Hip fractures:

Are a major threat to survival and a leading cause of disability worldwide in men and women over 65.

Aging of the population worldwide means the number of hip fractures is expected to double by 2050.

    • Increased incidence rates among men.

    • 1/3 of men with a hip fracture will not survive 1 year after their fracture.

Conducted 9 longitudinal cohort studies progressing from observational to interventional with continuous NIA funding since 1983.
Enrolled and followed more than 4,000 hip fracture patients admitted to 27 Baltimore-area hospitals.
International reputation to successfully conduct longitudinal research studies with frail older populations.
Key findings from the BHS have served as the impetus for intervention trials and drug development in hip fracture patients.
Over 225 publications and numerous presentations.
