Introduction
The relationship between metabolic syndrome and vestibular dysfunction has attracted significant attention; however, consensus regarding their association remains elusive. This study aims to comprehensively evaluate the relationship between metabolic syndrome and vestibular dysfunction through observational analysis of the NHANES database and Mendelian Randomization (MR) analysis.
Methods
Data from the NHANES database spanning 1999 to 2004 were utilized for observational analysis, alongside Mendelian Randomization (MR) methodology. NHANES data analysis was conducted using EmpowerStats 4.1, while MR analysis utilized publicly available Genome-Wide Association Studies (GWAS) data.
Results
Observational analysis of NHANES data revealed an association between metabolic syndrome and vestibular dysfunction in unadjusted models, which disappeared upon adjustment for various confounding factors. MR analysis results indicated no significant causal relationship between metabolic syndrome and vestibular dysfunction; however, low high-density lipoprotein cholesterol levels and hypertension were identified as potential risk factors for vestibular dysfunction.
Conclusion
The findings of this study suggest that there is no apparent association between metabolic syndrome and vestibular dysfunction. However, low high-density lipoprotein cholesterol levels and hypertension may serve as risk factors for vestibular dysfunction. This discovery contributes to the precision prevention and treatment of vestibular dysfunction, thereby enhancing the quality of life for affected individuals.
