Prevalence and associated factors of sexually transmitted infections among adolescent pregnant women at Mbarara Regional Referral Hospital, Uganda

Nearly one in eight pregnant adolescents at MRRH were infected with HIV, syphilis or HBV, with these STIs more likely to be among multigravidae and former users of non-barrier contraception and less likely among married/cohabiting pregnant adolescents. These findings support integrating repeat HIV-syphilis testing, dual-method contraceptive counselling and targeted interventions for multigravidae into youth-friendly antenatal services to advance STI-elimination goals.
