新兵集训期睡眠质量与自评训练量的关系

目的评价陆军新兵集训期间的睡眠质量及其与自评训练量的关系。方法采用整群抽样方法随机抽取某军区2011年度陆军参训的1389名新兵作为研究对象。用匹兹堡睡眠质量指数（Pittsburgh sleep quality index,PSQI）量表评价新兵集训第1、2、3个月的睡眠质量,通过新兵自评方式评价训练量。采用Kruskal-Wallis H检验、单因素及无序多分类logistic回归分析数据。结果新兵集训第1、2、3个月PSQI平均得分分别为（3.79±2.66）、（4.10±2.65）和（4.28±2.85）;3个月睡眠问题发生率依次为9.1%、10.7%、13.2%,呈现上升趋势（P〈0.05）。城市籍新兵在集训期间有2个月和3个月出现睡眠问题的风险低于农村籍新兵（OR=0.49、0.36）;自评训练量过大为新兵出现睡眠问题的危险因素,其中有1个月、2个月和3个月出现睡眠问题对应的OR值分别为2.24、2.57和2.08。结论部分陆军新兵集训期间存在一定程度的睡眠问题,农村籍新兵和自感训练量过大新兵应作为睡眠干预的重点。

Sleeping Quality and Its Relationship with Self-rated Training Intensity among Recruits in Collective Training

Objective To assess the sleep quality of recruits during collective training and examine its association with self-rated training intensity.Methods Cluster sampling was used to randomly select 1389 recruits of a military region.The recruits＇ sleep quality was assessed with Pittsburgh sleep quality index（PSQI） at the first,second and third month.Training intensity was self-rated by the soldiers using a 0-10 scale.Kruskal-Wallis H test,univariate logistic regression and multinomial logistic regression were used to analyze the data.Results The mean PSQI scores were（3.79±2.66）,（4.10±2.65）,（4.28±2.85） in the first,second and third month respectively.The incidence of sleep problems was significantly increased from 9.1%,10.7% to 13.2% in the three-month training（P〈0.05）.Soldiers from urban areas had lower risk of having sleeping problems at the second and third month than those from rural areas（OR=0.49,0.36）.Soldiers who reported an intolerable training intensity had more sleeping problems than those reporting a tolerable training intensity in the first,second,and third training month（OR=2.24,2.57,2.08）.Conclusion Some recruits have sleeping problems in the collective training.Rural soldiers and soldiers who report an intolerable training intensity are at high risk of having sleeping problems,and should be prioritized when developing sleeping interventions.
