PROJECT SUMMARY/ABSTRACT By the age of 3 years, Latino children are disproportionately affected by deficient sleep (short sleep duration, poorly timed sleep) and obesity. However, few studies have considered predictors of deficient sleep and its relationship with the disparate prevalence of early childhood obesity, specifically in toddlers (12 to 39 months) from Mexican American families. Because sleep is influenced by many different factors, this study will be one of the first to evaluate socioecological predictors, including environmental (e.g., societal, neighborhood, household), sociocultural (e.g., acculturation, beliefs), and parental factors (e.g., sleep-related parenting practices) in this population. While the relationship between deficient sleep and obesity has been found in children and adolescents, research with toddlers is limited by a lack of long-term studies and the use of parent report of child sleep (instead of an objective measure of sleep). Further, toddlers from Mexican American families are underrepresented in this research, despite being one of the largest growing ethnic minority populations in the U.S. The proposed study will address these knowledge gaps, answering critical questions about how different factors impact toddler sleep, and in turn whether toddler sleep contributes to the disparate prevalence of obesity in toddlers from Mexican American families. We have brought together a multidisciplinary team with substantial expertise in pediatric sleep, obesity, and socioecological contributors to health behaviors to (1) identify environmental, sociocultural, and parental factors contributing to deficient sleep, and (2) determine the relationship between sleep and weight status over a 2-year period in toddlers from Mexican American families. In order to ensure culturally-relevant measurement, we will use qualitative methods (focus groups) with Mexican American parents to adapt measures of parental sleep beliefs and sleep-related parenting practices as needed. We will then enroll 380 Mexican American families (mothers, fathers, other primary caregivers residing in the home) with 12 to 15 month old children living in a large metropolitan area to participate in 3 annual assessments. At each assessment, questionnaire and anthropometric data will be collected, and parent and toddler sleep will be measured by 7 consecutive days/nights of actigraphy (a wrist- watch sized device that objectively measures sleep). This innovative study will provide an in-depth evaluation of the ecology in which parent and toddler sleep are embedded, and the relationship of sleep with toddler weight status in the target population. To ensure the child’s entire family system is considered, mothers, fathers, and other primary caregivers in the home will be included. Altogether, study findings will contribute to the future development of family-focused, culturally-tailored, and contextually-informed early prevention programs focused on sleep and weight status in this underserved population. This study is a critical next step toward reducing health disparities and improving health outcomes among toddlers from Mexican American families.

项目摘要/摘要 到3岁时，拉美裔儿童受到睡眠不足的影响不成比例(睡眠时间短， 睡眠时间不佳)和肥胖。然而，很少有研究考虑睡眠不足和睡眠不足的预测因素。 与儿童早期肥胖率不同的关系，特别是在学步儿童(12至39个月) 来自墨西哥裔美国家庭。因为睡眠受到许多不同因素的影响，这项研究将是其中之一 首先评估社会生态预测因素，包括环境(例如，社会、邻里、 家庭)、社会文化(例如，文化适应、信仰)和父母因素(例如，与睡眠有关的育儿 实践)。虽然睡眠不足和肥胖之间的关系已经在 对于儿童和青少年，由于缺乏长期研究和父母的使用，对幼儿的研究受到限制 儿童睡眠报告(而不是客观的睡眠衡量标准)。此外，来自墨西哥裔美国人的学步儿童 在这项研究中，尽管家庭是最大的增长中的少数民族之一，但家庭的代表性不足 这项拟议的研究将解决这些知识差距，回答关键问题 关于不同因素如何影响蹒跚学步的孩子的睡眠，反过来，蹒跚学步的孩子的睡眠是否对不同的 墨西哥裔美国家庭学步儿童的肥胖率。我们汇集了一个多学科的 在儿科睡眠、肥胖和健康行为的社会生态贡献者方面拥有丰富专业知识的团队 (1)确定导致睡眠不足的环境、社会文化和父母因素，以及(2) 确定墨西哥学步儿童两年内睡眠和体重状况之间的关系 美国家庭。为了确保与文化相关的测量，我们将使用定性方法(焦点 小组)与墨西哥裔美国父母一起调整父母的睡眠信念和睡眠相关指标 根据需要进行育儿实践。然后我们将招收380个墨西哥裔美国家庭(母亲、父亲、其他 居住在家里的主要照顾者)与居住在大城市地区的12至15个月大的孩子一起 参加3次年度评估。在每次评估中，调查问卷和人体测量数据将 收集，父母和幼儿的睡眠将通过连续7个昼夜的活动(手腕- 观看大小客观测量睡眠的设备)。这项创新的研究将提供深入的评估 关于父母和幼儿睡眠的生态，以及睡眠与幼儿的关系 目标人群中的体重状况。为了确保孩子的整个家庭系统得到考虑，母亲们， 父亲和家中的其他主要照顾者将被包括在内。总之，研究结果将有助于 以家庭为中心、根据文化量身定做和根据背景情况进行的早期预防的未来发展 项目重点关注这一服务不足人群的睡眠和体重状况。这项研究是关键的下一步 减少墨西哥裔美国儿童的健康差距和改善健康状况 家人。
