evaluation of the association between serum levels of vitamin d, calcium and phosphorus with benign paroxysmal positional vertigo

Background :benign paroxysmal positional vertigo (bppv) is the most common cause of periodic vertigo in patients, characterized by short-term attacks that are exacerbated by changes in head position. deficiency or imbalance in serum levels of calcium, phosphorus, and vitamin d may compromise the health of inner ear structures and neuromuscular functions related to balance. objectives :the present study aimed to investigate the association between serum levels of vitamin d, calcium, and phosphorus and bppv. methods :a case-control study was conducted, using a census method, on 56 patients with bppv who referred to the ent clinic of imam khomeini hospital, kermanshah, iran during 2019 - 2020. subjects were randomly divided into two groups: case and control. the measurement tool was a researcher-made checklist. the dys-hallpike maneuver was used to diagnose vertigo, and high-performance liquid chromatography (hplc), colorimetric assays, and aas were used to measure serum phosphorus, calcium, and vitamin d levels. statistical analysis was performed with spss version 25. results :fifty-six people were examined. twenty-eight of these people were in the case group and 28 were in the control group, whose average age was 44.1 ± 15.8 years and 44.2 ± 15.7 years, respectively. serum vitamin d levels were significantly lower in the case group (27.55 ± 15.36) compared to the control group (39.63 ± 15.83, p = 0.005). no significant differences were observed in serum phosphorus or calcium levels between the groups (p > 0.005). conclusions :vitamin d deficiency exacerbates bppv, especially in women during menopause. health care providers should prioritize programs to improve vitamin d levels, especially in high-risk groups.
