We studied neonatal outcomes of infants of obese mothers in a cohort of 6,125 deliveries, using logistic multivariate analysis to remove the role of potential confounding variables. Although, as in previous reports, the crude unadjusted prevalence of several adverse neonatal outcomes was higher in these infants, the multivariable analysis revealed that only two outcomes remained significantly associated with maternal overweight and obesity: neonatal macrosomia (adjusted odds ratios aOR 1.4, p<0.001) and meconium aspiration syndrome (aOR 1.6, p0.05), indicating that the unadjusted association with the other outcomes was caused by confounding factors. Nonetheless, as macrosomia is associated with increased health risks both to the mothers and their infants, and maternal obesity with considerable maternal morbidity during pregnancy, these results should not lead to complacency, but instead encourage better prevention of obesity in general and during pregnancy in particular.
