目的 :探讨长效避孕针醋酸甲孕酮 (DMPA)对中国妇女骨质代谢的影响。方法 :自愿使用 15 0mgDMPA避孕者 30人组成实验组 ,采用阴茎套避孕者 30人组成对照组。测定两组血清雌二醇 (E2 )、血清碱性磷酸酶 (AKP)、尿钙 /肌酐 (Ca/Cr)、尿羟脯氨酸 /肌酐 (Hyp/Cr)及非惯用臂桡尺骨超远端骨矿含量 (BMC)、骨矿密度 (BMD)。结果 :两组血清雌二醇、血清碱性磷酸酶、尿钙 /肌酐、尿羟脯氨酸 /肌酐差异无显著性 (P >0 .0 5 ) ,两组非惯用臂桡尺骨超远端骨矿含量、骨矿密度差异无显著性 (P >0 .0 5 )。结论 :使用DMPA避孕 1年对妇女骨质代谢无影响。
Objective: To investigate the effect of long-acting contraceptive needle medroxyprogesterone acetate (DMPA) on the bone metabolism in Chinese women. Methods: A group of 30 volunteers who used 150 mg of DMPA contraceptive voluntarily to form an experimental group and 30 condom-pregnant women as a control group. Serum estradiol (E2), serum alkaline phosphatase (AKP), urinary calcium / creatinine (Ca / Cr), hydroxyproline / creatinine (Hyp / Cr) Bone mineral content (BMC), bone mineral density (BMD). Results: The serum estradiol, serum alkaline phosphatase, urinary calcium / creatinine, urinary hydroxyproline / creatinine showed no significant difference between the two groups (P> 0.05) Bone mineral content, bone mineral density difference was not significant (P> 0.05). CONCLUSION: One year of DMPA contraception had no effect on women’s bone metabolism.
