Abstract

Context: Maternal age, parity, and socioeconomic class are important determinants of obstetric outcome of pregnancy. Teenage pregnancy constitutes a high risk pregnancy with complications arising from a combination of physiological, anatomical, and socioeconomic factors.
Objective: The objective was to determine the current incidence of all teenage pregnancies and their obstetric outcomes at UNTH, Enugu.
Materials and Methods: This was a retrospective review of all teenage pregnancies at University of Nigeria Teaching Hospital, Enugu over a 6-year period (2000--2005). A total of 74 teenage pregnancies were analyzed and compared with 105 controls (adult mothers).
Results: Records of 74 teenage pregnancies were identified within the study period which constitutes 1.67% of 4422 deliveries within the period. Majority of the teenagers (78.3%) were nulliparous. There was statistically significant differences between the teenage mothers and older mothers in the rate of unemployment (75.7% vs. 24.8%, P = 0.000), booking status (41.9% vs. 100%, P = 0.000) anemia (32.4% vs. 24.8%, P = 0.001), unsure of last menstrual period (32.4% vs. 15.2%, P = 0.007), caesarean section (18.9% vs. 10.5%, P = 0.000), cephalopelvic disproportion as an indication for caesarean section (9.4% vs. 3.8%, P = 0.001), preterm delivery (18.9% vs. 11.4%, P = 0.001), low birth weight (23.0% vs. 10.5%, P = 0.005), episiotomy (61.7% vs. 28.7%, P = 0.001), instrumental delivery (6.8% vs. 2.9% P = 0.001), Apgar score at 1 minute (35.1% vs. 19.1% P = 0.005), and perinatal mortality (16.2% vs. 12.4%). There were no maternal deaths.
Conclusion: Pregnant teenagers are at higher risk than their older counterparts. Female socioeducational development and proper use of contraceptive services will help reduce teenage pregnancy rate, while perinatal care will help to minimize it associated hazards.
