Correlation Between Self-factors and Seasonal Factors in Adult Patients with Recurrent BPPV
Objective To analyze the relationship between self-factors and seasonal factors in adult patients with recurrent benign paroxysmal positional vertigo(BPPV),and explore the related factors of recurrent BPPV.Methods A total of 815 adult patients with re-current BPPV admitted to Beijing Puren Hospital from February 2015 to January 2022 were included in a retrospective cohort study.The age,gender,and seasonality of onset were analyzed,and the effects of vascular risk factors,calcium and vitamin D supplementation were explored.Results Patients with recurrent BPPV ranged in age from 22 to 88 years,with a median age of 61(55,67)years,and the gender ratio of males to females was 1∶3.01.There were no significant differences in age,age composition and prevalence of vascular risk factors between males and females(P＞0.05).The proportion of calcium and vitamin D supplementation in female patients was higher than that in male patients(P＜0.001).The occurrence of recurrent BPPV had no significant seasonal regularity,but showed an increas-ing trend in cold season.Vascular risk factors were correlated with age,but not with gender or season.The patients with multiple recur-rence of BPPV accounted for 20.86％(170/815),calcium and vitamin D supplementation were independent influencing factors.Conclusion Recurrent BPPV occurs frequently in females,and is more common in old age,and is more frequent in cold season.Calci-um and vitamin D supplementation may reduce the recurrence frequency.
