> I'd disagree and say that in overpopulated areas there is a higher rate of depression, obesity and psychological problems than in places with lower populations
What scope and scale are you looking at though? Because within first world countries such as the USA, psychological problems doesn't correlate much and obesity correlates negatively with population density. The problems you mention correlate much more with social and economic opportunities (or lack thereof) than population density itself.
