DESCRIPTION (provided by applicant): Latinos, the fastest growing segment of the US population, carry disproportionate rates of chronic illnesses such as obesity and diabetes and have the highest levels of physical inactivity Among Latino subgroups; Mexican American women experience some of the highest rates of obesity and sedentary lifestyles. Increasing daily moderate-intensity physical activity (PA) can prevent weight gain and improve overall physical and mental health. The aims are to: 1) identify and understand the factors that influence PA behavior for Mexican immigrant women in the Columbia MSA, SC; 2) develop and evaluate a culturally competent PA intervention that targets individual, family and community influences among Mexican immigrant women; and, 3) assess the feasibility and effectiveness of engaging community-based Lay health advisors (LHAs) as participatory researchers. In year 1 we propose to conduct formative assessments and develop the intervention in full partnership with a local Hispanic-serving organization and other community partners via a Program Advisory Team. Six LHAs will be recruited to participate in the planning and implementing the formative assessments. Data gathered from 12 focus groups and 25 in-depth interviews will inform the development of an intervention to promote moderate intensity PA among Mexican immigrant women. In year 2, each LHA will recruit 2 groups of 10 women (N=12 groups; N=120 women) to participate in the study. Each group will be randomly assigned to one of two conditions: an immediate intervention or a delayed intervention. Randomization will be balanced within LHA. Six groups will receive the immediate intervention and 6 groups will be measured as part of the delayed intervention. At the conclusion of the 6- month intervention, delayed intervention groups will receive the intervention (but no measurements). The intervention, based on Social Cognitive Theory and PEN-3 and Socio- ecological models, will be delivered by LHAs and emphasize meeting CDC-ACSM recommendations of 30 minutes of moderate-intensity PA on 5 or more days per week. Thus, in addition to individual behavior change, the intervention will target the social and cultural influences within the Latino family and community. Standardized assessments will occur at baseline and 6-months follow-up and PA will be assessed using accelerometers. We hypothesize that compared to participants randomized to the delayed intervention, immediate intervention participants will show greater increases in minutes per day moderate intensity physical activity (primary outcome), show greater increases in perceived social support and self- efficacy for physical activity and less weight gain (secondary outcomes). PUBLIC HEALTH RELEVANCE This proposal will lay the foundation for rigorous evaluation of the incorporation of lay health advisors in a participatory research approach to affecting physical activity among Mexican immigrant women. The study will provide preliminary evidence for the feasibility of this approach, including logistical issues, levels of community participation, potential effect sizes for behavioral outcomes, and the cultural suitability and reliability of measures. These preliminary findings will be used to develop a large-scale, community-based trial of the participatory, lay health advisor approach to promoting physical activity in Latino communities and assisting in the reduction of health disparities.

描述（由申请人提供）：拉丁美洲人是美国人口中增长最快的部分，其慢性病的比例不成比例，例如肥胖和糖尿病，在拉丁裔亚组中具有最高水平的身体不活跃。墨西哥裔美国妇女经历了一些肥胖和久坐的生活方式的最高速度。增加每日强度体育锻炼（PA）可以防止体重增加并改善整体身心健康。目的是：1）确定并理解影响哥伦比亚MSA墨西哥移民妇女的PA行为的因素； 2）开发和评估具有针对墨西哥移民妇女个人，家庭和社区影响的具有文化能力的PA干预； 3）评估参与性研究人员的参与性外行健康顾问（LHAS）的可行性和有效性。在第一年，我们建议通过计划咨询团队与当地的西班牙裔服务组织和其他社区合作伙伴进行完整合作进行形成性评估。将招募六个LHA参加计划和实施形成性评估。从12个焦点小组和25个深入的访谈中收集的数据将为促进墨西哥移民妇女中等强度PA的干预发展提供信息。在第2年，每个LHA将招募2组10名女性（n = 12组； n = 120名女性）参加研究。每个组将被随机分配给两个条件之一：立即干预或延迟干预。随机化将在LHA内平衡。六组将立即进行干预，将进行6组，作为延迟干预的一部分。在6个月干预的结论结束时，延迟干预组将接受干预（但没有测量）。根据社会认知理论和第3条和社会生态模型，该干预措施将由LHA提供，并强调每周5天或更长时间以30分钟的中度强度PA来满足CDC-ACSM建议。因此，除了个人行为改变外，干预还将针对拉丁裔家庭和社区内的社会和文化影响。标准化评估将在基线和6个月的随访中进行，PA将使用加速度计进行评估。我们假设，与随机分配到延迟干预措施的参与者相比，即时干预参与者每天每天的数分钟中等强度的体育活动（主要结果）显示出更大（次要结果）。公共卫生相关性该提案将为对外行健康顾问的纳入纳入墨西哥移民妇女的体育锻炼的参与性研究方法的认真评估奠定基础。该研究将为这种方法的可行性提供初步证据，包括后勤问题，社区参与水平，行为结果的潜在效果大小以及措施的文化适应性和可靠性。这些初步发现将用于开发一项基于社区的大规模，基于社区的试验，以促进拉丁裔社区的体育活动并协助减少健康差异。
