Prevalence of Urinary Tract Infection and Associated Microorganisms in Iran; A meta-Analysis Study

Background and objective: This study aims to evaluate the prevalence of UTI and determine the most prevalent microorganisms in Iran by using meta-analysis. Materials and Methods: By use searching the keywords in information Databases such as SID, Magiran, Iranmedex, Science direct, PubMed and Google Scholar, a total number of 40 papers were selected between 1996-2011 years, based on inclusion criteria in this study. All papers were enrolled to Meta analysis after qualitative control by using random effect model. Heterogeneity between studies was assessed by I-Square index, and then data was analyzed by using R-software (Version 2.11.1) and STATA software (version 10). Eleven papers were recognized eligible to be enrolled Meta analysis from 40 selected papers. Totally, 66448 individual was studied. Findings: The prevalence rate of UTI in Iran was 13.3% (CI95%; 7.8-17.8). E. Coli with prevalence of 62.1% (CI95%; 55.4-68.9) was the most prevalent microorganism and Enterobacter with prevalence of 2.8% (CI95%; 1.8-3.8) were the lowest isolated microorganisms. Health education, prescription of the best antibiotics based on urine culture, and avoidance from overdose of antibiotics and self medication are recommended In order to reduce the prevalence of UTI.
