The primary objective of this study was to determine the prevalence of iron deficiency anaemia (IDA) in hospitalised 6- to 24-month-old infants in rural versus urban settings. The secondary objective was to determine associated risk factors in rural versus urban settings.

A 6-month prospective multicentre cross-sectional study was conducted in paediatrics departments of three Lebanese hospitals. Preterm to term infants aged 6–24 months were included. Infants with blood disorders, chronic infections, congenital immunodeficiency and mental or congenital growth retardation were excluded. Incidence of IDA was assessed using haematologic laboratory values, while risk factors were assessed using questionnaires addressed to infants' caregivers. For data analysis, P values, chi-squared and logistic regression were used.
