Abstract: Objectives: The objective of the studywas to describeworking and sleep conditions and to assess howsleep
opportunities are associated with obtained sleep and alertness, in a sample of long-haul bus drivers working
with a two-up operations system.
Methods: Measures of subjective sleep and sleepiness, actigraphy, circadian temperature rhythm, and psychomotor
vigilance tasks were obtained from a sample of 122 drivers fromArgentina. Variables were compared
between high and low fatigue risk groups, which were formed using a median split of a fatigue risk
score. The score was calculated based on drivers' total working hours, maximum shift duration, minimum
short break duration, maximum night work per seven days, and long break frequencies.
Results: Considering a standardized one-day period, sleep in the bus accounted for 1.9±0.1 h of total sleep
(57±1% efficiency), sleep at destination for 1.6±0.2 h of total sleep (90±1% efficiency), and sleep at home
for 3.8±0.2 h of total sleep (89±1% nap efficiency and 90±1% anchor sleep efficiency). In drivers exposed
to high-risk working schedules, the circadian temperature rhythm was weaker (lower % of variance
explained by the model) (22.0±1.7% vs. 27.6±2.0%, p <0.05) and without a significant acrophase.
Conclusions: Drivers obtained a total amount of weekly sleep similar to the recommended levels for adults,
but distributed at different locations and at different times during the day. High-risk working schedules
were associated with disruption of circadian temperature rhythms. These results point out to the need of
the implementation of shift-work scheduling strategies to minimize sleep misalignment and circadian
desynchronization in long-haul bus drivers. |
