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，与不良饮食有关，尤其是水果和蔬菜摄入量（FVI）低。各种照顾者（CG）的态度和行为，包括喂养方法与儿童和CG FVI有关。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得到具体说明。我们提出了一种认知映射方法来定义CG对FVI障碍和促进因素的看法，并对来自休斯顿、德克萨斯州和阿拉巴马州的非西班牙裔白人(W)、非西班牙裔非裔美国人（AA）和西班牙裔(H)初级CG及其孩子的CG和儿童FVI的做法、可用性和可及性进行建模。具体目标是：(1)使用名义群体技术（NGT）结构化焦点小组确定cg衍生的家庭FVI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，并根据个人CG感知的个人重要性和做出适应性改变的信心评级来衡量这些态度；(3)评估儿童和儿童的FVI和BMI，照料者喂养方法和FV的可用性和可及性；(4)模拟CG和儿童FVI作为这些心理社会评估的功能以及障碍和促进因素的加权聚类；(5)描述在这些与FVI相关的因素中不同的家族群体；(6)将与绩效目标相关的因素转化为未来量身定制的干预措施，以提高低收入家庭的FVI。在每个目标中，我们将按种族/民族检查潜在的差异。我们的多学科团队在学前教育地区拥有专业知识和经验，评估儿童和成人FVI的相关性，CG认知绘图和干预发展。该建议解决了一些重要的未解问题，这些问题得到回答后，将允许针对特定CG特征制定有效的干预措施。

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.
