Most Asian countries have limited resources for polysomnography. Risk factors Obstructive Sleep Apnea (OSA) in populations may be different from the Western countries. Knowing physical risk OSA may a helpful tool clinicians to select suitable patients tested OSA. We enrolled consecutive OSAsuspected patients between October 1st, 2006 and September 30th, 2007. Physical including Body Mass Index (BMI), Neck Circumference (NC), Waist (WC) were recorded. The correlations of BMI, NC, WC Apnea-Hypopnea Index (AHI) executed. Various cut points BMI, NC, calculated for sensitivity specificity severity During study period, there 66 enrolled. All three parameters (BMI, WC) significantly correlated with AHI. highest correlation index was between BMI AHI (0.604), whereas AHI-WC AHI-NC 0.571 0.440, respectively. Only BMI WC, but not related more than 25 kg/m2 had the highest (93.8%) severe OSA, 101.8 cm (92%). In conclusion, NC are OSA suspected Thai patients. NC, were associated In resource-limited facilities, these parameters to evaluate appropriately.
