项目摘要

PROJECT SUMMARY Despite persistent overweight/obesity (OW/O) disparities by socioeconomic status (SES), interventions targeting preschoolers from low-SES backgrounds are sparse. Based on the intergenerational transmission of habits and obesity, targeting preschoolers and their caregivers (parents or legal guardians) simultaneously is a promising strategy for the prevention of OW/O. This project will determine the preliminary efficacy of an innovative intergenerational intervention among Head Start preschoolers, aged 3-5 years, and their caregivers. Methods: A two-group cluster randomized controlled trial will be conducted. Six Head Start centers will be randomly assigned to the intervention (n=3) or control group (n=3), and 24 caregiver-preschooler dyads will be recruited from each center (N=144 dyads). Grounded in an Actor-Partner Interdependence Model (APIM), the 16-week intervention has 3 components: 1) a caregiver component, including 1a) a Facebook-based program with weekly electronic retrievable flyers providing health information and behavioral change strategies and 4 weekly habit-formation tasks to improve parenting practices and home environment for preschoolers; and 1b) 3 face-to-face meetings (wks. 1, 8, & 16) to establish personal connections and communication networks among caregivers, discuss strategies, and share community resources to support preschoolers’ behavioral changes at home; 2) a caregiver-preschooler learning component via Facebook messenger to send preschooler letters to each caregiver privately by the research team twice per week to 2a) share the preschooler’s experiences of learning at school and his/her interests for a healthy diet and physical activity at home, and 2b) elicit caregivers’ response to the letters; and 3) a Head Start center-based preschooler component to help preschoolers establish healthy habits via weekly healthy diet and physical activity participatory learning. AIM 1: Determine the preliminary efficacy of intervention vs control on preschoolers’ proximal behavioral (e.g., MVPA, diet quality) and distal anthropometric outcomes (e.g., proportion of OW/O, BMI z-score). AIM 2: Examine the preliminary efficacy of intervention vs control on caregivers’ behavioral and anthropometric outcomes. AIM 3: Compare intervention vs control on the bidirectional relationship (proposed in APIM) between preschoolers and caregivers on MVPA, diet quality, and screen time. Innovation: The intervention extends beyond prior research that focuses only on the unidirectional influence of caregivers on preschoolers with a bidirectional approach that also emphasizes the influence of preschoolers on caregivers. The potential for sustainability and scalability is high because the intervention is integrated into daily routines and capitalizes on the already- existing social network Facebook to connect caregivers to an online private group. It facilitates the communication of preschooler preferences to improve caregivers’ parenting practices through preschooler letters sent to caregivers via Facebook messenger. Impact: The proposed study will set the stage for a future large-scale study to prevent and reduce OW/O and promote health among underserved preschoolers.
项目摘要 尽管社会经济地位(SES)的超重/肥胖(OW/O)差异持续存在,但干预措施 以低社会经济地位背景的学龄前儿童为目标的情况很少。基于代际传递, 习惯和肥胖,同时针对学龄前儿童和他们的照顾者(父母或法律的监护人)是一个 预防OW/O的有效策略。该项目将确定一种 在3-5岁的学前儿童和他们的照顾者中进行创新的代际干预。 方法:采用两组整群随机对照试验。六个先行中心将 随机分配到干预组(n=3)或对照组(n=3),将24个成年人-学龄前儿童二对组合, 从每个中心招募(N=144对)。基于演员-合作伙伴相互依赖模型(APIM), 16-一周的干预有3个组成部分:1)护理人员组成部分,包括1a)基于Facebook的计划 每周电子检索传单提供健康信息和行为改变策略, 每周一次的习惯养成任务,以改善学龄前儿童的育儿方法和家庭环境;以及1b)3 面对面会议(第1、8和16周),以建立个人联系和沟通网络, 照顾者,讨论策略,并分享社区资源,以支持学龄前儿童的行为改变, 2)通过Facebook Messenger发送学龄前儿童信件给 每个照顾者私下由研究小组每周两次,以2a)分享学龄前儿童的经验, 在学校学习和他/她的兴趣,健康饮食和体育活动在家里,和2b)引出 照顾者对信件的反应;以及3)一个基于Head Start中心的学前教育组件,以帮助 学龄前儿童通过每周健康饮食和体育活动参与式学习建立健康习惯。目标1: 确定干预与控制对学龄前儿童近端行为(例如,MVPA, 饮食质量)和远端人体测量结果(例如,OW/O比例,BMI z评分)。目的2:检查 干预与控制对照顾者行为和人体测量结果的初步疗效。目标3: 比较干预与控制的双向关系(提出在APIM)之间的学龄前儿童和 护理人员的MVPA、饮食质量和屏幕时间。创新:干预超越了先前 研究只关注照顾者对学龄前儿童的单向影响, 这种方法也强调了学龄前儿童对照顾者的影响。可持续性的潜力, 可扩展性很高,因为干预措施被纳入日常工作,并利用了已经存在的 现有的社交网络Facebook将护理人员与在线私人团体联系起来。它促进 通过学前教育交流幼儿偏好以改善照顾者的育儿实践 通过Facebook Messenger发送给护理人员的信件。影响:拟议的研究将为未来奠定基础 大规模研究,以预防和减少OW/O,并促进服务不足的学龄前儿童的健康。
