This study examines associations between internalizing symptoms and sleep in a sample of urban children with and without asthma, whether asthma status moderates these associations, and whether associations differ by ethnic group.
Participants were Latino, African American (AA), and non-Latino white (NLW) urban 7- to 9-year-olds with (n = 259) and without (n = 122) persistent asthma. Teacher-reported internalizing symptoms (anxiety, depressive, and somatic) were assessed using the Behavioral Assessment System for Children-2. Sleep duration, variability in sleep duration, and sleep onset latency were assessed with actigraphy.
Depressive symptoms were associated with variability in sleep duration and shorter sleep onset latency; somatic symptoms were associated with variability in sleep duration. In Latino children, depressive symptoms were associated with shorter sleep onset latency. In AA children, anxiety, depressive, and somatic symptoms were associated with variability in sleep duration; somatic symptoms were related to variability in sleep duration in NLW children. The association between internalizing symptoms and sleep outcomes did not differ by asthma status. However, asthma status was a significant moderator when examining these associations by ethnic group: among AA children, depressive symptoms were significantly related to variability in sleep duration only in children with asthma, whereas in NLW children, somatic symptoms were related to variability in sleep duration only in children without asthma.
Targeting specific internalizing symptoms and sleep outcomes may be beneficial in the development of interventions tailored for urban children with and without asthma from specific ethnic groups.
本研究调查了有和没有哮喘的城市儿童样本中内化症状与睡眠之间的关联，哮喘状况是否调节这些关联，以及这些关联是否因种族而异。
参与者为7至9岁的城市儿童，包括拉丁裔、非裔美国人（AA）和非拉丁裔白人（NLW），其中有持续性哮喘的儿童259名，无持续性哮喘的儿童122名。使用儿童行为评估系统-2评估教师报告的内化症状（焦虑、抑郁和躯体症状）。通过活动记录仪评估睡眠时间、睡眠时间变异性和入睡潜伏期。
抑郁症状与睡眠时间变异性和较短的入睡潜伏期相关；躯体症状与睡眠时间变异性相关。在拉丁裔儿童中，抑郁症状与较短的入睡潜伏期相关。在非裔美国儿童中，焦虑、抑郁和躯体症状与睡眠时间变异性相关；在非拉丁裔白人儿童中，躯体症状与睡眠时间变异性相关。内化症状与睡眠结果之间的关联不因哮喘状况而异。然而，在按种族检查这些关联时，哮喘状况是一个显著的调节因素：在非裔美国儿童中，抑郁症状仅在患有哮喘的儿童中与睡眠时间变异性显著相关，而在非拉丁裔白人儿童中，躯体症状仅在没有哮喘的儿童中与睡眠时间变异性相关。
针对特定的内化症状和睡眠结果可能有助于为来自特定种族的有和没有哮喘的城市儿童制定量身定制的干预措施。
