Culturally tailored aerobic exercise intervention for low-income Latinas

Purpose. To determine the efficacy of community-based, culturally tailored exercise intervention on the moderate and vigorous physical activity and physiologic outcomes of low-income Latino women (Latinas). Design. A randomized trial contrasted safety education to an aerobic dance intervention. Setting. Interventions were held in a "store-front" exercise site near a community clinic. Subjects. Sedentary low-income Latinas (N = 151; 18-55 years; 70% overweight/obese) were recruited. Retention was 91 % for follow-up measures. Intervention. Three sessions per week of supervised aerobic dance were provided for 6 months. Controls attended 18 safety education sessions over 6 months. Measures. Physical activity and aerobic fitness (VO2max) were primary outcomes. Results. Participants in the exercise group reported more vigorous exercise (p < .001) and walking (P = .005) at post-test than controls. Aerobic dance and unsupervised activity resulted in a five-fold greater increase in relative VO2max compared with controls (p < .001). Although exercise and fitness decreased at follow-up, vigorous exercise (p = .001) and relative VO2max (P < .001) remained higher in the exercise group, suggesting maintenance at I year. Conclusion. Culturally tailored aerobic dance can increase vigorous physical activity, possibly generalizing to walking, and the combination can improve cardiorespiratory fitness in low-income, overweight, sedentary Latinas.
