Objective:
To study the prevalence of snoring and obstructive sleep apnea hypopnea syndrome (OSAHS) in drivers in Chengde city.
Methods:
The prevalence of snoring and OSAHS in drivers was investigated by a questionnaire, and some of the drivers with more severe snoring were also evaluated by polysomnographic study.
Results:
Among the 718 investigated drivers, never snoring was reported in 68.3% (490/718), mild snoring in 31.7% (228/718), and moderate and severe snoring in 16.6% (119/718). The prevalence of snoring increased with age. The prevalence of snoring was higher in males (33.6%) than in females (15.3%). When their knowledge of snoring was evaluated, 43.2% (310/718) thought snoring was not a disease, 16.7% (120/718) considered snoring as a disease but needed no treatment, 40.1% (228/718) considered it as a disease and needed treatment but only 1 had ever received treatment. If AHI > or = 5/h was used as the diagnostic criteria, the prevalence of OSAHS in the drivers was 12.3% (28/228); and if Epworth Sleepiness Scoring (ESS > or = 9) was combined, the prevalence of OSAHS was 4.1% (9/228).
Conclusion:
The prevalence of snoring in drivers was 31.7%, and the prevalence of OSAHS was 4.1%. Drivers need to be informed of the potential harm of OSAHS on their work.
