|Abstract: ||Long distance commercial vehicle driving is an occupation associated with multiple challenges, such as the vast distances travelled, and tight and time dependent delivery schedules. These drivers predominantly work shifts with extended driving schedules, often into or during the night; with monotony on the road often for hours on end, adding to the challenge of staying awake. Obstructive sleep apnoea (OSA) has been found in higher rates in commercial drivers than the general population; and in general drivers OSA can increase the risk of crash by up to seven fold.
The purpose of this study was to estimate the prevalence of previously undiagnosed obstructive sleep apnoea among a population of long distance commercial vehicle drivers, identify risk and protective factors for crash including the use of caffeinated substances for maintaining alertness while driving, and considers these findings in the light of Australian guidelines concerning driving fitness and fatigue management.
The prevalence of previously undiagnosed OSA was 41%, and only 12% of drivers reported a positive Epworth Sleepiness Scale score; further, there was minimal correlation between these groups. Thirty-six percent of drivers were overweight and a further 50% obese; 49% of drivers were cigarette smokers. After adjusting for relevant factors drivers who consumed caffeine to help them stay awake were 63% less likely to crash than drivers who did not take caffeinated substances.
It remains evident that long distance commercial vehicle drivers suffer a difficult work environment and less than ideal health; a multitude of factors interplay to confer increased risk of crashing, which adds significant burden to all road users. There are solutions available to mitigate these risks; however, these will work best where there is close interaction and collaboration between regulatory bodies, occupational health and safety groups, road safety stakeholders, medical professionals and importantly the drivers themselves.|
