Effects of a Community Population Health Initiative on Blood Pressure Control in Latinos

BACKGROUND: Hypertension remains one of the most important, modifiable cardiovascular risk factors. Yet, the largest minority ethnic group (Hispanics/Latinos) often have different health outcomes and behavior, making hypertension management more difficult. We explored the effects of an American Heart Association–sponsored population health intervention aimed at modifying behavior of Latinos living in Texas. METHODS AND RESULTS: We enrolled 8071 patients, and 5714 (65.7%) completed the 90‐day program (58.5 years ±11.7; 59% female) from July 2016 to June 2018. Navigators identified patients with risk factors; initial and final blood pressure (BP) readings were performed in the physician's office; and interim home measurements were recorded telephonically. The intervention incorporated home BP monitoring, fitness and nutritional counseling, and regular follow‐up. Primary outcomes were change in systolic BP and health‐related quality of life. Using a univariate paired‐samples pre–post design, we found an average 5.5% (7.6‐mm Hg) improvement in systolic BP (139.1 versus 131.5, t=10.32, P<0.001). Quality of life measured by the European quality of life 5‐dimension visual analog scale improved from 0.79 to 0.82 (t=31.03, P<0.001). After multivariate regression analyses, improvements in quality of life and overall body mass index were significantly associated with reductions in systolic BP. CONCLUSIONS: A noninvasive, population health initiative that encourages routine engagement in patients’ own BP control was associated with improvements in systolic BP and quality of life for this largely Latino community.
