To describe sleep duration, adherence to sleep recommendations, and behavioral and sociodemographic correlates of sleep among Samoan children.
In a longitudinal cohort study of Samoan children aged 2-9years (n = 481; 50% female), primary caregivers reported usual number of hours of nighttime sleep during 2015, 2017/2018, and 2019/2020 data collection waves. Associations between behavioral and sociodemographic characteristics and sleep duration were assessed using generalized linear and mixed effect regressions.
Average reported hours of nighttime sleep for toddlers (age 2) was 9.7 ± 1.1 (SD); for preschoolers (age 3-5) 9.5 ± 1.0, and for school-age children (age 6-9) 9.4 ± 1.3, with 58% of children meeting sleep recommendations. Living in a lower income household was associated with 30 more minutes of sleep for toddlers (adjusted β:0.56 [95% CI: 0.03, 1.09]) and preschoolers (adjusted β:0.51 [95% CI: 0.17, 0.85]), while higher reported physical activity was associated with longer sleep for school-age children (adjusted β:0.49 [95% CI: 0.08, 0.91]). Preschoolers with a primary caregiver who did not complete high school had shorter sleep (β: -0.80 [95% CI: -1.12, -0.48]). Among school-aged children, shorter sleep was associated with greater total carbohydrate intake (for every 100 g/day, β: -0.01 [95% CI: -0.02, 0.01]) and neotraditional dietary pattern adherence (β: -0.27 [95% CI: -0.53, -0.01]).
Efforts should be made to encourage adequate sleep among Samoan children. Correlates of sleep were largely consistent with existing literature. Future research should examine additional culturally and contextually-specific risk factors for insufficient sleep in Samoa and consequences for child health.
描述萨摩亚儿童的睡眠时间、对睡眠建议的遵守情况以及睡眠的行为和社会人口学相关因素。
在一项对2至9岁萨摩亚儿童（n = 481；50%为女性）的纵向队列研究中，主要照顾者报告了2015年、2017/2018年和2019/2020年数据收集期间夜间睡眠的通常小时数。使用广义线性和混合效应回归评估行为和社会人口学特征与睡眠时间之间的关联。
幼儿（2岁）报告的平均夜间睡眠时间为9.7±1.1（标准差）；学龄前儿童（3至5岁）为9.5±1.0，学龄儿童（6至9岁）为9.4±1.3，58%的儿童符合睡眠建议。生活在低收入家庭中，幼儿（调整后的β：0.56 [95%置信区间：0.03, 1.09]）和学龄前儿童（调整后的β：0.51 [95%置信区间：0.17, 0.85]）的睡眠时间会多30分钟，而报告的体育活动量较高与学龄儿童睡眠时间较长相关（调整后的β：0.49 [95%置信区间：0.08, 0.91]）。主要照顾者未完成高中学业的学龄前儿童睡眠时间较短（β：-0.80 [95%置信区间：-1.12, -0.48]）。在学龄儿童中，睡眠时间较短与碳水化合物总摄入量较高（每100克/天，β：-0.01 [95%置信区间：-0.02, 0.01]）和遵循新传统饮食模式相关（β：-0.27 [95%置信区间：-0.53, -0.01]）。
应努力鼓励萨摩亚儿童获得充足睡眠。睡眠的相关因素在很大程度上与现有文献一致。未来的研究应探讨萨摩亚其他文化和背景特定的睡眠不足风险因素以及对儿童健康的影响。
