[An epidemiologic study of sleep-disordered breathing in the male population of Lorraine: preliminary results].
The prevalence of sleep-disordered breathing (SDB) was evaluated in a male population sample of Lorraine (university staff), with a protocol including a self-completed standardized questionnaire, anthropometry (including neck, waist and hip circumferences) and non-invasive ear, nose, and throat examination. Among 357 subjects present in the institution at the moment of the survey, 334 (93.6%) accepted to participate, and 300 (84%) returned the questionnaires. The anthropometric results corresponded to the French normative values according to gender and age. We chose a value of 32 as limit of the body mass index (BMI) between weight excess and obesity; this limit was exceeded by 7.2% of the subjects. The mean age of the sample was 44.8 (SD 10.1) years; the waist-to-hip ratio was of 0.907 +/- 0.053. The ENT examination found a high prevalence of nasal septum deviations (52.6%), of soft palate (25.2%), and uvula (42%) abnormalities; 32.1% of the subjects had experienced amygdalectomy. The non-responses to the questionnaire were infrequent (less than 2%), except for the questions regarding a history of hypertension (2.6%), weight fluctuations the last 5 years (7.6%), and the number of years in school (12%). The questionnaire included, for each question, the optional answer "don't know"; this answer was chosen for the questions concerning the duration of snoring (37.1%), stopping breathing during sleep (12.7%) and the parental history of narcolepsy (18.7 and 20.7%) and sleep apnoea (33.7 and 36.4%). 5.7% of the subjects declared sleep apnoeas at least once per week: 16.1% had unrefreshing sleep; 10.6% admitted to excessive daytime sleepiness; 41.9% were habitual snorers. These results indicate a prevalence of SDB in our sample which is comparable to the figures obtained in other European studies. Further analysis of our data will indicate if, besides weight excess and its troncular distribution, cigarette smoking and respiratory symptoms, the "minor" ENT abnormalities play a role in the pathogenesis of SDB.
