Center for the Study of Aging
The population of older adults continues to increase in the United States and around the world. Nations, states, localities, families, and older adults face many challenges and opportunities for the care of older adults. The RAND Center for the Study of Aging focuses on the social, economic, physical, and mental health and well-being of older adults across the world. The Center draws upon collective research expertise in demography, economics, medicine, psychology, public health, sociology, statistics, and survey to ensure long-term wellbeing across the lifespan, aging-in-place, healthy aging, financial security, and resilience of older adults.
Using the most rigorous quantitative and qualitative methods, RAND implements surveys, designs and evaluates interventions, conducts trials, and performs many types of innovative analytic methods for administrative, survey, contextual, and clinical data. Our work serves to produce important facts, identify causal relationships, and help the public- and private-sectors more effectively meet the needs of aging populations.

Enrolling in a higher-cost Medicare Advantage plan may not always get seniors better-quality health care. Plans that charged a higher monthly premium provided on average only slightly better care as compared to plans with no monthly premium.
Sleep problems may contribute to the disproportionate burden of Alzheimer's disease and related dementias among African Americans. In a study of predominantly African American older adults, lower quality sleep was associated with poorer cognitive function.
More fragmented sleep and longer periods of wakefulness after bedtime among a group of low-income African American adults were associated with lower cognitive function such as poor attention and visuospatial ability. Improving sleep may support prevention of Alzheimer's and related dementias.
