Haemoglobin, ferritin and transferrin as target variables. Net household income, highest education, occupational status, pubertal stage and gender as predictors. Significant correlations are bold.

*B indicates the regression coefficient.

†95% CI for B.

‡Bilateral significance P<0.05.

§Pubertal stage gives no information beyond the information of the other variables; therefore, it was removed from the analyses.
