Abstract: Background　With the development of communication technology，mobile phone has become an essential and important carry-on article for college students.Mobile phone can make people more closely connect with each other.However，the development of the internet and various functions of mobile phone may lead to mobile phone dependency in some mobile phone users，especially in college freshmen，a group facing new life，and some of them having no pressures of entering graduate school.Objective　To investigate the association of mobile phone dependency with sleep quality，anxiety and depression in medical college freshmen.Methods　In June 2017，we conducted a survey in a cluster sample of 1 050 freshmen majoring in clinical medicine，stomatology or traditional Chinese medicine of Zhaoqing Medical College.Sociodemographic questionnaire developed by our research group，Chinese version of Mobile Phone Involvement Questionnaire （MPIQ），Pittsburgh Sleep Quality Index（PSQI），Self-rating Anxiety Scale（SAS），and Beck Depression Inventory（BDI）were used in the survey to assess the sociodemographic characteristics，mobile phone dependency，sleep quality，anxiety and depression，respectively.Multiple linear regression was used to examine the associations of mobile phone dependency with sociodemographic factors，sleep quality，anxiety and depression.Results　Altogether，944 of the students responded to the survey，obtaining a response rate of 89.90%.MPIQ score changed significantly according to sex，interest in learning，learning pressure，SAS score and BDI score（P<0.05）．Both interest in learning（r=-0.217），and learning pressure（r=-0.229）were negatively correlated with the MPIQ score（P<0.05）．But SAS score（r=0.114），BDI score（r=0.380）and neck circumference（r=0.110）were all positively correlated with the MPIQ score（P<0.05）．Multiple linear regression analysis showed that sex 〔β=2.713，95%CI（1.394，4.032）〕，interest in learning〔β=-3.040，95%CI（-4.353，-1.728）〕，learning pressure〔β=-3.108，95%CI（-4.374，-1.842）〕，SAS score〔β=2.492，95%CI（0.524，4.459）〕，and BDI score 〔β=1.517，95%CI（1.029，2.005）〕were independent influencing factors for MPIQ score（P<0.05）．Conclusion　Female is associated with higher possibility of having mobile phone dependency.So mobile phone dependency in this group should be paid more attention.Moreover，mobile phone dependency can cause anxiety and depression in medical college freshmen，which should to be highly concerned by families and schools.

摘要： 背景　随着通信技术的发展，手机已成为大学生必不可少的重要随身物品，手机可以使人与人之间的联系更紧密，但网络的发展，手机功能的多样性，尤其是无升学压力的大学新生，在面对新的生活时，手机的依赖性使用情况更加突出。目的　调查医学院校新生手机依赖性使用与睡眠质量、焦虑、抑郁的关系。方法　2017年6月，采用整群抽样方法，以专业为单位，选取肇庆医学高等专科学校的大一学生中临床医学专业、口腔医学专业、中医学专业共1 050人作为研究对象。收集其社会人口学资料，并采用手机依赖性问卷（MPIQ）、匹兹堡睡眠质量指数（PSQI）、焦虑自评量表（SAS）和贝克抑郁问卷（BDI）评估手机依赖性使用、睡眠质量、焦虑、抑郁情况。采用多元线性回归分析其之间的相关性。结果　共发放问卷1 050份，回收有效问卷944份，有效回收率为89.90%。不同性别、学习兴趣、学习压力、SAS、BDI情况的学生MPIQ评分比较，差异均有统计学意义（P<0.05）。学习兴趣（r=-0.217）、学习压力（r=-0.229）与MPIQ评分均呈负相关（P<0.05），SAS评分（r=0.114）、BDI评分（r=0.380）、颈围（r=0.110）与MPIQ评分均呈正相关（P<0.05）。多元线性回归分析结果显示，性别〔β=2.713，95%CI（1.394，4.032）〕、学习兴趣〔β=-3.040，95%CI（-4.353，-1.728）〕、学习压力〔β=-3.108，95%CI（-4.374，-1.842）〕、SAS评分〔β=2.492，95%CI（0.524，4.459）〕、BDI评分〔β=1.517，95%CI（1.029，2.005）〕是MPIQ评分的影响因素（P<0.05）。结论　女生手机依赖性使用情况较男性多，应该重点关注女生手机依赖性的使用情况。而手机依赖性使用与医学院校新生的焦虑、抑郁情况有关，需要引起家庭和学校的高度重视。
