Modern contraceptive discontinuation and associated factors among adolescent girls and young women in Tanzania: An analysis of a nationally representative data.

Background: Contraceptive use is vital in reducing the risk of unintended pregnancies and early motherhood. Despite the well-established benefits, the uptake of modern contraceptive methods among adolescent girls and young women (AGYW) is sub-optimal in sub-Saharan Africa. Furthermore, the discontinuation rate of modern contraceptive use poses a significant challenge to its effectiveness.

A joint survival model for estimating the association between viral load outcome and survival time to death among HIV/AIDS patients attending health care and treatment centers in Tanzania.

Background: Globally, HIV/AIDS is one of the diseases that have a huge burden in terms of cost and health of individuals; and Sub-Sahara Africa is the highly affected region by the pandemic. Tanzania is among the countries that have a higher prevalence of HIV/AIDS-related mortality. This study aimed at using the joint survival model to estimate the association between viral load outcome and survival outcome to death adjusting for age, sex, adherence, and visit date.
