Physical Activity Behavior Among Midlife South Asian Indian Immigrants

描述(申请人提供)：本项目的目的是调查中年南亚裔印度移民的生活方式、体力活动行为和体力活动的决定因素/相关因素，包括背景(文化适应、歧视和环境)和个人内部(自我效能)特征，这些移民有患心血管疾病、糖尿病和中心性肥胖的风险。本研究的目的是：(1)识别SAI移民的生活方式身体活动行为(休闲时间、职业和家庭)；(2)考察动态的个人特征(克服生活方式身体活动障碍的自我效能感)对SAI移民静态背景特征与生活方式身体活动行为之间关系的中介作用，并控制人口统计学、当前健康和社会支持。这项研究将针对2010年健康人目标，即将从事适度体力活动的亚洲成年人的比例从15%提高到30%，并由国家护理研究所强调消除健康差距。本研究以《SAI移民体力活动行为框架》(基于社会认知理论和生态模型)为指导，采用横断面、描述性、面对面访谈调查方法。纳入标准是出生在印度并移民到美国的SAI移民男性和女性，年龄在40岁到65岁之间，没有身体活动残疾。将通过SAI宗教机构、企业、报纸和口碑招募110名男性和女性样本。体力活动将通过自我报告(用于休闲和家庭的老年人社区健康活动模型计划[Champs]，用于职业的Tecumseh职业活动工具)以及在加速计上记录的每周中/高强度活动的步数和分钟数来评估。其他测量包括文化适应、歧视、环境(社区意识)、身体活动自我效能感、全球健康和流行病学研究中心抑郁量表(CES-D)得分。翻译措施的方法是委员会法，然后是重点小组。进行了大声思考的采访，以确保跨文化相关性。参与者将佩戴加速度计一周，并通过邮寄方式归还。将按性别获得所有衡量标准的描述性统计数据。数据分析将基于中介回归模型。该模型将用来解释自我效能感对背景特征(文化适应、歧视和环境)与体力活动之间关系的影响。研究结果将为制定与文化相关的战略，以增加体力活动和减少SAI中的健康差距提供指导。

DESCRIPTION (provided by applicant): The purpose of this project is to examine the lifestyle physical activity behaviors and the determinants/correlates of physical activity, including background (acculturation, discrimination and environment) and intrapersonal (self-efficacy) characteristics in midlife South Asian Indian (SAI) immigrants at risk for cardiovascular disease, diabetes, and central obesity. The study aims are to: (1) identify the lifestyle physical activity behavior (leisure time, occupational and household) of SAI immigrants; (2) examine the mediating effects of the dynamic intrapersonal characteristic (self-efficacy for overcoming barriers to lifestyle physical activity) on the relationship between the static background characteristics and lifestyle physical activity behavior in SAI immigrants, controlling for demographics, current health and social support. This study will address the Healthy People 2010 objective of increasing from 15% to 30% the percentage of Asian adults engaging in moderate physical activity and the National Institute of Nursing Research emphasis on the elimination of health disparities. Guided by the Physical Activity Behavior Framework for SAI Immigrants (based on social cognitive theory and the ecological model), the study design is a cross-sectional, descriptive, face-to-face interview survey. Inclusion criteria are SAI immigrant men and women born in India and immigrated to the U.S., 40 to 65 years of age, without physical activity disability. A sample of 110 men and women will be recruited through SAI religious institutions, businesses, newspapers, and word of mouth. Physical activity will be assessed by self-report (Community Healthy Activity Model Program for Seniors [CHAMPS] for leisure and household, Tecumseh Occupational Activity Instrument for occupational) and weekly steps and minutes in moderate/high-intensity activity registered on an accelerometer. Additional measures include acculturation, discrimination, environment (sense of community), self-efficacy for physical activity, global health, and Center for Epidemiological Studies-Depression scale (CES-D) scores. Translation of measures was done by the committee method, followed by focus groups. Think-aloud interviews were conducted to assure cross-cultural relevance. Participants will wear the accelerometer for one week and return it via mail. Descriptive statistics will be obtained for all measures and by gender. The data analysis will be based on the mediating regression model. The model will be used to explain the influence of self-efficacy on the relationship between background characteristics (acculturation, discrimination and environment) and physical activity. Findings will provide guidance in developing culturally relevant strategies for increasing physical activity and decreasing health disparities in SAIs.
