Abstract
ObjectiveTo investigate the sleep quality and daytime sleepiness between naval afloat and ashore personnel.
MethodsSleep quality and daytime sleepiness of 50 naval afloat personnel and 50 naval ashore personnel were evaluated by using the Pittsburgh Sleep Quality Index (PSQI) and the Epworth Sleepiness Scale (ESS).
ResultsThe incidence of sleeping disorder among the afloat or shipboard naval personnel accounted for 57.14%, which showed statistical significance as compared with 29.17% of the ashore personnel (P<0.05). Statistical significance could be seen in sleep quality, sleep latency, sleep time, sleep efficiency, sleep disorder as well as daytime dysfunction, when comparisons were made between the 2 groups (P<0.05). The incidence of daytime sleepiness in the naval afloat personnel was 61.22%, which was of statistical significance, as compared with 27.08% of the ashore personnel (P<0.05).
ConclusionsThe sleep quality of the afloat naval personnel was poorer than that of the ashore personnel, while daytime sleepiness was severer.
