Two hundred and nine inadvertent pregnancies in oral contraceptive users were studied to determine the associated factors. The percentage of Pill types also were compared with the market usage over the same period. We found that the classically-suggested cofactors, such as missed pills, late pills, drug ingestion, and gastrointestinal upsets were reported commonly. The triphasic Pills also were represented more frequently than would have been expected from their share of the market.
对209例口服避孕药使用者的意外妊娠情况进行了研究,以确定相关因素。还将避孕药类型的占比与同期的市场使用情况进行了比较。我们发现,经典的相关因素,如漏服、服药延迟、药物摄入和胃肠道不适等情况较为常见。三相片在意外妊娠中的占比也高于其在市场份额中的预期。
