Objective: The primary objective of this research was to conduct polysomnography tests on individuals diagnosed with Obstructive Sleep Apnea-Hypopnea Syndrome (OSAHS) in the Qingpu suburb of Shanghai, China. The study entailed the examination of diverse sleep monitoring parameters linked to age, gender, and disease severity to thoroughly investigate snoring patterns among residents of the Qingpu District. The resulting research outcomes are intended to offer significant insights for formulating successful clinical treatment plans and strategies. Methods: Polysomnography was conducted on 90 snoring patients, and parameters including Apnea-Hypopnea Index (AHI), Oxygen Desaturation Index (ODI), Snoring Index (SI), AGE, GENDER, and Body Mass Index (BMI) were statistically evaluated. Results: Average values of AHI, ODI, SI, and BMI across different age groups were relatively high without significant variations. When examining gender differences, it was found that both men and women exhibited higher average Apnea-Hypopnea Index (AHI) and Oxygen Desaturation Index (ODI), while notable discrepancies were not observed in Snore Index (SI), age, or Body Mass Index (BMI) between men and women.When stratified by the severity of OSAHS, box plots for AHI and ODI revealed a progressive rise in average values as OSAHS severity increased, culminating at severe stages. The correlation analyses indicated a robust positive relationship between AHI and ODI, with correlation coefficients r values of 0.30, 0.55, 0.77, and 0.84 for normal, mild, moderate, and severe OSAHS categories, respectively. Conclusion: Age did not significantly impact the mean values of AHI, ODI, SI, and BMI in residents of Qingpu, Shanghai. No substantial gender disparities were observed concerning snoring index, age of onset, and BMI. However, men exhibited a higher propensity for apnea and hypoxia compared to women, particularly in terms of AHI and ODI. The study highlighted a robust association between AHI and ODI, with the strength of this association increasing with OSAHS severity levels.
