In cooperation with the Sealy Center on Aging a number of core faculty, postdoctoral fellows, and graduate students are involved in a wide range of research activities focusing on the older adult population. These studies include a population based longitudinal investigation of Mexican American older adults, the Hispanic Established Populations Epidemiological Study of the Elderly. This is the largest ongoing investigation in the U.S. of changes in functional status, disability, psychological and behavioral outcomes in Mexican American older adults. Other research activities focus on the examination of the enabling-disabling process in older adults and on exploring the impact of changes in reimbursement and service delivery on functional status, length of hospital stay, living setting following hospitalization and mortality. The goal of these investigations is to prevent or reduce disability and enhance the quality of life and functional independence of older adults.
