Prevalence of sleep disordered breathing and sleep apnea in 50- to 70-year-old individuals. A survey (see comments)

摘要

PURPOSE: To determine the prevalence of sleep disordered breathing (SDB) and sleep apnea syndrome (SAS) in a general population aged from 50 to 70 years. SUBJECTS AND METHODS: We recruited 76 individuals aged between 50 and 70 years, chosen at random from the electoral census. They were invited to the clinic where a detailed medical history was taken and physical examination, ENT examination, pulmonary function tests and night time recording of respiratory variables performed. RESULTS: The prevalence of SDB (apnea-hypopnea index >/= 5) was 28.9%, and there were no differences between men (28%) and women (30%). However, the prevalence of SAS was 6.8%, and there were differences between men (5 cases) and women (0 cases) (p = 0.0521). Subjects in the SDB group had higher systolic blood pressure than in the non-SDB group (p < 0.05). CONCLUSIONS: SDB and SAS are common among 50- to 70-year olds. The prevalence of SDB was 28.9% and the prevalence of SAS was 6.8%.
