The relationship between sleep quality and work ability among the employees of isfahan university of medical sciences, Iran, in year 2017

Abstract

Background: Sleep is one of the important physiologic needs in daily life cycle, and a part of quality of life. To design health promotion interventions, we assessed the relationship of sleep quality with job ability. Methods: In this cross-sectional study, the staffs of Isfahan University of Medical Sciences, Isfahan, Iran, selected by simple random sampling method, filled the validated questionnaires of Pittsburgh sleep quality (PSQI) and work ability index (WAI). The first included questions about sleep latency, duration, and efficiency, use of sleeping medication, and daytime dysfunction. The second included physical and mental abilities, diseases, job losses, prognosis of work ability for 2 years, etc. The answers were summated; the scores less than 5 in PSQI showed optimal quality of sleep, and more than 5 showed undesirable quality of sleep. Findings: 120 employees with mean age of 42.28 ± 7.27 years were enrolled. The WAI was high, good, and moderate in 27.8, 41.0, and 31.2 percent of men, and in 28.5, 49.5, and 22.0 percent of women, respectively. The mean score of PSQI was 4.36 ± 2.38. WAI had significant relation with quality of sleep, and the quality of sleep had relation with age. There was not any significant relation between sex, site of work, and marital status with sleep quality and work ability. Conclusion: Sleep quality was relatively low in the staffs, and affected their work abilities; maybe both were established under other causes. However, more researches on causes of low sleep quality, and interventions by time, duration, and relaxation for prevention and treatment of it are suggested. © 2019 Isfahan University of Medical Sciences(IUMS).
