主　　题：combined oral contraceptives (COC) ethinylestradiol/desogestrel ethinylestradiol/ cyproterone acetate bone mineral density (BMD) 

摘      要：Objective To compare bone mineral density （BMD） among users of ethinylestradiol/ desogestrel, ethinylestradiol/cyproterone acetate and nonhormonal control subjects. Methods The study included 154 women aged 25-40 years. Forty-six women were using ethinylestradiol/desogestrel （group A） and 55 women using ethinylestradiol/cyproterone acetate （group B）for 24 months and 53 women using nonhormonal contraception as control subjects （group C）. BMD of the lumbar spine and femoral neck were obtained using dual energy X-ray absorptiometry, comparing mean BMD changes in combined oral contraceptives （COCs） users with nonusers. Results For 24 months of treatment, lumbar spine and femoral neck BMD values in women who used ethinylestradiol/desogestrel and ethinylestradiol/cyproterone acetate were not significantly different compared with the baseline and the values of subjects in nonuser （P〉0.05）. Conclusion There was no statistical difference in BMD between the users of ethinylestradiol/desogestrel or ethinylestradiol/cyproterone acetate and nonusers.
