Association of Iron Depletion with Menstruation and Dietary Intake Indices in Pubertal Girls: The Healthy Growth Study

Table 4

Multivariate logistic regression analysis* examining the association of menstrual status and consumption of certain dietary intake indices with ID in 890^a Greek pubertal girls.

Independent variables	Iron depletion; (serum ferritin < 12 𝜇g/L)
	Odds ratio	95% CI	𝑃 value
Menstrual status
Girls with menses	1.00
Girls without menses	2.57	(1.37, 4.81)	0.003
Calcium intake (mg/day):
<RDA^b	1.00
>RDA	1.28	(0.77, 2.15)	0.344
Poultry (servings/day)	0.19	(0.03, 1.02)	0.074
Fruits (servings/day)	0.99	(0.77, 1.28)	0.956
Packed fruit juice (servings/day)	0.97	(0.67, 1.40)	0.859
Fast food (servings/day)	1.16	(0.14, 1.84)	0.163

∗Adjusted for girl’s age, weight status, and tanner stage.
^aUnderreporters were excluded from the analysis.
^bCalcium recommended dietary allowance (RDA) for children 9–13 years old is 1300 mg/day.
