> I would guess that there's a big divide between urban and rural area Bingo! 100% correct. Look at West Africa. Rural areas have a very low incidence of obesity/diabetes/HTN (though I think their rate of hyperlipidemia is about normal, which makes mechanistic sense). Urban areas have rapidly increasing rates of those diseases. I agree that public health campaigns, though helpful for raising awareness, are unlikely to succeed (at least, to a degree that you and I would consider successful). It's all about the money (economic advantages), which is why the tobacco tax appears to have worked so well. (Or, who knows, maybe it just takes 20 years of public health campaigns; I guess I can't honestly say for sure.)
