Prior studies have suggested that hip fracture rates are substantially lower in Asian countries than in the United States. However, comparisons have been limited by unavailability of recent data, differences in case definition, lack of data from similar time periods, and small sample sizes. This study sought to examine trends by age and sex, with separate statistics for those aged 85 or older.
Hospital discharge data were used to obtain hip fracture incidence in Hong Kong and the United States from 1988 through 1989.
Within each population, women had higher hip fracture rates than men. Fracture rates in the United States were significantly higher for both sexes than rates in Hong Kong. For persons over the age of 80, rates of hip fracture among White US males exceeded those for Hong Kong women. Inclusion of transferred cases in hip fracture rates minimized differences between the countries.
Despite increasing hip fracture rates in Hong Kong, those rates are still substantially lower than the rates in the United States. Identifying factors responsible for this variation may prove useful in the search for preventive strategies.
先前的研究表明，亚洲国家的髋部骨折发生率远低于美国。然而，由于缺乏近期数据、病例定义不同、缺乏相似时间段的数据以及样本量较小，这些比较受到了限制。本研究旨在按年龄和性别研究趋势，并对85岁及以上人群进行单独统计。
利用医院出院数据获取1988年至1989年香港和美国的髋部骨折发病率。
在每个人口中，女性的髋部骨折发生率都高于男性。美国男女的骨折发生率均显著高于香港。对于80岁以上的人，美国白人男性的髋部骨折发生率超过了香港女性。将转院病例纳入髋部骨折发生率可最大限度地减少两国之间的差异。
尽管香港的髋部骨折发生率在上升，但仍远低于美国。确定造成这种差异的因素可能有助于寻找预防策略。
