Results of the Heart Healthy and Ethnically Relevant Lifestyle trial: a cardiovascular risk reduction intervention for African American women attending community health centers.
OBJECTIVES We evaluated a theory-based lifestyle intervention targeting physical activity and dietary fat intake among African American women at high risk for cardiovascular disease . METHODS The Heart Healthy and Ethnically Relevant Lifestyle trial ( 2005 - 2008 ) r and omly assigned 266 low-income African American women aged 35 years and older who were patients of South Carolina community health care centers into comprehensive or st and ard care interventions . Comprehensive participants received st and ard care ( stage-matched provider counseling and assisted goal setting ) plus 12 months of telephone counseling and tailored newsletters . Primary outcomes were 6- and 12-month self-reported physical activity and dietary fat intake . RESULTS Comprehensive participants were more likely than were st and ard care participants to decrease total physical activity ( odds ratio [ OR ] = 3.13 ; 95 % confidence interval [ CI ] = 1.18 , 8.25 ) and increase leisure-time physical activity ( OR = 3.82 ; 95 % CI = 1.41 , 10.3 ) at 6 months ( no 12-month differences ) . Mean reductions in Dietary Risk Assessment score occurred in both groups but were greater among comprehensive participants than among st and ard care participants ( 6 months , -8.50 vs -5.34 ; 12 months , -7.16 vs -3.37 ; P < .001 ) . CONCLUSIONS The comprehensive intervention improved women 's leisure-time physical activity and dietary fat intake , highlighting a replicable model to help primary care providers implement lifestyle counseling
