“Nearly 60 percent of non pregnant women between the reproductive ages of 20 and 39 years are overweight, with 34.0 percent being obese. Maternal pre pregnancy obesity is associated with several pregnancy complications including gestational diabetes, hypertension, preeclampsia, preterm delivery, postpartum infection, and cesarean section deliveries.”
The enclosed article is from Birth Journal and whilst it refers to an American Study it contains some information n that is no doubt relevant to the Australian Setting!
The findings of the study which involved over 2000 women found that “Obese women had 1.78 times the odds of cesarean delivery as compared with women with a normal BMI (95% CI: 1.44–2.16). When adjusted for race/ethnicity, live birth order, household income, and education, the association increased in magnitude and remained statistically significant (OR = 2.01, 95% CI: 1.63–2.43). The obesity–cesarean delivery association persisted and remained statistically significant among all maternal weight gain categories.”
