Increased incidence of alcohol use disorder and alcohol-related psychiatric disorders in patients with obstructive sleep apnea: A nationwide population-based cohort study

Abstract

BackgroundObstructive sleep apnea (OSA) and alcohol-related diseases (ARDs), including alcohol use disorder, alcohol-related psychiatric disorders, alcoholic liver disease, alcoholic polyneuropathy alcoholic cardiomyopathy, and alcoholic gastritis, are both highly prevalent conditions. Alcohol consumption is associated with a higher risk of sleep apnea. However, whether OSA increases the risk of ARD has not, as yet, been studied comprehensively. Our study aimed to determine whether OSA increases the subsequent risk of ARD. MethodsThis study utilized the data from Taiwan's National Health Insurance Database between 2000 and 2015. We identified 7722 individuals newly diagnosed with OSA and randomly selected sex-, age-, and index date-matched (1:3) 22,166 controls without OSA, with a total of 29,888 subjects. We used the Fine and Gray's survival analysis to estimate the effects of OSA on ARD. ResultsThe OSA cohort had an adjusted hazard ratio of subsequent ARDs as 1.486 (95% Confidence Interval: 1.301–1.698), when comparing the cohort without OSA. The Kaplan-Meier analysis showed that the cumulative incidence of ARDs was significantly higher in the OSA cohort than in the controls in the first year of follow-up, till the end of the follow-up. A post-hoc analysis showed that OSA was associated with alcohol use disorder, alcohol-related psychiatric disorders, and alcoholic liver disease, but not alcoholic polyneuropathy, alcoholic cardiomyopathy, and alcoholic gastritis. The use of psychoactive medication, including the sedative-hypnotics, antidepressants or antipsychotics were associated with a lower risk of ARDs. ConclusionsOur study demonstrates that the OSA patients are at a higher risk of developing ARDs.
