A culturally competent behavioral weight loss program for adult Latinos with a BMI >30kg/m2

This study answers the question, “In Adult Hispanic BMI ≥ 30 (P), how does development of a weight loss program that utilizes Motivational Interviewing (I) compared to counseling and educational materials only (C) affect weight loss over the period of three months (T).” There are limited published systematic reviews and randomized control trials to evaluate the effectiveness of Motivational Interviewing (MI), in conjunction with diet and exercise to promote weight loss. Participants (n = 5) were Latino patients of a local community health care center who were overweight and medically at risk due to unhealthy lifestyles that were determined through a screening test.

The 4-week clinical pathway program used motivational interviewing in one-on-one sessions every other week, and implemented the “Your Heart, Your Life” curriculum the other weeks. One expected outcome included lower anthropometric measurement numbers of participants’ WL, BMI, WC, and BP. Another expected outcome was an increase in physical activity. Participants were also expected to earn a higher score on a post-test about nutrition and healthy living. A paired t-test and power analyses were used to assess its effectiveness.

Results indicated significant decrease in weight loss (t [5] = 3.68, p = .0211, Cohen’s dz=1.647). For heart healthy habits, there were significant increases all three categories: weight management (t [5] = - 3.36, p = .0211), cholesterol and fat (t [5] = - 3.138, p =.035, salt and sodium (t [5] = - 4.899, p = .008). In addition, there was an increase in knowledge (t [5] = - 4.000, p = .016). Every participant showed small gains. Future implications should include more participants, including males, a control group, innovative activities that help to motivate a community of learners and more flexibility in allotted time for interventions.
