Background and objectives: Teenage pregnancy itself is a risk factor for preterm birth in general. However, risk factors for preterm birth comparing teenage mothers who have preterm and no preterm birth are unaware. This study aimed to evaluate risk factors for preterm birth and outcomes of pregnancy among teenage mothers. Materials and methods: A retrospective cohort study of all singleton teenage pregnancy cases giving birth from January 2014 to December 2015 at Khon Kaen Hospital, a tertiary hospital in Thailand, was conducted. Data on the characteristics of teenage mothers and outcomes of pregnancy were extracted from electronic files of medical records. Teenage mothers were classified into two groups according to gestational age at the time of delivery: term and preterm, to identify risk factors of preterm birth among teenage mothers. Multivariable logistic regression analysis was used to evaluate independent risk factors for preterm births among teenage mothers. Results: During the study period, 1042 teenage mothers were identified. The preterm birth rate among teenage mothers was 16.8%. BMI before pregnancy <18.5 kg/m2 (OR, 1.89; 95% CI, 1.28–2.81), weight gain <5 kg (OR, 5.11; 95% CI, 2.96–8.81), prenatal care visit <4 times (OR, 5.16; 95% CI, 3.50–7.61), premature rupture of membranes (OR, 4.22; 95% CI, 2.20–8.11), and previous preterm birth (OR, 46.56; 95% CI, 13.15–164.88) were found to be independent risk factors for preterm births among teenage mothers. Conclusion: Previous preterm birth showed a very strong effect on current preterm birth. All risk factors for preterm birth should be considered to prevent preterm births among teenage mothers. Emphasizing the importance of prenatal care visits and proper nutrition for teenage pregnancy women would be beneficial.
