Abstract

<p>A cross-sectional study was conducted to clarify the relationship between Internet Gaming and sleep, lifestyle habits, schoolwork, and mood among elementary school students. Internet Gaming Disorder (IGD) was assessed using the Diagnostic and Statistical Manual of Mental Disorders (DSM-5th edition). The relationship between IGD and each factor was assessed using a logistic regression analysis. A total of 19.4% of boys and 10.6% of girls in the low grades (grades 1-3) and 15.1% of boys and 7.6% of girls in the high grades (grades 4-6) were diagnosed with IGD. A game time of＞2 h was significantly associated with difficulty falling asleep, difficulty waking up, lack of deep sleep, daytime sleepiness, nightmares, skipping breakfast, dislike of studying and sports, lack of motivation, and irritability. IGD was independently associated with lower grades, male sex, use of game consoles in bed, possession of media devices, lack of usage rules, and late bedtime. Increases in the odds ratio for IGD were larger in lower grades than in higher grades with delayed bedtime and in girls than in boys when gaming in bed. In the future, it would be beneficial to accumulate evidence and create guidelines for using gaming devices.</p>
