title: Maternal weight gain in women with gestational diabetes mellitus.
abstract: OBJECTIVE
  The aim of the study was to examine the perinatal outcomes in gestational diabetes in women with body mass index (BMI)-adjusted gestational weight gain (GWG) according to the Institute of Medicine (IOM) 2009 recommendations.
  
  
  METHODS
  The clinic's database was used to analyze 675 singleton GDM pregnancy outcomes. GWG for the entire pregnancy was compared to IOM recommendations and adjusted for prepregnancy BMI categories: underweight <18.5; normal 18.5-24.9; overweight 25-29.9; and obese >30. The study group was divided into three categories: below IOM limits, within IOM limits and above IOM limits.
  
  
  RESULTS
  Only 37% of women achieved the proper weight gain (n=256). Almost 30% of women with GDM (n=196) had an excessive weight gain. GWG above limits was associated with a significantly higher neonatal measurements and a higher rate of large-for-gestational-age neonates. In underweight and normal-prepregnancy-weight women, no relation between GWG and birth-weight percentile was noted. For the overweight and obese women, a positive significant correlation between GWG until GDM diagnosis and birth-weight percentile was noted (P=0.002), which was not present when GWG until delivery was considered.
  
  
  CONCLUSIONS
  Limited weight gain in overweight and obese women with gestational diabetes mellitus results in favourable pregnancy outcomes.
