Abstract

Background: 2014 hypertension guidelines raised treatment goals in older adults. The objective was to examine changes in blood pressure (BP) control (<140/90 mm Hg) from 2011-2013 to 2016-2017 among Black and white older adults with treated hypertension. Methods: Participants were 1,600 white and 650 Black adults aged 71-90 years in the Atherosclerosis Risk in Communities (ARIC) Study with treated hypertension in 2011-2013 (baseline) who had BP measured in 2016-2017 (follow-up). Predictors of changes in BP control were examined by race. Results: BP was controlled among 75.3% of white and 65.7% of Black participants at baseline and 59.0% of white and 56.5% of Black participants at follow-up. Among those with baseline BP control, risk factors for incident uncontrolled BP included age (relative risk [RR] 1.15 per 5 years, 95% confidence interval [CI] 1.07-1.25), female sex (RR 1.36, 95% CI 1.16-1.60), and chronic kidney disease (RR 1.19, 95% CI 1.01-1.40) among white participants, and hypertension duration (RR 1.14 per 5 years, 95% CI 1.03-1.27) and diabetes (RR 1.48, 95% CI 1.15-1.91) among Black participants. Among those with uncontrolled BP at baseline, white females vs. males (RR 0.60, 95% CI 0.46-0.78) and Black participants with chronic kidney disease vs. without (RR 0.58, 95% CI 0.36-0.93) were less likely to have incident controlled BP. Conclusions: BP control decreased among white and Black older adults. Black individuals with diabetes or chronic kidney disease were less likely to have controlled BP at follow-up. Higher treatment goals may have contributed to these findings and unintended differences by race.
