Abstract

The aim of the work: to study the correlation between body mass index and apnoea-hypopnoea index in obese patients in the preoperative period of bariatric surgery.

Materials and Methods. Clinical monitoring was performed on 50 obese patients undergoing preoperative preparation for bariatric surgery. The patients' ages ranged from 24 to 65 years (mean (43.2±9.7) years), and their BMI ranged from 35.0 to 60.8 kg/m² (mean (44.0±5.6) kg/m²). The degree of daytime sleepiness was assessed using the Epworth Sleepiness Scale (ESS), and the risk of obstructive sleep apnea-hypopnea syndrome (OSAHS) was assessed using the STOP-Bang scale. Polysomnography was performed to determine the apnoea-hypopnoea index (AHI). Statistical analysis was performed using Statictica 10.0 software.

Results. The study revealed a statistically significant positive correlation between BMI and AHI (r=0.53; p<0.001; a=0.05). A comparison by gender revealed that, as in men, the correlation between BMI and AHI is moderately positive in women, but it is more statistically significant in men (r=0.54; p<0.001; a=0.05) than in women (r=0.50; p<0.001; a=0.05). There was also a tendency for the risk of OSAHS to increase with age (r=0.55; p<0.001; a=0.05).

Conclusions. The severity of obstructive sleep apnea-hypopnea syndrome increases with rising body mass index. OSAHS screening should be a mandatory step in the preoperative preparation of obese patients before bariatric surgery.
