In a groundbreaking study conducted in the United Kingdom, researchers have unveiled a significant connection between depression and the risk of developing type 2 diabetes. This novel research, recently published in the prestigious Diabetes Care journal and led by Diabetes UK, sheds light on a previously unclear relationship.
Until now, scientific studies primarily focused on the higher risk of depression among individuals with type 2 diabetes. However, this study is the first to establish depression as a risk factor for the development of type 2 diabetes. The findings are particularly crucial given the alarming global prevalence of both conditions.
Key Study Findings Of The Study
Population-Based Research
The study leveraged data from populations in both the UK and Finland, including 19,000 individuals with type 2 diabetes, 5,000 diagnosed with depression, and 153,000 who self-reported depression.
Complex Genetic Connection
The research identified seven shared genetic variants that contribute to both type 2 diabetes and depression. This discovery underscores the intricate relationship between these two conditions.

Beyond Obesity
While obesity is a known risk factor for type 2 diabetes, the study revealed that only 36.5 percent of the effect of depression on the development of type 2 diabetes could be attributed to obesity.
Behavioural Factors
The study suggests that common behavioural patterns among individuals with depression, such as smoking, physical inactivity, and overeating, significantly contribute to the risk of developing type 2 diabetes.

Medication Effects
People taking medication for depression often experience elevated cortisol levels and weight gain, which can further increase their susceptibility to type 2 diabetes.
The Global Impact
Globally, approximately 530 million adults are grappling with type 2 diabetes, according to data from the IDF Diabetes Atlas. This staggering statistic emphasises the importance of understanding the intricate relationship between depression and type 2 diabetes.
Elizabeth Robertson, Director of Research at Diabetes UK, expressed the potential impact of this knowledge on healthcare professionals. It could lead to improved care and support for individuals with a history of depression and potentially prevent additional cases of type 2 diabetes.
