According to the 2008 survey conducted by Baba et al., the average prevalence of Japanese cedar-pollen allergy is 26.5% in Japan, although there are great regional differences in the prevalence of this disease. In this study, we investigated the causes of its regional differences.
Regional differences in the 2008 prevalence of cedar-pollen allergy in 47 prefectures, obtained by Baba et al., were examined in terms of the correlations with the following factors: mean cedar pollen count in each region, the pollen dispersal period, relative humidity in February and March, and the concentrations of SPM, NOx and Ox. The pollen counts of cedar and cypress and the sum of these pollen counts were also measured.
The prevalence of cedar-pollen allergy had the highest correlation with the pollen dispersal period, followed by the correlation with the pollen count and relative humidity in the order. There was no statistically significant correlation between the prevalence of cedar-pollen allergy and air pollutants such as SPM.
根据巴巴等人2008年进行的调查，日本雪松花粉过敏的平均患病率在日本为26.5%，尽管该病的患病率存在很大的地区差异。在本研究中，我们调查了其地区差异的原因。
根据巴巴等人的数据，研究了日本47个都道府县2008年雪松花粉过敏患病率的地区差异与以下因素的相关性：各地区雪松花粉平均计数、花粉传播期、2月和3月的相对湿度以及悬浮颗粒物、氮氧化物和氧化剂的浓度。还测量了雪松和柏树的花粉计数以及这些花粉计数的总和。
雪松花粉过敏的患病率与花粉传播期的相关性最高，其次依次是与花粉计数和相对湿度的相关性。雪松花粉过敏的患病率与悬浮颗粒物等空气污染物之间没有统计学上的显著相关性。
