Investigation of Disease Spectrum and Analysis of Risk Factor for Digestive System Diseases of Chinese Army During a Field Training on The Midland of China

Abstract Objective To investigate the digestive disease spectrum of Chinese army servicemen during a field training on the midland and to analyze risk factors of diseases in order to discuss the relative prevention and treatment strategies.Methods Seven troops during a field training on the midland of China were randomly selected by using stratified cluster random sampling methods, all soldiers in that received a questionnaire survey, and then we collected all questionnaires and summarized the soldiers’ digestive system disease spectrum, and discussed risk factors for diseases.Results 3055 valid questionnaires were finally collected,896 soldiers had digestive symptoms, and of all symptoms diarrhea was the most common,whose ratio was 29.3%; 507 soldiers suffered from digestive system diseases, including gastritis, enteritis,digestive ulcer, functional bowel disease, which were more common. By the logistic regression analysis, length of military service time, identity of army officer,length of a field training time,training pressure, chilled abdomen, and defiled food were possible risk factors for digestive diseases.Conclusions During a field training, a healthy and regular diet, the thermal outfit, appropriate decompression of negative emotions and reasonable training time may effectively decrease the risk of digestive diseases, so that to reduce attrition.
