The Association Between Serum Vitamin D Levels and Benign Paroxysmal Positional Vertigo

Abstract

Objective: This study aimed to evaluate the association between serum vitamin D levels and benign paroxysmal positional vertigo (BPPV). Participants and Methods: This prospective study consisted of 137 participants. There were 69 participants in the BPPV group compared with 68 healthy participants. Blood samples from both groups were collected from all participants to assess serum vitamin D levels. Results: No significant difference in demographic data between BPPV and control groups. The results showed that the mean serum vitamin D levels in the BPPV group was lower than that of the control group ( P value = .001). Among BPPV participants, there was no statistically significant difference between mean serum vitamin D levels of participants with recurrent BPPV, and that of newly diagnosed BPPV participants ( P value = .313). Conclusion: A statistically significant association between lower mean serum vitamin D levels in the BPPV group compared with that of the control group. Therefore, low serum vitamin D levels may be one of the risk factors for BPPV.
