Dr.  Bandeen-Roche and colleagues found that 15% of older Americans are frail, and 45% are prefrail, in a large nationally representative study.

Dr. Frank Lin was awarded an NIH grant to develop and implement a community health worker model for providing hearing care to older adults.

Dr. Roth and colleagues showed that providing care to a family member with a chronic illness or disability may be associated with modest survival benefit for the caregivers in the REGARDS study.
