Overweight/obesity and physical inactivity are two significant predictors of illness and death from cardiovascular (heart) disease (CVD)in Latina adults. These risk factors may be reduced or eliminated through prevention efforts that focus on heart-healthy diets, weight reduction, and PA. The purpose of this study is to compare the effects of a 6-month community-based lifestyle behavior intervention (LSBI) conducted by promotoras and a control condition (disaster preparedness and home safety program) on BMI (primary outcome) and selected physiologic outcomes (secondary outcomes i.e., physical activity, blood pressure, measures of cholesterol, fasting blood sugar, waist circumference, self-reported lifestyle behaviors - diet and physical activity) of Latinas who are overweight/obese. Exploratory analysis will examine the relationship between theoretical variables (stage of change and support for nutrition and physical activity), the LSBI and selected outcomes (BMI, self-reported lifestyle behaviors). The LSBI includes group education and individual teaching and coaching.
