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.

描述（由申请人提供）：美国成人和儿童的肥胖率高得惊人。鉴于与多种慢性健康状况的联系，肥胖率是一个 重大公共卫生问题。肥胖的病因是多因素的；然而，热量摄入过多是已知的主要因素之一。因此，健康促进和肥胖预防工作越来越强调改善膳食摄入。儿童的膳食摄入量与家庭食物环境直接相关，家庭食物环境是由家庭购买的食物组成的。然而，很少有研究调查这对父母和孩子购买食物的影响。拟议的二次分析“儿童和家长对食品购买的影响”（CAPIP）将利用社会生态框架调查对父母和儿童食品购买的多层次影响。调查父母和孩子的购买影响很重要，因为研究结果将对基于家庭的肥胖预防干预措施产生影响，在过去，这种干预措施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，通过用餐环境 (HOME) Plus 试验使用第二批健康家庭产品中 90 个家庭的数据。家庭调查数据包括 8-12 岁儿童及其主要准备膳食的父母的回答。拟议的 CAPIP 研究有两个主要目标。第一个是评估多层次购买影响项目的心理测量特性，例如家庭时间限制和烹饪技巧（通过 HOME Plus 进行测量，其中包括部分由申请人开发的新 HOME Plus 购买项目），并探索心理测量合理量表的开发以供未来研究。鉴于这些项目的新颖性，无论这些项目是形成规模还是作为单独的项目使用，研究结果都将为该领域做出贡献。第二个目标是评估家庭食品购买的影响，包括社会人口特征的差异及其与健康结果的关联。研究结果将检测在考虑社会人口特征和家庭食物供应情况时，儿童和父母对食物购买的影响在多大程度上解释了儿童食物摄入和体重结果的变异性。为了实现这些目标，将描述项目和量表的心理测量特性，进行因子分析，并测试描述性关联（例如相关性、卡方）和层次回归分析。这项研究的长期目标是扩大质量测量范围，并为量身定制的护理干预措施和服务提供信息，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，以解决肥胖流行的健康危机。
