This study evaluated the influence of child and family functioning on child sleep behaviors in low-income minority families who are at risk for obesity. A cross-sectional study was utilized to measure child and family functioning from 2013 to 2014. Participants were recruited from Head Start classrooms while data were collected during home visits. A convenience sample of 72 low-income Hispanic (65%) and African American (32%) families of preschool-aged children were recruited for this study. We assessed the association of child and family functioning with child sleep behaviors using a multivariate multiple linear regression model. Bootstrap mediation analyses examined the effects of family chaos between child functioning and child sleep problems. Poorer child emotional and behavioral functioning related to total sleep behavior problems. Chaos associated with bedtime resistance significantly mediated the relationship between Behavioral and Emotional Screening System (BESS) and Bedtime Resistance. Families at high risk for obesity showed children with poorer emotional and behavioral functioning were at higher risk for problematic sleep behaviors, although we found no link between obesity and child sleep. Family chaos appears to play a significant role in understanding part of these relationships. Future longitudinal studies are necessary to establish causal relationships between child and family functioning and sleep problems to further guide obesity interventions aimed at improving child sleep routines and increasing sleep duration.
本研究评估了儿童及家庭功能对有肥胖风险的低收入少数族裔家庭中儿童睡眠行为的影响。2013年至2014年采用横断面研究来测量儿童及家庭功能。参与者从“启智计划”教室招募，数据在家庭访视期间收集。本研究招募了72个低收入西班牙裔（65%）和非裔美国人（32%）的学龄前儿童家庭组成的便利样本。我们使用多元多重线性回归模型评估儿童及家庭功能与儿童睡眠行为之间的关联。自抽样中介分析检验了家庭混乱在儿童功能与儿童睡眠问题之间的作用。较差的儿童情绪和行为功能与总的睡眠行为问题相关。与就寝抵抗相关的混乱显著中介了行为与情绪筛查系统（BESS）和就寝抵抗之间的关系。肥胖高风险家庭中，情绪和行为功能较差的儿童出现问题睡眠行为的风险更高，尽管我们未发现肥胖与儿童睡眠之间存在关联。家庭混乱似乎在理解这些关系的部分方面发挥了重要作用。未来有必要进行纵向研究，以确立儿童及家庭功能与睡眠问题之间的因果关系，从而进一步指导旨在改善儿童睡眠习惯和增加睡眠时间的肥胖干预措施。
