摘要
目的探讨绝经后妇女的绝经年限及年龄与骨量丢失率关系。方法1999年5月-2003年4月,对已绝经的1467例妇女进行骨密度测定,并对不同绝经后妇女年龄、绝经年限与骨密度关系进行分析。结果1467例绝经后妇女中,以绝经1-5年期间和40-45岁时各部位骨密度作为基线值比较,绝经已超过35年或年龄大于80岁时各部位骨密度最低。其中按绝经年限腰椎、股骨颈、大转子、华氏三角区在绝经后6-10年间和超过35年时丢失速度最快;按年龄腰椎在56-65岁、股骨颈和华氏三角区在61-65岁、大转子在71-75岁及各部位大于80岁时丢失速度最快。结论绝经后妇女绝经年限及年龄增加,腰椎、股骨颈、粗隆、华氏三角区骨量丢失增加。绝经年限及年龄不同,各部位丢失速度不同。
Objective To evaluate the relationship between menopause years, age and bone mineral density （BMD） loss rate in postmenopausal women. Methods From May 1999 to April 2003, BMD of 1467 postmenopausal women was measured by Norland XR-36 dual energy X-ray absorptiometry （DXA）. Relationship between years and age of menopause and BMD was analyzed. Results Compared with BMD of women 1 - 5 years postmenopausal and aged 40 - 45 years, BMD was lowest in group of those over 35 years postmenopausal and over 80 years old. Bone loss rate was fastest in 6 - 10 years or over 35 years postmenopausal in regions like lumbar, femoral neck, Troch Wards. Bone loss rate was fastest in lumbar during 56 - 65 years, in Neck. Wards during 61 - 65 years, and in Troch during 71 - 75 years and all regions over 80 years. Conclusions BMD decreased as the durations and age of menopause increased. The bone loss rate varies among different groups of menopause years and age.
