研究发现 超重可能会导致抑郁

Being overweight can cause depression even when no other health problems exist, according to a study released last Tuesday by the University of Exeter.
英国埃克塞特大学上周二发布的一项研究显示，即使在没有其他健康问题的情况下，超重也会导致抑郁。

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.
由埃克塞特大学和南澳大利亚大学组成的联合研究团队，分析了英国生物医学库中超过4.8万名抑郁症患者，并与另外一组超过29万名抑郁症患者进行了对比。

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.
尽管此前有研究发现，肥胖人群更容易抑郁，但该研究团队发现，如果身体质量指数（BMI）较高，不管有没有因为肥胖引起其他健康问题，都更容易导致抑郁。

"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.
埃克塞特大学医学院的杰斯·泰瑞尔博士表示：“我们通过基因分析得出，肥胖对心理的影响可能会导致抑郁。”

"This is important to help target efforts to reduce depression, which makes it much harder for people to adopt healthy lifestyle habits."
“这对于降低抑郁症很重要，因为肥胖使得人们很难养成健康的生活习惯。”

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.
研究人员利用精神病学基因组协会的数据，通过另一个大型队列研究来验证这一结果，得出了基本一致的结论。

The study has been published in the International Journal of Epidemiology.
这项研究成果发表在了《国际流行病学杂志》上。
