Influences on Physical Activity of Young Latino Children

描述(由申请人提供)：体力活动是能量平衡的一个关键组成部分，因此促进它是预防儿童超重的一个重要组成部分。很少有研究考察环境对3-5岁拉美裔儿童身体活动和久坐行为的多重影响，他们在低收入美国学龄前儿童中风险和超重的患病率最高。研究表明，解决儿童肥胖问题的干预措施对拉丁裔家庭及其学龄前儿童有效，需要文化定制和强有力的父母因素。这项拟议的研究将使用定性的方法来探索父母、家庭和家庭环境以及社会文化对儿童身体活动和久坐行为的影响；并从服务于罗德岛州拉美裔人口的父母和WIC计划工作人员的角度确定提供身体活动机会的障碍和促进者。关于家长和学龄前儿童体力活动的量化数据，通过加速计和家长报告进行评估，将补充用于设计将由世界儿童基金会管理的教育干预措施的定性主题。四个连续阶段包括：第一阶段：A：与罗德岛州参加WIC方案的学龄前儿童的父母进行焦点小组讨论，B：与WIC工作人员进行深入访谈；第二阶段：衡量n=30名父母及其学龄前儿童的客观和报告的体力活动；第三阶段：制定教育干预措施，解决：(A)父母，(B)家庭/家庭环境，以及(C)社会文化对低收入拉丁裔学龄前儿童身体活动和久坐行为的影响；第四阶段：对材料和方案进行定性评估和改进，形成适合通过随后的RO1应用程序进行正式测试的全面教育干预措施。这项拟议的研究不仅将通过关注低收入的拉丁裔学龄前儿童及其家庭来增加现有的知识，还将展示诸如WIC计划这样的组织可以通过教育干预在培养父母能力和技能方面发挥潜在的作用，以促进这些超重高危人群增加体力活动和减少久坐行为。公共卫生相关性：拟议的研究将探索父母、家庭和家庭环境以及社会文化影响，并确定改善低收入拉丁裔学龄前儿童体力活动和久坐行为的障碍和促进者。来自与父母的焦点小组的定性研究结果，以及对妇女、婴儿和儿童特别补充食品计划(WIC)工作人员的深入采访，以及通过加速计和父母报告评估的父母和儿童体力活动的定量数据，将被用来为这一超重高危目标人群制定教育干预措施。WIC工作人员将提供个人、团体和电话咨询的材料、脚本和协议，这些材料、脚本和协议将在文化上量身定做，以促进在这种组织环境中早期健康的体育活动行为。

DESCRIPTION (provided by applicant): Physical activity is a key component of energy balance and its promotion therefore an essential component in the prevention of child overweight. Few studies have examined multiple contextual influences on physical activity and sedentary behaviors of Latino-children 3-5 yr, who have the highest prevalence of at risk and overweight among low income US preschoolers. Research suggests interventions addressing childhood obesity that will be effective for among Latino families and their preschool children require cultural tailoring and a robust parent component. The proposed study will use qualitative methods to explore parental, family and home environment, and social-cultural influences on children's physical activity and sedentary behaviors; and identify barriers and facilitators to providing opportunities for physical activity from the perspectives of parents and WIC Program staff serving Latino populations in Rhode Island. Quantitative data on physical activity of parents and preschool children assessed by accelerometry and parental report will complement qualitative themes used to design an educational intervention to be administered by WIC. Four sequential phases include: Phase I: A: focus group discussions with parents of preschool-aged children enrolled in the WIC program in the state of Rhode Island, and B: In-depth interviews with WIC staff; Phase II: measurement of objective and reported physical activity of n=30 parents and their preschool-aged children; Phase III: development of an educational intervention that addresses: (a) parental, (b) family/home environment, and (c) socio-cultural influences on physical activity and sedentary behaviors of low income, Latino preschool children; Phase IV: qualitative evaluation and refinement of materials and protocols, resulting in a fully developed educational intervention suitable for formal testing through a subsequent RO1 application. The proposed research will add to current knowledge not only through a focus on low-income, Latino preschool children and their families, but also demonstrating the potential role organizations such as the WIC Program can play in building parenting capacity and skills through educational interventions to promote increased physical activity and decreased sedentary behaviors of this population at high risk of overweight. Public Health Relevance: The proposed research will explore parental, family and home environment, and social-cultural influences and identify barriers and facilitators to improving physical activity and sedentary behaviors of low-income, Latino, preschool children. Qualitative research findings from focus groups with parents and in-depth interviews with staff of the Special Supplemental Food Program for Women, Infants and Children (WIC) and quantitative data on physical activity of parents and children assess by accelerometry and parental report will be used to develop an educational intervention for this target population at high risk of overweight. Materials, scripts and protocols for individual, group and phone counseling to be delivered by WIC staff will be culturally tailored to promote early healthy physical activity behaviors in this organizational setting.
