“…Pregnant women who put on excessive weight have an OR of 1.4 for caesarean delivery. 46 Of note, both high and low weight gains are associated with increased risk for preterm birth. 45 It has also been found that there is a positive correlation between gestational weight gain and birth weight, especially among underweight and normal weight women.…”

“…Studies have reported an association between insufficient weight gain in pregnancy and increased risk of low birth weight, intrauterine growth restriction, and prematurity 4,5 . Meanwhile, excessive weight gain has been associated with increased incidence of diabetes mellitus and gestational hypertension, cesarean delivery, fetal macrosomia, perinatal morbidity and mortality, postpartum weight retention, and childhood obesity 6,7,8,9,10 .…”

Inadequate weight gain during pregnancy is an important predictor of complications for the mother and infant. This cross-sectional study assessed factors associated with inadequate weight gain among women in the third trimester of pregnancy who received prenatal care under the Brazilian Unified National Health System (SUS) in the city of Rio de Janeiro, Brazil, from November 2007 to July 2008. A total of 1,079 pregnant women were interviewed, and adequacy of weight gain was obtained by calculating weight gain as recommended by the U.S. Institute of Medicine. Social, demographic, and obstetric factors were analyzed as independent variables. A multinomial logistic regression model was used, and pregnant women with weight gain below or above the recommended levels were compared to those with adequate weight gain. Low schooling was associated with insufficient weight gain, while excessive gain was observed in women with hypertension and pre-gestational underweight, overweight, and obesity. Nutritional assessment during prenatal care is essential, and interventions should target cases of inadequate weight gain in order to prevent complications for the mother and infant.

“…[9][10][11] Incremental increases in gestational weight gain have also been associated with greater risk for caesarean delivery, independently of its effects on fetal growth. [12][13][14] Several explanations have been proposed to account for the increased risk of caesarean delivery among women with high body mass. The association has been attributed to the presence of medical conditions associated with obesity (hypertension and diabetes), 9 a reduced rate of cervical dilatation among obese women, 15 and the possibility that an increased depot of soft tissues in the maternal pelvis may obstruct labour and lead to dystocia or cephalopelvic disproportion.…”

Objective To quantify the effects of pre-pregnancy body mass and gestational weight gain, above and beyond their known effects on birthweight, on the risk of primary and repeat caesarean delivery performed before or after the onset of labour.Design Hospital-based historical cohort study.Setting Canadian university-affiliated hospital.Population A total of 63 390 singleton term ( ‡37 weeks gestation) infants with cephalic presentation.Methods We studied prospectively archived deliveries at the Royal Victoria Hospital in Montreal, Canada, from 1 January 1978 to 31 March 2001 using multiple logistic regression models to estimate relative odds of caesarean delivery.Main outcome measure Caesarean delivery, primary or repeat and before or after the onset of labour.Results Pregravid obesity (body mass index ‡30 kg/m 2 ) increased the likelihood of primary caesarean delivery before (OR = 2.01, 95% CI 1.39-2.90) and after (OR = 2.12, 95% CI 1.86-2.42) the onset of labour. High net rate of gestational weight gain (>0.50 kg/week) increased the risk but only after labour onset (OR = 1.40, 95% CI 1.23-1.60). Among women with a previous caesarean, high weight gain modestly increased risk but only before labour (OR = 1.38, 95% CI 1.04-1.83), whereas obesity increased the risk of caesarean delivery both before (OR = 1.85, 95% CI 1.44-2.37) and after (OR = 1.96, 95% CI 1.11-3.47) labour onset. Increased risks of macrosomia accounted for the association between pregravid adiposity and repeat caesarean delivery performed after but not before the onset of labour.Conclusions Pregravid obesity increases the risk of caesarean delivery both before and after the onset of labour and both with and without a history of caesarean.
