PURPOSE: Snoring has a high prevalence with some studies reporting 28% of women and 44% of men to be habitual snorers. Obstructive Sleep Apnea, a more severe form of sleep-disordered breathing, is associated with a higher prevalence of conditions such as coronary artery disease and stroke. Since the association between snoring and other medical conditions has not been well delineated, we hypothesized that snoring may share some of these risks

METHODS: The 2012 Behavioral Risk Factor Surveillance System (BRFSS) survey addressed demographic factors, comorbidities, and the snoring status of adult respondents in 4 participating states, namely Alaska, Nevada, Oregon, and Puerto Rico. Data from 17,492 respondents was analyzed comparing comorbidities between snorers and non-snorers. A chi square test for categorical variables and t-test for continuous variables defined correlations between comorbidities and self-reported snoring. Logistic regression analysis was used to adjust for demographic factors and smoking status to study the association between comorbidities and snoring. Statistical analysis was performed using statistical package SAS 9.4 for Windows (SAS Institute Inc., Cary, NC, USA.).

RESULTS: Snoring was reported in 53.5% of respondents. Snorers were older in age as compared to non-snorers (54.3 + 15.4 years vs 50.7+ 19.5 years) and were more commonly male (OR=1.62(1.52-1.73), p<0.0001)). After controlling for factors such as age, education level, race, income, body-mass index and smoking, the self-reported prevalence of asthma (OR=1.13(1.18-1.48), p<0.0001)), COPD (OR=1.35(1.18-1.55), p<0.0001)), asthma-COPD Overlap Syndrome (OR=1.70(1.24-1.65), p<0.0001)), coronary heart disease and angina (OR 1.24(1.08-1.42), p=0.0021)), arthritis (OR=1.27(1.18-1.37), p<0.0001)) and depression (OR=1.57(1.44-1.71), p<0001)) was higher in respondents who snored as compared to those wo did not snore. Snoring was however, not associated with a higher prevalence of stroke, cancer, kidney disease or diabetes.

CONCLUSIONS: These results demonstrate that snoring is associated with a higher prevalence of common co-morbid medical conditions.

CLINICAL IMPLICATIONS: Given the significantly higher prevalence of snoring as compared to obstructive sleep apnea, future studies should evaluate whether there is a causal relationship between snoring and comorbidities.
