Glycemic Factors Related to Depression in Adults with Type 1 Diabetes

Objective: To compare glycemic factors (home glucose monitoring, glucose variability, A1c) in adults with type 1 diabetes (T1D) with probable depression to those without depression in a real world setting. Methods: Adults with T1D at our diabetes center are routinely screened for depression with the PHQ2. If the PHQ2 score is u003e3, PHQ9 is completed. Medical records were reviewed including device downloads for adults with PHQ9 scores =10 (“depressed”) and age-matched “not depressed” controls (PHQ2 scores =3). Patients with T1D duration 2 , hemoglobinopathy or dementia were excluded. Results: Of 1292 adults screened, 83 (6.4%) were depressed, and compared to an age-selected group of 171 non-depressed T1D adults (age range 18-72 years, 86% white, 8% black, 99% non-Hispanic, 42% Medicaid). Depressed [mean (SD) PHQ9 score 16.8 (4.3)] did not differ from non-depressed on age [41.7 (15.6) vs. 41.8 (15.7) years], BMI [29.3 (8.8) vs. 28.9 (6.2) kg/m 2 ], T1D duration [21.2 (13.4) vs. 22.0 (15.0) years], or % male [42.2 vs. 40.9]. Meter downloads were available for 215/254 patients (74% of depressed, 90% of non-depressed). The depressed group had higher A1c [9.6% (2.3) vs. 8.6% (1.8) p Conclusion: Adults with T1D and probable depression had higher A1c, less meter use, fewer glucose readings/day, but no difference in glucose variability (% CV) or hypoglycemia ( Disclosure I.
