Correlation involving an ordinal variable uses Spearman’s correlation coefficient; all others use Pearson’s. SEX: Male = 1, SEX: Female = 2; URB/RUR: rural = 1, URB/RUR: urban = 2. * p < 0.05, ** p < 0.01, *** p < 0.001. DAZ—development-for-age z score, HAZ—height for age z score, WAZ—weight for age z score, MAT_ED—maternal education, SES—socioeconomic status, FCI—family care indicators.
