This is one of the reviews of literature and projects of sexual and reproductive health of adolescents and youths in eight Asian countries. Adolescents and youth make up one fourth of the population in the Western Pacific Region. At least 17% out of 37 countries and areas in the region have a median age below 25 years. The health of adolescents is, therefore, a key element and an investment for social and economic progress. As a result of these reviews, countries now have evidence-based information for the development of national policies and strategies for adolescent sexual and reproductive health.
