A descriptive cross-sectional study of polysomnographic characteristics and clinical significance in Chinese patients with clinically suspected Obstructive Sleep Apnea-Hypopnea Syndrome (OSAHS)

Key Points

This study aims to examine the polysomnographic characteristics and clinical significance of patients suspected of having OSAHS in central China.
Descriptive cross-sectional study design involving 100 patients suspected of OSAHS.
Patients were assessed using polysomnography to evaluate respiratory events and sleep characteristics.
Analysis included correlations between body mass index (BMI), apnea-hypopnea index (AHI), and oxygen levels.
76% of patients had overweight or obesity, with a mean BMI of 27.4 kg/m².
90.9% of respiratory events were classified as obstructive apnea, with 44% suffering from severe OSAHS.
Significant positive correlation (r = 0.316, p = 0.001) between BMI and AHI observed, notably in males.

Abstract

To explore polysomnographic features and clinical implications of suspected OSAHS patients in central China. Of 100 enrolled patients, 81% were males, with a mean age of 41.6 ± 13.5 years. 76% had overweight or obesity and the mean BMI was 27.4 ± 4.9 kg/m², while 44% suffered severe OSAHS. Obstructive apnea occupied 90.9% of respiratory events. BMI positively correlated with AHI (r = 0.316, p = 0.001), with statistical significance only seen in males. AHI presented negative correlations with minimum oxygen saturation and deep sleep proportion. Oxygen level varied distinctly among severity groups. REM-stage minimum SpO₂ had the closest inverse link with AHI, representing a rarely reported regional characteristic.
