The findings are the same in either language. Americans are fatter than Canadians. In the United States, 34 percent of adults are obese (defined as having a body mass index of 30.0 or higher). In Canada, the figure is a substantially smaller 24 percent. Even after limiting the analysis to non-Hispanic whites, most of the gap remains: 33 percent of Americans are obese compared with 26 percent of Canadians.
