青年人族群行動電話使用者非特異性自覺症狀與聽力狀況關聯性研究

近年來行動電話的使用普及率呈倍數成長，直至91年底台灣之行動電話普及率已達到全世界第一。然而行動電話的使用會有無線電波的暴露，其對人體的可能健康效應是值得重視及探討的。我們針對某大學91年入學新生，利用問卷來調查其行動電話使用及自覺症狀發生狀況，在扣除20歲以上及無效問卷後，共有394人進行行動電話使用及自覺症狀發生率關聯研究，結果發現在控制年齡、性別、電腦使用情形等變項下，使用logistic迴歸分析頭痛、難以專心、耳朵溫熱等自覺症狀與行動電話使用量的OR比分別為：1.005 (95%CI 1.001~1.259)、1.006 (95%CI 1.002~1.010)、1.005 (95%CI 1.001~1.008)，而上述之394人通知純音聽力檢查，在剔除經醫師診斷為外耳道異常或耳朵疾病史者(4人) 共有184人納入聽力狀況研究。經複迴歸分析結果在慣用左耳於1kHz及不固定耳於250Hz，觀察到有顯著意義，其迴歸係數各為 -0.038,0.024。由本研究結果顯示，行動電話使用量(累積時數)與頭痛、難以專心、耳朵溫熱等自覺症狀有關聯性，但在缺乏醫師之臨床診斷做證下，如此之結果仍有更近一步研究探討之必要。而聽力損失雖未觀察到具臨床上意義之關聯性，由於所選擇對象之暴露期間較短，仍須作長期之世代追蹤觀察其變化情形。

The recent years, the popularity rate of mobile phone has increased by multiple. The popularity ratio of mobile phone in Taiwan achieved the first place all over the world till the end of 2002. It is an important issue that should be paid attention to and discussed that people are exposed to the mobile phone radio frequency radiation, which has an influence on health effects. Our study population is the freshman in a certain university, 2002. We used a structure questionnaire as investigating tool to investigate the relationship of subjective symptoms, hearing ability and using mobile phone among young adults. After excluding the invalid survey sheets and those students over 20 years old, 394 students are left to be involved in this experiment. And we find that with age and gender controlled, using multiple logistic regression to analyze symptoms of “Headache”, “Difficulty concentration” and “Warmth on ear” with RF exposure and estimate the OR ratio are as following: 1.005(95%CI 1.001~1.259), 1.006(95%CI 1.002~1.010), 1.005(95%CI 1.001~1.008). Among the 394 students mentioned above informed to be carried out the pure-tone audiometry, 184 students are left to be involved in the hearing experiment after doctor excluded 4students and having the ear disease history. By multiple regression analyze, we find it significant under the accustomed left ear is on 1KHz and unaccustomed ear is on 250Hz of right ear and βestimate are —0.038 and 0.024. The result of the research shows that the hour of using mobile phone is relative with subjective symptoms of headache, difficultly concentrating, warmth on ear and so on. However, without clinical diagnosis, further study to the result is necessary. We don’t observe hearing loss with clinical correlation. It may be the reason of short exposure of the members who choose so we have to keep observing the variation for generations.
