[The study on the correlation between snoring and carotid artery plaques in the elderly population]

To explore the correlation between snoring and carotid artery plaques in the elderly population.

Sixty-seven patients with snoring and 61 healthy volunteers accepted questionnaire on sleep apnea were analyzed in the survey. Multivariate Logistic regression analysis was used to analyze the factors affecting carotid artery plaques.

Among the non-snorers (n = 61), mild snorer (n = 18), moderate snorers (n = 24) and severe snorers (n = 25) groups, the prevalence of carotid artery plaques in four groups were 19.7%, 44.4%, 62.5%, 84.0% respectively. There was statistically significant differences between groups. After multivariable adjustment, the moderate and severe snorers were still risk factors affecting carotid artery plaques, the OR (95% CI) values were 4.378 (1.181-16.225), and 19.572 (3.316-115.528) respectively.

The moderate and severe snoring in the elderly population were relevant to the increased prevalence of carotid artery plaques, and was a risk factor on carotid artery plaques.
