¹Model 1 is unadjusted. Model 2 is adjusted for mother´s age, gestational week at birth, and birth weight. The model for plasma 25(OH)D₃ is additionally adjusted for season of sampling. rTL, relative telomere length; 25(OH)D₃, 25-hydroxycholecalciferol.

²During pregnancy (mean gestational week 27).
