老年股骨颈骨折的危险因素

Risk factors for femoral neck fracture in elderly population

目的:探索影响老年群体发生股骨颈骨折的危险因素。方法:选取因外伤住院的老年(年龄≥60岁)患者124例,其中股骨颈骨折71例(57%),非股骨颈骨折53例(43%)。收集并统计所有患者的年龄、性别、体重指数(body mass index,BMI)、骨密度(bone mineral density,BMD)、大腿长径、大腿平均腿围,先后以单因素分析、多因素logistic回归分析研究股骨颈骨折的危险因素。结果:单因素分析结果显示:两组患者的年龄、性别、BMI、BMD、大腿长径、大腿平均腿围差异均有统计学意义(均P<0.05)。多因素logistic回归分析结果显示:年龄、性别、BMI、BMD、大腿长径、大腿平均腿围是老年人股骨颈骨折的影响因素(均P<0.05)。结论:高龄、女性、低BMI(体重过低)、低BMD(骨质疏松症)、大腿长径长、大腿平均腿围小为老年人发生股骨颈骨折的危险因素。

Objective:To explore the risk factors for femoral neck fracture in elderly population.Methods:A total of 124 elderly patients(≥60 years old)in hospital for trauma were enrolled,including 71 patients(57%)with femoral neck fracture and 53 non-femoral neck fracture patients(43%).All patients’age,gender,body mass index(BMI),bone mineral density(BMD),thigh length and average circumference were collected.Single factor analysis and multivariate logistic regression analysis were performed to explore whether the above factors were risk factors for femoral neck fracture.Results:Single factor analysis showed that the age,gender,BMI,BMD,thigh length,and average thigh circumference between the 2 groups were statistically different(all P<0.05),and multi-factor logistic regression analysis showed that age,gender,BMI,BMD,thigh length,and average thigh circumference were influencing factors for femoral neck fracture in elderly population(all P<0.05).Conclusion:Older age,female,lower BMI index(low body weight),lower BMD(osteoporosis),longer thigh length,and lower average circumference are risk factors for femoral neck fracture in the elderly population.
