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. In this study, we explore the effects of one large community-based intervention.Methods and Results: The American Heart Association sponsored an initiative targeted towards Hispanics called the Check.Change.Control program in San Antonio Texas (7th largest city in the U.S.; nearly 56% Hispanic population). The initiative was funded by a gift from the Max and Minnie Tomerlin Voelcker Fund. There have been 5,800 patients enrolled to-date, and 4,598 have completed the intervention from July 2016 to December 2017. Three ambulatory clinics provided geographic distribution across the region (Figure 1). Patient navigators helped to enroll and follow-up with hypertensive patients (>130 mmHg) over a 90-day period. The first and final BP readings were performed in the physician’s office, and 4 interim measurements were recorded telephonically by provided cuffs for a total of 6 BP readings. The intervention consisted of self-engagement in home BP monitoring, fitness and nutritional counseling sessions, and provider coaching and follow-up. Primary outcomes included BP systolic change between first and last reading, and health-related quality of life assessment. Average patient age was 57 years (±11.7) and 59% were female. Using univariate paired samples pre-post design, we found an average of 6 mmHg reduction in systolic BP across the sample (139 vs. 133, t=10.32, p<.001). Quality of life (EQ- 5D VAS) indicated a mean change after intervention from .80 to .82 (t=31.03, p<.001).Conclusions: Community-based interventions which extends hypertension management outside of the provider’s office can be effective at patient self-engagement and BP reductions for Latino populations.Figure 1: Geospatial Analysis of Study Participants
