abstract="Subsequent hip fracture among the 368 Longitudinal Study on Aging respondents who fractured their hips from 1984 through 1991 was prospectively examined. Case-by-case review of the billing records indicated that 27 subsequent hip fractures occurred, for a rate of 1 every 33.8 person-years. Multivariable proportional hazard regression revealed that increased risks of subsequent hip fracture were associated with poor perceived health status and dizziness.",
