Objective: To investigate the correlation between different anthropometric measures and sleep disorder breathing (SDB) as measured by apnea / hypopnea index (AHI) in obstructive sleep apnea (OSA) patients. Also to find out the most correlated anthropometric measure with SDB. Methods: We evaluated 80 patients with suspected OSA underwent polysomnography and anthropometric measurements including body mass index (BMI), waist–hip ratio (WHR), waist to height ration (WHtR), waist, and hip circumference. Results: A statistically significant correlation was found between the anthropometrics variables (BMI, WHtR, W, and WHR) relative to the AHI (r = 0.516, p< 0.001; r = 0.477, p = 0.002; r = 0.333, p=0.024; and r = 0.302, p=0.042 respectively) in men. These correlations were confirmed by observed significant negative correlation of the mentioned anthropometrics variables and oxygen saturations (SMED, SMIN). No significant correlation was found between anthropometrics and SDB in women. The step-wise linear regression showed that increasing BMI has the most effect on severity of AHI followed by WHR in men (Beta = 0.469, and 0.22 respectively). Conclusion: BMI is the most reliable obesity indicator that significantly correlated with SDB. BMI is more appropriate indicator than WHtR or W to predict SDB.
