OBJECTIVE: Several studies have reported the association of benign paroxysmal positional vertigo (BPPV) with vitamin D deficiency. This study aimed to evaluate serum 25-hydroxy vitamin D (25 (OH) D) levels in native Chinese postmenopausal women with de novo idiopathic BPPV and to investigate the possible relationship between the occurrence of BPPV and low 25 (OH) D levels. METHODS: This retrospective study comprised of 85 postmenopausal women with de novo idiopathic BPPV and 80 age-matched healthy controls. All subjects had bone mineral density (BMD) and serum 25 (OH) D levels measurements recorded, and the results were compared. RESULTS: The prevalence of reduced BMD (T score <-1.0) was significantly higher in female patients with BPPV than in healthy controls (71.8% vs. 51.2%, p = .004). The mean serum 25 (OH) D levels were also significantly lower in female patients with BPPV than in healthy controls (19.1 ± 5.2 vs. 22.5 ± 5.8, p < .001). The regression analyses demonstrated that vitamin D deficiency was associated with BPPV with an odds ratio of 2.1 (95% confidence interval = 1.1-3.1, p = .031). CONCLUSION: Our study suggests that low 25 (OH) D may be a risk factor for BPPV in postmenopausal women.
