STUDY OBJECTIVE: To examine the extent to which socioeconomic status (SES), mental health, and substance use are associated with teenage pregnancies in Southwestern Ontario (SWO), and whether these pregnancies are at an elevated risk for adverse birth outcomes, after controlling for medical, behavioral, and SES factors.
DESIGN: Retrospective cohort study using perinatal and neonatal databases.
SETTING: Tertiary care hospital in SWO.
PARTICIPANTS: Women residing in SWO who gave birth to singleton infants without congenital anomalies between 2009 and 2014. Teenage pregnancies (≤ 19 years) were compared to women 20-34 years and 35+.
MAIN OUTCOME MEASURES: Low birth weight (LBW), very LBW, term LBW, preterm birth (PTB), very PTB, low and very low Apgar score, and fetal macrosomia.
RESULTS: Out of 25,263 pregnant women, 4.3% were ≤19 years. About 18% of teenage mothers lived in socioeconomically disadvantaged neighborhoods, compared to 11% of mothers aged 20-34 and 9% of women ≥35 years (p<0.001). Teenage mothers had higher rates of depression during pregnancy (9.8%) than mothers 20-34 years (5.8%) and ≥35 years (6.8%) (p<0.001). Young mothers self-reported higher tobacco, marijuana, and alcohol use during pregnancy than adult mothers (p<0.001). Teenage pregnancy increased the risk of a low Apgar score (aOR: 1.56; 95% CI: 1.21, 2.02), but was not associated with other birth outcomes after adjusting for covariates.
CONCLUSION: Teenage pregnancy is associated with a higher risk of socioeconomic disadvantage, mental health problems and substance use during pregnancy, but is largely unrelated to adverse birth outcomes in SWO.
