The Costa Rican Longevity and Healthy Aging Study (CRELES)

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 lifecourse experiences of older Costa Ricans. CRELES is part of the growing set of Health and Retirement Surveys being conducted around the world. 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 with about one-fifth the per capita income and one-tenth the per capita health spending. CRELES is now composed of multiple waves of data from two birth cohorts.

哥斯达黎加长寿与健康老龄化研究（Costa Rican Longevity and Healthy Aging Study，缩写CRELES，又名西班牙语原称"Costa Rica Estudio de Longevidad y Envejecimiento Saludable"）是针对哥斯达黎加老年人群健康与生命历程经历开展的全国代表性纵向调查集合。CRELES属于全球范围内不断扩充的健康与退休研究（Health and Retirement Surveys）系列之一。鉴于哥斯达黎加的高长寿水平，其成为长寿相关研究的重点样本：尽管该国为中等收入国家，人均收入仅约为美国的五分之一、人均医疗支出仅为美国的十分之一，但其国民预期寿命却高于美国。目前，CRELES包含来自两个出生队列的多轮调查数据。
