title: Pregnancy after Bariatric Surgery: Obstetric and Perinatal Outcomes and the Growth and Development of Children.
abstract: BACKGROUND
  Several outcomes of pregnancy after bariatric surgery are currently being studied.
  
  
  METHODS
  This cross-sectional, retrospective study evaluated the obstetric and perinatal outcomes of pregnancies in 19 women who underwent bariatric surgery, as well as the growth and development of their children, in the Southern Brazil.
  
  
  RESULTS
  Among these women, 11 children were born prior to surgery and 32 were born post-surgery. The mean time between the surgery and the first pregnancy was 42.96 months. Preterm newborns were more common among the pre-surgery childbirths. Regarding growth, normal weights were observed in 27.3 % of the children in the pre-surgery births and obesity was observed in 54.5 %. In contrast, normal weights were observed in 59.4 % of the children born during the postoperative period and obesity was observed in 31.2 %. The average excess weight that the women lost prior to pregnancy was 64.88. Speech delays were found in three male children evaluated using the Denver Developmental Screening Test II. A statistical association was found between the interval from the surgery to the pregnancy and the outcome of the questionable Denver II test results (p = 0.011).
  
  
  CONCLUSIONS
  Except for the large index of low birth weight, it can be concluded that pregnancy after bariatric surgery is safe. The growth rate was found to be adequate in the children born after the surgery, with reduced obesity. Although changes in speech development were detected, no factors were supported an association with pregnancy after bariatric surgery.
