摘要
objective: to determine the prevalence of risk factors for obstructive sleep apnea syndrome in interstate bus drivers. methods: this study involved 262 professional interstate bus drivers employed by a brazilian company headquartered in the federal district. the drivers were evaluated using a questionnaire designed to assess respiratory sleep disorders, the epworth sleepiness scale, test of sustained attention, test of divided attention and anthropometric measurements. results: body weight was found to be above the ideal in 68% of the drivers evaluated, 34% of which had a neck circumference = 42 cm. during the study period, the drivers reported using tobacco (27%), cola-based soft drinks (55%), alcohol (65%) and coffee (88%). the epworth sleepiness scale score was = 10 points in 28%. snoring was reported by 36%, sleep apnea by 5%, a sensation of suffocation during sleep by 12%, restless sleep by 29% and drowsiness while driving by 48%. there were 42% who had been involved in transit accidents, 7.6% of which were attributed to hypersomnolence. those scoring higher than 10 of the epworth sleepiness scale presented lower levels of sustained attention. in addition, a reduction in divided attention was found to correlate with greater daytime sleepiness and larger neck circumference. conclusion: the rate of stimulant use found in the group of drivers evaluated is alarming. the high prevalence of daytime sleepiness indicates that attentiveness is reduced in this population.
