title: Impact of long-term oral iron supplementation in breast-fed infants.
abstract: OBJECTIVE
  To weigh benefits of oral iron supplements on infant's growth against its potential hazards.
  
  
  METHODS
  248 exclusively breast-fed infants aged 4-6 months were consecutively enrolled and divided into treatment group given iron containing multivitamin (TG = 198) and control group (placebo, PG = 50) given the same multivitamin but without is subdivided according to clinical assessment into group A (well nourished) and group B (malnourished); both were further stratified according to basal blood iron status. Assessment was done after 6 and 12 months with concurrent collection of morbidity parameters (diarrhea and fever). Data were normalized and analyzed using SPSS and Eurogrowth softwares.
  
  
  RESULTS
  After 6 months treatment, weight and length gain was better in TG compared to placebo especially evident in anemic malnourished infants (P 0.05). Morbidity risk was linked to immunologic background of infant; odds ratio for diarrhea and fever was higher in malnourished compared to well nourished (P 0.05) or iron therapy (P for well-nourished non-anemic treatment vs PG > 0.05).
  
  
  CONCLUSIONS
  Oral iron supplementation resulted in better effects on growth velocity of breast fed infants especially those who were initially malnourished and anemic or at least iron depleted, with less marked morbidity than in iron replete infants.
