**Correlation is significant at the ≤0.01 level (2 tailed). *Correlation is significant at the ≤0.05 level (2 tailed). Note: BMI is body mass index, NEQ total is the Night Eating Questionnaire total score, EPDS is the Edinburgh Postnatal Depression Scale. The restraint scale item is from the Eating Inventory. Sleep variables are subscales of the Pittsburgh Sleep Quality Index. Parity is the number of previous live births. Smoking status indicated whether they smoked or not during pregnancy. Higher scores on the NEQ, EPDS, and the subscales of the Pittsburgh Sleep Quality Index indicate more pathology. Higher scores on the restraint scale item indicate a higher cognitive restraint over eating.
