ABSTRACT
Maternal gestational obesity is related to risk of obesity in the child. This risk may be in part mediated by altered child temperament, which can affect mother-child interactions, including feeding and soothing behaviors that affect obesity risk. Our objective was to examine the association between maternal pre-pregnancy BMI and child zBMI and determine if child temperament, specifically positive Affectivity/Surgency, mediates this association. Using conditional process modeling, we analyzed data from 408 mother-child dyads enrolled in the Alberta Pregnancy Outcomes and Nutrition (APrON) study. Child temperament was assessed at 3 years of age via a parent report measure, the Child Behavior Questionnaire (CBQ), and child zBMI was calculated from in-person measurements of child height and weight at 4-5 years of age. Bivariate correlations showed that there was a significant positive correlation between zBMI and Surgency (r = 0.11, p = 0.03), and zBMI was also correlated with maternal pre-pregnancy BMI (r = 0.12, p = 0.02). Multivariable regression revealed that maternal pre-pregnancy BMI (adjusted ß = 0.15, 95% confidence interval [CI]; 0.00-0.05, p = 0.02) and Surgency scores (adjusted ß = 0.14, 95% CI; 0.02-0.28, p = 0.03) were associated with higher child zBMI at 4-5 years of age. Mediation analysis showed that Surgency mediated the association between pre-pregnancy BMI and child zBMI. Our models controlled for maternal gestational weight gain, gestational diabetes, socioeconomic status, maternal anxiety and depression, and gestational age at birth. Overall, maternal pre-pregnancy BMI was positively associated with child zBMI, and this association was mediated by higher child Surgency scores.
