— An epidemiological survey of the prevalence of snoring and sleep apnoeas was performed on 3479 30‐69‐year‐old men living in Bologna, north‐east Italy. First a postal questionnaire was sent. It was returned with appropriate answers by 1170. A 20% random sample of those who did not answer were invited by telephone to return the questionnaire. Among these groups 119 (10%) and 19 (5.6%) respectively answered that they always snored. A random sample of 40 every‐night snorers were studied by polysomnography. Based on the frequency of every‐night snoring and the results of polysomnography we estimated that the minimal prevalence of sleep apnoea among 30‐69‐year‐old men was 2.7% considering an apnoea + hypopnoea index of 10 or more pathological. According to the Lugaresi classification we had a 2.5% prevalence of heavy snorers’ disease (HSD) Stage 1 or higher. These figures indicate that obstructive sleep apnoea during sleep is a major public health problem.
