Costa Rican Longevity and Healthy Aging Study

Abstract

The Costa Rican Longevity and Healthy Aging Study (CRELES, or Costa Rica Estudio de Longevidad y Envejecimiento Saludable) is a set of nationally representative longitudinal surveys of health and life-course experiences of older Costa Ricans, conducted by the University of Costa Rica’s Centro Centroamericano de Población in collaboration with the University of California at Berkeley. CRELES is part of the growing set of Health and Retirement Surveys being conducted around the world (See “Health and Retirement Study”). Costa Rica is of particular interest to study given its high longevity: life expectancy is greater than that of the United States, despite being a middle-income country.

CRELES comprises five waves of data from two birth cohort panels (See “Cross-Sectional Research/Panel Studies (Longitudinal Studies)”). The original CRELES Pre-1945 cohort is a sample of more than 2,800 Costa Rica residents born in 1945 or before. There are three waves of interviews for this panel conducted mainly in 2005, 2007, and 2009. Wellcome Trust funded this panel (Grant N. 072406). The CRELES 1945–1955 Retirement Cohort (RC) is a sample of about 2800 Costa Rica residents born in 1945–1955 plus 1400 of their spouses, interviewed mainly in 2011 and 2013 (waves 4 and 5). The US National Institute on Aging (grant R01AG031716) funded this panel through the University of California, Berkeley.

CRELES data are well-suited for studying longevity and health determinants, relationships between socioeconomic status and health, stress and health, patterns of health behaviors, and prospective mortality.
