Snoring Statistics
 

These brief stats and research snippets will be collected here as we come across them.

Prevalence of snoring

bullet
30% of those over age 30 snore, rising to 40% in middle-age.  (Source: British Medical Journal, 1997)
bullet
Two-thirds of partnered adults say their partner snores, while 6 out of 10 of all adults (59%) say they snore. (Source National Sleep Foundation's 2005 poll)
bullet
Male:Female ratio = 2:1 with the gap closing after menopause (Souce:Vancouver sleep and Breathing Center)
bullet
5.6% of children are habitual snorers.   (Source: Pediatrics Nov, 2001)

Prevalence of sleep apnea:

bullet
May be present in 20-40% of the adult population that experience snoring.  (National Sleep Foundation)
bullet
Affects 9% of men and 4% of women between the ages of 30 and 60 (Source unclear, cited in BBC News story)
bullet
Present in 0.7% to 10.3% of children ( Pediatrics, Vol. 109 No. 4 April 2002, pp. e69)

Risks of sleep apnea:

bullet
An individual with untreated apnea (OSA) is up to 4 times more likely to have a stroke and 3 times more likely to have heart disease.  (National Sleep Foundation)
bullet
Patients with untreated apnea run a 3% risk of stroke and heart attack.  Treatment with CPAP was found to lower blood pressure and reduce the risk of stroke by 20% (The Lancet 2002; 359: 204-210)
bullet
About one half of patients who have essential hypertension have obstructive sleep apnea, and about one half of patients who have obstructive sleep apnea have essential hypertension.  ( Am Fam Physician 2002;65:229-36)
bullet
People suffering from sleep apnea are six times more likely to be involved in a car crash (as a result of drowsiness) than those without sleep disorders. ( New England Journal of Medicine , March 18, 1999)
bullet
The National Highway Traffic Safety Administration (NHTSA) estimates that each year drowsy driving "is responsible for at least 100,000 automobile crashes, 40,000 injuries, and 1,550 fatalities."  (National Sleep Foundation)

How many women snore?

bullet
19% (Source unknown, cited by researchers conducting a study of 24 snoring women).  

Factors associated with snoring in women:

bullet
Snoring women are significantly shorter and heavier than non-snoring women, with a greater incidence of nasal problems . (Ann Otol Rhinol Laryngol 1998:227-231)

Risks associated with snoring in women :

bullet
Hypertension and heart disease (CardiacConsult Review 1999: 2:2) 

The sound of snoring

bullet
Almost 85 percent of snorers exceed 38 decibels of sound, which is equivalent to the noise of light highway traffic. Men snore louder than women. (Research by HealthEast and the Stanford Sleep Disorders Clinic, cited here)
bullet
But snoring apparently doesn't cause hearing loss.  A study of 219 sleep disorder patients in Canada found that the loudness of their snoring was not related to their hearing acuity. ( Am J Respir Crit Care Med 1999: 159)

Your long-suffering partner

bullet
The partner of an apnea patient loses about an hour of sleep due to partner's snoring -- inferred from fact that CPAP use increases partner's sleep an hour per night. (Mayo clinic study, cited here)
