New research shows that snoring is not the sole domain of men.
"We found that although no difference in snoring intensity was found between genders, women tend to under-report the fact that they snore and to underestimate the loudness of their snoring," said lead investigator Dr Nimrod Maimon. He is head of internal medicine at Soroka University Medical Center in Be'er Sheva, Israel.
"Women reported snoring less often and described it as milder," Maimon said in a news release from the American Academy of Sleep Medicine.
The study included more than 1 900 people, average age 49, who were referred to a sleep disorders centre.
Snoring was found in 88% of the women, but only 72% reported that they snore. Both rates were about 93% in men in the study group.
Among people who snored, the average maximum loudness was 50 decibels among women and 51.7 decibels among men. While 49% of the women had severe/very severe snoring, only 40% rated their snoring at this level, the researchers found.
The study authors noted that there is a social stigma associated with snoring among women, so women may not be truthful when asked about snoring. More troubling, this may contribute to the underdiagnosis of obstructive sleep apnoea in women.
Sleep clinics for a sleep study
Snoring is a common warning sign for obstructive sleep apnoea, in which the upper airway repeatedly collapses during sleep. Left untreated, sleep apnoea can lead to high blood pressure, stroke, heart disease and other health issues.
"The fact that women reported snoring less often and described it as milder may be one of the barriers preventing women from reaching sleep clinics for a sleep study," Maimon said.
When screening women for obstructive sleep apnoea, health care providers should consider other factors in addition to self-reported snoring, he suggested.
For example, women with sleep apnoea may be more likely than men to report other symptoms, such as daytime fatigue or tiredness.
The study was published online recently in the Journal of Clinical Sleep Medicine.
