- An estimated 5% of all adults around the world live with depression.
- Fluctuations in a person’s blood sugar levels are a known risk factor for depression.
- Researchers from Sun Yat-sen University believe reduced gray matter volume in the brain may mediate the link between blood sugar levels and depression risk.

Previous studies show that people with diabetes — a condition where a person has trouble keeping their blood sugar at a healthy level — have a two to three times
Now, researchers from Sun Yat-sen University in Guangzhou, China believe they have found a specific biological mechanism responsible for the correlation between blood sugar levels and depression.
Researchers reported that a reduced
This study was recently published in the journal Global Transitions.
Dr. Hualiang Lin, professor in the Department of Epidemiology at Sun Yat-sen University and corresponding author of this study, told Medical News Today they decided to study the impact of blood sugar on depression risk because previous studies have confirmed the correlation between fluctuations in blood sugar levels and the onset of depression.
“Additionally, extensive research has indicated a strong association between changes in brain structure and function and the development of depression. Therefore, the existing evidence strongly suggests that brain structure may play a mediating role in the comorbidity of diabetes and depression. Consequently, we conducted this study to further investigate this relationship,” Dr. Lin continued….
