Abstract

Abstract Objectives: The aim of the study was to retrospectively evaluate the effectiveness of a fertility awareness-based method supported by a mobile-based application to prevent unwanted pregnancies as a method of natural birth control. Methods: In a retrospective analysis, the application’s efficiency as a contraceptive method was examined on data from 4054 women who used the application as contraception for a total of 2085 woman-years. Results: The number of identified unplanned pregnancies was 143 during 2053 woman-years, giving a Pearl Index of 7.0 for typical use. Ten of the pregnancies were due to the application falsely attributing a safe day within the fertile window, producing a perfect-use Pearl Index of 0.5. Calculating the cumulative pregnancy probability by life-table analysis resulted in a pregnancy rate of 7.5% per year (95% confidence interval 5.9%, 9.1% per year). Conclusions: The application appears to improve the effectiveness of fertility awareness-based methods and can be used to prevent pregnancies if couples consistently protect themselves on fertile days.

基于生育意识的避孕手机应用程序

摘要目的:本研究的目的是回顾性评估基于生育意识的方法的有效性，该方法由基于移动的应用程序支持，以防止意外怀孕作为自然节育的一种方法。方法:通过回顾性分析，对4054名使用该应用程序作为避孕方法的妇女的数据进行了检查，共计2085女性年。结果:2053例妇女年中发现143例意外妊娠，典型使用珍珠指数为7.0。其中10例怀孕是由于应用程序错误地将生育窗口内的安全日归因于此，从而产生了0.5的完美使用珍珠指数。通过生命表分析计算累积妊娠概率，妊娠率为每年7.5%(95%置信区间为5.9%，9.1% /年)。结论:该应用程序似乎提高了基于生育意识的方法的有效性，如果夫妇在生育期始终如一地保护自己，则可用于预防怀孕。
