60～74岁女性骨质疏松症相关因素分析

目的：探讨老年女性低骨密度值的相关因素，为老年女性骨质疏松的早期防治提供理论依据。方法：用双能X线吸收法(DEXA)测定915例第一汽车制造厂60~74岁退休女性职工尺桡骨的骨密度值，并对年龄，大米、杂粮、海产品、牛奶、酸奶、咖啡、豆浆、面、鸡蛋、水果的摄入量，是否吸烟，是否饮酒及绝经年数等进行问卷调查,同时测量身高、体质量。结果：年龄、是否经常摄入面、鸡蛋和水果、是否吸烟、绝经年数、体质指数（BMI）与骨密度值有关，差异有显著性(P<0.05)；多重逐步回归分析显示：年龄与骨密度值呈负相关(B=－0.440，P<0.05)，绝经年数与骨密度值呈负相关(B=－0.314，P<0.05)，是否吸烟与骨密度值呈负相关(B=－0.650，P<0.05)，BMI与骨密度值呈正相关(B=0.959，P<0.05)。结论：高龄、吸烟、绝经年数长、低BMI是60~74岁女性原发性骨质疏松的相关危险因素 。

Analysis on relative factors of osteoporosis in old women aged 60-74 years

Objective To explore the relative factors of low bone mineral density in old women in order to provide a theoretical basis for early prevention and treatment for osteoporosis in old women. Methods Using dual-energy X-ray absorptiometry (DEXA),the ulna and radius bone mineral densities of 915 old women who were 60-74 year-old women retired workers of China First Automobile Works were determined. Questionnaire was divided into age,the intakes of rice,coarse food grain,marine products,milk,acidophilous milk,coffee,bean milk,flour,eggs,fruit,whether smoking or not,whether drinking or not and years of menopause,the body height and the body weight were measured at the same time. Results Age,whether take in flour,eggs and fruit frequently,whether smoking or not,postmenopausal years and body mass index(BMI) were correlated with bone mineral density(P<0.05);multiple gradual regressive analysis demonstrated that the age was negatively correlated with bone mineral density(B=-0.440,P<0.05),the postmenopausal year was negatively correlated with bone mineral density(B=-0.314,P<0.05),smoking was negatively correlated with bone mineral density(B=-0.650,P<0.05). BMI was positively correlated with bone mineral density(B=0.959,P<0.05).Conclusion Old age,long post-menopausal years,low BMI,and smoking are relative factors of primary osteoporosis in old women aged 60-74 years.
