Behavior and beliefs related to diet in Native Hawaiians in Southern California

描述(由申请人提供)：该项目是奥兰治县和洛杉矶县的夏威夷原住民社区和加州州立大学富勒顿分校(CSUF)合作开发的一份关于饮食习惯相关行为和信念的调查问卷。夏威夷原住民社区成员将参与该项目的所有阶段，从提出文化问题、审查和评价最终问卷、招募参与者、管理问卷到数据分析。通过测量社区中与营养相关的知识范围，以及与饮食习惯和饮食摄入量相关的行为和信念，我们将收集数据，最终开发一项符合文化背景的饮食干预研究，该研究将以南加州夏威夷原住民社区为目标，以降低癌症风险为主要目标。具体目标1：通过24小时饮食召回，测量居住在奥兰治县和洛杉矶县的60名夏威夷原住民(21岁及以上)的膳食摄入量，包括蔬菜、水果、宏量和微量营养素的摄入量。具体目标2：开发和试行一份问卷，衡量60名夏威夷原住民成年人的行为和信仰，以及与饮食习惯/行为有关的文化因素。目标2 A/2B：将根据社会和行为理论(社会认知理论和跨理论模型)以及以往研究中使用的现有问卷提出量化问题。量化问题将基于以下与饮食习惯相关的心理社会量表：社会支持、自我效能、结果预期、计划、准备、份量控制、社会互动、认知-行为策略和行为变化的阶段。目标2C：将开发定性问题，以探索夏威夷原住民饮食行为(与饮食习惯、饮食摄入量和饮食变化相关的文化含义)特有的文化和文化适应因素。目的2D：新开发的定量和定性问卷将通过自我报告的方式在60名夏威夷原住民社区成员中试行。具体目标3：评估关于饮食习惯的行为和信念与通过24小时饮食回忆测量的饮食摄入量之间的关系。这项研究将第一次在南加州的夏威夷原住民社区中发展和测量与饮食习惯和饮食摄入量相关的行为和信念。这项研究的结果将对开发文化敏感的饮食干预/教育计划至关重要，该计划不仅将产生短期的饮食变化，而且将有效地导致持续的饮食调整，努力降低这个研究不足的社区的癌症发病率。

DESCRIPTION (provided by applicant): The proposed project is a collaborative effort between the Native Hawaiian community in Orange and Los Angeles counties and California State University Fullerton (CSUF) in the development of a culturally relevant questionnaire on behavior and beliefs related to eating habits. Native Hawaiian community members will be involved in all phases of this project from developing culturally specific questions, review and critique of the final questionnaire, recruitment of participants, administering the questionnaire to data analysis. By measuring the range of knowledge related to nutrition in the community, and behavior and beliefs associated with eating habits and dietary intakes, we will gather data to eventually develop a culturally appropriate dietary intervention study that will target the Native Hawaiian community in Southern California with a primary goal to reduce cancer risk. Specific Aim 1: To measure dietary intakes, including vegetable, fruit, macro- and micronutrient intakes, via 24-hour dietary recalls in 60 Native Hawaiian adults (21 yrs and older) residing in Orange and Los Angeles counties. Specific Aim 2: To develop and pilot a questionnaire that measures behavior and beliefs, and cultural factors related to eating habits/behaviors in 60 Native Hawaiian adults. Aim 2A/2B: Quantitative questions will be developed based on social and behavioral theories (Social Cognitive Theory and Transtheoretical Model) and on existing questionnaires used in previous studies. Quantitative questions will be constructed based on the following psychosocial scales related to eating habits: social support, self-efficacy, outcome expectations, planning, preparation, portion control, social interactions, cognitive-behavioral strategies and stages of behavioral change. Aim 2C: Qualitative questions will be developed to explore cultural and acculturation factors specific to dietary behavior (cultural meanings associated with eating habits, dietary intake and change in diet) in Native Hawaiians. Aim 2D: The newly developed quantitative and qualitative questionnaire will be piloted in 60 Native Hawaiian community members in-person via self-report. Specific Aim 3: To assess the relationship between behavior and beliefs regarding eating habits with dietary intakes measured via 24-hour dietary recalls. The present study will be the first to develop and measure behavior and beliefs related to eating habits and dietary intakes in the Native Hawaiian community in Southern California. The findings of this study will be critical to developing a culturally sensitive dietary intervention/education program that will not only produce short term dietary change, but also will be efficacious in resulting in sustained dietary modification in efforts to reduce cancer rates in this understudied community.
