title: The incidence of hip fracture in Uppsala County. Change of time trend in women.
abstract: The incidence of hip fracture in the population over 55 years in Uppsala County was calculated for the years 1980-1991. Specific incidences were calculated for each age, sex, and fracture type group. The time trend for the change in incidence was calculated for each group with linear regression using an exponential model. The overall incidence of hip fracture in both sexes over 55 years, standardized to the 1985 population, remained steady at 6/1000 during the study period. The incidence of cervical fractures in women showed a decrease in all age groups except over 85 years of age, where the incidence was constant. The corresponding incidence in men did not change over time. The incidence of trochanteric fracture increased in men 65-74 years of age and in women over 85 years of age. The incidence of trochanteric fracture in the rest of the age and sex groups remained unchanged.
