Type 2 diabetes would increase the risk of depression in people under 40

Researchers at the University of Melbourne have conducted a study on the link between depression and type 2 diabetes. According to them, more and more diabetics under the age of 40 are affected by this mental disorder.

Mheart disease, vision loss, kidney failure… If diabetes can cause complications on our physical health, it could also have repercussions on our mental health. In any case, this is what researchers from the University of Melbourne report, who conducted a study published on September 5 in the scientific journal Diabetology. According to them, patients with diabetes type 2 (the most common type of diabetes, which usually appears with age) and those under 40 years old would be 50% more likely to suffer from depression compared to patients over 50 years old. And this whether they have other underlying diseases or not.

To reach this worrying conclusion, scientists combed through the electronic medical records of almost 1.4 million patients in the UK and US, all with type 2 diabetes, over a period of 11 year. Unpublished and important research, since it is the first to examine the prevalence of depression at the time of diagnosis of type 2 diabetes (T2DM) on a scale representative of the population, specifies Top Health.

Surprising increase in depression rates among diabetics

Our findings clearly highlight the mental health implications of developing type 2 diabetes at a young age and the importance of efforts to prevent diabetes early in life.“says Professor Sanjoy Paul, who led the study. His research also shows a surprising increase in rates of depression at the time of T2D diagnosis in the UK and the US across all age groups. , rising respectively from 29% and 22% in 2006 to 43% and 29% in 2017.

But how to explain this increase of around 3 to 4% each year? As summarized by our colleagues from Slate and Times, this could be linked to the increase in the number of people developing this disease before the age of 40. Indeed, even if type 2 diabetes tends to appear around the age of 58 in our neighbors across the Channel, more and more “young people” are developing the disease in turn, in particular because of the rise in obesity rate and increasingly unhealthy lifestyles adopted by the population (cigarettes, alcohol, ultra-processed foods, etc.).

If this study finds a link between diabetes and mental health disorders, the scientists say that more research will be needed to find ways to reduce the risk of depression in carriers.
