Australian adolescents are increasingly using mobile telephones (MP) while the debate on MP safety persists. This group is not generally engaged in full-time employment, suggesting that their MP use is not work related. We investigated possible predictors of MP use in young people.
We assessed exposure to radiofrequency energy from MP by means of a self-administered questionnaire adapted from INTERPHONE--an international case-control study of adult brain, head and neck tumours. We investigated possible determinants of MP use in adolescent Australians using self-reported number of incoming and outgoing voice calls as exposure metric.
There is a high prevalence of MP use amongst Australian adolescents (94%). Males were significantly younger than females at age of first uptake of MP (P= 0.02). Participants without siblings were significantly younger at age of first uptake. Personality traits were associated with regular MP usage: higher psychoticism scores were associated with regular use (IRR = 1.06, P= 0.03); there was a tendency for students with higher extraversion scores to report more MP use. Parental socio-economic status was associated with MP use, but parents who expressed moderate/high level concerns about possible health risks of use were more likely to have children who used MP (OR = 4.06, P= 0.05).
Almost all adolescent Australians use MP, but regular exposure was associated with personality traits. Parental socio-economic status and perceived health risks of MP use were also associated with use of phones. Longitudinal studies are needed to assess the predictors of mobile phone use in the long term.
在关于移动电话安全性的争论持续存在的情况下，澳大利亚青少年使用移动电话（MP）的情况日益增多。这一群体通常并非全职工作，这表明他们使用移动电话与工作无关。我们调查了年轻人使用移动电话的可能预测因素。
我们通过一份根据国际成人脑、头颈部肿瘤病例对照研究“INTERPHONE”改编的自填式问卷，评估了移动电话射频能量暴露情况。我们以自我报告的来电和去电语音通话次数作为暴露指标，调查了澳大利亚青少年使用移动电话的可能决定因素。
澳大利亚青少年中移动电话使用率很高（94%）。首次使用移动电话时，男性的年龄显著低于女性（P = 0.02）。没有兄弟姐妹的参与者首次使用移动电话时的年龄显著更小。人格特质与经常使用移动电话有关：精神质得分较高与经常使用有关（发病率比值比=1.06，P = 0.03）；外向性得分较高的学生有报告更多移动电话使用量的趋势。父母的社会经济地位与移动电话使用有关，但对使用可能的健康风险表示中度/高度担忧的父母，其子女更有可能使用移动电话（比值比=4.06，P = 0.05）。
几乎所有澳大利亚青少年都使用移动电话，但经常暴露与人格特质有关。父母的社会经济地位以及对移动电话使用的感知健康风险也与电话使用有关。需要进行纵向研究以长期评估移动电话使用的预测因素。
