We statistically examined the effect of background conditions and coexisting conditions on sleep apnea syndrome (SAS) patients. Thirty-three patients who had been examined using polysomnography (PSG) from April 1, 2019 to December 31, 2020 in Osaka Dental University Hospital were recruited for this study. They were divided into two groups, the severe group (apnea hypopnea index (AHI) over 25) and mild to moderate group (AHI between 5 and 25). The effect of SAS severity on background conditions such as age, gender and obesity, and the prevalence of coexisting conditions, including hypertension, diabetes mellitus (DM), metabolic syndrome (MS) and chronic kidney disease (CKD), were examined with the χ2 test, Student's t-test and multivariate analysis (p<0.05). SAS severity related to age, gender, obesity and hypertension, but not to MS, DM or CKD. Because MS, DM and CKD are closely related to visceral fat, the SAS severity might be related to systemic obesity rather than visceral obesity. (J Osaka Dent Univ 2023; 57: 321-323)
