Available contraceptives are not meeting many women's needs, as is evident by high levels of typical-use failure, method switching and discontinuation. To improve women's satisfaction with contraceptive methods, determining what features they prefer and how these preferences are satisfied by available methods and methods under development is crucial.
The importance of 18 contraceptive method features was rated by 574 women seeking abortions--a group at high risk of having unprotected intercourse and unintended pregnancies--at six clinics across the United States in 2010. For each available and potential method, the number of features present was assessed, and the percentage of these that were "extremely important" to women was calculated.
The three contraceptive features deemed extremely important by the largest proportions of women were effectiveness (84%), lack of side effects (78%) and affordability (76%). For 91% of women, no method had all of the features they thought were extremely important. The ring and the sponge had the highest percentage of features that women deemed extremely important (67% each). Some streamlined modes of access and new contraceptive technologies have the potential to satisfy women's preferences. For example, an over-the-counter pill would have 71% of extremely important features, and an over-the-counter pericoital pill, 68%; currently available prescription pills have 60%.
The contraceptive features women want are largely absent from currently available methods. Developing and promoting methods that are more aligned with women's preferences presumably could help increase satisfaction and thereby encourage consistent and effective use.
现有的避孕方法并不能满足许多女性的需求,这从典型使用失败率、方法转换和停止使用率都很高就可以看出。为了提高女性对避孕方法的满意度,确定她们喜欢哪些特性,以及这些特性如何被现有的和正在开发的方法所满足,这一点至关重要。
2010 年,在美国六个诊所中,有 574 名寻求堕胎的女性(一群有很高无保护性行为和意外怀孕风险的人)对 18 种避孕方法的特征的重要性进行了评分。对于每一种现有的和潜在的方法,评估了存在的特征数量,并计算了这些特征中对女性“极其重要”的百分比。
有三个避孕特征被大多数女性认为是极其重要的,分别是有效性(84%)、无副作用(78%)和负担得起(76%)。对于 91%的女性来说,没有一种方法拥有她们认为极其重要的所有特征。环和海绵拥有女性认为极其重要的特征比例最高(各占 67%)。一些简化的获取方式和新的避孕技术有可能满足女性的偏好。例如,一种非处方避孕药将拥有 71%的极其重要的特征,一种事后非处方避孕药将拥有 68%;目前可获得的处方避孕药拥有 60%。
女性想要的避孕方法的特征在现有的方法中大多不存在。开发和推广与女性偏好更一致的方法,大概可以帮助提高满意度,从而鼓励她们持续、有效地使用。
