Time trends in incidence rates of first hip fracture in the Uppsala Health Care Region, Sweden, 1965-1983.
Time trends from 1965 through 1983 for age-specific and age-standardized rates of first hospital admission for a proximal femur fracture were studied in the Uppsala Health Care Region, Sweden, using a centralized register for inpatient care. During the 19-year study period, 29,277 hospital admissions for a first hip fracture were recorded in this population of about 1.5 million persons. The total number of first hip fracture admissions per year increased for both sexes. Age-standardized admission rates for both cervical and trochanteric fractures increased in men (average change per year of 1.8% and 2.6%, respectively) in contrast to the decreased admission rate for cervical fractures (-1.6% per year) and a stable rate for trochanteric fractures (0.4% per year) in women. The cumulative rate of cervical or trochanteric fracture at ages 30-79 years increased 46% in men (from 42/1,000 population in 1965 to 61.5/1,000 population in 1983) in contrast to a 24% decrease in women (from 134/1,000 population in 1965 to 101.5/1,000 population in 1983). The female:male ratio of age-standardized incidence rates decreased for both types of fracture during the study period. This finding of stable or decreasing rates of hip fracture in women contrasts with the findings of most previous studies.
