肥胖如何衡量？

The study did not look at the reasons behind the increases, but "income is a big driver. Age is a big driver," Ward said. States with younger people have lower obesity rates because people usually "gain weight as they age."
沃德表示，这项研究并没有考虑肥胖率增长背后的原因，但是“收入和年龄是主要因素。”年轻人较多的州肥胖率较低，是因为人们通常“随着年龄增长发胖。”
The state with the lowest obesity rate will be Colorado, which has always had lower rates. Ward said people in Colorado do a lot of outdoor activities, and they may have higher income. He added that living at higher elevations8, like Colorado might also influence the results. "There may be something about having to take a little extra energy to do everything at a higher altitude" that keeps weights lower, he said.
肥胖率最低的州将会是科罗拉多州。该州的肥胖率一直较低。沃德表示，科罗拉多州的人们从事多种户外活动，而且他们的收入可能更高。他还表示，生活在科罗拉多州这种海拔较高的地区可能也会影响结果。他说，在高海拔地区做任何事情都需要花费额外精力，这使得体重更轻。
The study was paid for by the JPB Foundation, which studies poverty and problems in society.
