DESCRIPTION (provided by applicant): Obesity presents an increasingly important modifiable cancer-related risk factor for populations, yet little is known about the ways to prevent and control obesity for ethnically diverse populations. Pacific Islanders experience high rates of obesity and cancer, presenting an opportunity for exploration leading to intervention development and testing, yet they remain invisible and understudied to the academic community. This two year exploratory study seeks to understand the obesity-related influences for Pacific Islander (PI) youth in Southern California. Using a Community-Based Participatory Research (CBPR) approach involving four community-based agencies and three universities, the goals of this project are to: 1) to test the feasibility of various quantitative and qualitative data collection activities among Marshallese, Samoan and Tongan adolescents; and 2) estimate the point prevalence of obesity and physical activity. A sub-aim is to explore the distribution of dietary intake in these groups; and 3) explore the predisposing, enabling and reinforcing factors influencing physical activity in this group. The specific aims of the study are: a.) Convene quarterly meetings of the Community Advisory Committee (CAC) throughout the conduct of this study to inform the development and implementation of all study methods and community outreach activities; b.) Design and facilitate focus groups with PI adolescents, aged 14-18 years, from three Pacific Islander populations (Marshallese, Samoans and Tongan) to explore influences on obesity and physical activity: i. Types of physical activity performed, including location, frequency and purpose; ii. Cultural factors, including identity, acculturation and cultural beliefs; iii. Environmental issues that present enabling opportunities and barriers to adolescents; iv. Individual factors, including predisposing and reinforcing influences; c.) Implement protocols for collection of objective measures of obesity and physical activity among adolescents: i. Height and weight for calculations of body mass index; ii. Accelerometer data for calculations of time spent in moderate and vigorous intensity physical activities; d.) Design and/or pretest a survey instrument to assess: I. Predisposing and reinforcing influences on adolescent physical activity; (also listed in b iv) ii. Dietary intakes via food frequency questionnaire (FFQ) to allow exploration of relationship between diet, physical activity and obesity among PI adolescents; e.) Implement measurement and survey activities among a community-sample of Marshallese, Samoan and Tongan adolescents in Southern California; f.) Share study results with the CAC and community members to develop future research and intervention plans. The community participatory processes, along with protocols and instruments developed, will help ensure that the preliminary study results can be expanded upon in larger-scale assessment and intervention studies for the future.

描述（由申请人提供）：肥胖是人群中越来越重要的可改变的癌症相关危险因素，但对于不同种族人群预防和控制肥胖的方法知之甚少。太平洋岛民的肥胖和癌症发病率很高，这为干预措施的开发和测试提供了一个探索的机会，但他们仍然是不可见的，学术界对他们的研究不足。这项为期两年的探索性研究旨在了解南加州太平洋岛民（PI）青少年的肥胖相关影响。采用社区参与性研究（CBPR）方法，涉及四个社区机构和三所大学，该项目的目标是：1)在马绍尔群岛、萨摩亚和汤加青少年中测试各种数量和质量数据收集活动的可行性；2)估计肥胖和体育活动的点患病率。一个次要目的是探索这些群体的饮食摄入量分布；3)探讨影响该群体体育活动的易感因素、促进因素和增强因素。本研究的具体目的是：a.)在整个研究过程中召开社区咨询委员会（CAC）季度会议，向所有研究方法和社区外展活动的制定和实施提供信息；b。)针对来自三个太平洋岛民（马绍尔人、萨摩亚人和汤加人）的14-18岁青少年，设计并促进焦点小组，探讨对肥胖和体育活动的影响：一、开展体育活动的类型，包括地点、频率和目的；2。文化因素，包括身份认同、文化适应和文化信仰；3。为青少年提供有利机会和障碍的环境问题；四、个人因素，包括诱发性和强化性影响；c。)执行关于收集青少年肥胖和身体活动的客观测量方法的规程：i.身高和体重用于计算体重指数；2。用于计算进行中等和剧烈体力活动所需时间的加速度计数据；d。)设计和/或预测试一项调查工具，以评估：1 .对青少年身体活动的倾向和强化影响；（也列于b iv）通过食物频率问卷（FFQ）对PI青少年膳食摄入量进行调查，探讨饮食、身体活动与肥胖之间的关系；e)。在南加州的马绍尔人、萨摩亚人和汤加人青少年社区样本中开展测量和调查活动；f。)与CAC和社区成员分享研究结果，以制定未来的研究和干预计划。社区参与进程以及所制订的议定书和文书将有助于确保初步研究结果能够在今后更大规模的评估和干预研究中得到扩展。
