Investigation the Quality of Sleep and Life of Industrial Workers with Rotating Shifts

Abstract

Background and Objective: Sleep is a vital need for humans. Industrial workers are among the people who suffer from insomnia and sleep problems due to their rotating shifts. This study aimed to investigate the relationship between sleep quality and the quality of life of industrial workers with rotating shifts. Materials and Methods: This descriptive-cross-sectional study was conducted on 234 industrial workers. Data were collected using a demographic information questionnaire, a short form of the World Health Organization Quality of Life Questionnaire (WHOQOL-BREF), and the Pittsburgh Sleep Quality Index (PSQI). The collected data were analyzed by Pearson correlation tests, independent t-test, and one-way analysis of variance in SPSS software (version 24). Results: The mean and standard deviation of the age of the participants was 31.6±5.7 years. The mean and standard deviation of WHOQOL-BREF and PSQI scores were 66.5±11.3 and 5.8±1.6, respectively. There was a statistically significant correlation between sleep quality and quality of life of the studied workers (r=-0.31 and P<0.001). Individuals in older age groups and more work experience had lower quality of sleep and quality of life. Moreover, females and married people experienced lower quality of sleep and quality of life, compared to males and single people, respectively. Conclusion: Insufficient sleep quality as an effective factor can decrease the quality of life of workers. Since delays in falling asleep and sleep disorders are mentioned as two factors affecting the sleep quality of workers in this research, managers and supervisors should make arrangements to optimize work shifts according to the circadian cycle with proper planning.
