最新研究顯示:空氣污染可致肥胖
A new study shows laboratory rats that breathed Beijing's highly polluted air gained weight and experienced cardiorespiratory and metabolic dysfunctions.
最新研究顯示，實驗室老鼠呼吸北京嚴重污染的空氣會造成體重增加，心肺和代謝功能紊亂。The Duke University-led study has published the result in the March issue of the Journal of the Federation of American Societies for Experimental Biology (FASEB).
這項由杜克大學領導的研究結果發表在美國實驗生物學會雜誌3月刊上。Zhang Junfeng, a professor of global and environmental health at Duke and a senior author of the paper, said the research aims to understand the factors leading to obesity besides diet and sports, reports.
據財新網報道，杜克大學全球環境健康教師、高級論文作者張俊峯表示，該項研究的目的是瞭解除了飲食和運動之外導致肥胖的因素。
In the study, pregnant rats and their offspring were placed in two chambers – one exposed to filtered air that removed most of the air pollution particles and the other to Beijing's highly polluted air.
研究中，懷孕小鼠及其後代被分置於兩室，一組接觸的是濾淨大部分污染顆粒物的空氣，另一組暴露於北京污染嚴重的空氣中。The research showed that the lungs and livers of pregnant rats exposed to the polluted air were heavier and showed increased tissue inflammation after only 19 days. The levels of LDL cholesterol, triglycerides, total cholesterol, and insulin resistance, a precursor of Type 2 diabetes, were higher. The research provides clear evidence that chronic exposure to air pollution increases the risk for developing obesity.
研究顯示，僅19天后，呼吸污染空氣的懷孕小鼠的肝臟和肺部變重、組織炎症變嚴重。這些小鼠的低密度脂蛋白膽固醇、甘油三酯、總膽固醇指標更高，2型糖尿病的先兆指標之一的胰島素抵抗也更嚴重。該研究爲長期暴露於污染空氣會增加肥胖風險提供了明確的證據。Zhang said it's highly possible that air pollution contributes to obesity, but the dietary and sports are still dominant factors.
張俊峯表示，很有可能空氣污染對肥胖有相當的影響，但是飲食和運動仍是占主導地位的因素。
