Diabetes mellitus (DM) is a chronic condition affecting an estimated 422 million adults worldwide and 28.9 million adults in the US. DM can lead to increased risk of mortality and significant complications including amputation, blindness, cardiovascular disease, and kidney damage. The risk of developing these outcomes can be mediated by early diagnosis and treatment, such as by patient self-management by lifestyle changes and/or taking medication. However, outcome improvement depends on control of blood glucose levels, which in turn depend on adherence to treatment. Several psychosocial factors are known to affect treatment adherence for chronic conditions, one of which is stigma.
