Outcomes of a Culturally Tailored Partially Randomized Patient Preference Controlled Trial to Increase Physical Activity Among Low-Income Immigrant Latinas

Abstract

Introduction: Almost half (47.8%) of adult Latinas report they never engage in any leisure time physical activity (PA) which is an independent risk factor for the development of cardiovascular disease and other chronic illnesses. There is a pressing need to develop and test PA interventions among Latinas. Therefore, the purpose of this study was to evaluate the effects of a PA Intervention for Latinas, a culturally tailored, promotora-facilitated 12-week PA intervention. It was hypothesized that at the completion of the intervention, participants would have (a) higher daily PA levels; (b) improved aerobic fitness, muscle strength, and flexibility; and (c) lower body mass index and percentage of body fat. Methodology: A partially randomized patient preference trial design with lag group was used to test the intervention. Participants ( N = 76) attended twice weekly, low-impact aerobic/Latin dance PA classes taught by laywomen trained as promotoras. Results: Significant improvements were measured in aerobic fitness, muscle strength and flexibility, and daily PA levels ( p < .001). Sixty percent of the participants attended at least 60% of the PA sessions. Discussion: Findings suggest laywomen trained as promotoras can successfully facilitate the delivery of an intervention to increase PA among immigrant Latinas.
