Background and Objective: urinary tract infection (UTI) is a common infectious disease among children. Deficiency in micronutrients such as zinc is believed to play a role in predisposing children to UTI. However, few studies are conducted on this subject. In this study, we aimed to compare the serum zinc level between children with UTI and normal controls.
Methods: In this case-control study, patients suspicious of UTI were assessed by urine culture. The urine sample of the patients who were not toilet trained were gathered using urinary bags and those who were toilet trained were asked to gather the clean catch mid-stream urine. Demographic data, urinary symptoms, type of cultured microorganism, and colony count were recorded. Data were analyzed in SPSS v.22 and P
