The study -- "Health-Risk Correlates of Video-Game Playing Among Adults" -- is being published in the October issue of the American Journal of Preventive Medicine.
The researchers surveyed 562 adults ranging in age from 19 to 90 in the Seattle-Tacoma area of Washington state. A total of 45.1 percent of those surveyed reported playing videogames.
The Seattle-Tacoma area -- home of Microsoft and Amazon -- was selected because it has the highest Internet usage level in the country.
Female videogame players reported greater depression and lower health status than female non-players while male videogame players reported a higher body mass index (BMI) and more Internet use time than male non-players.
"The only determinant common to both female and male video-game players was greater reliance on the Internet for social support," the study said.
"As hypothesized, health-risk factors -- specifically, a higher BMI and a greater number of poor mental-health days -- differentiated adult video-game players from nonplayers," said Dr. James Weaver of the CDC's National Center for Health Marketing.
"Video-game players also reported lower extraversion, consistent with research on adolescents that linked video-game playing to a sedentary lifestyle and overweight status, and to mental-health concerns," he said.
Most studies on videogame use and health have focused on adolescents. The study is one of the first to study the health-risk factors of videogame playing in adults.
