研究者蒂姆•阿尔托夫表示：“举例来说，瑞典爱运动和不爱运动的人之间的差距最小……同时也是肥胖率最低的国家之一。”

The United States and Mexico both have similar average steps, but the US has higher activity inequality and obesity levels.

美国和墨西哥平均走路步数相似，但美国活动不均等的程度和肥胖率都更高。

The researchers were surprised that activity inequality was largely driven by differences between men and women.

研究者还惊讶地发现，活动不均等的程度与男女差异有很大的关联。

In countries like Japan - with low obesity and low inequality - men and women exercised to similar degrees.

比如，日本的肥胖率和活动不均等程度都较低，男性和女性锻炼的频率接近。

But in countries with high inequality, like the US and Saudi Arabia, it was women spending less time being active.

而在美国和沙特阿拉伯这些活动不均等程度较高的国家，女性往往花更少时间锻炼。

Jure Leskovec, also part of the research team, said: "When activity inequality is greatest, women's activity is reduced much more dramatically than men's activity, and thus the negative connections to obesity can affect women more greatly."

研究者卓尔•莱斯科夫认为：“当活动不均等最严重的时候，女性锻炼比男性要少得多，因此女性受到肥胖的影响要比男性更大。”
