| 摘要: | The heavy workload of policeman is well known in Taiwan. Due to the shortage of manpower, each policeman not only has safety maintenance as routine work, but also has 12-hour shift work every 2 to 3 days. They are always under a high risk of violence and mortality. The high stress causes physiological tension which could interfere with their sleep quality significantly. By using the Pittsburgh Sleep Quality Index (PSQI), Epworth Sleepiness Scale (ESS), and revised Aldoscent Sleep Hygiene Scale (ASHS), we visited 39 police institutes in Taiwan, and collected 124 effective questionnaires from policemen. The subjects we investigated were male, 87.9% were aged between 35 to 55 years old; the percentage of normal range, overweight and obese were 30.9%, 35.0% and 34.1%, respectively. The results showed the sleep quality of the police officers was pretty bad and their average PSQI score was 8.10±3.43. Among the seven index of sleep quality in PS QI, the worst one was the latency of sleeping (1.98±0.86, 3 as total score), and their satisfaction for sleep quality was also low (1.88±0.83, 3 as total score). The score of ESS was 9.40±5.46, which means the policemen were under medium somnolence. The sleep hygiene score was 7.93±3.48. When they were tested the knowledge of sleep, which was translated from the sleep quiz posted on National Sleep Foundation, their average score was 6.11±1.84, which was about 50% of the total (12). We found the sleep quality of the policeman was positively correlated with their sleep hygiene (r = 0.252, P < 0.01) and ESS score (r = 0.200, P < 0.05); while sleep hygiene is also correlated with ESS (r 0.322, P < 0.01). There were no significant differences of PSQI, ESS, and ASHS among policemen’s age and BMI. |
