Changes in prepregnancy body mass index between the first and second pregnancies and risk of large-for-gestational-age birth

Obstetrical and Neonatal Outcomes of Pregnancies following Gastric Bypass Surgery: A Retrospective Cohort Study in a French Referral Centre

“…These results are consistent with those of Patel et al [22] and Richards et al [23]. There is a well-established association between macrosomia and maternal obesity [24], and a correlation between maternal BMI and mean birthweight [25]. In contrast, we observed more small for gestational age (SGA) neonates [26] in the RYGBP group than in both control groups (8.3%, 0.8%, and , respectively), although the trend was not statistically significant.…”

Prepregnancy body mass index in a first uncomplicated pregnancy and outcomes of a second pregnancy

“…In a populationbased retrospective cohort analysis, women who were overweight or obese before their first pregnancy had increased adjusted odds for LGA, preeclampsia, and cesarean delivery in their second pregnancy as compared to women who had a normal weight before both pregnancies, even if they had reached a normal weight by their second pregnancy. [7][8][9] While these findings suggest that prepregnancy BMI might have adverse effects on pregnancy outcomes in subsequent pregnancies, it is unclear if the increased risk is driven by recurrence of adverse outcomes in the first pregnancy.…”

Obésité et grossesse: revue des risques et de la prise en charge obstétricale

“…Peu d'études d'intervention ont été publiées jusqu'à ce jour, mais plusieurs sont en cours. Par contre, des études rétrospectives observent que la perte de poids avant une grossesse restaure le cycle menstruel [42] et diminue les risques de prééclampsie, de macrosomie et de césarienne [43,44].…”
