大量避孕药具停用导致数百万妇女的避孕需求得不到满足。然而，其对意外生育的影响尚不清楚。36个国家的人口与健康调查中的生育日历数据被用来估计因避孕药具停用而导致的近期意外生育的百分比。在所有国家中，避孕药具中断约占最近意外分娩的三分之一。方法失败和因其他原因停止避孕占了这一贡献的大部分。使用现代避孕方法会增加避孕中断对意外生育的影响，但在一定避孕普及率水平上，随着避孕方法的组成向有效性更高、持续时间更长的方法转变，避孕中断对意外生育的影响会减少。在过去，大量避孕药具停用而生育意愿没有改变，导致了数百万的意外生育。随着预计更多地使用现代方法，这一贡献可能会增加。使目前的使用者能够减少方法失败的情况，并鼓励他们在停止使用原来的方法后改用另一种方法，将是减少避孕药具停用及其对意外生育的影响的有效战略。
High contraceptive discontinuation results in millions of women having an unmet need for contraception. However, its contribution to unintended fertility is not known. Reproductive calendar data in Demographic and Health Surveys in 36 countries are used to estimate the percent of unintended recent births attributable to contraceptive discontinuation. Contraceptive discontinuation accounted for about one-third of unintended recent births in all countries together. Method failure and contraception discontinued for other reasons accounted for most of this contribution. The contribution of contraceptive discontinuation to unintended births increases with the use of modern methods but decreases as method composition at a given level of contraceptive prevalence shifts toward methods with higher effectiveness and longer continuation. High contraceptive discontinuation in the past without changes in fertility intentions has resulted in millions of unintended births. This contribution is likely to increase with the anticipated increase in the use of modern methods. Enabling current users to reduce method failure and encouraging them to switch to another method after discontinuing the use of the original method will be an effective strategy to reduce contraceptive discontinuation and its contribution to unintended births.
