The association of positive affect and cardiovascular health in Hispanics/Latinos with chronic kidney disease: Results from the Hispanic Community Health Study/Study of Latinos (HCHS/SOL)

Abstract

The beneficial influence of positive affect (e.g., joy) remains unexplored in relation to heart health in adults with chronic kidney disease (CKD)—a population at increased risk for poor cardiovascular health (CVH). Therefore, we evaluated the association of positive affect and CVH in a diverse U.S. population of Hispanics/Latinos with CKD. We analyzed cross-sectional data of adults ages 18–74 enrolled between 2008 and 2011 in the Hispanic Community Health Study/Study of Latinos with prevalent CKD (N = 1712). Positively worded items from the Center for Epidemiologic Studies Depression Scale were used to create a composite positive affect score (0–6; higher scores indicate greater positive affect). Prevalent CKD was defined as estimated glomerular filtration 4 (vs. <4) ideal CVH indicators. Positive affect is associated with favorable CVH profiles in Hispanics/Latinos with CKD. Replication and prospective studies are needed to elucidate whether emotional well-being is a potential therapeutic target for intervention.
