Abstract Background The existing screening tools for the detection of moderate and severe obstructive sleep apnea (OSA) are tailored to Western individuals. The aim of this study was to formulate and validate a simple anthropometric tool for OSA screening in a Japanese male population by incorporating objective indicators obtained during routine medical checkups. Methods In total, 443 Japanese men, who were suspected of having OSA and visited our sleep disorder clinic from 2009 to 2012, were retrospectively divided into two groups (development group [DG], n = 206; validation group [VG], n = 237). In the DG, OSA was defined as an apnea–hypopnea index of ≥ 15 events/h. Data regarding clinical and anthropometric variables (age, body mass index [BMI], neck circumference [NC], waist circumference [WC]) were obtained. For parameters that were associated with OSA on simple logistic regression analysis, cutoff values were calculated with receiver operating characteristic curves to create a new screening tool. The utility of the tool was evaluated in the VG and compared to that of the modified Berlin questionnaire (mBQ) for OSA. Results Age (odds ratio [OR] = 1.033, p = 0.002), BMI (OR = 1.231, p |
