目的 调查医学生手机使用和依赖现状,研究手机依赖影响因素。方法 对某医科大学在校大学生(非毕业班)按年级进行分层整群抽样,每个专业最少一个小班,共抽取1 200名研究对象。采用自行设计的调查表对大学生手机使用情况及其影响因素进行分析。结果 2.92%的研究对象是手机成瘾者,智能手机拥有率为99.1%,手机成瘾指数量表(MPAI)得分(40.42±11.60)及四个维度得分在不同手机成瘾倾向分组之间差异有统计学意义(F值分别为2 086.023,641.844,593.352,397.734,602.621,P值均 ＜0.001),手机成瘾倾向高分组的检出率26.04%,其中女生手机成瘾倾向高分组检出率高于男生,差异有统计学意义(χ²=7.808,P=0.005)。经多元逐步线性回归分析,手机成瘾倾向MPAI得分与每天使用手机时长、学习压力、18∶00后使用手机时长、每天使用社交软件时长、性别存在线性关系。结论 医学生手机使用较为普遍,手机依赖现象较为严重,应该予以高度重视,引导其合理使用手机。

Objective To explore the mobile phone dependence of medical students and its influencing factors. Methods A total of 1200 subjects were selected by stratified cluster sampling in the undergraduates (non-graduating class) of a medical university.The self-designed questionnaire was used to analyze college students' mobile phone usage and its influencing factors. Results 2.92% of the subjects were mobile phone addicts.The smartphone ownership rate was 99.1%.The mobile phone addiction index (MPAI) score (40.42±11.60) and the four dimension scores were different among different mobile phone addiction tendency groups.The difference was statistically significant (F values were 2 086.023, 641.844, 593.352, 397.734,606.621, respectively, P values were all<0.001).The detection rate of the group with high mobile phone addiction tendency was 26.04%.The detection rate of the group with high mobile phone addiction tendency of female students was higher than that of male students.The difference was statistically significant (χ²=7.808,P=0.005).Multivariate stepwise linear regression analysis showed that there was a linear relationship between MPAI score of mobile phone addiction tendency and time spent using mobile phone, learning pressure, time spent using mobile phone after 18:00, time spent using social software every day and gender. Conclusion Medical students use mobile phones widely, and the phenomenon of mobile phone dependence is serious.Great importance should be given to guide them to use mobile phones reasonably.
