Abstract: Objective To analyze the central obesity male patients waistline and waist-hip ratio and with a serious degree of correlation through the measurement of central obesity in patients with obstructive sleep apnea hypopnea syndrom (obstructive sleep apnea - hypopnea syndrome, OSAHS) male patients waist, hip circumference, calculate waist-hip ratio, and the determination of the patients with AHI and minimum blood oxygen saturation level. Methods The waist circumference and hip circumference were measured, waist-hip ratio was calculated, and the patients sleep monitoring process AHI and minimum blood oxygen saturation level in patients with OSAHS waistline and waist-hip ratio and sleep apnea monitoring the linear correlation analysis indicators were conducted. Results Central obesity of OSAHS in the male patients waist circumference and waist-hip ratio and the lowest blood oxygen saturation was negatively correlated with AHI and were positively correlated with AHI (P<0.05). Conclusion Central obesity of OSAHS in the male patients waist circumference and waist-hip ratio can reflect the severity of the illness of the reaction.

Key words: obstructive sleep apnea, central obesity, waist circumference, waist hip ratio, AHI
