aim: to compare perinatal results of pregnant adolescents that attend the prenatal control consultation at hcg with those published by the clap for adolescent population in latin america. materials and methods: 360 medical records of pregnant patients under 18 years, that undertook prenatal control at the adolescents’ clinic of the department of obstetrics of the hcg in 2010, were studied. the variables included in the study were those related with prenatal care, childbirth and postpartum. hypothesis testing was used to compare the results obtained in this investigation with those reported by the clap. 1.96 was adopted as the critical value from z distribution (p <0.05). results: this study showed that maternal morbidity and mortality of adolescent patients that received attention in our hospital is lower than that reported by the clap. although there was a higher percentage of some diseases such as urinary tract infections or anemia in our population, this might be due to a better case detection system rather than to an increase in disease. with regard to the newborn, there were no significant differences with respect to the percentage of preterm births, low birth weight or very low birth weight. the fact that approximately 97% of patients had their labor at term or close to it (more than 34 weeks gestation) and having a neonatal intensive care unit could explain the low neonatal mortality present in our study’s adolescents. conclusions: maternal and neonatal morbidity and mortality in adolescent patients that received attention in our hospital is lower than that reported by clap for adolescent populations.
