Mediation model of maternal glucose and BMI with childhood adiposity with newborn adiposity as the mediator. Diagram of a mediation analysis displaying maternal predictors glucose sum of z-scores and BMI (measured at mean 27.7 weeks gestation), childhood sum of skinfolds outcome (measured at mean 11.4 years of age), and newborn sum of skinfolds (measured at delivery) as the mediator. Regression coefficients and 95% CIs are reported for total effects of maternal glucose and BMI on childhood sum of skinfolds (c1 and c2) and indirect effects of maternal glucose and BMI on the newborn sum of skinfolds mediator (a1 and a2). The proportion of the total effect of maternal glucose sum of z-scores on childhood sum of skinfolds mediated by newborn sum of skinfolds is 15.0%. The proportion of the total effect of maternal BMI on childhood sum of skinfolds mediated by newborn sum of skinfolds is 2.9%.
