We have performed a study assessing the prevalence of sleep-disordered breathing ln a large US trucking company using a validated portable monitor (MESAM-4) and a validated symptom questionnaire. Three hundred eighty-eight drivers with a mean age of 36 years filled out the questionnaire. One hundred fifty drivers with a mean age of 35 years spent the night at the terminal hub where they underwent monitoring for identification of sleep-disordered breathing. The drivers also had blood pressure recorded while awake, seated and after 15 min of quiet rest. Seventy-eight percent of the drivers had an oxygen desaturation index (ODI) >5 per heur of sleep; 10% had an ODI >30 per hour of sleep. There was a significant difference in the body mass index (BMI) between drivers with ODI < 5 drivers with ODI >5 (25.7 ±6.0 kg/m2 in driver,with ODI <5 vs 29.0±6.3 kg/m2 in drivers with ODI > 5, p<0.00P. Sixteen percent of all drivers tested were hypertensive. Twelve percent were unaware of their hypertension. Hypertensive drivers were significantly more over
weight, slept more restlessly took mure naps, and woke up mure frequently during the night. About 20%, of drivers presented symptoms indicating very regular sleep, disturbances.
Drivers who lhad been with the company for more than 1 year were more likely to present daytime fatigue, daytime fatigue,daytime tiedness, un restorative sleep, hypertension, and higher BMI. Long-haul truck drivers have very
irregular sleep/wake schedules iand a high prevalence of sleep-disorderd breathing. Chronicsleep/wake disruption and partial prolonged sleep deprivation may worsen sleep-disordered breathing. This combination of problems may impact significantly on the daytime alertness of truckers.
