Analysis of Characteristics and Risk Factors of Eye Diseases Among Officers and Soldiers Stationed in Tibetan Plateau
Objective To investigate the characteristics and risk factors for eye diseases among military personnel in Tibetan plateau.Methods The officers and soldiers emergency entry Nyingchi stationing(emergency entry training group,n=269)and permanent stationed in Nyingchi(permanent stationing group,n=191)during the same time from July 2022 to January 2023 were selected as the research objects.After 1 month of adaptability training,the officers and soldiers of the emergency entry training group were transported to various stations on the plateau(altitude 3000 m)train-ing for a half year(180 days)from the plain station with an average altitude of 100 m after 4 days of railway transporta-tion,and divided into early training(88 days)and late training(92 days);the officers and soldiers in permanent statio-ning group were officers and soldiers of garrison units in Nyingchi region,and all military personnel were in active serv-ice.A total of 460 subjects were studied,including 356 patients with altitude eye disease and 104 patients without altitude eye disease.The differences of general data and the incidence of eye diseases of officers and soldiers in plateau were ana-lyzed,and the risk factors and cumulative risk rate were investigated by Cox proportional risk regression model.Results There were statistically significant differences between officers and soldiers with and without altitude eye disease in differ-ent age,occupation,region,altitude level,stationing form,altitude time,daily near-eye usage time,and nightly sleep duration and smoking status(all P＜0.05).There was significant difference in the number of infected and non-infected eye diseases between the two groups(P＜0.05).There was significant difference in the average daily incidence of eye dis-eases among officers and soldiers in different garrison states(P=0.001).The Cox regression analysis revealed that sta-tioning form,occupation,altitude time,altitude level,daily near-eye usage time,and nightly sleep duration were inde-pendent risk factors for high-altitude eye diseases and their onset times(P＜0.05).Conclusion The distribution and types of ophthalmopathy among the mili-tary personnel on the Tibetan plateau are characteristic(predominantly infectious,dry eye and allergic diseases),which are affected by the unique factors of the plateau,eye habits and sleep.
