Delivery mode affected the saliva cortisol concentration and weight gain recovery four months post-partum. (A) Differences in the saliva cortisol concentration (µg/dL) according to the delivery mode. (B) Evolution of the adjusted maternal weight by breastfeeding during this time, pre-gestational weight, and weight gain over pregnancy from delivery to 4 months post-partum. Data were expressed as mean and 95% CI. (C) Differences in the increment of the maternal weight from pre-gestational weight to 4 months post-partum. (D) Percentage of mothers that had a recovery of their pre-gestational weight 4 months post-partum. Mother was considered to have recovered her pre-gestational weight if they showed a difference between the pre- and post-partum weight below the mean difference + 1SD (standard deviation). * p < 0.05. ** p < 0.01. *** p < 0.001.
