To conduct a cross-sectional and follow-up preliminary intervention study in order to describe and analyze the CVD-related diet, physical activity, and exercise practices predictors in 221 Mexican and Central American women recruited from six counties in Northern California. Face-to-face interviews were conducted with Mexican American and Central American women (ages 40-75) who had at least one risk factor for CVD to answer the following questions: What were the CVD-related risk factors, dietary practices, physical activity, and exercise behaviors in Mexican and Central American women who were 40 to 75 years and who had at least one risk factor for CVD? What was the relationship between predictor variables (resources, situational, personal, and demographic factors) with CVD-related diet practices, physical activity, and exercise behaviors (outcome variables)?, and what were the short and intermediate-term effects of a cardiovascular nursing intervention on diet, physical activity, and exercise? A sample of 221 women was targeted. Data were collected during the first two years of the project to provide substantial research-based information to develop a cardiovascular nursing intervention to support Latina women efforts to promote heart health and prevent CVD. Data were analyzed during the third year and the cardiovascular nursing intervention was developed to determine the short (3 months) and intermediate-term (6 months) effects in the outcome variables. A randomly selected sample of 60 women from the same cohort was randomly assigned to the developed intervention group (n=30 in each group) and to a delayed-intervention control group.
