| dc.description.abstract | Many North Americans are affected by mental health disorders (MHD) each year [1,2].
One of the most common MHDs is major depression [1,2]. Major depression has many costs for
the individual and the economy [3–5]. Those with depression are more likely to experience
difficulties sleeping, chronic fatigue, poor physical health, and are at risk of committing suicide
when compared to non-depressed individuals [1,6,7]. The overall risk of mortality is higher
among those with depression than those without [5]. On the economic level, depression is
associated with an increased number of missed days at work (absenteeism) and poor productivity
at work (presenteeism) [5]. Depression is estimated to cost the U.S. economy $36.6 billion per
year in lost worker productivity [5].
Certain occupations put individuals at greater risk for depression than others. One of
these occupations includes long-haul truck drivers. The risk of depression in trucking is higher
when compared to at least 19 other occupational types [1,2,8–11]. Long-haul truck driving
involves delivering freight to distant locations [12,13]. Truckers are usually on the road for
several days at a time [14]. Many also drive overnight and are often alone during their shifts and
their work breaks [14,15]. They also experience tight delivery timeliness and are often paid
based on how far they drive, or how much freight they can deliver [13,16]. The working
conditions of long-haul truckers can result in feels of social isolation and can lead to poor sleep
and fatigue [14,15,17]. Many truckers have also reported that they experience stress due to tight
and unrealistic delivery deadlines, poor road conditions, and violence at work [16]. | en_US |
