The purpose of this study was to clarify ownership and usage of mobile phones among young patients with brain tumors in Japan. The subjects of this study were patients with brain tumors diagnosed between 2006 and 2010 who were between the ages of 6 and 18 years. The target population for the analysis was 82 patients. Patients were divided into two groups: 16 patients who were mobile phone owners 1 year before diagnosis, and 66 patients who did not own mobile phones (non-owners). Using data on the mobile phone ownership rate obtained from three general-population surveys, we calculated the expected number of mobile phone owners. The three age-adjusted standardized ownership ratios were 0.83 (95% confidence interval [CI]: 0.56-1.22), 0.51 (95% CI: 0.24-1.04), and 0.75 (95% CI: 0.42-1.32). The mobile phone ownership prevalence among the young Japanese patients with brain tumors in the current study does not differ from available estimates for the general population of corresponding age. However, since the use of mobile phones among children is increasing annually, investigations into the health effects of mobile phone use among children should continue.

本研究的目的是阐明日本年轻脑肿瘤患者手机的拥有情况和使用情况。本研究的对象是2006年至2010年间确诊的6至18岁脑肿瘤患者。分析的目标人群为82名患者。患者分为两组：16名在诊断前1年拥有手机的患者，以及66名未拥有手机的患者（非拥有者）。利用从三项一般人群调查中获得的手机拥有率数据，我们计算了手机拥有者的预期数量。三个年龄调整后的标准化拥有率分别为0.83（95%置信区间[CI]：0.56 - 1.22）、0.51（95%CI：0.24 - 1.04）和0.75（95%CI：0.42 - 1.32）。本研究中日本年轻脑肿瘤患者的手机拥有率与相应年龄一般人群的现有估计值没有差异。然而，由于儿童中手机的使用每年都在增加，对儿童使用手机的健康影响的调查应该继续。《生物电磁学》。38:349 - 355，2017年。©2017威利期刊公司。
