目的:探讨绝经前后女性前臂骨密度随年龄及月经状况变化的趋势。方法:用双能X线骨密度仪测量20～80岁绝经前后的女性702例,按10岁年龄段及绝经前后分组比较骨密度变化的规律。结果:绝经前后的女性前臂各部位在40～49岁年龄段获得峰值骨密度;比较绝经前后的女性,其前臂不同部位的骨密度存在显著性区别。结论:女性前臂骨密度随年龄及月经状况存在动态变化,其测定能反映骨代谢水平的变化
Objective: To investigate the changes of the forearm bone mineral density with age and menstrual status before and after menopause. Methods: 702 women aged 20 ~ 80 years before and after menopause were measured by dual-energy X-ray absorptiometry. The changes of bone mineral density were compared according to 10-year-old group and premenopausal group. Results: Before and after menopause, the female forearm obtained the peak BMD in the 40-49 age group. Compared with the premenopausal women, the BMD in different parts of the forearm was significantly different. Conclusion: There is a dynamic change in the forearm BMD with age and menstrual status, which can reflect the change of bone metabolism
