Hip fracture incidence rates are high, and increase with increasing age. Previous studies have predicted a continued increase in both crude and age-standardized rates.
We estimated incidence rates, based on a complete and validated register containing verified and individually sequenced hip fractures from 1996-2003, for a population of 500,000 people in Funen County, Denmark.
The verified number of the first hip fractures was 6,676, with 520 subsequent fractures. Between 1996 and 2003, the incidence rate of first hip fracture fell by 2.4% per year for males (p = 0.02) and by 1.8% per year for females (p = 0.004). The highest decrease of 3.4% per year (p = 0.02) was seen in 80-84-year-old women.
The incidence rate of the first hip fracture has fallen in both sexes. In most age groups, the actual number of fractures has also decreased. The findings emphasize the need for valid projection studies which should include both demographic projections and modeling of the effects of different levels of prevention.
髋部骨折发病率很高，且随年龄增长而增加。以往研究预测粗发病率和年龄标准化发病率都将持续上升。
我们基于一份完整且经过验证的登记册估算发病率，该登记册包含1996年至2003年丹麦菲英岛县50万人中经过核实且按个体排序的髋部骨折情况。
首次髋部骨折经核实的数量为6676例，后续骨折有520例。1996年至2003年期间，男性首次髋部骨折发病率每年下降2.4%（p = 0.02），女性每年下降1.8%（p = 0.004）。80至84岁女性的年降幅最高，为3.4%（p = 0.02）。
男女首次髋部骨折发病率均有所下降。在大多数年龄组中，骨折实际数量也有所减少。这些发现强调了进行有效预测研究的必要性，此类研究应包括人口统计学预测以及不同预防水平效果的建模。
