# Polysomnographic Analysis in Snoring Patients

## TL;DR

This study analyzed sleep data from snoring patients to identify patterns linked to age, gender, and severity of breathing issues.

## Contribution

The study systematically characterizes snoring patients using PSG parameters across demographic and severity groups.

## Key findings

- Male patients had higher AHI, ODI, and SI values than females under the same BMI.
- Elderly patients showed significantly higher AHI and ODI compared to younger patients.
- ODI had the strongest correlation with BMI at moderate AHI levels.

## Abstract

Objective: This study aimed to investigate differences and correlations in polysomnography (PSG) parameters among snoring patients in the otolaryngology department by gender, age group, and apnea-hypopnea index (AHI) severity level.

Methods: Differences in parameters (AHI, oxygen desaturation index (ODI), snoring index (SI), body mass index (BMI), and age (AGE)) were compared across genders, age groups, and AHI severity levels. Relationships among these parameters were analyzed using bar charts, box plots, and correlation matrices to characterize snoring patients.

Results: Under the same BMI, male patients exhibited significantly higher values for AHI, ODI, and SI compared to female patients (p < 0.01). Both AHI and ODI increased with age, showing significantly higher values in elderly patients (≥60 years) compared to younger patients (<40 years) (p < 0.01). No significant differences in SI were observed across different AHI severity groups. At moderate AHI levels, ODI demonstrated the strongest positive correlation with BMI (r = 0.58) and the strongest negative correlation with SI (r = -0.61). AHI was positively correlated with both ODI and BMI, with the strongest correlations observed at severe AHI levels (r = 0.84, r = 0.49, respectively).

Conclusion: The systematic analysis of these parameters provides a more comprehensive and scientifically grounded reference for early diagnosis, personalized treatment planning, and dynamic assessment of snoring conditions.
