BRIGHTEN Heart: Design and baseline characteristics of a randomized controlled trial for minority older adults with depression and cardiometabolic syndrome.

ABSTRACT

OBJECTIVES: African American and Hispanic elderly are at elevated risk of both depression and cardiovascular disease, relative to non-Hispanic whites. Effective interventions are therefore needed to address depressive symptoms and to reduce these disparities. BRIGHTEN Heart was a behavioral randomized controlled trial to test the efficacy of a virtual team intervention in reducing depressive symptoms in minority elderly as measured by the 9-item Patient Health Questionnaire (PHQ9). STUDY DESIGN: 250 African American and Hispanic adults, age ≥60 years, with comorbid depression and overweight/obesity were randomized. Participants randomized to the Intervention condition received a social work evaluation, team-based electronic consultation, case management, and psychotherapy over a 12 month period. Control participants were enrolled in a membership program that provided health classes and other services to support chronic disease self-management. Blinded research assistants completed assessments at baseline, and 6 and 12 months postrandomization. RESULTS: The study population was characterized by low socioeconomic status, with 81.4% having a household income of less than $20,000. Although median depression scores were in the mild range, 25% of participants had scores showing moderate to severe depression at baseline. 75% of participants had four or more chronic conditions. Significant demographic and clinical differences were observed between the African American and Hispanic populations. CONCLUSIONS: BRIGHTEN Heart was designed to rigorously test the efficacy of a multi-level intervention to reduce comorbid depressive symptoms and cardiovascular risk in minority elderly. Investigators successfully recruited a cohort well suited to testing the study hypothesis.
