Reduction of bone mineral density in native Chinese female idiopathic benign paroxysmal positional vertigo patients
Abstract
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.
How strong is the evidence?
Evidence Hub reads this as a case-control, done in people. Its evidence level is 4 of 5 (Low · observational). Observational designs can show an association but not prove cause.
