Short sleep is consistently linked with childhood obesity, possibly via disrupting appetite hormones and increasing food responsiveness. Few studies have objectively examined this association in early childhood. To evaluate associations of sleep quantity and quality with child appetitive traits and eating in the absence of hunger (EAH) in a higher-income cohort of 86 preschool-age children (age 4.0 ± 0.8 years; 42% female; 93% non-Hispanic white, Northern New England, US). Children’s sleep duration and quality were assessed via parent report (Children’s Sleep Habits Questionnaire, CSHQ) at baseline and 6-month follow-up and via accelerometry at baseline. Parents also completed the Child Eating Behaviors Questionnaire to assess the child’s appetitive traits. EAH, an objective measure of overeating, was observed at baseline during an in-person visit. Associations between sleep measures and appetitive traits were examined with linear mixed-effect or linear regression models, as appropriate, adjusting for child age, sex, and household income. Shorter sleep duration per parent report was associated with less satiety responsiveness (standardized ß = 0.14, 95% CI: 0.01, 0.26; = 0.03). Further, satiety responsiveness was inversely related to EAH (Pearson’s = -0.35, = 0.02). No associations were found between accelerometer-measured sleep parameters and appetitive traits, and no sleep measures were related to EAH. Shorter usual sleep, per the parent report, was cross-sectionally associated with reduced satiety responsiveness in this sample of higher-income preschoolers. Future studies should consider whether socioeconomic status may modify the impact of poor sleep on appetitive traits in early childhood

高收入学龄前儿童睡眠与食欲特征之间的关联：一项为期六个月的研究。


睡眠不足一直与儿童肥胖有关，可能是通过扰乱食欲激素和增加食物反应性来实现的。很少有研究客观地检验幼儿期的这种关联。旨在评估 86 名学龄前儿童（年龄 4.0 ± 0.8 岁；42% 为女性；93% 非西班牙裔）的高收入队列中睡眠数量和质量与儿童食欲特征和无饥饿饮食 (EAH) 的关系白色，美国新英格兰北部）。儿童的睡眠持续时间和质量通过基线时的家长报告（儿童睡眠习惯问卷，CSHQ）和 6 个月的随访以及基线时的加速度测量进行评估。家长还完成了儿童饮食行为调查问卷，以评估孩子的食欲特征。 EAH 是一种客观衡量暴饮暴食的指标，是在现场访问期间在基线上观察到的。通过适当的线性混合效应或线性回归模型来检查睡眠指标和食欲特征之间的关联，并根据儿童年龄、性别和家庭收入进行调整。根据家长报告，较短的睡眠时间与较低的饱腹感反应相关（标准化 ß = 0.14，95% CI：0.01，0.26；= 0.03）。此外，饱腹感反应性与 EAH 成反比（Pearson = -0.35，= 0.02）。没有发现加速计测量的睡眠参数与食欲特征之间存在关联，并且没有睡眠测量与 EAH 相关。根据家长报告，在高收入学龄前儿童样本中，通常睡眠时间较短与饱腹感反应降低有关。未来的研究应该考虑社会经济地位是否可以改变睡眠不足对幼儿期食欲特征的影响
