Abstract

BACKGROUND

Cellphone and cordless phone use is very prevalent among early adolescents, but the extent and types of use is not well documented. This paper explores how, and to what extent, New Zealand adolescents are typically using and exposed to active cellphones and cordless phones, and considers implications of this in relation to brain tumour risk, with reference to current research findings.

METHODS

This cross-sectional study recruited 373 Year 7 and 8 school students with a mean age of 12.3 years (range 10.3-13.7 years) from the Wellington region of New Zealand. Participants completed a questionnaire and measured their normal body-to-phone texting distances. Main exposure-metrics included self-reported time spent with an active cellphone close to the body, estimated time and number of calls on both phone types, estimated and actual extent of SMS text-messaging, cellphone functions used and people texted. Statistical analyses used Pearson Chi2 tests and Pearson's correlation coefficient (r). Analyses were undertaken using SPSS version 19.0.

RESULTS

Both cellphones and cordless phones were used by approximately 90% of students. A third of participants had already used a cordless phone for ≥ 7 years. In 4 years from the survey to mid-2013, the cordless phone use of 6% of participants would equal that of the highest Interphone decile (≥ 1640 hours), at the surveyed rate of use. High cellphone use was related to cellphone location at night, being woken regularly, and being tired at school. More than a third of parents thought cellphones carried a moderate-to-high health risk for their child.

CONCLUSIONS

While cellphones were very popular for entertainment and social interaction via texting, cordless phones were most popular for calls. If their use continued at the reported rate, many would be at increased risk of specific brain tumours by their mid-teens, based on findings of the Interphone and Hardell-group studies.

摘要

背景

手机和无绳电话在青少年中非常普遍,但使用的程度和类型并没有得到很好的记录。本文探讨了新西兰青少年通常如何使用和接触活动手机和无绳电话,以及考虑到这对脑瘤风险的影响,参考了当前的研究结果。

方法

这项横断面研究从新西兰惠灵顿地区招募了 373 名 7 年级和 8 年级的学生,平均年龄为 12.3 岁(范围为 10.3-13.7 岁)。参与者完成了一份问卷,并测量了他们正常的身体与手机短信的距离。主要的暴露度量包括自我报告的时间花在靠近身体的活动手机上,估计两种手机的通话时间和次数,估计和实际的短信数量,使用的手机功能和发短信的人。统计分析使用了 Pearson Chi2 检验和 Pearson 相关系数(r)。使用 SPSS 版本 19.0 进行分析。

结果

大约 90%的学生都使用手机和无绳电话。三分之一的参与者已经使用无绳电话≥7 年。在调查到 2013 年中期的 4 年内,6%的参与者的无绳电话使用量将等于 Interphone 最高十位数(≥1640 小时),以调查的使用速度。手机使用量高与手机夜间位置、经常被唤醒和在学校感到疲倦有关。超过三分之一的家长认为手机对孩子的健康有中度到高度的风险。

结论

虽然手机非常受欢迎,用于娱乐和短信社交互动,但无绳电话最受欢迎的是通话。如果按照报告的速度继续使用,那么根据 Interphone 和 Hardell 小组的研究结果,许多人在青少年中期会有更高的特定脑瘤风险。
