The presence of depression among people with diabetes can substantially increase health care costs and reduce health care utilization. This study aimed at further elucidating the factors underlying the relationship between depressive disorders and health care utilization among people with diabetes. Data were obtained from the 2019 Behavioral Risk Factor Surveillance System, and the sample was limited to people with diabetes (n = 22,642). The independent variable was assessed by a lifetime diagnosis of depressive disorder, including depression, major depression, dysthymia, or minor depression. The dependent variable was cost-related health care utilization assessed as a response (yes/no) to whether participants had not seen a doctor due to costs in the past year. Logistic regression models examined the association between depressive disorders and health care utilization, adjusting for covariates incorporating weighting to account for study design. Overall, 25.2% of the people with diabetes reported having had a depressive disorder in their lifetime. People with diabetes who had ever been diagnosed with a depressive disorder were more likely to have reported not seeing a doctor due to costs in the past year (adjusted odds ratio: 1.82 [1.49, 2.28]). Findings from this study suggest a need for further research regarding the relationship between depression and cost-related health care utilization among people with diabetes.
