A new study shows that the body mass index (BMI) is more than 30 associated with increased risk of low depression.
A team from South Australia University and Exeter University (UK) has studied a case of over 48,000 people suffering from depression and belonging to the UK Biobank squad. This long-term, long-term study provides genome data access to British residents aged 37-73.
The researchers also formed a management group that includes 290,000 people born between 1938 and 1971.
Using this information, they analyze the cells that are associated with higher BMI and lower risk of diseases such as diabetes, to check if there were health problems associated withobesity was on the origin of the depression.
The society seems more important among women than in men.
We talk about obesity from BMI More than 30 kg / m2, BMI is calculated by dividing weight in kilograms by height in square meters.
Those researchers noted very thin men and low BMI is more likely to be depressed than those with a weight that are considered to be the norm or very thin women.
"The current obesity epidemic is a major concern"explained Professor Elina Hypponen, who co-directed the study."With low depression, it costs $ 1 trillion of the international community every year, according to estimates. "
"Our research shows that stress overweight only increases the risk of chronic diseases such as cancer and cardiovascular problems: it can also lead to depression."
The study is not the first to establish a link between BMI and depression. In 2016, researchers have already come to the conclusion that a woman with BMI between 30 and 34.9 faces the risk of depression compared to a woman with weight in the norm. Researchers at Brigham & Women in Boston, USA, presented the results last year suggesting that Women with high BMI also pose a risk of post-depression more importantly.
A study of the Dutch in the Europe Europe on Obesity 2017 also suggested overweight children aged 8 or 13 are three times more likely to fall into depression later in life.
