Relationship Between Sleep Quality, Obstructive Sleep Apnea and Sleepiness During Day With Related Factors in Professional Drivers.

One of the important reasons for accidents is sleepiness.With this description, the sleep disorders are associated with health and mortality, and not only affect the person but also the family and the whole society. Aim of this study was assessing of relationship between Sleep Quality, Obstructive sleep Apnea and Sleepiness during day with related factors in professional drivers. This was a cross-sectional study measuring correlation between sleep quality questionnaire (Pittsburgh Sleep Quality Index or PSQI), Epworth Sleepiness Scale (ESS) and Stop Bang questionnaire (STOP BANG).the appropriate sample size to achieve a 95% confidence level was 943 people. The study population was chosen among qualified drivers using a convenience sampling method that took place over 12 months duration. Exclusion criterion consisted of the presence of a physical or mental disability. Data analyzed by software SPSS, version 15. In this study, all drivers were men with mean of age 36±9/5 year (minimum 22 year and maximum 72 year), 799 (84.7%) were married, 535 (56.7%) had high school education. Also, 96.4 % of drivers had undesirable sleep quality, 25.8% obstructive sleep apnea and 6.8% abnormal sleepiness during day. Multiple linear regression test showed, Score of STOP-Bang was correlated with smoking (OR (β)=0/2, P=0.006) and history of hurt disease (OR (β)=0.95, P=0.003), shift work (OR (β)=0.19, P=0.006) more probability. Moreover, PSQI was statistically significant with shift work (OR (β)=0.44, P=0.02), smoking (OR (β)=0.98, P=0.001), history of pulmonary disease (OR (β)=3.58, P=0.009) more probability , and ESS was statistically significant with smoking (OR (β)=0.64, P=0.007) and history of pulmonary disease(OR (β)=2.82, P=0.006), shift work (OR (β)=0.59, P=0.008) more probability. In our study, according to the results, it should be planning to reduce the driving time in day and night and also it are recommended short breaks during driving. It is suggested the more widespread and prospective studies, as well as informing the drivers about the benefits of proper sleep and annual checkup drivers of health.
