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.
