Complicated relationship between depression and obesity. Doctors for years looking for an actual association between depression and obesity. Now a recent study adds new evidence.
Both conditions are significant global health problems. Prior studies have shown that overweighted or obese individuals are more likely to develop depression than normal. While other reviews didn’t find complete evidence indicating that obesity causes depression.
To better understand this association, scientists from the University of Exeter in the United Kingdom worked with researchers from the University of South Australia. The results of their findings are published this week in International Journal of Epidemiology.
The researchers wanted to know whether a higher body mass index was associated with a raised risk of depression. For the study, the scientists collected genetic and medical data from 48,000 people who were suffering from depression. The team then compared that data with 290,000 controls.
lead author Dr. Jess Tyrrell said: “Obesity and depression are both global health problems that have a major impact on lives and are costly to health services.”
“We’ve long known there’s a link between the two, yet it’s unclear whether obesity causes depression or vice versa, and also whether it’s being overweight in itself or the associated health problems that can cause depression.
They found that a higher body mass index (BMI) was associated with a higher risk of depression. They also says that this link was greater among women compared to men.
“Our robust genetic analysis concludes that the psychological impact of being obese is likely to cause depression,”
