The Costa Rican Longevity and Healthy Aging Study (CRELES) is a nationally representative longitudinal survey of health and lifecourse experiences of 2,827 Costa Ricans ages 60 and over in 2005. Baseline household interviews were conducted between November 2004 and September 2006, with 2-year follow-up interviews.

The main study objective was to determine the length and quality of life, and its contributing factors in the elderly of Costa Rica.
CRELES uses public data files containing information on a broad range of topics including self-reported physical health, psychological health, living conditions, health behaviours, health care utilization, social support, and socioeconomic status. Objective health indicators include anthropometrics, observed mobility, and biomarkers from fasting blood and overnight urine. Mortality events are tracked and conditions surrounding death are measured in a surviving family interview (longitudinal follow-up data are not yet publicly available).
