Hispanic Americans are fatter than the rest of us (and we're fat as hell): I examined 2002 Behavioral Risk Factors Surveillance System data on 247,964 Americans. Here are mean Body Mass Indexes by Hispanic ethnicity:
Mean Body Mass Index
(I wasn't able to figure out why their index is different from the one that ranges from the teens to the thirties). Adjusting for height, Hispanics are heavier than others, and the difference is about one-sixth of a standard deviation.
As everyone knows, obesity is associated with a long list of health problems, not to mention eye pollution. Mass immigration from the south is making us a less healthy society.
