研究發現 超重可能會導致抑鬱

Being overweight can cause depression even when no other health problems exist, according to a study released last Tuesday by the University of Exeter.
英國埃克塞特大學上週二發佈的一項研究顯示，即使在沒有其他健康問題的情況下，超重也會導致抑鬱。

A team led by researchers from the University of Exeter and the University of South Australia, analyzed UK Biobank data from more than 48,000 people with depression and compared them to another group of more than 290,000 people.
由埃克塞特大學和南澳大利亞大學組成的聯合研究團隊，分析了英國生物醫學庫中超過4.8萬名抑鬱症患者，並與另外一組超過29萬名抑鬱症患者進行了對比。

While it has long been known that depression is more common in obesity, the team concluded that higher body mass index (BMI) can cause depression in itself, even in the absence of other health problems.
儘管此前有研究發現，肥胖人羣更容易抑鬱，但該研究團隊發現，如果身體質量指數（BMI）較高，不管有沒有因爲肥胖引起其他健康問題，都更容易導致抑鬱。

"Our robust genetic analysis concludes that the psychological impact of being obese is likely to cause depression," said Dr Jess Tyrrell, of the University of Exeter Medical School.
埃克塞特大學醫學院的傑斯·泰瑞爾博士表示：“我們通過基因分析得出，肥胖對心理的影響可能會導致抑鬱。”

"This is important to help target efforts to reduce depression, which makes it much harder for people to adopt healthy lifestyle habits."
“這對於降低抑鬱症很重要，因爲肥胖使得人們很難養成健康的生活習慣。”

The team tested their results in a second large-scale cohort, using data from the Psychiatric Genomics Consortium. They reached the same conclusion, verifying their results.
研究人員利用精神病學基因組協會的數據，通過另一個大型隊列研究來驗證這一結果，得出了基本一致的結論。

The study has been published in the International Journal of Epidemiology.
