In order to examine the relationship between sleep disordered breathing (SDB) and lifestyle-related illness, 207 men who were randomly selected from 824 men admitted to Shinonoi hospital for health screening were subjected to short-form polysomnography for one night. Fifty-nine men showed moderate to severe SDB of more than 15 events of apnea and hypopnea per hour (AHI), and had a significantly higher prevalence of hypertension, glucose intolerance, liver dysfunction, hypercholesteremia, and showed significant increases in blood pressure and HbA1c compared with men without SDB (AHI<5 events/hour). Also, when the obese men were excluded from the analysis, the prevalence of hypertension was still higher in the moderate to severe SDB group than in the group without SDB. These findings suggest that there is a close association in men between SDB and lifestyle-related illness such as hypertension, hyperlipidemia, glucose intolerance, and liver dysfunction.
