An Investigation of Weather Factors Effect on Bell’s Palsy by Comparison With 2 Capital Cities in China

Aim:To evaluate the temperature change (one of the key weather factors) is relevant to Bell’s palsy (BP) occurrence and what kind of role does temperature change play in causing BP, via BP occurrence comparison of 2 capital cities. Materials and Methods:The epidemiological study of BP was conducted between the capital city of Liaoning Province, Shenyang (population: about 7.5 million in 2007 and 2008, climate type: temperate continental monsoon climate) and the capital city of Shanxi Province, Xi’an (population: about 6.5million in 2007 and 2008, climate type: warm sub-humid continental monsoon climate) in Table 1. Result:There were statistically significantly different in BP’s incidence rate between 2 kinds of jobs in 2 different capital cities (P<0.05), in BP’s incidence rate among 4 different seasons even in 2 different capital cities (P<0.05), in BP’s disease extent in 2different capital cities (P<0.05), in disease inducement between 2 different capital cities (P<0.05), and between 4 kinds of BP’s prognosis in 2 different capital cities (P<0.05). Conclusions:There was statistically significant correlation between weather change/character and the actual incidence of BP. The real factors that triggered the incidence of BP should be invested in further study.
