项目摘要

Children from racial minority and low socioeconomic (SES) households are at greatest risk for overweight and obesity (OWOB) and sleep is a risk factor. Although most research linking sleep and OWOB has focused on sleep duration, emerging evidence indicates that additional aspects of sleep (i.e., day-to-day variability in sleep) are independently associated with greater adiposity, poor emotional regulation, and lower quality of life in children. Sleep variability is not well understood in children due to cross-sectional study design, and parent- or self-reported sleep data. Current research is only beginning to examine the multifaceted nature of sleep, but a better understanding of sleep variability through longitudinal designs is needed to identify health implications. Further, the home environment is a major contributor to children’s sleep, yet few studies have examined the this beyond a single facet (i.e., bedtime routines). Home disorganization (e.g., chaos, noise) is associated with poor physical and mental health. Children from low SES families may be more likely to experience home disorganization compared to peers from high SES families. Of the studies examining the relationship between home environment and sleep in elementary school-age children, many included predominately white, affluent samples. One of these studies sampled children from low SES households and used an objective measure of sleep. Understanding home disorganization and its relationship to sleep, beyond duration, among children from minority and low SES households holds promise for identifying salient intervention targets to improve sleep, which can lead to improved weight status and reduce health disparities. This project leverages data collected from a longitudinal cohort (N = 504) of 1st - 3rd grade children from low and high SES households, with a 50% African American sample (NIDDK:R01DK116665) and a RCT (N = 140) of 1st - 3rd grade children from low SES households (NIDDK:R01DK120490) randomized to attend summer camp. Home disorganization is assessed via questionnaires and daily diaries for 14 days during the school year and summer. Simultaneously, children’s sleep is objectively assessed with wrist-based accelerometry. The primary aim will determine the moderating effects of SES and race/ethnicity in the association between home disorganization and sleep variability. The secondary aim will identify differences in home disorganization between the school year and summer, and their relationship with sleep variability. The home environment and intraindividual sleep variability are emerging factors associated with the risk of OWOB yet are understudied components of children’s obesogenic behaviors. This study is significant as greater understanding of home environment and insight into potential intervention targets will be possible. This study is innovative as it utilizes a longitudinal and RCT design, employs an objective measure of sleep, and assesses home disorganization and sleep variability prospectively. Findings will advance our understanding of the influence of home disorganization on sleep beyond commonly assessed average duration.
来自少数民族和低社会经济地位家庭的儿童超重和肥胖的风险最大, 肥胖(OWOB)和睡眠是危险因素。尽管大多数关于睡眠和OWOB的研究都集中在 睡眠持续时间,新出现的证据表明睡眠的其他方面(即,睡眠的日间变化) 与肥胖、情绪调节不良和生活质量下降独立相关。 孩子由于横断面研究设计,儿童的睡眠变异性还没有得到很好的理解, 自我报告的睡眠数据。目前的研究只是开始研究睡眠的多方面性质,但 需要通过纵向设计更好地理解睡眠可变性,以确定健康影响。 此外,家庭环境是儿童睡眠的主要因素,但很少有研究对此进行研究。 除了单个刻面(即,睡前常规)。家庭混乱(例如,混乱,噪音)与穷人有关 身心健康。来自低社会经济地位家庭的孩子可能更有可能体验到家庭生活 与来自高社会经济地位家庭的同龄人相比,在这些研究中, 家庭环境和睡眠在小学学龄儿童中,许多人主要包括白色,富裕 样品其中一项研究对来自低社会经济地位家庭的儿童进行了抽样调查, 睡吧了解家庭混乱及其与睡眠的关系,超过持续时间,在儿童中, 少数民族和低社会经济地位家庭有希望确定突出的干预目标,以改善睡眠, 这可以改善体重状况,减少健康差距。该项目利用收集的数据 来自低和高SES家庭的1 - 3年级儿童的纵向队列(N = 504),50% 非裔美国人样本(NIDDK:R 01 DK 116665)和来自低SES的1 - 3年级儿童的RCT(N = 140) 家庭(NIDDK:R 01 DK 120490)随机参加夏令营。家庭解体评估通过 在学年和夏季的14天里,调查问卷和每日日记。与此同时,儿童的睡眠 是通过腕部加速度计进行客观评估的主要目标将决定调节效应 SES和种族/民族在家庭混乱和睡眠变异性之间的关联。次级 aim将确定学年和夏季之间家庭混乱的差异,以及它们之间的关系 睡眠的可变性。家庭环境和个体内睡眠变异性是相关的新兴因素 与OWOB的风险,但尚未充分研究的儿童肥胖行为的组成部分。本研究 重要的是,更好地了解家庭环境和了解潜在的干预目标, 可能这项研究是创新的,因为它采用了纵向和RCT设计,采用了客观的衡量标准, 睡眠,并前瞻性地评估家庭混乱和睡眠变异性。这些发现将推动我们 了解家庭混乱对睡眠的影响超出通常评估的平均持续时间。
