The relationship between obesity and depression is closely linked, and the causal relationship has been controversial. Recently, scientists from the University of Exeter in the UK cooperated with Australian researchers on a series of surveys on this topic. Through a large genome study, they found that obese people have a higher risk of depression. This product was published in the International Journal of Epidemiology on May 13.
There are depression and heavy obesity in the world, causing several mega-yuan social costs per annum.
However, although obesity and depression often occur in people at the same time, everyone is not familiar with his / her; causal link between them. Whether people are very tough for fat or fat because of dementia. Because the causes involved are very difficult.
For example, obesity can cause a square problem, not with cough itself. On the other hand, some people think that there is a higher risk of obesity in obesity, because they sometimes eat reassurance. Finally, some people think that obesity and depression can be nourish and cause a bad circle.
So, in this study, scientists used to analyze genetic information so that they understand the causal relationship between obesity and depression. They want to find out more people with high-body body (BMI) indexes have the chance to develop mental disorders without other physical problems.
They used 48,000 patient numbers of patients; patients from the Health Database Database and compared with another 290,000 control. Overall, they found a strong interaction between high BMI and depression, and women showed a stronger society than men, similar to the results of previous studies. Women with BMI are higher to increase depression risk by around 21%, compared to about 8% for men.
The researchers used the genotypes of the topics to make healthy things. For example, they separated the genotypes that triggered behavior directly from the species of individuals with metallic disorders. They found that obese people are more likely to have bad symptoms, regardless of whether or not they have metallic or no. This situation is particularly noticeable in the numbers of women. In addition, they also found a number of changes that affect the test results, such as socio-economic status, drinking, smoking, and exercise.
"By investigating the results of a genetic study, we find that obesity is susceptible to mental health," said Dr. Jess Tyrrell, head of the study. "This is important for us to find ways to reduce mental health in the future."
However, the author also stated in the study that the relationship between obesity and dementia is still very difficult, and many questions are still waiting for a response.
"We have not yet been able to find the two-way causal relationship between BMI higher and mentally ill. We still need more research to investigate the serious impact of heavy insist on BMI and obesity. " … This article is from the Worldly Biotechnology of Missionary Disclosure Authorized.
