奥斯陆髋部骨折的发病率在过去几十年中呈长期增长趋势。本研究的主要目的是报告目前奥斯陆髋部骨折的发病率，并确定骨折的发生是否存在季节性变化。使用电子诊断登记簿和奥斯陆具有躯体护理的医院的手术室列表，识别了1996年5月1日至1997年4月30日期间ICD-9代码820.X（髋部骨折）的所有患者。获得了所有确定的患者的医疗记录，并验证了诊断。使用1997年1月1日奥斯陆的人口作为风险人口，计算年龄和性别特异性的年发病率。这些比率与1988/89年和1978/79年的比率作了比较。获得了奥斯陆的室外温度数据，以研究温度与髋部骨折数量之间的关系。共纳入1316例髋部骨折，其中78%发生在女性中。在两种性别中均观察到发病率随年龄呈指数增加。1996/1997年，50岁以上年龄组妇女和男子按年龄调整的骨折率分别为每10 000人118.0和44.0例，1988/1989年为124.3和44.9例，1978/1979年为104.5和35.8例。在1996/97年，髋部骨折的发病率没有明显的季节性变化，平均室外温度与每个月骨折数量之间也没有相关性。数据显示，近十年来，奥斯陆髋部骨折的发病率没有明显变化，目前仍是报告的最高发病率。奥斯陆寒冷的气候似乎并没有导致高发病率。(C)2001年，Elsevier Science Inc.

The incidence of hip fractures in Oslo has shown a secular increase during the past decades. The main aims of the present study were to report the current incidence of hip fractures in Oslo and to determine whether there is a seasonal variation in the occurrence of fractures. Using the electronic diagnosis registers and the lists of the operating theater for the hospitals in Oslo with somatic care, all patients with ICD-9 code 820.X (hip fracture) from May 1, 1996 to April 30, 1997 were identified. Medical records for all identified patients were obtained and diagnosis was verified. Using the population of Oslo on January 1, 1997 as the population at risk, the age- and gender-specific annual incidence rates were calculated. These rates were compared with those for 1988/89 and 1978/79. Outdoor temperature data for Oslo were obtained to study the relation between temperature and number of hip fractures. A total number of 1316 hip fractures was included, of which 78% occurred in women. An exponential increase in incidence with age was observed in both genders. The age-adjusted fracture rates per 10,000 for the age group greater than or equal to 50 years were 118.0 and 44.0 in 1996/97, 124.3 and 44.9 in 1988/89, and 104.5 and 35.8 in 1978/79 for women and men, respectively. There was no significant seasonal variation in the incidence of hip fractures and no correlation between mean outdoor temperature and number of fractures for each month in 1996/97. The data show that the incidence of hip fractures in Oslo has not changed significantly during the last decade, and it is still the highest reported. The cold climate of Oslo does not seem to contribute to the high incidence. (C) 2001 by Elsevier Science Inc. All rights reserved.
