This article offers an overview of sexual behavior and contraceptive knowledge and use among adolescent women across a large number of developing countries. The results demonstrate that almost universally in sub-Saharan Africa and in the majority of countries in other regions, the gap between age at first sexual intercourse and age at first marriage has increased across age cohorts. The predominant pattern is one in which both age at marriage and age at first intercourse have risen, but the increase in age at marriage is greater, resulting in a widening gap. In most countries in sub-Saharan Africa, current contraceptive use is higher among sexually active, unmarried teens than it is among married teens, whereas in Latin America and the Caribbean, current-use levels are higher among married teens. The results also show that adolescents are unlikely to use a contraceptive the first time they have sex and are more likely than older women to experience a contraceptive failure.
本文概述了众多发展中国家青春期女性的性行为、避孕知识及避孕措施使用情况。结果表明，几乎在整个撒哈拉以南非洲地区以及其他地区的大多数国家，各年龄组首次性行为年龄与初婚年龄之间的差距都有所扩大。主要模式是初婚年龄和首次性行为年龄均有所上升，但初婚年龄的增幅更大，导致差距不断扩大。在撒哈拉以南非洲的大多数国家，性活跃的未婚青少年目前的避孕措施使用率高于已婚青少年，而在拉丁美洲和加勒比地区，已婚青少年的当前使用率更高。结果还表明，青少年在首次性行为时不太可能使用避孕措施，且比年长女性更有可能经历避孕失败。
