A Community Health Worker-Delivered Intervention in African American Women with Type 2 Diabetes: A 12-Month Randomized Trial.
OBJECTIVE To evaluate the effectiveness of a community health worker (CHW)-delivered lifestyle intervention for African American women with type 2 diabetes . METHODS Participants were r and omized to either 16 phone-based lifestyle intervention sessions aim ed at making small changes in their diet and activity or 16 educational mailings sent across 12 months . Main outcomes included glycosylated hemoglobin ( HbA1c ) , blood pressure ( BP ) , and weight ( kg ) changes . RESULTS Two hundred middle-aged ( mean = 53 ± 10.24 years ) , rural , African American women with moderate obesity ( mean BMI = 37.7 ± 8.02 ) and type 2 diabetes ( mean HbA1c = 9.1 ± 1.83 ) were enrolled . At 12 months , the intervention group exhibited no significant differences in HbA1c ( -0.29 ± 1.84 vs. + 0.005 ± 1.61 ; P = 0.789 ) or BP ( -1.01 ± 20.46/+0.66 ± 13.24 vs. + 0.22 ± 25.33/-2.87 ± 1.52 ; P = 0.100 ) but did exhibit greater weight loss ( -1.35 ± 6.22 vs. -0.39 ± 4.57 kg , respectively ; P = 0.046 ) compared with controls . Exploratory post hoc analyses revealed that participants not using insulin had significantly greater reductions in HbA1c ( -0.70 ± 1.86 vs. + 0.07 ± 2.01 ; P = 0.000 ) , diastolic BP ( -5.17 ± 14.16 vs. -3.40 ± 14.72 mmHg ; P = 0.035 ) , and weight ( -2.36 ± 6.59 vs. -1.64 ± 4.36 kg ; P = 0.003 ) compared to controls not on insulin . CONCLUSIONS A phone-based CHW intervention result ed in no significant improvements in HbA1c or BP but did demonstrate modest improvements in weight . Women not using insulin showed significant improvements in all primary outcomes
