It has been reported that Internet addiction is associated with substance dependence. Eating disorders have high rates of co-morbidity with substance use disorders. The relationship between Internet addiction and eating disorders was reported in a previous study.
To examine the hypothesis that Internet addiction is closely associated with bulimia. The hypothesis that depression mediates the relationship between Internet addiction and bulimia symptoms was also tested.
2,036 Chinese college students were assessed on Internet addiction, eating behaviors and depression. Binge eating, compensatory behaviors, weight concern, menarche and weight change were also reported. Multiple regression analysis was used to test the mediating effect of depression.
Internet addicts showed significantly higher scores on most subscales on EDI-1 than the controls. They reported significantly more binge eating, weight concern and weight change than the controls. Among all of the participants, depression was found to be a partial mediator in the relationship between Internet addiction and bulimia.
This survey provides evidence of the co-morbidity of Internet addiction and bulimia.

检验网络成瘾与暴食症密切相关的假设。还测试了抑郁是否在网络成瘾和暴食症状之间起中介作用的假设。
对 2036 名中国大学生进行网络成瘾、饮食行为和抑郁评估。还报告了暴饮暴食、补偿行为、体重担忧、初潮和体重变化。采用多元回归分析测试抑郁的中介效应。
与对照组相比，网络成瘾者在 EDI-1 的大多数分量表上得分明显更高。他们报告的暴饮暴食、体重担忧和体重变化明显多于对照组。在所有参与者中，抑郁被发现是网络成瘾和暴食症之间关系的部分中介因素。
本调查提供了网络成瘾和暴食症共病的证据。
