Table 3 Percentage change in relative TL by prenatal cadmium exposure (N = 410)

From: Prenatal cadmium exposure is associated with shorter leukocyte telomere length in Chinese newborns

  Percentage change(%)* (95% CI) P value
Unadjusted − 5.30 (− 9.63, − 0.77) 0.022
Model A − 5.34 (− 9.66, − 0.81) 0.022
Model B − 5.73 (− 10.18, − 1.06) 0.017
Model C − 6.83 (− 11.44, − 1.97) 0.006
  1. *Estimates are percentage changes in relative cord blood TL of per doubling of urinary cadmium concentration
  2. Model A, adjustment for newborn characteristics (infant sex and gestational age)
  3. Model B, additionally adjustment for maternal characteristics (maternal age at delivery, educational level, passive smoking in pregnancy, prepregnancy BMI, parity, hypertensive disorders in pregnancy, and gestational diabetes mellitus)
  4. Model C, additionally adjustment for zinc (Ln-transformed, μg/g creatinine) and selenium (Ln-transformed, μg/g creatinine)
