Yeah!  There is really a lot of activity in this topic and in my opinion this is how it should be.  Now so many years, even decades, have passed when gaming addiction entered the life of mankind on such a scale after mass computerization, and then the mass distribution of all kinds of gadgets, smartphones on which you can play whenever and wherever you want. 
So the phenomenon of gaming addiction has become widespread and in general I like that the scientific community, sociologists and psychologists are really concerned about this global problem.  Of course, the problem needs to be solved somehow, but the solution itself will obviously be difficult.
 It is very correct that you find out the statistics on this issue. 
I hope it will help you in your much needed work.
