"Investigators from the CDC, Emory University and Andrews University analyzed survey data from 552 adults in the Seattle-Tacoma area, according to the study, published in the October issue of the American Journal of Preventive Medicine.
The hypothesis was that male video-game players have a higher body mass index — the measure of a person’s weight in relation to their height — and women have “a greater number of poor mental health days” versus nonplayers, said Dr. James B. Weaver III of the CDC’s National Center for Health Marketing. The hypothesis was correct, he said."
Whew, I'm glad Dr. Weaver III settled that. Everyone loves a good conclusive study.
Why do you think they hypothesized about the men's BMI and the women's mental health? Only Dr. Weaver knows for sure (actually, it just turned out that the data didn't support a BMI difference for women or a mental health difference for men). Another interesting thing Dr. Weaver stated was that women use video games as a "digital self-medication" but if that's the case, then the egg must come before the chicken and the only conclusion is that women are finding video games as a way to cope with depression. Would he prefer actual medication to self-medication?
Reading beyond the mainstream articles for more details turned out additional caveats. The survey to gather data was performed only online, where 18% of the population requested voluntarily responded, of which an impressive 44.3% classified themselves as video game players. I don't believe that's representative of the population in general, especially considering the number of consoles sold by the major manufacturers.
