[WEIGHT GAIN DURING PREGNANCY AND PERINATAL OUTCOMES IN PREGNANT ADOLESCENTS WITH A HISTORY OF SEXUAL ABUSE].

OBJECTIVE
the purpose of the present study was to describe some perinatal outcomes in two groups of pregnant adolescents: one group with history of sexual abuse and one group without sexual abuse antecedent.


METHODS
we designed an observational, retrolective study. Participants were primigravid adolescents between 10 to 16 years, with a singleton pregnancy, and at least three prenatal medical evaluations. Participants were grouped according to sexual abuse antecedent: 55 adolescents had sexual abuse antecedent, and 110 participants had not sexual abuse antecedent. We obtained the clinical data from medical records: socio-demographic characteristics, sexually transmitted infections, illicit drugs use, pre-gestational body mass index, gestational weight gain, and newborn weight. The data were analyzed using association tests and mean comparisons.


RESULTS
the adolescents with sexual abuse history had higher prevalence of human papilloma virus infection. The newborns weight of mothers without sexual abuse antecedent was about 200 grams higher than the newborns of mothers with sexual abuse antecedent (p = 0.002); while the length of the first group was 2 centimeters longer than the length of the newborns on the second group (p = 0.001). Gestational weight increase was 5 kilograms lower in adolescents with sexual abuse antecedent compared to adolescent without the antecedent (p = 0.005). Illicit drug use was similar in the two groups and it was associated to low newborn weight.


CONCLUSIONS
the sexual abuse antecedent in pregnant adolescents was associated to higher frequency of human papilloma virus infections, lower newborn weight, and lower gestational weight increase on pregnant adolescents.
