Adolescent contraceptive use DATA FROM THE TANZANIA DEMOGRAPHIC AND HEALTH SURVEY (TDHS), 2010 U N ITE D R E PU B LI C O F TA N Z A N I A What can be done to support Tanzanian adolescents to prevent unintended pregnancy? Plan for how, when and where different groups of sexually active adolescents (married and unmarried, boys and girls, rural and urban) use and do not use contraception. Learn the reasons why adolescents are not using contraception, and develop policies and programmes to better address their needs. Understand that adolescents may get contraception from a variety of sources and ensure that each of these sources can provide high quality services for adolescents. COMPILED IN 2016 | UPDATED NOVEMBER 2016 Adolescent population: who are they? In the United Republic of Tanzania, there are nearly 12 million adolescents aged 10–19 years – 22.8% of the country’s total population.i The majority of adolescents live in rural areas, 67.0% of adolescent girls and 70.7% of adolescent boys.i By age 19, the mean number of years of schooling attended by both adolescent girls and boys is 7.0.ii Among adolescents who become parents before age 20, the average age at which Tanzanian adolescent girls have their first baby is 17.3 years, while the average age at which adolescent boys first become fathers is 17.5.ii Sexual activity and marital status Analysis of data from the TDHSii shows that over 1.6 million Tanzanians aged 15–19 are currently sexually active – they are either unmarried and have had sex in the last three months or they are in a union (i.e. married or living together). On average, among adolescents who had sex before age 20, adolescent girls first have sexual intercourse at age 16.2 years and adolescent boys at 16.8 years. Among unmarried adolescents, 33.1% of adolescent girls report ever having sex and 18.9% are currently sexually active; among adolescent boys, 34.5% report ever having sex, while 19.3% are currently sexually active. Among all Tanzanian adolescents, 18.4% of adolescent girls and 4.2% of adolescent boys are in a union. Among these adolescents, the mean age of the first union is 16.6 years for adolescent girls and 17.9 for adolescent boys. Contraceptive use and non-use among adolescent girls FIGURE 1.

Only 0.3% are using withdrawal, a traditional method (see Figure 1). In union According to TDHSii analyses, 39.8% of adolescent girls in a union report not wanting a child in the next two years, yet only 23.1% of them are currently using any method to prevent pregnancy.
