All models were controlled for age and country. Zinc deficiency was defined according to International Zinc Nutrition Consultative Group recommendations: for women 3 cutoffs (<70 μg/dL, <66 μg/dL, and <59 μg/dL) were used depending on whether the blood sample was drawn 1) in the morning when women were known to be in an over-night fasting state, 2) in the morning, with no information on the fasting state or stated to be nonfasting, and 3) in the afternoon when a nonfasting state was presumed, respectively. Deficient iron stores were defined as inflammation-adjusted ferritin concentrations <15 μg/L using BRINDA methodology [Namaste et al. (13)]. aPR, adjusted prevalence ratio; BRINDA, Biomarkers Reflecting Inflammation and Nutritional Determinants of Anemia; WRA, women of reproductive age.
