目的 分析中老年女性骨密度的相关因素。方法 从 2 0 0 1年 9月至 2 0 0 2年 8月分层随机抽样 10 90名妇女 ,询问病史、体检 ,按 1∶3的比例随机抽样 330名妇女 ,用双能X线骨密度仪测量其骨密度。结果 随着年龄的增大和绝经年限的延长 ,妇女的骨密度逐渐下降 ,其骨密度值与年龄、绝经年限、初潮年龄、月经周期天数、孕、产次、产后哺乳月数、吸烟、喝酒呈显著负相关 (P <0 . 0 5 ) ,与身高、体重、体重指数呈显著正相关 (P <0. 0 5 )。用逐步回归的方法进行分析 ,年龄、绝经后年限、喝骨头汤量可以进入方程。结论 妇女的骨密度在 4 0岁以上逐渐降低 ,年龄越大、绝经年限越长、孕产次越多、产后哺乳时间越长、有吸烟喝酒习惯者 ,其骨密度较低 ;而体重、体重指数越大 ,其骨密度较高。
Objective To analyze the related factors of bone mineral density in middle-aged and elderly women. Methods From September 2001 to August 2002, 10 90 women were randomly stratified and stratified for medical history and physical examination. A total of 330 women at a ratio of 1: 3 were randomly divided into two groups: Measurement of bone mineral density. Results With the increase of age and menopause, women’s bone mineral density gradually decreased. The BMD of women with age, menopause, menarche, days of menstruation, pregnancy, parity, number of postpartum lactation, smoking and drinking (P <0.05), and had significant positive correlation with height, weight and body mass index (P <0.05). With stepwise regression analysis, age, menopause, drinking bone soup can enter the equation. Conclusions The BMD of women gradually decreased over the age of 40 years. The older the age, the longer the menopause, the more maternity births, the longer the postpartum lactation period, the lower the BMD was. The body weight, body weight The larger the index, the higher the bone density.
