Reduction in Cardiovascular Risk Among Latino Participants in a Community-Based Intervention Linked With Clinical Care

Abstract

Introduction: Community Heart Health Actions for Latinos at Risk is a community health worker-led cardiovascular disease risk reduction program targeting low-income urban Latinos. The impact of community programs linked with clinical care has not been well characterized.

Methods: Community Heart Health Actions for Latinos at Risk provided 12 weeks of lifestyle education. Changes in risk factors were assessed before and after completion. Univariate, bivariate, and multivariate analyses were used to determine factors associated with changes in risk factors.

Results: From 2009 to 2013, a total of 1,099 participants were recruited and 768 had risk factors measured at baseline and 12 weeks. All analyses were performed in 2016. In participants with abnormal baseline risk factors, significant (all p<0.001) median reductions in systolic blood pressure (-11 mmHg, n=244); low-density lipoprotein cholesterol (-14 mg/dL, n=201); glucose (-8 mg/dL, n=454); triglycerides (-57 mg/dL, n=242); and Framingham risk score (-2.3%, n=301) were observed. Program completion (eight of 12 classes) was associated with the reduction in low-density lipoprotein cholesterol (p=0.03) and systolic blood pressure (p=0.01). After adjustment, low-density lipoprotein cholesterol reduction was greatest in participants newly prescribed lipid-lowering drugs (-30%, 95% CI= -48, -15).

Conclusions: A community health worker-led intervention lowered cardiovascular disease risk among vulnerable Latinos. Integration with primary care services was an essential program component.
