Factors influencing screen media use in low-income Mexican American toddlers

项目总结/摘要 低收入的拉丁裔儿童从幼年开始就不成比例地受到肥胖的影响。身体不好 行为导致肥胖，甚至从这么小的时候开始。不健康的屏幕使用行为是已知的 ≥ 3岁儿童睡眠时间短、饮食不良和肥胖的预测因素，随着年龄的增长， 儿童的证据<3。因为低收入的拉丁裔儿童更有可能使用不健康的屏幕 行为比低收入非拉丁裔白色儿童，干预措施解决屏幕使用在这一人群 是减少肥胖差距的关键。包括我们自己在内的证据表明， (TV)使用行为和与电视相关的父母教养方式是3岁以上儿童电视使用的预测因子。今天， 然而，超过80%的儿童在3岁之前使用屏幕设备（例如电视，平板电脑）。尽管如此，目前 了解3岁之前屏幕使用发展的因素，或这些因素之间的关系。 早期筛查与睡眠、饮食、体力活动和体重指数（BMI）有关。因为屏幕使用行为 在整个童年时期，在3岁之前干预屏幕使用可能会产生持久的影响。通过推进 我们对屏幕使用行为如何发展以及与低- 收入<3岁的拉丁裔儿童，我们可以开始制定早期生活干预措施，以减少不健康的屏幕使用， 这个人口。这个应用程序的目标是确定与儿童早期屏幕使用行为相关的因素 以及这些行为如何反过来与儿童健康结果相关。在这5- 在为期一年的研究中，我们将招募15 - <27个月奥尔兹的低收入墨西哥裔美国母亲和父亲。 使用混合方法的方法，我们将首先收集定性数据，从约40名母亲和父亲，以确定 与儿童屏幕使用相关的父母行为和文化因素，以便适应/制定相关措施 年龄组（目标1）。然后，我们将从385个家庭收集定量数据，以评估 父母屏幕相关行为，儿童屏幕使用，儿童睡眠时间，饮食，身体活动和BMI (Aim 2）并评估社会文化因素与父母屏幕相关行为的关联（目标3）。 我们基于家庭系统理论的中心假设是，母亲和父亲的屏幕使用和屏幕- 相关的育儿实践塑造了儿童屏幕的使用，这与睡眠时间较短，饮食不良， 更少的体力活动和更高的BMI。基于生态模型，我们还假设父母筛选- 相关行为发生在社会文化背景下。我们的长期目标是设计一个基于诊所的 在低收入的墨西哥裔美国儿童中促进健康屏幕使用的干预< 3岁。本研究 将产生关于父母屏幕相关行为与儿童屏幕使用之间关系的新数据， 相关的健康结果，以及这些行为发生的背景。在这个高度数字化的时代， 在很小的年龄引入无障碍屏幕，我们必须确定与早期 屏幕使用，以便我们可以有效地促进健康的屏幕使用行为，当他们第一次发展。

Project Summary/Abstract Low-income Latino children are disproportionately affected by obesity starting in early life. Poor health behaviors contribute to obesity, even from this early age. Unhealthy screen use behaviors are known predictors of short sleep duration, poor diet, and obesity in children ≥ 3 years old, with growing, yet limited, evidence in children <3. Because low-income Latino children are more likely to have unhealthy screen use behaviors than low-income non-Latino white children, interventions addressing screen use in this population are critical to efforts to reduce obesity disparities. Evidence, including our own, suggests parental television (TV) use behaviors and TV-related parenting practices are predictors of TV use in children ≥ 3. Today, however, >80% of children use screen devices (e.g. TV, tablet) before age 3. Despite this, little is currently known about the factors contributing to the development of screen use before age 3, or the relationship of such early screen use with sleep, diet, physical activity, and body mass index (BMI). Because screen use behaviors track throughout childhood, intervening on screen use before age 3 may have a lasting impact. By advancing our understanding of how screen use behaviors develop and are related to health outcomes among low- income Latino children <3, we can begin to develop early life interventions to reduce unhealthy screen use in this population. This application’s objective is to identify factors related to early childhood screen use behaviors in low-income Latino children and how those behaviors are, in turn, related to child health outcomes. In this 5- year study, we will recruit low-income Mexican American mothers and fathers with 15 - <27 month olds. Using a mixed methods approach, we will first collect qualitative data from ~40 mothers and fathers to identify parental behaviors and cultural factors related to child screen use in order to adapt/develop measures for this age group (Aim 1). We will then collect quantitative data from 385 families to evaluate associations among parental screen-related behaviors, child screen use, and child sleep duration, diet, physical activity, and BMI (Aim 2) and evaluate the association of sociocultural factors with parental screen-related behaviors (Aim 3). Our central hypothesis, based on family systems theory, is that mothers’ and fathers’ screen use and screen- related parenting practices shape child screen use, which is associated with shorter sleep duration, poor diet, less physical activity, and greater BMI. Based on the ecological model, we also hypothesize parental screen- related behaviors occur within a sociocultural context. Our long-term goal is to design a clinic-based intervention promoting healthy screen use in low-income Mexican American children < 3 years old. This study will produce novel data on the relationship of parental screen-related behaviors with child screen use and related health outcomes, and the context within which these behaviors occur. In this digital era of highly accessible screens introduced at very early ages, it is imperative that we identify factors associated with early screen use so that we can effectively promote healthy screen use behaviors when they are first developing.
