We investigated associations between family income-to-needs, nighttime bedroom temperature (NBT), and children's sleep. Using a sample of 46 children ( = 11.5), we recorded NBT and objective sleep parameters via actigraphy nightly for one week to evaluate within- (night-to-night) and between-person associations. We found consistent evidence for a curvilinear association between NBT and sleep variables at the between-person level, indicating that children who slept in rooms that were "too hot" or "too cold" experienced poorer sleep. Moreover, children in lower income-to-needs families had more extreme NBTs. There was some evidence that family income-to-needs is indirectly related to sleep via NBT, but with interpretational caveats. These findings point to NBT as a potentially modifiable variable, which has implications for practical applications to mitigate effects of socioeconomic disparities on children's sleep.
我们研究了家庭收入需求比、夜间卧室温度（NBT）和儿童睡眠之间的关联。我们以46名儿童（平均年龄 = 11.5岁）为样本，通过活动记录仪每晚记录NBT和客观睡眠参数，为期一周，以评估个体内部（夜与夜之间）以及个体之间的关联。我们发现有一致的证据表明，在个体之间的层面上，NBT与睡眠变量之间存在曲线关联，这表明睡在“过热”或“过冷”房间里的儿童睡眠质量较差。此外，收入需求比低的家庭中的儿童夜间卧室温度变化更大。有证据表明，家庭收入需求比通过夜间卧室温度与睡眠存在间接关联，但需注意解释的局限性。这些发现表明夜间卧室温度是一个潜在的可调节变量，这对于减轻社会经济差异对儿童睡眠的影响的实际应用具有重要意义。
