Two studies focussed on reducing cardiovascular disease(CVD) risk factors for Hispanics. One study showed a statistically significant (p < 0.001) change in diastolic blood pressure in the CHW arm compared to those receiving basic educational materials [23]. Trends towards significance were found for waist circumference (p = 0.09), non-HDL cholesterol (p = 0.10), and HbA1c (p = 0.09), favouring the CHW intervention arm. No significant differences were reported for BMI, weight, blood glucose or three other cholesterol measures. The ER for this study was 0.29. The second study reported a statistically significant higher reduction in systolic blood pressure in the CHW arm compared to the usual care arm [19]. A trend towards significance (p = 0.051) was found for 10-year CHD risk. The other clinical measures (including BMI, cholesterol,
and two other blood pressure measures) did not show significant changes. We found an ER of 0.22 for this study. In a study on reducing diabetes risk factors among African Americans, no statistically significant differences were found for HbA1c or five other clinical measures
. As a result, the ER was 0.00. The mean ER for the outcome category “health outcomes” was 0.17.
