社会经济地位--收入和文化适应--对髋部骨折的影响还不是很清楚。我们研究了加利福尼亚州8,144,469人中的116,919例骨折。更高的收入和流利的英语预示着较低的骨折发生率。低收入和移民人口患髋部骨折的风险增加，需要干预。种族/民族是髋部骨折风险的主要决定因素。虽然社会经济地位(例如，收入和文化适应)通常与种族/民族有关，但它对髋部骨折发病率的影响还没有得到很好的了解。方法我们对1996年至2000年加州的髋部骨折患者进行了一项基于人群的回顾性研究，并与按邮政编码进行的人口普查估计进行了比较。我们进行了泊松回归分析，计算了性别、年龄、种族/民族、收入、语言(非英语国家者百分比)和居住在农村地区的髋部骨折发生率比。结果在5年期间，8,144,469人中有116,919人发生骨折(2.87个骨折/1,000人/年)。收入越高，髋部骨折的发生率越低。与收入最低的人相比，收入估计值最高的人的发病率比(IRR)为0.79(95%可信区间为0.77至0.82)。居住在非英语人口比例较高的地区的人髋部骨折的内部收益率较高(内部收益率1.004，95%可信区间1.003至1.005)。结论低收入和语言流利性是髋部骨折发病率较高的预测因素。尽管人们对“婴儿潮一代”的老龄化给予了极大关注，但低收入和移民人口患髋部骨折的风险增加，需要干预。
IntroductionThe impact of socioeconomic status—income and acculturation—on hip fracture is not well understood. We studied 116,919 fractures among 8,144,469 people in California. Greater income and English fluency predict lower fracture incidence. Lower income and immigrant populations are at increased risk for hip fracture and require intervention. Race/ethnicity is a major determinant of hip fracture risk. Although socioeconomic status (e.g., income and acculturation) is often associated with race/ethnicity, its impact on hip fracture incidence is less well understood.MethodsWe carried out a retrospective, population-based, study of persons with hip fractures in California, 1996 to 2000, compared to census estimates by zip code. We performed Poisson regression analyses to calculate hip fracture incident rate ratios for gender, age, race/ethnicity, income, language (percent non-English speakers)—a proxy for acculturation—and living in rural areas.ResultsDuring the 5-year period, 116,919 fractures occurred among 8,144,469 persons (2.87 fractures/1,000 persons per year). Higher income predicted lower hip fracture incidence. Persons in the highest decile of estimated income had an incident rate ratio (IRR) of 0.79 (95% confidence interval (CI) 0.77 to 0.82) compared with those in the lowest decile. Greater IRR of hip fracture was predicted for persons living in areas with a greater percent of non-English speakers (IRR 1.004, 95% CI 1.003 to 1.005).ConclusionsLow income and language fluency are predictors of greater hip fracture incidence. Although much attention is given to the aging of the “baby boomers”, low income and immigrant populations are at increased risk for hip fracture and require intervention.
