Hip fracture incidence in Lund, Sweden, 1966-1986

Abstract

The hip fracture incidence in the city of Lund and its rural surroundings was studied for the years 1966, 1972, 1981, and 1986. The total incidence increased from 3.3 to 5.1 per 1,000 inhabitants above 50 years of age. For persons more than 80 years old, the incidence almost doubled from 13.2 to 25.5, i.e., this group represented the entire increase in incidence. In the urban population, men with cervical fractures had an increased incidence. A smaller increase in incidence for both men and women was found in the rural area. Compared with larger cities, the incidence increase in the urban population in Lund was lower over time, but in 1986 the figures were comparable to those in Gothenburg in 1981. The total incidence in the mixed urban and rural population was as of 1981 higher than in Denmark and Finland, but lower than in Norway. If the incidence in the elderly continues to increase to 1995, there will be three times as many hip fractures as there were in 1966.
