Diet. Higher proportion of Asians being first generation could be a confounding factor. I am sure Nigerians and other first generation are the same.
Then the second and third generations pick up bad eating habits, namely alcohol and eating out.
But from my trips back to my parents’ country, I see a lot of fat rich people and fat kids who have rich parents. In the US, I feel like I hardly ever see rich and fat people.
So it is probably a pendulum where you go from being poor and having to eat home cooked food and not having access to excess calories, and then you might pass on some of those good habits to your kids, but the grandkids will not have them. But then if you are in a social circle that is all relatively rich where being fit is valued, then you might start focusing on being fit rather than enjoying all the wealth you have.
