We explore the patterns of adolescents' need for contraception in 46 low- and middle-income countries.
Using data from the Demographic and Health Surveys, we estimate the prevalence of never-use, ever-use and current contraceptive use of sexually active adolescent girls ages 15-19. We use weighted fixed-effects meta-analytic techniques to estimate summary measures. Finally, we highlight country profiles of adolescent contraceptive use.
More than half (54.4%) of sexually active or girls in unions report never using contraception, while 13.3% report having used contraception but not currently doing so. Nearly a third report currently using a contraceptive method: 24.6% are using a modern short-term method, 2.5% are using a most effective method, and 5.2% are using a traditional method.
We find significant heterogeneity across countries as well as within countries based on adolescents needs for spacing, limiting and method preference. With more than half of sexually active adolescents having never used contraception, the potential for unwanted pregnancies is high.
While there is no single strategy to address adolescents' contraceptive needs, country programs may want to consider the heterogeneity of adolescents' risks for unintended pregnancy and tailor programs to align with the profile of adolescents in their settings.
我们探索了 46 个中低收入国家青少年避孕需求的模式。
利用来自人口与健康调查的数据,我们估计了年龄在 15-19 岁之间有过性行为的青少年女孩从未使用、曾经使用和当前使用避孕措施的比例。我们使用加权固定效应荟萃分析技术来估计汇总指标。最后,我们突出了各国青少年避孕使用情况的概况。
超过一半(54.4%)有过性行为或处于婚姻关系中的女孩报告从未使用过避孕措施,而 13.3%的女孩报告曾经使用过避孕措施但目前不再使用。近三分之一的女孩报告目前正在使用避孕方法:24.6%使用现代短期方法,2.5%使用最有效的方法,5.2%使用传统方法。
我们发现各国之间以及各国内部在间隔、限制和方法偏好方面存在显著的异质性。由于超过一半的有过性行为的青少年从未使用过避孕措施,因此意外怀孕的风险很高。
虽然没有一种单一的策略可以满足青少年的避孕需求,但国家项目可能需要考虑到青少年意外怀孕风险的异质性,并根据其所在环境中青少年的特点来调整项目。
