Abstract：Objective To explore changes of stress of new recruits trained in closed environment, and the influence of stress on cognitive function.Methods Ninety-seven male new recruits of a certain army were chosen as the study group who had finished the routine training for new recruits and were taking the mission of training in closed environment for the first time. Forty-six male veterans trained in closed environment at the same time served as the control group who had been in army service for more than two years and had trained in closed environment for no less than twice. With the week before training and the training period as the observational period, ELISA was employed to monitor salivary cortisol(SC) concentrations of subjects successively. With the second week of training as the observational section, MoCA-BJ was employed to assess their cognitive function. The SC concentrations and MoCA-BJ scores were compared between the two groups, and the relevance of SC concentrations to MoCA-BJ scores was analyzed respectively.Results Ninety-two men were admitted to the study group, and 43 men were admitted to the control one. Compared with the control group, SC of the study group increased earlier, peaked higher, lasted longer, and its SC concentrations of the first three weeks after the training were higher than those in the control group significantly (P＜0.01). In the second week, the total MoCA-BJ score in each group of the study group (22.87±1.65) was lower than that of the control one (27.32±1.53), and the difference was statistically significant (t=13.72,P＜0.01). SC concentrations of the study group were correlated negatively with MoCA-BJ scores statistically(rs=-0.426,95% CI:-0.511--0.331,P＜0.01),while SC concentrations of the control group were uncorrelated with MoCA-BJ scores(rs=0.236,P＞0.05).Conclusion During training in closed environment, the new recruits show stronger stress than the veterans so the prevention and treatment ofcognitive function should be paid more attention.
