Plain English Summary Adolescent pregnancies are a global problem occurring in high-, middle-, and low-income countries with Uganda having one of the highest adolescent pregnancy rates in sub-Saharan Africa. We compared the risk of adverse birth outcomes, including major external birth defects, between adolescents, (age 12–19 years) and mothers (age 20–34 years) in four urban hospitals. All informative births, including live births, stillbirths, and spontaneous abortions; regardless of gestational age, delivered at four selected hospitals in Kampala from August 2015 to December 2018 were examined. Demographic data were obtained by midwives through maternal interviews and review of hospital patient notes. Of the 100,189 births, 11.0% were among adolescent mothers and 89.0% among mothers (20–34 years). Adolescent mothers were more likely than mothers (20–34 years) to have an infant with preterm delivery, low birth weight, early neonatal death, and major external birth defects. Adolescent pregnancies were also associated with an increased risk of gastroschisis when compared to mothers (20–34 years). In conclusion, this study found that adolescent mothers had an increased risk for several adverse birth outcomes compared to mothers 20–34 years. Research on the potential underlying causes or mechanisms for these adverse outcomes among adolescent births is necessary to identify possible interventions.
