Contraceptive preferences are important for reproductive outcomes, such as contraceptive continuation and pregnancy. Current approaches to measuring reproductive preferences in population surveys are limited to exploring only fertility preferences and implicitly assume that contracepting people are using a method they want. We know that people change their fertility preferences over the life course as a response to life events, but there is no information about changes in contraceptive preferences, given the limited evidence about the measurement and distribution of contraceptive preferences. In this study, we examined the extent of change in women's contraceptive preferences over one year and identified characteristics associated with this change in Kenya using three rounds of nationally representative longitudinal data. Over one year, 18 percent of contraceptive users and 46 percent of contraceptive nonusers reported changes in their preferred contraceptive. Experiencing a pregnancy or birth and changes in marital status were associated with changes in contraceptive preferences for users and nonusers. We found that contraceptive preferences are dynamic, suggesting that family planning programs should ensure people's access to various methods to respond to women's changing circumstances and preferences.

避孕方法偏好稳定吗？衡量肯尼亚女性首选方法的变化


避孕偏好对于生殖结果很重要，例如继续避孕和怀孕。目前在人口调查中测量生殖偏好的方法仅限于探索生育偏好，并隐含地假设避孕者正在使用他们想要的方法。我们知道，人们在生命历程中会改变生育偏好，作为对生活事件的反应，但由于有关避孕偏好测量和分布的证据有限，没有关于避孕偏好变化的信息。在这项研究中，我们研究了一年内妇女避孕偏好的变化程度，并使用三轮具有全国代表性的纵向数据确定了肯尼亚与这一变化相关的特征。一年多来，18% 的避孕药使用者和 46% 的非避孕药使用者表示他们首选的避孕药具发生了变化。怀孕或分娩以及婚姻状况的变化与使用者和非使用者避孕偏好的变化有关。我们发现避孕偏好是动态的，这表明计划生育方案应确保人们能够采用各种方法来应对妇女不断变化的情况和偏好。
