Both cases and controls were dividedaccording to the type of feeding during first 6 months of life into three groups: Exclusivebreastfeeding, bottle feeding and mixed feeding.RESULTS:Infants exclusively breastfed for 6 months, shown to have a lower risk of UTI 12% than partiallybreastfed 68% or bottle fed peers 20%. This protective effect after fixation of other variables (Pvalue=0.0001). The study also showed that lack of circumcision in male infants, having a previoushistory of UTI and use of antibiotics inappropriately were significant risk factors for UTI in infants.CONCLUSION:This study showed a protective role of breastfeeding on UTI in infancy.
