Overweight and obese African American women tend to suffer most from the impacts of diseases, health disparities, disabilities, and decreased qualities of life (Sutton et al., 2016). Most weight loss programs are not culturally specific, despite the benefits of dietary changes and increased physical activity for all groups. The purpose of this EBP project was to implement a provider-led program including lifestyle, dietary, and activity components to decrease weight, BMI, waist circumference and blood pressure in African American women. The Iowa Model of Evidence-Based Practice to promote quality care was used to guide the EBP project, aimed to address obesity in a family practice located in an underserved community in Northwest Indiana. Fifteen overweight or obese African American women were identified as they presented for routine medical care. The intervention for this EBP project consisted of a 12-week provider-led weight loss program that included lifestyle changes that targeted nutrition, physical activity, behavioral self-management, and follow-up appointments. A one-way repeated measure ANOVA were calculated comparing means of weight, BMI, waist circumference and secondary measure blood pressures at four different intervals: baseline, 4, 8 and 12 weeks. Significant effect was found at baseline weight to 12 weeks weight (F(3,42)=5.77, p <.05), baseline BMI to 12 weeks BMI (F(3,42)= 5.65, p <.05, baseline WC to week 8 WC and baseline WC to 12 weeks WC (F(3,42) =6.868, p <.05). A paired-samples t test were calculated to further compare the mean at six different intervals. There were significant difference at baseline weight to week 12 weight (t (14)= 2.54, p<.0083), baseline BMI to 12-week BMI (t(14)=3.216, p <.0083), baseline WC to week 8 WC (t(14)=3.076, p <.0083) and baseline WC to 12-weeks WC (t(14)=4.305, p < .0083). Secondary outcomes: no significant difference existed for systolic blood pressure (F(3,42)=.021, p >.05 or for diastolic blood pressure (F(3,42)=.210, p >.05). These findings demonstrated that a provider-led intervention improved weight reduction for African American women.
