NIA Demography Centers
Conducting new research and training in aging
Brian E. McGarry, Nicole Maestas, and David C. Grabowski concluded, in an article published in the journal Health Affairs, found that inefficiencies in an internet-based Medicare tool called "The Plan Finder" used by the Centers for Medicare and Medicaid Services (CMS) to help beneficiaries identify a preferred plan, may be resulting in consumers not choosing the lowest cost plans that fit their needs.
CALERIE (Comprehensive Assessment of the Long-term Effects of Reducing Intake of Energy) at Duke University has collected a trove of biosamples and data. NIA continues to fund research opportunities using CALERIE data. Caloric restriction (CR) has been shown in laboratory animal models to increase life span. CALERIE was the first study to focus on the effects of sustained CR in humans.
The National Archive of Computerized Data on Aging, funded by the NIA and housed at Michigan, acquires and disseminates datasets relevant to gerontological research - processing these data as needed to promote their effective research use. With thousands of datasets, NACDA offers rich opportunities for secondary analyses of data addressing a wide scope of issues on aging.
The pioneering Future Elderly Model (FEM) allows microsimulation of future trends in the health, functional status, health spending, and earnings for people over age 50. Led by USC, the NIA-supported FEM has collaborators at Harvard, Stanford, RAND, Michigan, and Penn, and has been adapted for use in countries across the globe.
Using NHATS data, 2011-2015, Vicki Freedman, Judith Kasper, Brenda Spillman, and Brenda Plassman analyze the prevalence of probable dementia over this period among Americans 70 and older, finding declines that are concentrated among women, non-Hispanic whites and blacks, and those with no risk factors.
