手机使用方式与时长对“手机病”发病的影响

Effect of Cellphone Use Habits and Duration on the Incidence of "Cellphone Disease"

目的 探讨手机使用时长及使用方式（如单手持、双手持、单指操作、多指操作等）与“手机病”（以狭窄性腱鞘炎为主要手部损伤的一类疾病）相关症状发生率的关系。方法 采用随机抽样的方法,在网络平台（问卷之星网络调查平台）与合肥社区居民之中发放、回收问卷,同时随机抽取安徽医科大学在校大学生30人（男女各半）进行“手机使用方式和时长对手部的影响”现场实验。结果48%的调查对象每日使用手机时长为4~8h;92%的调查对象主要使用手机中的聊天工具;84%的调查对象习惯单手使用手机;长时间使用手机后,38%的调查对象出现手指僵硬肿胀、腕部红肿、指关节结节症状。连续使用手机时长小于2h,实验对象均无手部不适症状,当时长达4~6h时,约10.0%的实验对象产生手部不适症状,达8~10h时,16.7%的实验对象产生手部不适症状;玩游戏与使用聊天工具的实验对象出现手部不适症状的比例最高,达13.3%,而看视频则不易出现手部不适症状。结论 手机使用时间越长,实验对象出现“手机病”的概率也越高,同时双手持手机及多指操作较其他手机使用方式更易引起“手机病”。手机使用人群应养成良好的使用习惯,避免长时间使用手机,且在使用过程中,应保持正确的姿势并适当休息,以降低患“手机病”的概率。

Objective To explore the effect of cellphone use duration and habits （e.g. one-hand holding, two- hand holding, one-finger operating, or multi-finger operating） on the incidence of ＂cellphone disease＂ （typical- ly characterized by stenosing tenosynovitis）. Methods By random sampling, a questionnaire survey was conducted on an online platform （Sojump Online Questionnaire Platform） and also in community residents of Hefei. Meanwhile, 30 students randomly selected from Anhui Medical University （15 males, and 15 females） participated in a field experiment of ＂effect of eellphone use duration and habits on hands＂. Results 48% of respondents reported 4-8 h use of cellphone daily 92% reported that the time mainly spent in chat tools 84% reported the habit of one-hand holding; After long-term use of cellphone, 38% experienced stiff and swollen fingers, red and swollen wrist, and/or finger joint nodules. In the field experiment, no symptoms of hand discomfort was observed after 2 h use of cellphone; but such symptoms was noted in about 10.0% of subjects after 4-6 h; and then up to 16.7% of subjects after 8-10 h. Subjects who played games or used chat tools had the highest risk to experience hand discomfort （13.3%）, while those who watched videos were at a lower risk. Conclusion The incidence of ＂cellphone disease＂ increases with the time of eellphone use. Habits like two-hand holding and multi-finger operating are more likely to induce ＂cellphone disease＂. Cellphone users should keep a good habit with proper postures, and have a rest whenever possible, so as to reduce the risk of ＂cellphone disease＂.
