海军某部驻岛官兵驻岛时长与睡眠质量关系的调查

Investigation on relationship between length of stay and sleep quality among naval officers and soldiers stationed on island

目的探讨海军某部驻岛官兵的睡眠质量及其与驻岛时长的关系。方法 2019年7-8月采用整群抽样方法,使用自编人口学问卷和匹兹堡睡眠指数(PSQI)量表对海军某部驻岛官兵进行调查。结果 (1)在423名海军驻岛官兵中,累计驻岛时间为326.78天,累计上岛次数为3.34次。PSQI总分为7.21±3.44。其中42.3%的官兵PSQI总分>7,睡眠质量较差。(2)累计在岛时长(天)与睡眠时间、日间功能以及PSQI总分呈显著正相关(r=0.114、0.128、0.109,均P<0.05),累计登岛次数与睡眠时间、睡眠效率、日间功能以及PSQI总分呈显著正相关(r=0.144、0.099、0.110、0.143,均P<0.05)。(3)回归分析发现,累计上岛次数越多,睡眠质量越差(β=0.109,P<0.05)。结论驻岛官兵的睡眠质量总体较差,并且与驻岛时长呈正相关。应采取有针对性的措施预防和改善守岛官兵的睡眠问题。

Objective To investigate the relationship between sleep quality and length of stay among naval officers and soldiers stationed on island. Methods The naval officers and soldiers stationed on island were collected by the cluster sampling method from July to August 2019,and were measured by self-designed demographic questionnaire and the Pittsburgh Sleep Quality Index(PSQI). Results ①Among the 423 military members on the island,the total number of days stationed on the island was 326.78 days,and the cumulative number of visiting to the island was 3.34 times. The PSQI score was 7.21 ±3.44 and 42.3% military members had poor sleep quality(PSQI score>7). ②The total number of days on the island(d) was significantly positively correlated with sleep duration,daytime function and PSQI total score(r=0.114,0.128,0.109,all P<0.05). The cumulative number of landing on the island was significantly positively correlated with sleep duration,sleep efficiency,daytime function and PSQI total score(r=0.144,0.099,0.110,0.143,all P<0.05). ③Regression analysis found that the greater the number of visiting to the island,the worse the sleep quality (β=0.109,P<0.05). Conclusion Military members on the island have poor sleep quality and it is positively related to the duration of the officers and men stationed on the island. Some measures should be taken to prevent and improve the sleep problems of island guards.
