Beijing Healthy Aging Cohort Study (BHACS)
The BHACS is a large representative cohort of older people based on the general population of Beijing, China, and was designed to evaluate the prevalence, incidence, and natural history of cognitive decline, functional disability, and conventional vascular risk factors. BHACS was assembled from three existing cohorts, the Beijing Longitudinal Study of Aging (BLSA), the Cardiovascular and Cognitive Health Study in Middle-Aged and Elderly Residents of Beijing (CCHS-Beijing), and the Beijing Elderly Comprehensive Health Cohort Study (BECHCS). BHACS consists of a total population of 11,235 (6,281 in urban and 4,954 in rural areas) and an age range of 55 to 101 years, with a mean age of 70.35 years.
