Background: The incidence of obesity has increased to pandemic proportions over the last 20 years. Maternal obesity is associated with a wide array of adverse maternal pregnancy outcomes and increased risks in the offspring. The aim of the study was to find the effect of obesity on maternal and perinatal outcome in obese women in comparison to those of normal weight women.Methods: The study was designed as a case-control study. Antenatal women with first trimester body mass index (BMI) of more than 30 kg/m2 constituted the cases and those with BMI between 18 and 24.9 kg/m2 formed the controls.Results: There was increased incidence of antepartum complications in obese women. Obese women had a significant history of prior treatment for infertility (p<0.00001). The incidence of gestational diabetes (OR 4.76, 95%CI 1.267-17.72 p=0.014), gestational hypertension (OR 3.05, 95%CI 1.01-9.20 p=0.04), induction of labor (OR 2.5, 95%CI 1.0-6.28 p=0.04), preeclampsia (OR 2.38, 95%CI 1.0-5.64 p=0.04, Caesarean section (OR 1.98, 95%CI 1.24-3.14 p=0.003), postpartum haemorrhage (OR 8.57, 95%CI 1.07-76.15 p=0.04) and wound infection (OR 8.57, 95%CI 1.07-76.15 p=0.04) and adverse neonatal outcomes such as higher mean birth weight (p<0.0001) and requirement of NICU (OR 2.79, 95%CI 1.33 -5.84 p=0.006) was higher in obese women.Conclusions: Obesity is an independent risk factor for adverse pregnancy outcomes and hence, interventions directed towards weight loss and prevention of excessive weight gain must begin in the preconception period.

ObjectiveTo examine the association between high maternal weight status and complications during pregnancy and delivery.SettingScotland.ParticipantsData from 132 899 first-time singleton deliveries in Scotland between 2008 and 2015 were used. Women with overweight and obesity were compared with women with normal weight. Associations between maternal body mass index and complications during pregnancy and delivery were evaluated.Outcome measuresGestational diabetes, gestational hypertension, pre-eclampsia, placenta praevia, placental abruption, induction of labour, elective and emergency caesarean sections, pre-term delivery, post-term delivery, low Apgar score, small for gestational age and large for gestational age.ResultsIn the multivariable models controlling for potential confounders, we found that, compared with women with normal weight, the odds of the following outcomes were significantly increased for women with overweight and obesity (overweight adjusted ORs; 95% CI, followed by the same for women with obesity): gestational hypertension (1.61; 1.49 to 1.74), (2.48; 2.30 to 2.68); gestational diabetes (2.14; 1.86 to 2.46), (8.25; 7.33 to 9.30); pre-eclampsia (1.46; 1.32 to 1.63) (2.07; 1.87 to 2.29); labour induction (1.28; 1.23 to 1.33), (1.69; 1.62 to 1.76) and emergency caesarean section (1.82; 1.74 to 1.91), (3.14; 3.00 to 3.29).ConclusionsWomen with overweight and obesity in Scotland are at greater odds of adverse pregnancy and delivery outcomes. The odds of these conditions increases with increasing body mass index. Health professionals should be empowered and trained to deliver promising dietary and lifestyle interventions to women at risk of overweight and obesity prior to conception, and control excessive weight gain in pregnancy.

Background: Overweight, obesity, and morbid obesity in the mother are associated with adverse obstetrics well as neonatal outcome. Aim of this study was to assess the prevalence of overweight and obesity, and the impact of body mass index (BMI) on maternal and neonatal outcome.Methods: This is a retrospective study from January 2018 to September 2018 on 180 women with singleton term pregnancies. Maternal and neonatal outcomes at delivery were noted.Results: In present study, 3 (1.66%) pregnant women were underweight, 57 (31.66%) pregnant women had normal BMI, 71 (39.44%) pregnant women were overweight while 49 (27.22%) pregnant women were obese. Gestational weight gain was less than 8 kgs in 40 (22.22%) pregnant women, weight gain was 8-15.9 kgs in 132 (73.33%) pregnant women while weight gain was more than 16 kgs in 8 (4.44%) pregnant women. Out of 3 underweight women, 1 delivered by cesarean section and 2 had normal delivery, out of 57 women with normal BMI, 21 delivered by cesarean section and 36 had normal delivery, out of 71 overweight women, 47 delivered by cesarean section and 34 had normal delivery while out of 49 obese women, 38 delivered by cesarean section and 11 had normal delivery. PET and GDM was seen in 9 (7.5%) women each while macrosomia were seen in 5 (4.16%) women.Conclusions: Increased association was seen with maternal obesity and adverse outcome of pregnancy like PIH, GDM, cesarean section.

AbstractThe relevance of pregestational body mass index (BMI) on adverse pregnancy outcomes remained unclear in Southwest China. This study aimed to investigate the overall and age-category specific association between pre-gestational BMI and gestational diabetes mellitus (GDM), preeclampsia, cesarean delivery, preterm delivery, stillbirth, macrosomia, and small-for-gestational age (SGA) or large-for-gestational age (LGA) neonates in Southwest China. Furthermore, it explores the relative importance of influence of pregravid BMI and maternal age on pregnancy outcomes. 51,125 Chinese singleton pregnant women were recruited as study subjects. Multiple logistic regression models were used to examine the influence of pre-pregnancy BMI on adverse pregnancy outcomes. Gradient boosting machine was used to evaluate the relative importance of influence of pregravid BMI and maternal age on pregnancy outcomes. It is found that women who were overweight or obese before pregnancy are at higher risk of adverse pregnancy outcomes except for SGA neonates, while pre-pregnancy underweight is a protective factor for GDM, preeclampsia, cesarean delivery, macrosomia and LGA, but not SGA. Younger mothers are more susceptible to GDM and macrosomia neonates, while older mothers are more prone to preeclampsia. Pre-pregnancy BMI has more influence on various pregnancy outcomes than maternal age. To improve pregnancy outcomes, normal BMI weight as well as relatively young maternal ages are recommended for women in child-bearing age.

Objective To examine the change in body mass index (BMI) categories between pregnancies and its effect on adverse pregnancy outcomes. Study Design We performed a retrospective cohort study of women with two consecutive deliveries from 2005 to 2010. Analysis was limited to women with BMI recorded at <24 weeks for both pregnancies. Standard BMI categories were used. Adverse pregnancy outcomes included preterm birth at <37 weeks, intrauterine growth restriction (IUGR), pregnancy-related hypertension, and gestational diabetes mellitus (GDM). Women with increased BMI category between pregnancies were compared with those who remained in the same BMI category. Results In total, 537 women were included, of whom 125 (23%) increased BMI category. There was no association between increase in BMI category and risk of preterm birth, IUGR, or pregnancy-related hypertension. Women who increased BMI category had an increased odds of GDM compared with women who remained in the same BMI category (6.4 vs. 2.2%; p = 0.018). The increased risk remained after controlling for age, history of GDM, and starting BMI (adjusted odds ratio: 8.2; 95% confidence interval: 2.1–32.7; p = 0.003). Conclusion Almost one-quarter of women increased BMI categories between pregnancies. This modifiable risk factor has a significant impact on the risk of GDM.
