Ethnic differences in blood pressure control among men at Veterans Affairs clinics and other health care sites
2005
Background Differential access to health care may contribute to lower blood pressure (BP) control rates to under 140/90 mm Hg in African American compared with white hypertensive patients, especially men (26.5% vs 36.5% of all hypertensive patients in the National Health and Nutrition Examination Survey 1999-2000). The Department of Veterans Affairs (VA) system, which provides access to health care and medications across ethnic and economic boundaries, may reduce disparities in BP control. Methods To test this hypothesis, BP treatment and control groups were compared between African American (VA, n = 4379; non-VA, n = 2754) and white (VA, n = 7987; non-VA, n = 4980) hypertensive men. Results In both groups, whites were older than African Americans ( P P P P = .12). In contrast, BP control was higher among African American hypertensive men at VA (49.4%) compared with non-VA (44.0%) settings ( P P = .18) and more prescriptions at non-VA sites than did whites ( P P P Conclusions The ethnic disparity in BP control between African Americans and whites was approximately 40% less at VA than at non-VA health care sites (6.2% vs 10.2%; P
