Body surface area: a new anthropometric measurement for obstructive sleep apnea syndrome

We aimed to explore the possibility of using body surface area (BSA) as a new anthropometric measurement in evaluation of OSAS. Obesity was defined as having a BMI ≥ 30 kg/m2. BSA were calculated using the Mosteller and Boyd formulas. Totaly 426 (306 male) cases were included in this study. The mean BMI was 33.0 kg/m . The mean BSA was 2.06 m and 2.11 m respectively. BMI, AHI, oxygen desaturation, ODI and oxygen saturation were found different between the groups. Both BMI and BSA correlated positively with AHI, oxygen desaturation and ODI and negatively with oxygen saturation. There was no difference between BMI and BSA in mild cases in both gender. However, in moderate and severe cases, BMI and BSA were higher in males. We dedected that BSA and BMI display similar sensitivity and specificity values for the prediction of severe OSAS. To the best of our knowledge, this is the first study to examine the potential association between BSA and the severity of OSAS. As a result, we determined that BSA correlated with polisomnographic parameters as BMI. In severe OSAS BSA can be used as a predictor parameter like BMI.
