Objective No related training experience, no systematic training before military training, psychological negative emotions(tension and anxiety) and low frequency of physical activities(less than three times a week) have been considered as crucial risk factors of high intensive military training induced acute kidney injury.This paper aims to discuss whether these risk factors can be used for screening high risk groups.Methods Soldiers were divided into 5 groups based on the questionnaire survey:Group1 had no risk factor, Group2 had 1 risk factor, Group3 had 2 risk factors, Group4 had 3 risk factors, and Group5 had 4 risk factors.Urine samples were collected after 6 h and 24 h of 5 km armed military training.Kidney injury indicators were compared such as urine protein, urine occult blood test, urine micro-albumin ( mALB) , urine N-acetyl-β-D-glucosaminidase( NAG) among different groups.Results As the risk factors increased, the incidence of positive urinary protein 6 h after training increased (x2 =101.8,P<0.001),and the levels of mALB and NAG of urine samples were elevated as well.The analysis among moderate and high risk groups(Group3-5) showed that the levels of mALB and NAG of urine samples 24 h after training increased with the number of risk factors.The mean value of these injury indicators reached to the maximum in Group 5.Conclusion No related training experience, no systematic training before military training, psychological negative emotions( tension and anxiety) and low frequency of physical activi-ties(less than three times a week) are independent risk factors of high intensive military training induced acute kidney inju-ry,which can be used for screening high risk individuals during training.
