Objectives: To verify the prevalence of pregnancy among adolescents under 16 years of age, the risk of pregnancy-induced hypertension and neonatal complications in the population attend at the Hospital Geral do Grajaú. Methods: Data related to every delivery performed at the Hospital Geral do Grajaú (HGG) from January 1st, 2000 to April 30th, 2004 were collected. The sample was divided into two groups of pregnant women: one consisting of adolescents aged under 16 years, and the other comprising all other pregnant women attended at the Institution. Maternal age, prevalence of pregnancy-induced hypertension, number of prenatal visits, mode of delivery, gestational age, birth weight and one-minute Apgar score were analyzed. For statistical analysis the t test was used considering p<0.05. Data regarding pregnant teenagers were compared to those related to the general patient population of the Obstetrics Clinic of the HGG. These data were obtained from the HGG's Hospital Records Department. Results: Two hundred and thirty-one pregnant teenagers under 16 years of age were analyzed. This corresponds to 2.61% of the total obstetric population studied in this Institution. Among them, 53,2% did not attend prenatal care visits adequately, that is, they attended less than 5 visits. The prevalence of pregnancy- induced hypertension among these teenagers was 3.46%. Cesarean section was performed in 22% of the teenagers studied. There were 12.1% of low-birth weight newborns and 23.8% preterm infants, of whom 6.4% had a one-minute Apgar score = 3, and 17.7% had an Apgar score = 7. A statistically significant difference was observed regarding inadequate prenatal care, one-minute Apgar score = 3 and prematurity, compared to the data from the total pregnant population of the Institution. Conclusions: A higher risk of pregnancy- induced hypertension among pregnant adolescents aged under 16 years compared to the general population of patients of the Institution was not observed. However, the age range studied proved to be a risk factor for neonatal morbidity.
