A systematic review of the relationship of diabetes mellitus, depression, and missed appointments in a low-income uninsured population.

The purpose of this systematic literature review was to determine the relationship between the diagnosis of diabetes and depression and missed appointments in a low-income, uninsured, racially heterogeneous, adult population. Research demonstrates that individuals with diabetes have an increased incidence of depression across socioeconomic and racial groups. Low-income individuals have an increased prevalence of depression. The cost and burden of diabetes are greatly increased among individuals with both diabetes and depression versus diabetes alone. The prevalence and effects of diabetes and depression in a low-income, uninsured, racially heterogeneous population have not been determined. Further research to explore the relationship of diabetes, depression, and missed appointments in this vulnerable population is needed before effective treatment models can be developed. Longitudinal studies are also needed to determine the cause and effect between diabetes and depression among all populations.
