Fertility surveys have rarely asked people who are using contraception about the contraceptive method they would like to be using, implicitly assuming that those who are contracepting are using the method they want. In this commentary, we review evidence from a small but growing body of work that oftentimes indicates this assumption is untrue. Discordant contraceptive preferences and use are relatively common, and unsatisfied preferences are associated with higher rates of method discontinuation and subsequent pregnancy. We argue that there is opportunity to center autonomy and illuminate the need for and quality of services by building on this research and investing in the development of survey items that assess which method people would like to use, as well as their reasons for nonpreferred use. The widespread adoption of questions regarding method preferences could bring indicators of reproductive health services into closer alignment with the needs of the people they serve.

会议对特定避孕方法的偏好：一个过期的指标

生育率调查很少询问正在采取避孕措施的人他们想要使用的避孕方法，隐含地假设那些正在避孕的人正在使用他们想要的方法。在这篇评论中，我们审查了来自一小部分但不断增加的工作的证据，这些证据通常表明这种假设是不正确的。不一致的避孕偏好和使用相对普遍，不满意的偏好与较高的方法中断率和随后的怀孕率相关。我们认为，通过以这项研究为基础并投资于开发评估人们喜欢使用哪种方法以及他们不喜欢使用的原因的调查项目，有机会集中自治并阐明服务的需求和质量。
