From 1970 to 1986 a total of 4578 hip fractures were registered in persons > or = 40 years in a Danish urban municipality. During that period, the annual number almost tripled. The statistical analysis revealed an increase in the age-specific incidence for both females and males (p < 0.0001). Furthermore, the number of fractures increased due to demographic aging. The overall incidence for individuals > or = 40 years increased 9-10% annually; from 2.1 to 5.4 per 1.000 females, and from 0.9 to 2.1 per 1.000 males. The female:male ratio was 2.8 without changes over time. If the observed increase in incidence is extrapolated to the next 17 years, a doubling of the annual number of fractures is predicted by the year 2002, whereas an unchanged incidence would result in a 20% increase in number.
1970年至1986年期间，丹麦一个城市辖区内共登记了4578例40岁及以上人群的髋部骨折病例。在此期间，年病例数几乎增至原来的三倍。统计分析显示，女性和男性的年龄别发病率均有所上升（p < 0.0001）。此外，由于人口老龄化，骨折病例数有所增加。40岁及以上人群的总体发病率每年上升9%至10%；每1000名女性中从2.1例增至5.4例，每1000名男性中从0.9例增至2.1例。女性与男性的比例为2.8，且未随时间变化。如果将观察到的发病率上升趋势推算至未来17年，预计到2002年骨折年病例数将翻倍，而发病率不变则病例数将增加20%。
