The rate of Latinx migration to the U.S. has risen rapidly over the last several decades. Recognizing that Latinx migrant youth are exposed to a high rate of adverse events and that sleep has potential buffering effects on mental health, the current study aimed to examine sleep duration as a moderator of the link between childhood adversity and emotional and behavioral symptoms among Latinx migrant youth. One hundred and twelve first-generation migrants of Latinx ethnicity (and 46 caregivers) participated in this study; the average age was 19 (SD = 2). Participants self-reported demographics: 59.8% of participants were male, with the racial breakdown as follows: 38.8% white, 6.1% black, 4.1% mixed race, and 51% marked “other.” Data were collected from a public high school for immigrant youth in the Southwestern U.S. and included average sleep duration, Adverse Childhood Experiences; the Child PTSD Symptoms Scale and the Child Behavior Checklist. Findings indicated experiences of neglect in childhood were associated with youth-reported mental health symptoms, but this relation was significantly moderated by sleep duration such that the relation was weakened in the presence of high sleep duration. Both effects were statistically significant and of medium size. Caregiver reports supported the buffering effects of sleep; medium or large interactions between sleep and all three adversity variables (abuse, neglect, and household dysfunction) were noted in multivariate analyses. The current study takes an important first step in identifying that short sleep duration is prevalent among Central American immigrant youth. Findings suggest that sleep duration has important public health potential as a means of buffering the effects of childhood adversity on mental health in a vulnerable group.

在过去的几十年里，拉丁裔移民到美国的速度迅速上升。认识到拉丁裔移民青年遭受不良事件的几率很高，并且睡眠对心理健康具有潜在的缓冲作用，目前的研究旨在检查睡眠时间作为拉丁裔移民童年逆境与情绪和行为症状之间联系的调节因素青年。112 名第一代拉丁裔移民（和 46 名看护者）参与了这项研究；平均年龄为 19 ( SD= 2). 参与者自我报告的人口统计数据：59.8% 的参与者为男性，种族细分如下：38.8% 白人、6.1% 黑人、4.1% 混血儿和 51% 标记为“其他”。数据是从美国西南部一所面向移民青年的公立高中收集的，包括平均睡眠时间、不良童年经历；儿童 PTSD 症状量表和儿童行为清单。研究结果表明，童年时期的忽视经历与青少年报告的心理健康症状有关，但这种关系因睡眠时间而显着缓和，因此这种关系在睡眠时间长的情况下减弱。两种效应均具有统计学显着性且中等大小。看护者的报告支持睡眠的缓冲作用；在多变量分析中注意到睡眠与所有三个逆境变量（虐待、忽视和家庭功能障碍）之间存在中等或较大的相互作用。目前的研究迈出了重要的第一步，确定了中美洲移民青年普遍存在睡眠时间短的问题。研究结果表明，睡眠时间具有重要的公共卫生潜力，可以作为缓冲童年逆境对弱势群体心理健康影响的一种手段。
