目的探讨绝经后骨质疏松症患者L2-4骨密度值降低的危险因素的相关性及其程度。方法对已确诊为绝经后骨质疏松症的92例患者进行危险因素的回顾性问卷调查,以L2-4骨密度值为因变量,各危险因素为自变量,建立多元逐步回归模型,进行相关性分析。结果绝经后妇女年龄越大、绝经越早、绝经年限越长、体重指数越小,骨密度越低。结论绝经年限、牛奶摄人史、绝经年龄、初潮年龄、骨折史及弯背对绝经后妇女的L2-4骨密度值有较大的影响,尤其是绝经年限的影响作用最大。普及骨质疏松症危险因素的防治常识,具有重要意义。 Objective To investigate the correlation between the risk factors of L2-4 BMD in postmenopausal osteoporosis patients and its extent. Methods 92 cases of postmenopausal osteoporosis who were diagnosed as postmenopausal women were retrospectively investigated for risk factors. The L2-4 BMD was used as the dependent variable and the risk factors were independent variables. The multiple stepwise regression model was established and correlated Sexual analysis. Results The higher the age of postmenopausal women, the earlier the menopause, the longer the menopause, the smaller the body mass index, the lower the BMD. Conclusion Menopause, history of milk intake, age of menopause, age of menarche, history of fracture and flexion have a significant effect on L2-4 BMD of postmenopausal women, especially menopausal years. It is of great significance to popularize common sense of prevention and treatment of risk factors of osteoporosis.
