Depression and severe dysglycemia are linked bidirectionally in patients with type 1 diabetes, according to a study involving >3,700 individuals. Participants had type 1 diabetes, as well as depression and severe dysglycemia requiring an ER visit or hospitalization between 1996 and 2015. Investigators looked at how depression impacted severe dysglycemia, and vice versa. Among the results:
- 41% of patients had depression, 11% hyperglycemia, and 20% hypoglycemia.
- Patients with depression had >twice the risk of severe hyperglycemia, and an 89% increased risk of severe hypoglycemia.
- The associations were strongest within the first 6 months of depression diagnosis, >7 times, and >5 times, respectively.
- They remained strong 1-year post-diagnosis, >5 times, and >4 times, respectively.
- After severe dysglycemia episodes, hyperglycemic and hypoglycemic events were linked with >twice and 74% increased risk of depression, respectively.
