Résumé
Objective@#To investigate the association of Internet gaming disorder (IGD) and sleep quality in adolescents of Xi an, thereby providing theoretical evidence for prevention of IGD and improvement of sleep quality of adolescents.@*Methods@#A total of 1 181 adolescents from 3 middle schools of Xi an were randomly selected between August, 2019 and February, 2020. These adolescents were assessed by a series of questionnaires, including basic information questionnaire, IGD and Insomnia Severity Index (ISI). Univariate analysis and multivariate Logistic regression model were used to evaluate the association between IGD and insomnia.@*Results@#Among 929 junior middle school students who participated in online games and the IGD Diagnostic Questionnaire was filled out in the past 12 months, the prevalence of IGD was 20.0%(186). Univariate analyses indicated that gender,whether single family, whether they living with their parents, whether they were addicted to online games, whether they could control the time of online games, and the severity of insomnia influenced IGD ( χ 2=17.11, 8.33, 202.92, 91.23, 29.06, P <0.05). The multivariate Logistic regression of the total population showed that participating in online games was not associated with the severity of insomnia ( OR = 1.62 , 95% CI =0.92-0.85, P >0.05). The people who participated in online games in the past 12 monthsthe severity of insomnia was positively correlated with the risk of IGD ( OR =3.56，95% CI =1.92-6.61, P <0.01).@*Conclusion@#Internet gaming disorder become a severe situation in the middle school students. The severity of insomnia might become the risk factor of IGD, so social should pay more attention to the prevention of internet addiction.
