CDC investigators have found that major depression appears to be associated with snorting or stopping breathing during sleep in a national sample of American adults. Men and women with sleep apnea also had higher risks for probable major depression in the study. Snorting or stopping breathing five or more nights a week was strongly associated with probably major depression in men (odds ratio, 3.1) when compared with never snorting or stopping breathing. More research is needed to establish if regular screening for these conditions should be recommended.
