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.

项目摘要尽管通过社会经济地位（SES）持续超重/肥胖（OW/O）分布来自低SES背景的学龄前儿童稀疏。基于代际传播习惯和肥胖，针对学龄前儿童及其护理人员（父母或法定监护人）只是一个预防OW/O的有前途的策略。该项目将确定在3-5岁时，他们的护理人员及其护理人员之间的创新跨学龄前儿童之间的代际干预措施。方法：将进行两组群集随机对照试验。六个头开始中心将是随机分配给干预措施（n = 3）或对照组（n = 3），而24个护理人员毕业生二元组将是从每个中心招募（n = 144个二元组）。基于参与者 - 伴侣相互依存模型（APIM）， 16周干预有3个组件：1）一个护理人员组件，包括1A）一个基于Facebook的程序每周可检索的传单提供健康信息和行为改变策略，4 每周的习惯性任务，以改善学龄前儿童的育儿习惯和家庭环境；和1b）3 面对面的会议（WKS。1、8和16），以建立个人联系和交流网络护理人员，讨论策略并共享社区资源，以支持学龄前儿童的行为改变家; 2）通过Facebook Messenger通过Facebook Messenger的护理人员学龄前儿童学习组件将学龄前信件发送给研究团队每周两次私下护理人员到2A）分享学龄前儿童的经历在学校学习以及他/她对在家健康饮食和体育锻炼的兴趣，以及2B）看护人对信件的回应； 3）一个基于中心的启动前学龄前儿童组件来帮助学龄前儿童通过每周健康的饮食和体育锻炼参与学习来养成健康的习惯。目标1：确定干预措施的初步效率与对学龄前儿童近端行为的控制（例如MVPA，饮食质量）和远端人体测量结果（例如，OW/O的比例，BMI z得分）。目标2：检查干预的初步效率与护理人员的行为和人体测量结果的控制。目标3：比较干预与对双向关系的控制（在APIM中提出）和学龄前儿童之间 MVPA，饮食质量和屏幕时间的护理人员。创新：干预措施超出了先验研究仅着眼于双向护理人员对学龄前儿童的单向影响还强调学龄前儿童对看护人的影响的方法。可持续性的潜力和可伸缩性很高，因为干预措施被整合到日常工作中，并利用已经存在的 - 现有的社交网络Facebook将护理人员连接到在线私人小组。它促进了通过学龄前儿童进行学龄前儿童偏好的交流，以改善看护者的育儿惯例通过Facebook Messenger发送给护理人员的信件。影响：拟议的研究将为未来树立舞台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。
