The Association between Hepcidin and Iron Status in Children and Adolescents with Obesity

Table 2

Correlations between BMI-SDS, serum hepcidin-25, and iron profiles in all children.

Variables	Hb (95% CI)	Hct (95% CI)	Serum iron (95% CI)	Ferritin (95% CI)	TIBC (95% CI)	TS (95% CI)
BMI-SDS	0.02 ((−0.18)−0.21)	−0.01 ((−0.22)−0.18)	0.20 ((−0.01)−0.38)	0.15 ((−0.08)−0.35)	0.52 (0.31–0.68)	−0.28 ((−0.47)−(−0.09))
Hepcidin-25	−0.01 ((−0.24)−0.21)	0.05 ((−0.20)−0.27)	0.16 ((−0.07)−0.38)	0.17 ((−0.04)−0.36)	0.34 (0.16–0.49)	−0.12 ((−0.33)−0.09)

Data represent the correlation coefficient (r) and 95% confidence interval (CI), value < 0.05; value < 0.001 from Spearman’s correlation test. Hb: hemoglobin; Hct: hematocrit; TIBC: total iron binding capacity; TS: transferrin saturation.
