In 1,076 women who had been interviewed from 1970 to 1976 with regard to previous fracture and disease, all fragility fractures that occurred from 1975 to 1985 were recorded. Hip and vertebral fractures were good predictors of future fragility fractures but mainly in younger women (less than 70 years) and this was also the case for fracture of the distal end of the forearm in the age group 40-59. Later in life, falling tendency became the important predictor.
