Iron status.

	Males (♂)	Females (♀)	♂ vs. ♀
Serum ferritin (μg·L−1)	102.7 ± 54.9	51.4 ± 24.2	p = <0.01*
Transferrin saturation (%)	30.9 ± 15.9	26.7 ± 11.4	p = 0.39
Iron intake (mg)	14.1 ± 7.7	13.4 ± 3.8	p = 0.72
Iron intake density (mg·1,000 kcal−1)	5.95 ± 2.42	6.58 ± 1.71	p = 0.35

Mean ± SD. Male serum ferritin n = 18, Male iron intake n = 19; females n = 20.

^*P ≤ 0.05 is considered significant.

Sub-optimal iron status; serum ferritin (<35 μg·L⁻¹) and/or transferrin saturation (<20%) (44, 45).
