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，特别是水果和蔬菜摄入量(FVI)较低。不同的照顾者(CG)态度和行为，包括喂养实践，与儿童和CG FVI有关。在不同种族/民族的低收入家庭中，这些CG影响的组织结构尚未具体说明。我们提出了一种认知图谱方法来定义CG对FVI障碍和促进器的感知，并模拟这些和CG喂养实践、可用性和可及性如何与来自休斯顿、德克萨斯州和阿拉巴马州Head Start地区的非西班牙裔白人(W)、非西班牙裔非裔美国人(AA)和西班牙裔(H)小学CG及其子女的CG和儿童FVI相关。其具体目标是：(1)使用名义群体技术(NGT)结构化焦点小组来确定CG衍生的障碍和家庭FVI的促进者；(2)使用卡片检查这些CG态度的组织，并根据单个CG对其个人重要性和做出适应性改变的信心的感知评级来加权；(3)评估儿童和CG FVI和BMI、照顾者喂养实践以及FV的可得性和可获得性；(4)将CG和儿童FVI作为这些心理社会评估的函数以及障碍和促进者的加权集群；(5)描述在这些与FVI相关的不同的家庭群体；以及(6)将相关因素转化为绩效目标，以便在未来进行量身定制的干预，以增加低收入家庭的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Head Start地区拥有专业知识和经验，评估儿童和成人FVI的相关性，CG认知图谱和干预开发。这项建议涉及尚未回答的重要问题，这些问题一旦得到回答，就可以根据具体的群体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.
