A scoping review on sexual and reproductive health behaviors among Tanzanian adolescents

BACKGROUND: There is wide variation among societies in profiles of adolescent health and behaviors, but they all experience sexual and reproductive health as a major challenge. However, adolescents in middle- and low-income countries are of particular concern, as it is the case in Tanzania, where limited social, educational, and health services contribute to make them victims of unwanted pregnancies, unsafe abortion, and sexually transmitted infections including HIV. Thus, we undertook a descriptive systematic scoping review of the available published information on sexual and reproductive health among Tanzanian adolescents. METHODS: We performed a scoping review to collect and analyze observational data on sexual and reproductive health behaviors among Tanzanian adolescents. Publications were identified using PubMed®, Scopus®, Web of Science™, and Cochrane Library electronic databases from 2000 to December 2017. A protocol was defined to identify relevant studies. We included original observational studies conducted in Tanzania and published in English, both quantitative and qualitative, involving adolescents (10 to 19 years old), and that considered at least one of the following items: condom use, number of sexual partners, sexual debut, contraceptive prevalence, sexually transmitted infections, unwanted pregnancies, abortion, or knowledge about reproductive health. All included articles were coded according to relevant exposures or outcomes and subsequently analyzed to assess frequencies. RESULTS: After screening for inclusion criteria, 13 publications were included in the datasheet developed to record the findings. Overall, the publications revealed that adolescents tend to be sexually active, with high rates of early sexual debut, have multiple sexual partners, and a limited use of condom and contraceptives. Sexual coercion and transactional sex were also frequent. Only one study addressed pregnancy as an outcome, and a single study looked at the relevant health services. No study was retrieved describing the frequency of unsafe abortion. CONCLUSION: Adolescents engage in high-risk sexual behaviors and experience its adverse consequences. It is essential to collect more information, but the existing evidence supports a need for improving provision of sexual and reproductive health services among Tanzanian adolescents.
