A new link between body mass index and the risk of depression



The new study shows that a body mass index (BMI) greater than 30 is associated with a greater risk of depression.

A team from the University of South Australia and the University of Exeter (UK) examined a case of over 48,000 people suffering from depression and belonging to the British Biobank cohort. This large, long-term study provides access to genomic data for British residents between the ages of 37 and 73.

Researchers also set up a control group in which 290,000 people born in 1938-1971 took part.

Using this information, they analyzed the genes associated with a higher BMI and lower risk of diseases such as diabetes, to see if the health problems associated withobesity they were at the beginning depression.

The relationship seems more important among women than men.

We are talking about obesity from BMI more than 30 kg / m2, BMI calculated by dividing the weight in kilograms by the height in meters squared.

Scientists have noticed this very slim men and low BMI is more prone to depression than people with the weight defined in the standard or very thin women.

"The current obesity epidemic is very worrying"explains Professor Elina Hypponen, who co-directed the study."Depressed costs the international community $ 1 trillion annually, according to estimates".

"Our studies show that overweight not 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 method to establish a relationship between BMI and depression. In 2016, the researchers have already found that a woman with a BMI between 30 and 34.9 was doubly affected by depression in comparison with a woman of normal weight. Researchers from Brigham & Women & # 39; s Hospital in Boston, USA, presented the results of last year, suggesting that women with high BMI it also creates a risk postpartum depression more important.

The Dutch study presented at the European Obesity Congress 2017 in 2017 also suggested that overweight children at the age of 8 or 13, three times more often depressed later in life.
