Violent snoring is perhaps not a problem affecting one's partner alone, but could carry heavy social costs.
"Snoring, sleep apnoea, and obesity-related respiratory difficulties are fairly common disorders that affect a large proportion of the population," says Poul Jennum, Professor of Clinical Neurophysiology at the Center for Healthy Ageing at the University of Copenhagen Faculty of Health Sciences. He is head of the Danish Centre for Sleep Medicine, Glostrup Hospital, which treats patients from all over the country.
"Previous studies show that these disorders seriously affect quality of life, and our new studies show that people who snore violently, and particularly those who suffer from sleep apnoea, narcolepsy and obesity-related respiratory difficulties, are more frequently in contact with the health service than others; they take more medicine, they are unemployed more often and have lower average incomes than healthy people- The more serious their disorders, the greater the socio-economic costs."
The socio-economic consequences are present up to eight years before patients are finally diagnosed with sleep apnoea and obesity-related respiratory difficulties. The costs include more frequent visits to the doctor, hospital admissions or medicine use, and indirect costs by way of lost labour, lower earnings and greater unemployment. The researchers also noted that the patients were more likely to be on welfare than healthy subjects, and more likely to be on prescription medicines subsidised by the state.
In addition patients who suffer from snoring, sleep apnoea or obesity-related respiratory difficulties received extra welfare payments.
"Our study is the first to look at the actual socio-economic cost of the three disorders," Professor Jennum continues. In the last couple of years he has conducted several studies into the socio-economic costs of sleep disorders such as narcolepsy, where researchers found higher medicine consumption, more hospital admissions, and 30 per cent greater unemployment when the disease was undiagnosed and untreated. So there is plenty of potential for ensuring earlier intervention, diagnosis and therapy.
"In the last few years we have become better at diagnosing and treating sleep apnoea and obesity-related respiratory difficulties. This may help our patients, because we know that there are lots and lots of people out there who are terribly tired in the daytime without being diagnosed and without knowing why. If you sleep badly at night for long periods at a time this may be due to various sleeping disorders, most of which we can treat nowadays. So it is important for people with sleep disorders to get in touch with the health service; otherwise their health, education, ability to work, and thereby their finances may be affected."
