Aging in Taiwan:

Two Studies

In 1989, the Taiwan Longitudinal Study of Aging (TLSA) began collecting health, social, and economic data from a cohort of Taiwanese participants over the age of 60. TLSA captured updated responses from the cohort by surveying them every three to four years, and study investigators have also added several refresher cohorts in order to accurately represent the middle-aged and elderly populations. TLSA’s primary motivations were to: interrogate the potential health impacts of an individual’s socioeconomic status; gauge the overall well-being and health status of the middle-aged and elderly Taiwanese populations; and, ascertain the social and health needs of these populations for the purpose of creating effective population policies. 

The Social Environment and Biomarkers of Aging Study (SEBAS) was a joint undertaking between the Taiwan Health Promotion Administration, Ministry of Health and Welfare, and Princeton and Georgetown Universities. SEBAS extends the Taiwan Longitudinal Study of Aging (TLSA) and seeks to answer the following questions: “(1) what are the reciprocal relationships among health, the social environment, and exposure to challenge and (2) what can be learned from biomarkers about the pathways and mechanisms through which those relationships operate.” With the addition of longitudinal data, the goals of the project have expanded to understanding the antecedents, correlates, and consequences of levels and changes in biological measures, health and survival.
