Introduction: default malnutrition is critical in the gestational period since it results adversely for maternal, fetal and newborn health. Objective: to determine the perinatal outcome in pregnant women with low weight prior pregnancy in Santa Cruz del Norte for 2 years. Methods: we performed a prospective observational analytical study from July 2009 to June 201. Our universe was 152 pregnant women with low weight when recruiting, a sample of 112 pregnant women were chosen to formed the study group and a control group of normal-weight 219 patients was formed randomly from the medical practices following multiple criteria. The data were collected by the review of clinical and obstetric records and they were processed using descriptive and inferential statistics. Results: significantly, patients with low pre-pregnancy weight were observed to have preterm labor (20.5 %), premature rupture of membranes (17.9 %), insufficient weight gain (43.8 %), growth restriction (14.3 %), congenital malformations (2.7 %), preterm delivery (6.3 %), and low birth weight (8.9 %). Respiratory distress was a significant complication in newborns (10.7 %), and endometritis and urinary sepsis in the postpartum women (16.1 % and 5.4 % respectively). Conclusions: nutritional disorders at the beginning of pregnancy bring an increase in maternal and perinatal morbidity, since the risk of obstetrical, fetal, postnatal and newborn conditions increased.
