Background: Few studies examined the risk factors of asymptomatic bacteriuria, showing contradictory results.Our study aimed to examine the association between different clinical and laboratory parameters andasymptomatic bacteriuria in internal medicine patients.Materials and methods: 330 consecutive hospitalized subjects, asymptomatic for urinary tract infections (UTIs),underwent to microscopic examination of urine specimens. 100 subjects were positive for microscopicbacteriuria and were recruited into the study. At the quantitative urine culture 31 subjects of study populationwere positive while 69 subjects were negative for bacteriuria.Results: The analysis of clinical characteristics showed that the two groups of subjects (positive and negativeurine culture for bacteriuria) were significant different (p b 0.05) about obesity (76.7% vs 42% respectively),metabolic syndrome (80.6% vs 44,9%), cholelithiasis (35.5% vs 13,2%) and iron deficiency anemia (80.6% vs53,6%). The univariate analysis showed that only obesity, cholelithiasis and iron deficiency anemia werepositively associated with positive urine culture for bacteriuria (Odds Ratios [OR] = 3.79, p = 0.0003;OR = 2,65, p =0.0091; OR = 2.63, p = 0.0097; respectively). However, the multivariate analysis bylogistic regression showed that only obesity and iron deficiency anemia, independently associated withpositive urine culture for bacteriuria (OR = 3.9695, p = 0.0075; OR = 3.1569, p = 0.03420 respectively).Conclusions: This study shows that obesity and iron deficiency anemia are independent risk factors forasymptomatic bacteriuria.
