项目摘要

DESCRIPTION (provided by applicant): In Texas, even the youngest children are affected by the obesity epidemic with 32% of 2 to 5 year old children overweight or obese before they enter school. The home environment and parenting skills and practices during the very early years of a child's life are critically important to establish obesity prevention behaviors such as healthy eating, physical activity, and adequate duration of sleep. However, parents lack these skills and interventions targeting the child's familiar environment, their home, are sparse. The overall aim of this study is to pilot test an integrated, culturally sensitive home-based program targeting predominantly low- income, African American and Hispanic parents to improve parenting skills for obesity prevention and control among toddlers ages 2 to 3 years. The program, PALS-CATCH, will integrate strategies from two research proven programs - Play and Learn Strategies (PALS) and the Coordinated Approach to Child Health (CATCH). This experimental study will target parents of toddlers in their home setting, teaching them how to be responsive and sensitive to their young child's cues, provide opportunities and assure consistency in young children's schedules for mealtime, activity, and sleep, thus facilitating child's development of self-regulation and other developmental outcomes to facilitate healthy eating, activity, and sleep patterns. Our specific aims are: Aim 1. To evaluate the feasibility and acceptability of PALS-CATCH among predominantly low-income, African American and Hispanic overweight or obese toddlers ages 2 to 3 years and their parents. Aim 2. To determine the effect of PALS-CATCH on child energy balance-related behaviors. We will use a randomized controlled trial (RCT) design to pilot test PALS-CATCH among 60 low-income, African American and Hispanic parent-child dyads where the child is overweight or obese (BMI >85th percentile for age and gender). We hypothesize that post-intervention, as compared to those in the control group, children of parents receiving PALS-CATCH will decrease: a) BMI z-score, and b) ounces of sugar-sweetened beverages consumed per day, and increase: e) number of servings of fruits and vegetables consumed per day and, f) mean minutes of physical activity including moderate-to-vigorous physical activity per day. As part of our secondary aims, we will evaluate the effects of PALS-CATCH on parent and child psychosocial and behavioral outcomes including parenting skills, responsiveness, and child self-regulation behaviors related to diet, physical activity, screen time and sleep. We will also examine the extent to which these factors mediate the improvements in child BMI, dietary and physical activity behaviors. Pre and post-intervention measurements will be conducted using child anthropometric measurements, parent-reported 24-hour dietary recalls for child dietary intake, accelerometers for child physical activity, video observations measuring parent responsiveness behaviors and, parent surveys measuring home environmental, and psychosocial factors. Results from the pilot will be used obtain effect sizes to power a RO1 to determine the efficacy of PALS-CATCH for toddlers.

描述（由申请人提供）：在德克萨斯州，即使是最小的孩子也受到肥胖流行的影响，32% 的 2 至 5 岁儿童在入学前超重或肥胖。孩子一生中的数年对于建立健康饮食、身体活动和充足睡眠等预防肥胖的行为至关重要，但父母缺乏这些技能，而且针对孩子熟悉的环境（即家庭）的干预措施也很少。这项研究的目的是试点测试一个综合的、文化敏感的家庭计划，主要针对低收入、非裔美国人和西班牙裔父母，以提高 2 至 3 岁幼儿肥胖预防和控制的育儿技能。，将整合来自两个经过研究验证的计划的策略——玩耍和学习策略（PALS）和儿童健康协调方法（CATCH）。这项实验性研究将以家庭环境中的幼儿家长为对象，教他们如何对孩子的健康做出反应和敏感。他们的年轻人我们的具体目标是：目标 1。 . 评估 PALS-CATCH 在 2 至 3 岁超重或肥胖幼儿及其父母中的可行性和可接受性目标 2. 确定 PALS-CATCH 的效果。我们将使用随机对照试验 (RCT) 设计，在 60 个低收入、非裔美国人和西班牙裔亲子二人组中进行 PALS-CATCH 试点测试，其中儿童超重或肥胖（BMI > 85）。我们勇敢地承认，干预后，与对照组相比，接受 PALS-CATCH 的父母的孩子将减少：a) BMI z 分数，b) 盎司。每天消耗的含糖饮料，并增加： e) 每天消耗的水果和蔬菜份数，以及， f) 平均体力活动时间，包括每天中度至剧烈的体力活动作为我们次要目标的一部分，我们将评估 PALS-CATCH 对父母和孩子心理社会和行为结果的影响，包括养育技能、反应能力以及与饮食、身体活动、屏幕时间和睡眠相关的儿童自我调节行为。我们还将检查这些影响的程度。影响儿童进步的因素将使用儿童人体测量数据、家长报告的儿童饮食摄入量 24 小时饮食回忆、儿童身体活动加速度计、视频来进行干预前和干预后的 BMI、饮食和身体活动行为测量。测量家长反应行为的观察结果以及测量家庭环境和心理社会因素的家长调查将用于获得效应大小，为 RO1 提供动力，以确定 PALS-CATCH 对幼儿的功效。
