TOPLINE:
Mental health disorders increase the likelihood of developing chronic diabetic complications and vice versa across all age groups in patients with type 1 diabetes (T1D) or type 2 diabetes (T2D).
METHODOLOGY:
- Researchers used a US national healthcare claims database (data obtained from 2001 to 2018) to analyze individuals with and without T1D and T2D, who had no prior mental health disorder or chronic diabetic complication.
- The onset and presence of chronic diabetic complications and mental health disorders were identified to determine their possible association.
- Individuals were stratified by age: 0-19, 20-39, 40-59, and ≥ 60 years.
TAKEAWAY:
- Researchers analyzed 44,735 patients with T1D (47.5% women) and 152,187 with T2D (46.0% women), who were matched with 356,630 individuals without diabetes (51.8% women).
- The presence of chronic diabetic complications increased the risk for a mental health disorder across all age groups, with the highest risk seen in patients aged ≥ 60 years (hazard ratio [HR], 2.9).
- Similarly, diagnosis of a mental health disorder increased the risk for chronic diabetic complications across all age groups, with the highest risk seen in patients aged 0-19 years (HR, 2.5).
- Patients with T2D had a significantly higher risk for a mental health disorder and a lower risk for chronic diabetic complications than those with T1D across all age groups, except those aged ≥ 60 years.
- The bidirectional association between mental health disorders and chronic diabetic complications was not affected by the diabetes type (P > .05 for all interactions).
IN PRACTICE:
“Clinicians and healthcare systems likely need to increase their focus on MHDs [mental health disorders], and innovative models of care are required to optimize care for both individuals with type 1 diabetes and those with type 2 diabetes,” the authors wrote.
SOURCE:
The study, led by Maya Watanabe, Department of Biostatistics, University of Michigan, Ann Arbor, Michigan, was published online in Diabetes Care.
LIMITATIONS:
The study relied on International Classification of Diseases 9th and 10th revision codes, which might have led to misclassification of mental health conditions, chronic diabetes complications, and diabetes type. The data did not capture the symptom onset and severity. The findings may not be generalizable to populations outside the United States.
DISCLOSURES:
The study was supported by the Juvenile Diabetes Research Foundation (now Breakthrough T1D). Some authors reported receiving speaker or expert testimony honoraria and research support, and some declared serving on medical or digital advisory boards or as consultants for various pharmaceutical and medical device companies.
