    Abstract:
    This paper presents a study of adolescent pregnancy in which different age groups were compared to establish which age group had the greatest incidence of risk factors. Primiparous adolescents who delivered at the Obstetric Clinic of the Medical School of the University of Sao Paulo, Brazil, between January 1975 and June 1980 were studied. During this period, 13,961 births occurred, of which 105 were to 9-15 year olds (0.7%), 137 were to 16 year olds (0.9%) and 106 were to 17 year olds (0.7%). A large majority of the adolescents in each age group were unmarried; similarly, a lack of adequate prenatal care was observed in all 3 groups. A gestational age of less than 38 weeks was encountered in 30.5% (30 cases), and 16.9% (18 cases), respectively, in the 9-15, 16, and 17 year age groups. Among pregnancy complications, there was an elevated incidence of arterial hypertension in all 3 groups, as well as an increased occurrence of eclampsia among the 9-15 year olds. Urinary infections and anemia were also evident during pregnancy. Analgesia was required in 22 cases (20.9%) of the 9-15 year old age group, in 3 cases (2.2%) of the 16 year age group, and in 2 cases (1.9%) of the 17 year age group. Fetal presentation, duration of labor, type of birth (normal, forceps, or cesarean), puerperal morbidity, birth weight, and perinatal mortality for each of the 3 groups are presented in tables. Neonatal deaths were determined to be the consequence of prematurity and its complications except in 1 case of congenital heart disease which occurred in the 17 year old group. Neonatal jaundice was the most frequent cause of morbidity in the newborns. The results of this study agree with those of similar studies appearing in the literature. The authors attribute the greater frequency of premature births among 9-16 year olds to immaturtity of uterine muscle fiber, deficient prenatal care, and the emotional tensions to which the adolescents were subjected, as well as to medical complications of pregnancy and general maternal physical immaturity. The 17 year olds presented behavior closer to that of the adult population.
