报告估计，约1/3的成年人体育运动不足，每年530万人因此死亡。

A lack of exercise is now causing as many deaths as smoking across the world, a study suggests, the BBC reported.

The report estimates that about a third of adults are not doing enough physical activity, causing 5.3 million deaths a year. That equates to about one in 10 deaths from diseases such as heart disease, diabetes and breast and colon cancer.

The study found people in higher income countries were the least active. Researchers said the problem was now so bad it should be treated as a pandemic.

Researchers said tackling the problem required a new way of thinking, suggesting the public needed to be warned about the dangers of inactivity rather than just reminded of the benefits of it. They also said governments needed to look at ways to make physical activity more convenient, affordable and safer.

It is recommended that adults do 150 minutes of moderate exercise, such as brisk walking, cycling or gardening, each week.

据英国广播公司报道，一份研究报告显示，缺乏运动如今在全世界致死的人数和吸烟致死人数一样多。

该报告估计，约1/3的成年人体育运动不足，每年530万人因此死亡。这相当于心脏病、糖尿病、乳腺癌、结肠癌致死人数的1/10。

该研究发现，高收入国家的人运动最少。研究人员表示，该问题相当严重，应该当作流行病来看待。

研究人员表示，解决该问题需要换一种思维方式，并称应警告大众不运动的危害，而不是仅仅提醒他们不运动的益处。他们还说，政府应该寻找方法让体育运动更方便、更便宜、更安全。

成年人推荐每周做150分钟的运动，像散步、骑自行车、从事园艺活动等。
