Objective
To investigate the possible correlation between benign paroxysmal
positional vertigo (BPPV), seasonality, and climatic variations as
indicators of vitamin D deficiency, since otoconia are calcium carbonate
crystals.
Methods
This is a study of patients who received the diagnosis of BPPV from
September 2015 to August 2019. Gender, age, and month of diagnosis were
factors recorded and analyzed. The cut-off age of 50 years is used to
include osteoporotic patients and postmenopausal women. Meteorological
and climatic data of latitude, temperature, sunshine hours, humidity,
precipitation, wind force, atmospheric pressure, and horizontal solar
irradiance were collected.
Results
Four hundred and eighty-five patients were included in the study; 206
were male (42%) and 279 were female (58%). The mean age was 57.8 +/-
15.4 and 54.9 +/- 13.9, respectively; 192 patients were <= 50 years old
(121 female and 71 male) and 293 patients were over 50 years old (135
male and 158 female). A statistical significance in seasonal variation
during autumn months was demonstrated (p-value=5.2 e-05, z-statistic:
9.8164). There was no statistical correlation between the median number
of BPPV patients and the median sunshine hours per month, horizontal
solar irradiance, or other climatic variables.
Conclusions
Our study demonstrates seasonality in BPPV patients in Greece but no
correlation between BPPV and climatic variations as a proxy for
Vitamin-D levels was documented.
