睡眠是最佳功能所必需的。关于种族和活动机会对全日制托儿所的学龄前儿童睡眠的影响程度，人们知之甚少。这项横断面研究的参与者(n = 359)参加了在俄亥俄州辛辛那提随机选择的30个托儿中心。数据收集发生在2009年11月至2011年1月。对夜间睡眠持续时间与种族、室外/室内活动时间、实际体力活动(PA)、屏幕时间、白天小睡和晚上9点以后的就寝时间之间的关系进行了分层线性回归和广义估计方程测试。受试者在托儿期的平均 ± SD为1.5 ± 0.8 h，睡前为9.7 ± 1.0 h。白人儿童(Beta = 0.57 ± 0.14，p
Sleep is necessary for optimal functioning. Little is known about the extent to which race and opportunities to be active influence sleep in preschool-aged children attending full-day child care. Participants (n = 359) in this cross-sectional study attended 30 randomly selected, childcare centers in Cincinnati, OH. Data collection occurred from November 2009 to January 2011. Hierarchical linear regression and generalized estimating equations tested for associations between nighttime sleep duration and race, outdoor/indoor active time, actual physical activity (PA), screen time, daytime nap, and bedtime after 9 pm. Participants slept a mean ± SD of 1.5 ± 0.8 h at childcare and 9.7 ± 1.0 h at bedtime. White children (beta = 0.57 ± 0.14, p
