Iron deficiency (ID) defined as plasma ferritin <12 µg (occ). 18-month-old 370 79 acute after aimed analysed and anthropometric associated association been between birth blood c-reactive child childhood children children. chronic cognitive cohort cohort, cohort. danish data delayed denmark describe determine development disease, dnbc, due early exclusion factors ferritin final from had healthy however id in incidence increased infection, infections, is l life longitudinal measurements modified national non-fasting obtained odense of plasma prevalence protein questionnaire questionnaires risk sample samples samples, self-reported size study the this those to unknown. used venous, were with>10 mg/L, twin birth or prematurity. Associations with ID were analysed by logistic regression, adjusting for sex, maternal education, duration of partial breastfeeding and current intake of milk, fish and meat. Overall, 56 children had ID (15.1%). Factors associated with increased risk were exclusive breastfeeding beyond 4 months (OR 5.97, 95%CI [1.63; 21.86]) and no intake of oral iron supplements from 6-12 months (OR 3.99, 95%CI [1.33; 11.97]. Duration of partial breastfeeding and current diet were not associated with ID. In conclusion, the ID prevalence was 15.1%, and both exclusive breastfeeding beyond 4 months and no intake of oral iron supplements from 6-12 months were associated with increased risk for ID in 18-month-old children.
