The Comparative Study of Aging and Health in Asia (AHA) is a multi-country collaborative study of health among older Asians. The project uses existing longitudinal survey data to study health transitions in four Asian countries: Taiwan, the Philippines, Singapore and Indonesia.
The primary aims of the project are to:
(1) estimate population prevalence levels of various health outcomes, examine recent trends in prevalence levels within countries, determine individual-level transition rates in health status, and estimate active life expectancy;
(2) investigate the effects of socioeconomic status and family network characteristics and social support on health status transitions among older adults; and
(3) examine the individual and community-level determinants of health care utilization. Project collaborators include researchers from several of the study countries and the United States.
