Obese people are more than twice as likely to survive infectious disease than under-weight patients, a study claims.

一項(xiàng)研究表明，肥胖者在傳染病中存活的幾率比體重過(guò)輕者高出兩倍以上。

The “obesity paradox” extends to pneumonia with obese patients up to 30 percent less likely to die.

“肥胖悖論”延伸至肺炎，肥胖者患肺炎死亡的可能性會(huì)降低30%。

Researchers looked at more than 18,000 patients admitted for infectious disease and their risk of death 90 days after discharge.

研究人員調(diào)查了1.8萬(wàn)多名因傳染病住院的病人，以及他們出院后90天內(nèi)的死亡風(fēng)險(xiǎn)。

They found underweight patients are 2.2 times more likely to die than normal weight people.

他們發(fā)現(xiàn)體重過(guò)輕的病人的死亡幾率比正常體重的病人高2.2倍。

But the overweight were 40 percent less likely to die than those at a normal weight and the obese 50 percent less likely.

The Danish team suggested obesity could be an evolutionary defense to infectious disease. Their findings have not yet been published.

丹麥研究小組認(rèn)為，肥胖可能是針對(duì)傳染病的進(jìn)化防御。他們的調(diào)查結(jié)果尚未公布。

A separate study looked at 1.7 million pneumonia patients in the US.

另一項(xiàng)研究調(diào)查了170萬(wàn)美國(guó)肺炎患者。

The Chinese researchers found the overweight were 23 percent more likely to survive than normal weight.
