Evidence-based intervention program for reducing obesity among African-American women in Southern California

Objective: This study evaluated the effectiveness of group motivational education and empowerment program using evidence-based approaches for obesity and weight loss management for African-American Women. Design: This study employed a quasi-experimental time series design based on the theoretical frameworks of the Empowerment and Health Belief models. Sample: Twenty-eight African-American Women were recruited into culturally appropriate and responsive weight-loss management program. Measurements: The weight management programs consisted of nutrition education, physical activities, and focus-group sessions. Measurements included analysis of blood samples for cholesterol, waistline, body mass index, and exercise time. Statistical analysis compared program outcomes at baseline and 3-month intervals for 1 year. Intervention: Participants were educated on healthy food choices and physical activities based on National Institutes of Health's food guidelines. Results: The results showed that 90% of participants lost 20 pounds or more and 82% had 6 inches or more waist circumference reductions. Additionally, cholesterol reductions and improved nutrition knowledge and exercises were significant. Conclusions: We developed an evidence-based and culturally appropriate intervention for weight-loss management among African-American women. Acceptance of personal responsibility to modify behaviors, knowledge of good nutrition, and engagement in physical activities were positive and effective health behavioral changes in promoting health and weight-loss management for this population.
