Fetma causes depression even if there are no associated health problems, a new study has found.
Jointly led by University of Exeter and University of South Australia, found a genetic analysis to simply have a higher than average body mass index can cause depression.
According to the researchers, this is a result of the psychological effect of being overweight.
The study used data from the British biobank that belonged to 48,000 people with depression and compared it to more than 290,000 people without depression.
The link between both health conditions was investigated by separating the psychological part of obesity from related health problems.
The result was verified using data from the psychiatric genomic consortium, which gave the same conclusion.
Dr Jessical Tyrrell, a professor at the University of Exeter Medical School, said that the study has helped clarify the confusion about whether obesity causes depression or vice versa, and whether it is overweight in itself or the associated health problems that can cause depression . “
She added:” Our robust genetic analysis draws the conclusion that the psychological effect of being overweight can cause depression. This is important in helping to focus on depression efforts, which makes it much more difficult for people to adopt healthy lifestyle habits. “
Earlier this year, the Public Health GP called on the GP to regularly record the patients’ BMI as part of their long-term vision plan to combat adult obesity.
