“…Although the pathophysiologic mechanisms of excessive online gaming are not fully understood, recent studies suggest a relationship between cardiac autonomic regulation and video gaming (Ivarsson et al, 2009(Ivarsson et al, , 2013. During video game play, increased heart rate was observed in male adolescents regardless of violent content (Ivarsson et al, 2013).…”

“…While the effects of excessive EME have been studied in the context of physical and psychological aspects of health and well-being (17)(18)(19)(20), few have examined their effects on sleepiness, sleep patterns and disturbances. Thus, more EME (television or computer) was related to later bedtime, shorter sleep duration and higher level of fatigue; and nighttime cellular phone use was strongly associated with daytime fatigue (8,9).…”

“…18 In addition, because many families are using television as part of the child's bedtime routine, television viewing may displace more soothing bedtime rituals. Television viewing at bedtime, regardless of location, may result in increased autonomic activation due to hyperarousal 19 or disrupted melatonin production via brightly lit screens. [20][21][22] To the best of our knowledge, no published studies to date have explored the roles played by content type, timing, and co-use in media-related sleep problems.…”

WHAT'S KNOWN ON THIS SUBJECT:Media use has been shown to negatively affect child sleep, especially in the context of evening use or with a television in the child's bedroom. WHAT THIS STUDY ADDS:Increased sleep problems were observed in preschool-aged children for each additional hour of daytime violent media content or evening media use. No such effect was observed with nonviolent daytime use. abstract BACKGROUND: Media use has been shown to negatively affect a child's sleep, especially in the context of evening use or with a television in the child's bedroom. However, little is known about how content choices and adult co-use affect this relationship. OBJECTIVE:To describe the impact of media content, timing, and use behaviors on child sleep. METHODS:These data were collected in the baseline survey and media diary of a randomized controlled trial on media use in children aged 3 to 5 years. Sleep measures were derived from the Children's Sleep Habits Questionnaire. Media diaries captured time, content title, and co-use of television, video-game, and computer usage; titles were coded for ratings, violence, scariness, and pacing. Nested linear regression models were built to examine the impact of timing, content, and co-use on the sleep problem score. RESULTS:On average, children consumed 72.9 minutes of media screen time daily, with 14.1 minutes occurring after 7:00 PM. Eighteen percent of parents reported at least 1 sleep problem; children with a bedroom television consumed more media and were more likely to have a sleep problem. In regression models, each additional hour of evening media use was associated with a significant increase in the sleep problem score (0.743 [95% confidence interval: 0.373-1.114]), as was daytime use with violent content (0.398 [95% confidence interval: 0.121-0.676]). There was a trend toward greater impact of daytime violent use in the context of a bedroom television (P ϭ .098) and in low-income children (P ϭ .07). CONCLUSIONS:Violent content and evening media use were associated with increased sleep problems. However, no such effects were observed with nonviolent daytime media use.
