It may lead to renal dysfunction or death as a result of oligohydramnios or respiratory failure. Objectives: This research had aimed to find a probable related link between the MCDK and epidemiologic factors. Patients and Methods: A total of 120 children were evaluated in this case-control research. The case and control groups included 60 children with MCDK and 60 children without MCDK, respectively. Examinations, interviews and questionnaires carried out by the project and diagnosis by a physician. We analyzed our results data using chi-square and student t test as appropriate. Results: The result of this study did not show significant relationship between epidemiological factors such as age, place of residence for families, sex, family education/occupation/ income, body mass index (BMI), stunted growth, slow growth, good growth, milk intake, water intake, failure to thrive (FTT) and MCDK. Conclusion: This study showed that epidemiological factors do not have a significant effect on the occurrence of MCDK disease.
