研究發現 胖子的大腦比同齡瘦子的老10歲!

推薦人: 來源: 閱讀: 3.21W 次

Being overweight in middle-age makes the brain age by 10 years, research by the University of Cambridge has found.
據劍橋大學的一項研究發現,中年肥胖者的大腦會比他們實際年齡老10歲。

The study, which scanned 473 brains, found changes in the brain structure of overweight people which are normally seen in those far older.
通過對473個人進行腦部掃描,這項研究發現,超重人士,尤其是那些年老人士的大腦結構有所變化。

The volume of white matter - the tissue that connects areas of the brain and allows information to be communicated between regions - shrunk far more in those with a Body Mass Index above 25. Shrinkage of parts of the brain is associated with a higher risk of cognitive decline and dementia.
對於那些身體質量指數在25以上的人,腦白質(連接大腦各區域的組織,並允許各區域之間進行信息的傳遞)萎縮的更嚴重。而大腦的收縮,意味着具有認知衰退和癡呆的高風險。

The Cambridge study found no differences in cognitive skills when participants underwent IQ tests. But the men and women will be scanned as they get older, to check for changes which indicate mental decline.
劍橋大學研究團隊對參與者進行了智商測試,沒有發現他們有認知能力下降的跡象。不過,隨着他們變老,將會再次掃描大腦以檢測智力是否有下降。

Human brains naturally shrink with age, but scientists are increasingly recognising that obesity - already linked to conditions such as diabetes, cancer and heart disease - may also affect the onset and progression of brain ageing.
我們的大腦自然地隨着年齡的增長而萎縮,但科學家們越來越認識到,肥胖除了已知與如糖尿病、癌症和心臟疾病等多種疾病相關之外,也可能影響大腦老化的發生與進展。

In the study of people aged between 20 and 87, researchers looked at the impact of obesity on brain structure across the adult lifespan.
在對一組20歲到87歲的參與者的研究中,科學家觀察了在整個成人壽命期限內,肥胖對大腦結構的影響。

Researchers divided the groups into two categories: lean and overweight, depending on whether their BMI was above or below 25. They found striking differences in the volume of white matter. Overweight individuals had a widespread reduction in white matter compared with lean people.
依據身體質量指數高於或低於25,研究員將參與者分成了兩組:偏瘦組和超重組。他們發現兩組的腦白質含量有驚人的區別。與偏瘦組相比,超重組的腦白質含量普遍都比較低。

The team then calculated how white matter volume related to age across the two groups. They discovered that an overweight person at 50 had a comparable white matter volume to a lean person aged 60.
之後,研究人員計算了兩組人員中腦白質含量和年齡的相關性。他們發現,一個50歲超重的人,他的大腦白質和一個60歲偏瘦的人的大腦白質數量是一樣的。

Researchers only observed these differences from middle-age onwards, suggesting that brains may be particularly vulnerable during this period of ageing.
研究人員只是從中年個體中發現了這些差異,這意味着隨着人們年齡增長,大腦會變得越來越脆弱。
