Adverse Perinatal Outcomes Among Teenage Mothers Delivering at a Tertiary Referral Hospital in Southwestern Uganda: Prevalence and Associated Factors

Introduction: Each year, millions of teenagers in low-resource areas experience unintended pregnancies, many of which result in childbirth. These pregnancies often carry an increased risk of negative perinatal outcomes. Objectives: The study determined the prevalence and factors associated with adverse perinatal outcomes among teenagers delivering at a tertiary referral hospital in southwestern Uganda. Methods: This cross-sectional study was carried out in the Department of Obstetrics and Gynecology. We consecutively included all teenagers (13-19 years) in the postnatal ward who delivered. Descriptive statistics were used to summarize demographic and outcome data, and multivariable logistic regression analysis was used to identify factors associated with adverse perinatal outcomes. Results: Overall, 327 participants were enrolled. The mean age was 18.4 (SD 1.1) years, while the mean number of antenatal care (ANC) visits attended was 4.6 (SD 1.9). Less than half delivered by cesarean 136 (41.6%) and 16 (4.9%) were HIV seropositive. Approximately 140 (42.8%) participants had adverse perinatal outcomes, including neonatal death (7, 2.1%), APGAR score at five minutes <7 (44, 13.5%), or low birth weight <2.5 kg (52, 15.9%). ANC attendance was mildly protective against adverse perinatal outcomes (aOR 0.91 (95% CI 1.14, 3.01), p=0.03). Feeling indifferent toward the pregnancy was associated with increased odds of one or more adverse perinatal outcomes compared to feeling happy about the pregnancy (aOR 3.39 (95% CI 1.11, 10.37), p=0.02). Participants with a history of prior miscarriage had increased odds of adverse perinatal outcomes (aOR 9.03 (95% CI 2.45, 25.53), p=0.04). Conclusions: Nearly half of teenagers experienced adverse perinatal outcomes, and a history of prior miscarriage was a significant risk factor for adverse perinatal outcomes, while ANC was protective. Prospective cohort studies to explore the newborn and child developmental outcomes among children born to teenage mothers are also recommended.
