<mods:abstract>[EN]BACKGROUND: Adolescent reproductive health is part of internationally agreed development goals. Unmarried&#xd;
adolescents are not commonly included in global monitoring of contraceptive use&#xd;
despite the more severe consequences of unintended childbearing for them.&#xd;
OBJECTIVE: We document levels and trends of contraceptive prevalence and demand for married and&#xd;
sexually active unmarried adolescent women aged 15–19 in Latin America and sub-&#xd;
Saharan Africa. We estimate the effect of adolescent contraceptive use and marital status&#xd;
on fertility and the impact of meeting current demand.&#xd;
METHODS: We propose a fertility model informed by the proximate determinants framework separating&#xd;
adolescents by marital status. Linear Mixed Model estimates are based on aggregate&#xd;
data from 120 DHS surveys for 34 developing countries.&#xd;
RESULTS: Increasing contraceptive prevalence has already reduced adolescent fertility by 6.8% in&#xd;
Latin America and 4.1% in sub-Saharan Africa. Meeting the total demand for contraceptives&#xd;
of unmarried adolescents would lead to an additional decrease in fertility of 8.9%&#xd;
and 17.4% respectively.&#xd;
CONCLUSIONS: Contraceptive demand and prevalence are generally higher for sexually active unmarried&#xd;
adolescent women than for those married. Increasing prevalence has already had an impact&#xd;
in declining fertility, but there is a potentially larger effect if high levels of unmet&#xd;
need are eliminated, particularly in sub-Saharan Africa. Such reduction would have a&#xd;
significant impact on adolescent health. CONTRIBUTION : We provide evidence of the importance of contraceptive use of unmarried sexually active&#xd;
adolescent women in explaining trends in adolescent fertility. We estimate the potential&#xd;
effect of meeting the contraceptive needs of married and unmarried adolescents on&#xd;
unintended childbearing.</mods:abstract>
