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，拉丁裔儿童受默认睡眠的影响不成比例（睡眠时间短， 时间不足的睡眠）和肥胖。但是，很少有研究考虑了睡眠不足及其的预测指标 与幼儿对象的不同患病率，特别是在幼儿中的关系（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，所以这项研究将是一个 第一个评估社会生态预测因素的人，包括环境（例如，社会，邻里， 家庭），社会文化（例如，适应，信仰）和父母因素（例如，与睡眠有关的育儿 实践）在这个人群中。虽然睡眠不足和肥胖之间的关系已在 儿童和青少年，与幼儿的研究受到缺乏长期研究和父母使用的限制 儿童睡眠报告（而不是客观的睡眠量度）。此外，来自墨西哥裔美国人的幼儿 在这项研究中，家庭的人数不足，目的地是成长中最大的少数民族之一 在美国，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睡眠，而幼儿睡眠是否有助于不同 墨西哥裔美国家庭的幼儿肥胖症患病率。我们汇集了一个多学科 团队在儿科睡眠，肥胖和健康行为的社会生态学因素方面具有丰富的专业知识 （1）确定导致睡眠不足的环境，社会文化和父母因素，以及（2） 确定墨西哥幼儿2年内睡眠与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（重点 组）与墨西哥裔美国父母适应父母睡眠信念和与睡眠有关的措施 根据需要进行育儿实践。然后，我们将注册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）有12至15个月大的孩子居住在一个大都市地区 参加3个年度评估。在每个评估中，问卷和人体测量数据将是 收集的，父母和幼儿的睡眠将连续7天/夜晚进行测量（手腕 - 观察客观地测量睡眠的大小设备。这项创新的研究将提供深入的评估 父母和幼儿睡眠的生态学以及睡眠与幼儿的关系 目标人群的体重状况。为了确保孩子的整个家庭系统都被考虑，母亲， 将包括父亲和家里的其他主要护理人员。总共研究结果将有助于 以家庭为中心的，文化的和上下文知名的早期预防的未来发展 计划侧重于服务不足的人群的睡眠和体重状况。这项研究是下一步的关键 旨在减少健康差异并改善墨西哥裔美国人的幼儿中的健康状况 家庭。
