Abstract:
PURPOSE: The normal flora, which was suggested to prevent infection, is acquired first from the birth canal and develops by dietary factors. Here presents a case-control study, aimed to evaluate the postnatal acquisition factors relating to the achievement of the normal flora in infants with urinary tract infection (UTI). METHODS: 115 UTI infants, admitted at Ewha Womans University Mokdong Hospital from 2004 to 2005 and 116 age-matched control infants, who had visited well baby clinic, were evaluated. The suggested postnatal acquisition factors of the normal flora such as vaginal delivery, breast feeding, probiotics and yogurt intake and their relationship with UTI were evaluated. RESULTS: The rate of vaginal delivery was 50%(58/115) in UTI infants, which was not significantly different from 60%(69/116) in control infants(P>0.05). In the infants with UTI, the feeding pattern(breast milk 19%, mixed 26%, formula 55%) was significantly different from that(44%, 19%, 37%) in control infants(P<0.05). This significant difference was shown only in infants less than 6 months of age, but was not in infants over 6 months of age. The rate of probiotics intake in UTI infants was 4%(4/115), which was significantly lower than 27% (32/116) in control infants(P<0.05). The rate of regular intake of yogurt in UTI infants over 6 months of age was 27%(6/23), which was not significantly different from 35%(8/23) in control infants(P>0.05). The odds ratios of breast feeding and probiotics intake against UTI were significantly low as 0.30 (95% CI 0.17-0.55)(P<0.01) and 0.03 (95% CI 0.01-0.07)(P<0.01). CONCLUSION: The significantly lower rates of breast feeding and probiotics intake in UTI infants suggest that these dietary factors might have preventive effects in infants with UTI.
