^a Adjusted for maternal education, socioeconomic status, ethnicity and offspring sex

^b Further adjusted for proxies for indication for cesarean section (c-section), including toxemia, diabetes in pregnancy, multiple pregnancy, birth order, maternal age at delivery, smoking during pregnancy, preterm and post-term delivery, low and high birth weight and previous c-section

^c Interaction was examined by adding cross-product terms between upper quartile of maternal pre-pregnancy BMI (vs. rest) and mode of delivery to the multivariable model

^d Subgroup of singleton first births within the cohort, without toxemia or diabetes in pregnancy. The restricted sample included 9,160 offspring born vaginally and 631 born by c-section, of which 1,089 and 102 were overweight/obese, respectively.
