Table 2. Risk of overweight, obesity and overnutrition provided the child was born by Caesarean section. The Young Lives Study, Younger Cohort, Peru.

Crude model, only include the outcome and exposure; Model A adjusted by child sex, child age at baseline, breastfeeding, hospitalised after birth, birth weight and child birth order; Model B adjusted only by location at baseline, maternal BMI at baseline, wealth index at baseline, and maternal education; Model C adjusted by all the previous variables. In bold, p < 0.05. C-sect: Caesarean section.
