最近，日本雪松花粉症的病例有所增加，特别是在儿童中。对栃木县三武町的在校儿童、初中生和高中生进行了问卷调查，进行了内窥镜检查，并采集了鼻分泌物和血液样本。关于致敏过程和日本雪松花粉症的发病，发现了以下结果：根据问卷调查，日本雪松花粉症阳性的百分比在6岁的儿童中约为10%，在17岁的儿童中约为25%。然而，根据血液样本，日本雪松花粉抗体在7岁时突然增加。我们发现了年龄风险因素。日本雪松花粉症的敏感性出现在7岁，花粉症的症状发展在8岁。比较了学生血液中日本杉花粉抗体阳性率和粉尘螨抗体阳性率。有Der f抗体的儿童比没有Der f抗体的儿童表现出更高的日本雪松花粉抗体阳性率。对日本雪松花粉的致敏作用依赖于Der f。我们关注居住环境。城市儿童中日本雪松花粉抗体的阳性率高于农村儿童。症状发作的百分比是在公寓楼高于独立的房子。总之，对日本雪松花粉的致敏主要发生在6 - 7岁，受住宅类型（公寓或房屋）（特别是Der f）的影响，并且其发病受城市或农村的影响。
Recently, increases in cases of Japanese cedar pollinosis have been found, especially in children. School children, junior high school students and high-school students in Mibu-machi, Tochigi prefecture were given questionnaires, rhinoscopic examinations were done and nasal secretions and blood samples were taken. The following results for the process of sensitization and the onset of Japanese cedar pollinosis were found. According to the questionnaire, the percentage of positive Japanese cedar pollinosis was about 10% in 6-year-olds and about 25% in 17-year-olds. However, according to the blood samples, Japanese cedar pollen antibodies abruptly increased in 7-year-olds. We found age risk factors. Sensitization to Japanese cedar pollinosis appeared in 7-year-old, with symptoms of pollinosis developing in 8-year-olds. We compared the percentage of positive rate of antibodies of Japanese cedar pollen with percentage of Dermatophagoides farinae (Der f) from the student's blood samples. Children having Der f antibodies showing higher positive rate of Japanese cedar pollen antibodies than children who do not have Der f antibodies. Sensitization to Japanese cedar pollen is dependent on Der f. We paid attention to resident environments. Children having Japanese cedar pollen antibodies were higher in children living in the urban than in rural. The percentage of onset of symptoms was higher in apartment buildings than in detached houses. In conclusion, sensitization to Japanese cedar pollen occurs mostly at age 6 - 7, is influenced by type of dwelling (apartment or house), (specially by Der f) and it's onset is affected by urban or rural.
