People with fat in their thighs and backsides may live longer because the fat traps harmful fatty particles and actively secreteshelpful compounds, according to a report published on Tuesday。

　　本周二发布的一项报告称，大腿和臀部脂肪较多的人可能更长寿，因为脂肪能锁住有害的脂肪颗粒，并可有效分泌出有益化合物。

　　Many studies have shown that people who accumulate fat around the abdomen and stomach are more likely to die of heart disease andother causes than bottom-heavy people, but the reasons are not clear。

　　很多研究表明，腹部脂肪多的人死于心脏病和其他疾病的可能性大于臀部脂肪多的人，但原因尚不清楚。

　　This may be because several different mechanisms are involved,said Kons tantinos Manolopoulos of Britain's University of Oxford。

　　英国牛津大学的康斯坦第诺斯马诺洛波洛斯说，这可能是几种不同机制共同作用的结果。

　　"It is the protective role of lower body, that is,gluteofemoral fat, that is striking," Manolopoulos wrote in theInternational journal of Obesity。

　　马诺洛波洛斯在发表于《国际肥胖期刊》的研究报告中写道：“下半身即臀部脂肪的保护性作用是惊人的。”

　　"The protective properties of the lower-body fat depot have been confirmed in many studies," he added。

　　他说：“下半身脂肪的保护特性已在很多研究中得到验证。”

　　Fat on the bottom and thighs appears to store excess fattyacids, said Manolopoulos, who reviewed published scientific studies forhis report。

　　马诺洛波洛斯为撰写这份研究报告查阅了已发表的相关科学研究。他说，臀部和大腿的脂肪储存了多余的脂肪酸。

　　Pear-shaped people also appear to have lower levels of compounds called in flammatory cytokines -- signaling chemicals involvedin the body's response to infection that also can play a role in heart disease and diabetes when they are inappropriately active。

　　此外，“梨形”身材的人体内的一种叫做“炎性细胞因子”的化合物的含量似乎更低。这种信号性化学物质与身体对感染的反应有关，而且如果它们过于活跃，可能会导致心脏病和糖尿病。
