[Sleeping disorders and injury prevention of occupational or domestic accidents].

Obstructive sleep apnoeas affect a significant proportion of the middle-aged population. They are due to the closure of upper airways during sleep and cause fragmented sleep, which leads to excessive daily drowsiness. Sleepiness due to apnoea is acknowledged by 10 to 30% of subjects in epidemiological surveys. It impairs vigilance, and therefore represents a risk factor for traffic, domestic and work-related accidents. In the case of domestic accidents, a study shows an increased number of accidents have been reported by subjects with apnoeas; a second study reports the reduction in the frequency of such accidents after receiving appropriate treatment. Subjects suffering from sleep apnoeas also have a higher frequency of accidents at work. Workers with persistent daily drowsiness were also found to have a higher rate of absenteeism as well.
