The main endpoints were gestational weight gain (GWG), GWG as % of the maternal weight at the beginning of pregnancy (GWG%), maternal anemia, SGA and large for gestational age infants (LGA), neonatal intensive care unit admission (NICU). GWG% was 23.8%\u2009\u00b1\u200914.1 in the LGA group vs 13.9%\u2009\u00b1\u200911.0 in the normal weight neonates group; p\u2009&lt;\u20090.03. Patients diagnosed with anemia before pregnancy had higher GWG% than patients without pre-pregnancy anemia (20.1%\u2009\u00b1\u200911.1 vs 13.4%\u2009\u00b1\u200911.6); p\u2009&lt;\u20090.05. GWG% was higher in patients, whose infants were admitted to NICU (25.3%\u2009\u00b1\u200917.6 vs 14.1%\u2009\u00b1\u200911.0; p\u2009&lt;\u20090.04). GWG% can be considered a risk predictor of the LGA and NICU admissions in bariatric patients.
