Child and Parent Food Choices and Purchases: Contributions to Obesity

描述（由申请人提供）：在美国，成人和儿童的肥胖率高得惊人。考虑到与几种慢性健康状况的联系，肥胖率是一个 严重的公共卫生问题。肥胖的病因是多因素的;然而，过量的热量摄入是已知的主要贡献者之一。因此，健康促进和肥胖预防工作越来越强调改善饮食摄入。儿童的饮食摄入量与家庭食物环境直接相关，家庭食物环境由家庭购买的食物组成。然而，很少有研究调查对父母和孩子购买食物的影响。拟议的二次分析，儿童和父母的影响，食品购买（CAPIP），将调查多层次的影响，父母和儿童的食品购买使用社会生态框架。调查父母和孩子的购买影响很重要，因为研究结果将对以家庭为基础的肥胖预防干预措施产生影响，在过去，这比单独针对儿童或父母的干预措施产生了更积极的结果。CAPIP研究将采用横断面设计，使用来自健康家庭办公室第二队列的90个家庭的数据，通过进餐时间环境（HOME）Plus试验。家庭调查数据包括8-12岁儿童及其主要做饭父母的回答。拟议的CAPIP研究有两个主要目标。第一个是评估心理测量属性的多级购买影响项目，如家庭时间的限制和烹饪技能（如测量的HOME Plus，其中包括新的HOME Plus购买项目开发，部分，由申请人），并探讨发展的心理测量的声音尺度为未来的研究。鉴于这些项目的新奇，研究结果将有助于该领域的项目是否形成量表或作为单独的项目。第二个目标是评估购买粮食对家庭的影响，包括社会人口特征的差异及其与健康结果的关系。调查结果将检测儿童和父母对食物购买的影响如何强烈地解释儿童的食物摄入量和体重结果的变化，同时考虑社会人口特征和家庭食物供应。为了实现这些目标，将描述项目和量表的心理测量特性，进行因素分析，并描述相关性（例如，相关性，卡方）和分层回归分析。这项研究的长期目标是扩大质量测量，并提供量身定制的护理干预和服务，以改善食品购买，食品环境，营养摄入和家庭生活方式的健康状况，以解决肥胖流行病的健康危机。

DESCRIPTION (provided by applicant): Obesity rates of adults and children are alarmingly high in the United States. Given the link to several chronic health conditions, obesity rates are a substantial public health concern. The etiology of obesity is multifactorial; however, excessive caloric intake is one of the major known contributors. Therefore, health promotion and obesity prevention efforts have increasingly emphasized improving dietary intake. Children's dietary intake is directly related to the home food environment, which is made up of the foods purchased by a family. However, there is a paucity of research investigating the influences on food purchases for parents and children. The proposed secondary analysis, Child and Parent Influences on Food Purchasing (CAPIP), will investigate multilevel influences on parent and child food purchases using a social ecological framework. Investigating purchasing influences of both parents and children is important, as research findings will have implications for family-based obesity prevention interventions, which in the past, have led to more positive results than interventions targeted to children or parents separately. The CAPIP study will utilize a cross-sectional design using data from 90 families in the second cohort of the Healthy Home Offerings via the Mealtime Environment (HOME) Plus trial. Family survey data include responses from 8-12 year-old children and their primary meal- preparing parent. There are two main objectives of the proposed CAPIP study. The first is to assess the psychometric properties of multilevel purchasing influence items like family time constraints and cooking skills (as measured by HOME Plus, which includes new HOME Plus purchasing items developed, in part, by the applicant) and explore the development of psychometrically-sound scales for future research. Given the novelty of these items, the study findings will contribute to the field regardless of whether the items form scales or are used as individual items. The second objective is to evaluate the food purchasing influences for families, including their differences by sociodemographic characteristics and their associations with health outcomes. Findings will detect how strongly children's and parents' influences on food purchases explain variability in children's food intake and weight outcomes when accounting for sociodemographic characteristics and home food availability. To meet these objectives, item and scale psychometric properties will be described, factor analysis will be conducted, and descriptive associations (e.g., correlations, chi-square) and hierarchical regression analyses will be tested. The long-range goal of this study is to expand quality measurement and inform tailored nursing interventions and services that will improve the healthfulness of food purchases, food environments, nutritional intake, and lifestyles of families to address the health crisis of the obesity epidemic.
