大学新生网络成瘾、睡眠质量及日周期类型的现况调查

Internet addiction,sleep quality,and sleep-wake chronotype among first-year undergraduate students

目的调查大学新生中网络成瘾、睡眠质量及日周期类型的检出情况,并进行相关因素分析。方法通过网络调查于2019年9—12月对四川大学2019年9157名新入学本科生进行心身健康问卷调查,采用杨氏网络成瘾问卷、匹兹堡睡眠质量指数、清晨型-夜晚型问卷,分别调查网络成瘾、睡眠质量以及日周期类型的检出情况。采用Logistic回归分析,调整人口学分类(性别、年龄)、睡眠质量及睡眠-觉醒昼夜节律间的相互影响后,分析网络成瘾的独立相关因素。结果回收得到有效应答问卷7457份,网络成瘾总检出率为8.86%(661/7457),其中女性网络成瘾检出率为10.04%(348/3466),男性网络成瘾检出率为7.84%(313/3991),睡眠质量问题总检出率为11.73%(875/7457);日周期类型为夜晚型、中间型、清晨型的检出率分别为:54.73%(4081/7457)、43.02%(3208/7457)、2.25%(168/7457)。采用Logistic回归分析,调整相关因素的相互影响后,性别(女性OR=1.26)、睡眠质量(OR=4.12)及日周期类型(中间型OR=0.37、清晨型OR=0.24)仍为网络成瘾的独立相关因素。结论大学生中女性网络成瘾患病率高于男性,多数学生的日周期类型为中间型及夜晚型,在控制睡眠质量影响的情况下生物节律日周期类型仍是网络成瘾的独立相关因素,提示睡眠生物节律在网络成瘾的机制中可能具有一定作用。

Objective This study aims to investigate the prevalence of internet addiction,morningness-eveningness preference of sleep-wake chronotype,and sleep quality and the correlates of internet addition among first-year undergraduate students.Methods The newly admitted undergraduates(n=9157)of a comprehensive university in 2019 were invited to participate in an online survey from September 2019 to December 2019.The Young′s 20-item Internet Addiction Test,the Pittsburgh sleep quality index,and the Morningness-Eveningness Questionnaire(MEQ)were used to measure internet addiction,sleep quality,and the types of morningness-eveningness preference respectively.Logistic regression analysis was used to analyze factors independently related to internet addiction with demographic variables(i.e.,gender and age),sleep problems,and morningness-eveningness preference adjusted.Results A total of 7457(81.4%)newly admitted undergraduates completed the questionnaires.The prevalence of internet addiction in the total sample was 8.86%(661/7457),while the corresponding figures were 10.04%(348/3466)in female students and 7.84%(313/3991)in male students.The prevalence of sleep problems was 11.73%(875/7457).For chronotype,the prevalence of evening type,intermediate type,and morning type was 54.73%(4081/7457),43.02%(3208/7457)and 2.25%(168/7457)respectively.After adjusting the interaction of related factors in the logistic regression analysis,being female(OR=1.26),having sleep quality(OR=4.12),and having sleep-wake chronotype of intermediate type(OR=0.37)and morning type(OR=0.24)were independently associated with internet addiction.Conclusions Female students had higher prevalence of internet addiction than male students.Majority of students had a chronotype of intermediate or evening type.The sleep-wake chronotype was independently associated with internet addiction after controlling sleep quality,which indicated that sleep biological rhythm may be involved in the mechanism of the occurrence of internet addiction.
