Background: The prevalence of chronic kidney disease (CKD) is rapidly increasing due to lifestyle changes. Therefore, the current study was aimed to determine the prevalence of CKD in Iran army ground forces. Methods: This cross sectional study was conducted in 2017 on 1,800 health records of the army ground forces of the Islamic Republic of Iran that were referred to four medical centers of the in different cities. Moreover, healthy people over 20 years of age entered the study. Subject with kidney disease and individuals without a complete medical record were excluded. After recording the demographic data and evaluating pathological criteria such as GFR, blood pressure, cholesterol, uric acid, creatinine, proteinuria, FBS and RBC in urine, their relationship with different stages of CKD was then evaluated. Results: subjects consist of 1726 men and 74 women (1800 cases), aged 19–65 years with an average age of 35.47 ± 7. 41 years were included in the study. With regard to the classification, 1597 subjects (89.5%) were assigned in to normal group, followed by 105 subjects with mild stage (5.9%; Stage I), 70 (3.9%) with mild CKD (Stage II) and 11 subjects (1.1%) have moderate CKD (Stage III). After adjusting data, none of the subjects had sever CKD and end stage CKD. Statistical analysis revealed that the age, weight and BMI were significantly higher in patients with CKD (especially Stage I). Moreover, Uric acid, HDL, cholesterol, FBS, Red Blood Cells (RBC) in the urine and also the frequency of proteinuria were significantly higher in patients suffering from CKD (p<0.05). Conclusion: Unhealthy clinical conditions of the body such as blood pressure, blood glucose, cholesterol and high weight, and risk factors such as proteinuria, age, and RBC in the urine are significantly related to CKD.
