title: Association between osteoporosis and benign paroxysmal positional vertigo: a systematic review.
abstract: BACKGROUND
  Increasing recent evidence has implicated osteoporosis as a risk factor for benign paroxysmal positional vertigo (BPPV). We conducted a systematic review to examine the association between osteoporosis and BPPV.
  
  
  METHODS
  Four electronic databases (PubMed, EMBASE, Cochrane Library, and the China Network Knowledge Infrastructure) were searched to identify all papers, published in either English or Chinese, examining the association between osteoporosis (osteopenia) and BPPV.
  
  
  RESULTS
  Seven studies were eligible for analysis, though these studies included some weaknesses. Most of the studies demonstrated a correlation between osteoporosis (osteopenia) and the occurrence and recurrence of BPPV, especially in older women. Patients with osteoporosis may require more canalith-repositioning procedures.
  
  
  CONCLUSIONS
  This systematic review provides insight into currently available evidence and elucidates the possible existence of an association between BPPV and osteoporosis (osteopenia). However, the evidence supporting that conclusion is not strong, and further studies are needed to clarify the association between these conditions.
