Repeated measures linear mixed model analyses were adjusted for clustering of data within persons, child ethnicity (Western/non-Western) and residential socioeconomic status score. ES = Effect size (Cohen’s d). * Significant difference (1 year: B = − 0.11, 95% CI -0.21; 0.00, p = .04, 2 years: B = − 0.25, 95% CI -0.38; − 0.12, p < .001). † Numbers shown are unstandardized beta-coefficient and 95% confidence interval of linear mixed model (B (95% CI))
