Résumé : This article presents an analysis of Demographic and Health Survey (DHS) data from developing countries that sheds light on the reproductive behavior of adolescent women. Topics include sex behavior and marriage; contraceptive knowledge/usage; contraceptive usage at first intercourse; and contraceptive failure, switching, and discontinuation. Tables illustrate 1) the percentage of all adolescents aged 15-19 who have ever had sex and who have ever married in 37 DHS countries; 2) the percentage of those aged 20-24 and of women aged 40-44 who first married and first had sex by age 18 in 36 DHS countries; 3) the percentage of women aged 15-19 and 20-49 who know any contraceptive method by marital and sexual activity status in 37 DHS countries; 4) the percentage of women aged 15-19 and 20-49 currently using contraception by marital status and sexual activity status in 43 DHS countries; 5) the percentage of people who used contraception at first intercourse by country, age, sex, and marital status in 6 countries; and 6) 12-month life-table gross discontinuation rates by country and age at start of use, by type of discontinuation. It is concluded that adolescent sex behavior and contraceptive knowledge/usage vary widely across and within regions, but that overall patterns show that the gap between first intercourse and marriage has increased. Levels of contraceptive knowledge are high, and usage is higher but less successful among unmarried than married adolescents. More research should be directed toward adolescent males.
