Dietary & Physical Activity Patterns of Latino Farmworker Children

描述（由申请人提供）：超重和肥胖在农场工人儿童中很普遍，其中绝大多数是墨西哥血统的拉丁美洲人。不幸的是，很少有系统的研究集中在儿童超重的主要决定因素-体力活动和饮食-在农场工人的孩子。因此，建立文化和背景适当的干预战略，以预防或治疗儿童超重和肥胖的健康差异和医疗服务不足的人口的经验基础受到损害。拉丁美洲农场工人儿童的体育活动和饮食模式从根本上说是一个工作-家庭问题。农场工作的性质和农场工人的生活方式对儿童的健康生活习惯构成了重大障碍，这表现在一组已经处于健康和发育不良风险中的儿童肥胖率上升。 本研究项目的目标是加强建立饮食和体育活动干预计划，以解决超重和肥胖的年轻拉丁美洲农场工人的孩子的经验基础。为了实现这一目标，我们建立了一个长期的学术界合作伙伴关系，专注于农场工人家庭健康：1）记录年轻人的饮食和身体活动模式，（3岁）农场工人家庭的儿童; 2）确定儿童，家庭，社区和文化因素，有助于肥胖的饮食和体育活动行为;和3）确定文化和上下文适当的战略，以改善饮食和体力活动模式的拉丁美洲农场工人的孩子。 拟议项目的具体目标将通过两个不同的项目组成部分采用综合的定性-定量研究设计来实现。定性项目的组成部分涉及到深入的个人访谈与农民工儿童的母亲（n=30），以发展的信念，农民工家庭对儿童的体重和肥胖症的全面理解，以及塑造儿童的饮食和体育活动模式的因素。该项目组成部分的结果将有助于确定影响儿童饮食和体育活动模式的具体因素，并将为第二个项目组成部分的内容提供信息。项目的第二个组成部分涉及对农场工人儿童的饮食和体育活动模式进行定量评估。将使用基于站点的抽样策略招募3岁农场工人儿童及其母亲（n=250）的代表性样本，并在两年期间每三个月进行一次评估。数据收集包括24小时饮食回顾，使用加速计收集儿童身体活动的客观评估，以及母亲访谈。该项目的结果将提供儿童饮食和体育活动行为的有力描述。它们还将有助于制定干预措施，特别是针对风险儿童，确定有效干预措施中需要解决的具体因素，并确定实施干预措施的理想时间段。公共卫生相关性：该项目的重点是年轻的拉丁美洲农场工人儿童的饮食和身体活动模式。农场工人的孩子是一个医疗服务不足和健康不同的人口。该项目的结果将帮助卫生工作者更好地确定有多少农场工人儿童超重或肥胖，以及如何设计干预方案，通过促进健康饮食和生活早期的身体习惯来减少这些儿童的超重和肥胖。

DESCRIPTION (provided by applicant): Overweight and obesity is prevalent among farmworker children, the vast majority of whom are Latino of Mexican descent. Unfortunately, there has been little systematic research focused on the primary determinants of childhood overweight - physical activity and diet - among farmworker children. The empirical foundation for building culturally and contextually appropriate intervention strategies for preventing or treating childhood overweight and obesity in this health disparate and medically underserved population is therefore compromised. The physical activity and dietary patterns of Latino farmworker children is fundamentally a work-family issue. The nature of farmwork and the farmworker lifestyle poses significant barriers to healthy lifestyle habits among children, and it manifests in elevated obesity in a group of children already at risk for poor health and developmental outcomes. The goal of this research project is to strengthen the empirical foundation upon which to build diet and physical activity intervention programs to address overweight and obesity among young Latino farmworker children. To achieve this goal, we build on a long-standing academic community partnership focused on farmworker family health to: 1) document the dietary and physical activity patterns of young (3 year-old) children of farmworker families; 2) determine the child, familial, community, and cultural factors that contribute to obesigenic dietary and physical activity behavior; and 3) identify culturally and contextually appropriate strategies for improving dietary and physical activity patterns of Latino farmworker children. The proposed project's specific aims will be accomplished using an integrated qualitative-quantitative study design that will occur through two distinct project components. The qualitative project component involves in- depth personal interviews with mothers of farmworker children (n=30) to develop a comprehensive understanding of the beliefs farmworker families have about children's weight and obesity, and the factors shaping children's diet and physical activity patterns. Results of this project component will be useful in identifying the concrete factors that shape children's eating and physical activity patterns, and they will inform the content of the second project component. The second project component involves quantitative assessment of farmworker children's dietary and physical activity patterns. A representative sample of 3 year- old farmworker children and their mothers (n=250) will be recruited using a site-based sampling strategy and assessed every three months over a two year period. Data collection includes 24-hour dietary recalls, use of accelerometers for collecting objective assessments of children's physical activity, and maternal interviews. The results of this project component will provide robust descriptions of children's dietary and physical activity behavior. They will also be useful for intervention development by targeting particularly at-risk children, identifying specific factors to be addressed in effective interventions, and discerning ideal time periods for implementing interventions. PUBLIC HEALTH RELEVANCE: The project focuses on the dietary and physical activity patterns of young Latino farmworker children. Farmworker children are a medically underserved and health disparate population. The results of this project will help health workers better determine how many farmworker children are overweight or obese, and how to design intervention programs that reduce overweight and obesity in these children by promoting healthy diet and physical habits early in life.
