13629例女性初潮年龄、生育次数、绝经年限与骨密度相关性研究

13629 cases of female menarche age,the number of births,years since menopause and bone mineral density correlated research

目的研究女性月经初潮年龄、生育次数、绝经年限与前臂远端骨密度的相关关系。方法周围型双能X线骨密度仪(pDEXA)检测前臂远端骨密度,用自制的问卷调查表记录受试者月经初潮年龄、生育次数及绝经年龄、绝经年限,测量身高、体重。结果月经初潮年龄与骨密度明显负相关,生育次数与骨密度负相关,绝经年限与骨密度负相关。结论月经初潮年龄决定峰值骨量,生育次数和绝经是骨质疏松的危险因素。

Objective Study of female menarche age, number of births, years since menopause and the correlativity with distal forearm bone mineral density （BMD）. Methods Peripheral dual-energy X-ray absorptiometry （pDEXA） test distal forearm BMD, self-made questionnaire with the records of the subjects menarche age, number of births, and menopause age, years since menopause, measured height, weight. Results Menopause age are significantly negatively related to BMD. The number of births is negatively correlated with BMD. Years since menopause is negatively correlated with BMD. Conclusion The age of menarche decided to peak bone mass. The number of births and menopause are risk factors for osteoporosis.
