Overweight/obesity and physical inactivity are two significant predictors of morbidity and mortality from cardiovascular disease (CVD) and other chronic diseases (e.g., diabetes) in Latina adults. These risk factors are modifiable and amenable to lifestyle behavior prevention efforts that focus on promoting a healthy diet and increasing physical activity (PA). The overall goal of this experimental study is to evaluate the effects of a 6-month community-based healthy lifestyle behavior intervention (LSBI) provided by promotoras, designed to improve diet and PA of overweight/obese, middle-age Latino women who are predominantly Spanish-speaking immigrants. The study builds upon formative and feasibility studies implemented using community-based participatory research methods and materials developed in a NHLBI CVD prevention initiative for Latinos. Participants (N=240), ranging in age from 35-64, will be randomly assigned to either the LSBI or a comparable length control condition (disaster preparedness and home safety program). The culturally sensitive LSBI includes 2 months of small group education (based upon Su Corazón, Su Vida) and a walking club, followed by 4 months of individualized teaching and counseling (ITC). Strategies to promote behavior change, support healthy nutrition and weight loss, and increase PA will be incorporated into the ITC. Data will be collected at baseline, post intervention (6 months after intervention initiation) and at a 3- month follow-up using a combination of clinical and behavioral measures. The primary outcome to be evaluated is change in body mass index (BMI). Secondary outcomes include objective measures of PA (accelerometer readings), blood pressure, cholesterol, blood sugar, waist circumference and self-reported lifestyle behaviors. Selected mediating (stage of change) and moderating variables (social support), derived from the transtheoretical model of behavior change and social ecological model, will be examined in relation to the intervention and program outcomes. Findings will contribute to knowledge about effective communitybased CVD prevention for Latinas involving lifestyle intervention delivered at a grassroots level by promotoras, outside of clinical settings. Understanding also will be enhanced about the influence of interpersonal and environmental factors on adoption of healthy lifestyle behaviors of Latinas.

超重/肥胖和身体上的不活跃是拉丁裔成年人中心血管疾病（CVD）和其他慢性疾病（例如糖尿病）的发病率和死亡率的两个重要预测指标。这些危险因素是可修改的，并且可以预防生活方式行为的努力，该工作着重于促进健康的饮食和增加体育锻炼（PA）。这项实验研究的总体目的是评估由促进者提供的6个月基于社区的健康生活方式干预（LSBI）的影响，旨在改善饮食和PA的超重/肥胖，中年拉丁裔妇女，这些妇女主要是讲西班牙语的移民。这项研究基于使用基于社区的参与研究方法和材料在NHLBI CVD预防计划中开发的材料进行的形成性和可行性研究。参与者（n = 240）的年龄为35-64岁，将随机分配给LSBI或可比的长度控制条件（灾难准备和家庭安全计划）。对文化敏感的LSBI包括2个月的小组教育（基于Sucorazón，Su Vida）和一个步行俱乐部，随后是4个月的个性化教学和咨询（ITC）。促进行为改变，支持健康的营养和体重减轻以及增加PA的策略将纳入ITC。数据将在基线，干预后（干预开始后6个月）以及在3个月后使用临床和行为测量的组合收集数据。要评估的主要结果在体重指数（BMI）中发生了变化。次要结果包括对PA的客观测量（加速度计读数），血压，胆固醇，血糖，腰围和自我报告的生活方式行为。将根据干预和计划结果研究，将检查选定的中介（变化阶段）和调节变量（社会支持）（社会支持）（社会支持）。调查结果将有助于了解有效的基于社区的CVD预防涉及涉及临床环境以外的促销员在基层上提供生活方式干预的拉丁裔。关于人际和环境因素对采用拉丁裔健康生活方式行为的影响，也将增强理解。
