项目摘要

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.

描述（由申请人提供）：在农场儿童中，超重和肥胖症普遍存在，其中绝大多数是墨西哥血统的拉丁裔。不幸的是，在农场工作者儿童中，有几乎没有系统的研究重点是儿童超重 - 体育锻炼和饮食的主要决定因素。因此，在这种健康状况不佳和医疗服务不足的人群中，在文化和上下文上建立适当的干预策略的经验基础受到了损害。从根本上讲，拉丁裔农民儿童的体育锻炼和饮食模式是工作家庭问题。农场工作的性质和农场工作者的生活方式为儿童健康的生活方式习惯带来了重大障碍，并且在一群已经有不良健康和发育成果风险的儿童中表现出肥胖的升高。该研究项目的目的是加强建立饮食和体育锻炼干预计划的经验基础，以解决年轻的拉丁裔农场儿童的超重和肥胖。为了实现这一目标，我们建立在长期以来的学术界伙伴关系的基础上，重点介绍了农场工作者家庭健康的：1）记录农民家庭家庭的年轻（3岁）儿童的饮食和身体活动模式； 2）确定有助于青球饮食和体育锻炼行为的孩子，家族，社区和文化因素； 3）在文化和上下文上确定改善拉丁裔农民儿童饮食和体育锻炼模式的策略。拟议的项目的特定目标将使用综合定性研究设计来实现，该研究将通过两个不同的项目组件进行。定性项目组成部分涉及对农场儿童母亲的深入个人访谈（n = 30），以对农场工人家庭对儿童体重和肥胖的信念产生全面的了解，以及塑造儿童饮食和身体活动模式的因素。该项目组成部分的结果将有助于确定塑造儿童饮食和体育锻炼模式的具体因素，并且它们将为第二个项目组成部分的内容提供信息。第二个项目组成部分涉及对农民儿童饮食和体育锻炼模式的定量评估。将使用基于站点的抽样策略招募3年历史的儿童及其母亲（n = 250）的代表性样本，并在两年期间每三个月评估一次。数据收集包括24小时饮食召回，使用加速度计来收集儿童体育锻炼的客观评估以及孕产妇访谈。该项目组成部分的结果将为儿童的饮食和身体活动行为提供强有力的描述。它们还将通过针对特殊危险儿童，确定有效干预措施中要解决的特定因素，并辨别实施干预措施的理想时间段来对干预开发有用。公共卫生相关性：该项目侧重于年轻的拉丁裔农民儿童的饮食和体育锻炼模式。农场工作者的儿童是医疗服务不足和健康不同的人群。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作者超重或肥胖，以及如何设计干预计划，通过促进健康的饮食和身体习惯，从而减少这些儿童的超重和肥胖。
