Fruit and Vegetable Intake Issues in Head Start Families

描述（由申请人提供）：低收入家庭患癌症、心血管疾病（CVD）、肥胖和糖尿病的风险增加，这些风险与不良饮食有关，特别是水果和蔬菜摄入量低（FVI）。不同照顾者的态度和行为，包括喂养的做法与儿童和CG FVI。这些CG影响的组织结构尚未在不同种族/族裔群体的低收入家庭中具体说明。我们提出了一种认知映射的方法来定义CG的FVI障碍和促进因素的看法，并模拟这些和CG喂养的做法，可用性和可及性如何与CG和儿童FVI在非西班牙裔白色（W），非西班牙裔非洲裔美国人（AA）和西班牙裔（H）的主要CG和他们的孩子从休斯顿，得克萨斯州和亚拉巴马州的头启动区。具体目标是：（1）使用名义群体技术（NGT）结构化焦点小组来识别家庭FVI的CG衍生障碍和促进因素;（2）使用这些CG问题的卡片分类来检查这些CG态度的组织，并从个人CG感知评级中加权这些CG重要性和做出适应性改变的信心;（3）评估儿童和CG的FVI和BMI、照顾者喂养实践和FV可用性和可及性;（4）将CG和儿童FVI模型作为这些心理社会评估和障碍和促进因素的加权聚类的函数;（5）描述在这些FVI相关性方面存在差异的家庭群体;（6）将相关性转化为绩效目标，以便将来进行量身定制的干预，以增加低收入家庭FVI。在每个目标中，我们将按种族/民族检查潜在差异。我们的多学科团队拥有在Head Start地区工作的专业知识和经验，评估儿童和成人FVI的相关性，CG认知映射和干预开发。这项建议解决了重要的未回答的问题，当回答将允许制定有效的干预措施，适合具体的CG特征。

DESCRIPTION (provided by applicant): Low-income families have increased risks for cancer, cardiovascular disease (CVD) obesity and diabetes related to adverse diets especially low in fruit and vegetable intake (FVI). Various caregiver (CG) attitudes and behaviors including feeding practices relate to child and CG FVI. The organizational structure of these CG influences has not been specified in low-income families in diverse race/ethnic groups. We propose a cognitive mapping approach to define CG perceptions of FVI barriers and facilitators and to model how these and CG feeding practices, availability and accessibility relate to CG and child FVI in Non-Hispanic White (W), Non-Hispanic African-American (AA) and Hispanic (H) primary CG and their children from Head Start districts in Houston, Texas and Alabama. The specific aims are to: (1) identify CG-derived barriers and facilitators to family FVI using Nominal Group Technique (NGT) structured focus groups; (2) examine the organization of these CG attitudes using card sorts of these CG issues and to weight these from individual CG perceived ratings of their personal importance and confidence for making adaptive changes; (3) assess child and CG FVI and BMI, caregiver feeding practices and FV availability and accessibility; (4) model CG and child FVI as functions of these psychosocial assessments and the weighted clusters of barriers and facilitators; (5) describe family groups differing in these relevant correlates of FVI; and (6) translate the relevant correlates to performance objectives for a future tailored intervention to increase low income family FVI. In each aim, we will examine potential differences by race/ethnicity. Our multidisciplinary team has expertise and experience working in Head Start districts, assessing correlates of FVI in children and adults, CG cognitive mapping and intervention development. This proposal addresses important unanswered questions that when answered will permit the development of effective interventions tailored to specific CG characteristics.
