Reduction of bone mineral density in native Chinese female idiopathic benign paroxysmal positional vertigo patients

Objective

This study aimed to investigate the clinical association between idiopathic benign paroxysmal positional vertigo (BPPV) and reduction of bone mineral density (BMD).

Methods

BMD was measured in 78 native Chinese female de novo idiopathic BPPV patients and 126 healthy controls using dual-energy X-ray absorptiometry. We compared the mean T-scores and abnormal BMD prevalence between the two groups.

Results

The mean T-scores were significantly lower in idiopathic BPPV patients than in healthy controls. The prevalence of osteopenia and osteoporosis were significantly higher in idiopathic BPPV patients than in healthy controls (65.4% vs 48.4%, p = 0.013).

Conclusion

BMD reduction may be associated with idiopathic BPPV occurrence.
