A new medical study has shown strong evidence that high BMI can cause depression.

Researchers at the University of South Australia published a detailed study of these findings in the State Journal of Epidemiology, examining 73 genetic variants associated with a high body mass index that causes weight-related conditions such as diabetes or heart disease. At the same time they looked at 14 species Of the options associated with obesity but not related to these health problems themselves.

"The strength of our study design is the ability to focus on the effects of a high body mass index (BMI), rather than the dietary or social effects that are usually associated with obesity," said Dr. Helena Hebobnin, professor at the University of South Australia's School of Medicine .

The researchers took data from 500,000 participants between the years 37 and 73, where the frequency of the current genetic obesity variable, hospital acceptance rate and self-reported depression rate were contrasted. The team compared genetic data from more than 48,000 people who reported depression with a more controlled group of 290,000 people.

"These genes are similar to depression, such as those associated with high body mass index and diabetes," told Hyaponin The Morning Herald.

The team found a strong link between people with high BMI and depression. The study found that for each 4.7-point increase in BMI, the risk of depression was 23% for women and 18% for the general population.

"Obesity and depression are two global health problems that have a significant impact on life and are expensive for healthcare services," said Dr. Jess Terrell, a doctor at the University of Exeter University School of Medicine. We have long known that there is a link between the two, but it is not clear whether obesity causes depression or vice versa, and even if it is overweight or related health problems that can cause depression.

"Our strong genetic analysis concludes that the psychological effect of obesity is likely to cause depression, which is important in helping to reduce depression, making it difficult for humans to adopt a healthy lifestyle," he said.
