ABSTRACT

Objective To investigate the sleep quality and life quality of soldiers in a navy warship troop, and to explore the correlation between sleep quality and life quality and their influencing factors. Methods Random cluster sampling method was used to select navy soldiers from a navy warship troop. The subjects were surveyed by Pittsburgh sleep quality index (PSQI) scale and World Health Organization Quality of Life-Brief scale (WHOQOL-BREF). Results A total of 160 questionnaires were sent out and 154 valid questionnaires were returned (response rate 94.6%). Of 154 subjects, 31.8% (49/154) had good sleep quality, 53.2% (82/154) had moderate sleep quality, and 14.9% (23/154) had poor sleep quality. The soldiers with good sleep quality had significantly higher scores than those with poor sleep quality in physical, psychological, social and environmental domains of life quality (P0.05 or P0.01). Total PSQI score and most of scores of 7 parts of life quality, including subjective sleep quality, sleep latency, sleep time, sleep disturbances, hypnotic drugs, daytime dysfunction and sleep efficiency, were negatively correlated with the scores of 4 domains of sleep quality. There was significant difference in sleep latency of the subjects with the educational level of junior high school, senior high or polytechnic school, junior college, undergraduate college, or graduate degrees (F＝5.368, P0.01), and the subjects with junior college degree had the highest score of sleep latency, while those with undergraduate college degree had the lowest score of sleep latency. Soldiers had a higher score of sleep latency than the officers (t＝2.069, P＝0.040). There was significant difference in the social domain scores of life quality between navy servicemen with military service time 8 years, 3-8 years and ≤2 years (F＝3.401, P＝0.036). Officers had a higher score of social domain than soldiers (t＝－2.093, P＝0.038). Conclusion The sleep quality of navy servicemen should be improved. Improving sleep quality can effectively ameliorate life quality. The sleep quality and life quality of navy servicemen are related to educational levels, work categories and military service time. The corresponding psychological and behavioral intervention should be carried out according to the characteristics of different personnels.
