We studied factors associated with oral contraceptive (OC) use among 1,855 premenopausal women who were admitted to hospital with conditions unrelated to OC use. Among this group, 15 per cent reported having used OCs within the preceding year and 35 per cent reported having last used them more than a year previously. A higher estrogenic dose (more than 60 micrograms) was reported by past users; the relationship of numerous other variables to past and present OC use is reported.
我们对1855名因与口服避孕药使用无关的疾病入院的绝经前女性中与口服避孕药(OC)使用相关的因素进行了研究。在这组人群中,15%报告在前一年使用过OC,35%报告最后一次使用OC是在一年多以前。过去的使用者报告使用过雌激素剂量更高(超过60微克)的药物;还报告了许多其他变量与过去和现在OC使用之间的关系。
