR：5.97，95% CI：2.14 - 18.13）和11小时以上（OR：25.75，95% CI：8.14 - 90.12）的儿童“高度活跃”的几率更高。未来的研究应探讨驱动萨摩亚儿童夜间睡眠与体育活动之间关系的机制。干预睡眠时间和质量可能会改善体育活动，进而降低该环境下的肥胖风险。
