Obesity is associated with ___1___ health problems. But a new study finds that obese people may actually have an advantage in a specific medical situation: they’re less likely to die after surgery from certain respiratory complications than are their non-obese ___2___. The finding was published online by the Journal of Intensive Care Medicine. [Stavros Memtsoudis et al., "Mortality of Patients with Respiratory Insufficiency and Adult Respiratory Distress Syndrome after Surgery: The Obesity Paradox," link to come]

Obese surgical patients get slightly fewer cases of the conditions known as ___3___ and adult respiratory distress syndrome. And their risk of dying in the hospital from these breathing difficulties was less than a third that of the non-obese patients who developed the same respiratory challenges.

The researchers have various ideas about why. People carrying more weight could have more energy and nutritional stores to ___4___. Also, fatty tissue could be ___5___ some of the inflammation compounds that exacerbate the breathing issues. Or it may be more simple: doctors and nurses may expect their fatter patients to have a tougher time, so they give them more attention.

Further study could reveal why the bigger patients have the smaller risk—which might lead to strategies to lower the risk for those lower in weight.

肥胖會引發(fā)大量健康問題，然而最近的一項(xiàng)研究發(fā)現(xiàn)肥胖人士在某種情況下還是有點(diǎn)優(yōu)勢的：呼吸道綜合癥術(shù)后，肥胖人士的死亡幾率相對較低。這項(xiàng)發(fā)現(xiàn)由《重癥醫(yī)學(xué)雜志》在網(wǎng)上發(fā)布。 肥胖人士術(shù)后較少出現(xiàn)呼吸功能不全及成人呼吸窘迫綜合癥等情況。他們死于呼吸困難的幾率也比同樣有呼吸困難的正常體重的人要少1/3。 對于這種現(xiàn)象的成因，研究人員看法各異。有人認(rèn)為較胖的人囤積的能量和營養(yǎng)比較多，而且脂肪組織能吸收部分能使呼吸問題加劇的炎癥化合物。亦或者更簡單：醫(yī)生和護(hù)士認(rèn)為肥胖人士受到的折磨比較大，于是對他們關(guān)愛有加。 進(jìn)一步的研究會幫助我們揭開大胖子危險(xiǎn)小的奧秘——也為降低瘦小群體的危險(xiǎn)提供點(diǎn)借鑒。
