Table 2. Associations between iron deficiency anemia* and short sleep duration.^† Data are presented as OR (95%CI) for the anemia group in comparison to those without the anemia group. Logistic regression models are adjusted for family income, education, gender, and birth body mass index.

	OR (95%CI)	p-value
Unadjusted model	3.33 (0.90–2.22)	0.06
Adjusted model	4.02 (1.02–15.76)	0.04

BMI: body mass index; OR: odds ratio; CI: confidence interval. *Anemia groups were defined as follows: with anemia group: hemoglobin <11 g/dL at birth and/or at 6 months of age and without anemia group: hemoglobin ≥11 g/dL at birth and at 6 months of age; ^†Sleep duration groups were defined as follows: not short-sleep group ≥10 h at 3, 6, and 12 months of age and short-sleep group <10 h at 3, 6, and/or 12 months of age.
