The correlation between age,body mass index and obstructive sleep apnea hypopnea syndrome

Objective To investigate the correlation between age,body mass index (BMI) and obstructive sleep apnea hypopnea syndrome (OSAHS). Methods To evaluate the difference of age and BMI from various patients then analyze the correlation between age,BMI and the severity of OSAHS according to the data from 526 cases of OSAHS diagnosed by polysomnography(PSG). Results The incidence of OSAHS are high in patients of age from 30 to 70 and high in patients with BMI from 23.0 to 30.0 or above 30.0. It is negative correlation between age and apnea-hypopnea index (AHI),it is positive correlation between BMI and AHI. The absolute value of standardized partial regression coefficient of BMI is larger than that of age. Conclusions It is linear correlation between age,BMI and AHI. The more increased of BMI,the more severe of the state of OSAHS,but the more increased of age,the less severe of the state of OSAHS. The effect of weighton OSAHS is more obvious than that of age.
