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

Table 5 Associations between prenatal cadmium exposure and relative cord blood TL, stratified by infant sex and maternal age

Subgroup	n	Percentage change(%)^* (95% CI)	P for interaction
Infant sex			0.907
Male	206	− 5.52 (− 12.24, 1.71)
Female	204	− 8.26 (− 14.45, − 1.63)
Maternal age at delivery (years)			0.797
< 29	201	− 8.47 (−15.45, − 0.91)
≥ 29	209	− 5.29 (−11.28, 1.11)

Models’ adjustments are according to model C in Table 3. *Estimates are percentage changes in relative cord blood TL of per doubling in urinary cadmium concentration
