Factors Effective in Sleeping Quality of Employees Presenting to the Center for Occupational Medicine at Gonabad University of Medical Sciences for Conduct Periodic Examinations

Background: The prevalence of sleep disorders in the general population is between 26.4% and 39.4% in Asia, which has increased in Iran in recent decades. Low sleep quality and reduced sleep hours result in work impairment and physical and mental illnesses. This study aimed to improve sleep quality and determine the factors affecting the quality of sleep. Materials and Methods: This cross-sectional study was performed in 2018 among 243 employees presenting to the Center for Occupational Medicine at Gonabad University of Medical Sciences. Demographic data such as age, shift work and education level were asked of the staff. Weight, blood pressure, height and waist circumference were measured. The sleep quality score was extracted by completing the Pittsburgh Sleep Quality Index. Glucose, triglyceride and cholesterol were also measured. Logistic regression analysis was performed. Significance level was set at 0.05. Results: Among 243 men studied, 99 men (40.7%) had low sleep quality and 126 men (51.9%) reported sleeping less than seven hours a day. age (p=0.021) and waist circumference (p=0.036) and shift work had a direct effect while education had a reverse effect on the quality of sleep. Fasting blood suger, cholesterol, triglesride, body mass index did not have a significant effect on sleep quality. Conclusion: Low sleep quality and inadequate sleep hours causes physical and psychological complications, which mandates planning and training to reduce factors affecting low sleep quality.
