Diabetes mellitus is a chronic disease in which high blood glucose over long periods leads to diabetic complications including retinopathy, neuropathy, chronic kidney disease, and increased risk for cardiovascular events. Despite the availability of scientifically proven medical treatments, a significant number of patients with diabetes do not attain optimal glycemic control due to failure in self-management and nonadherence to medication. These behaviors appear irrational in terms of conventional economic theory. We applied the theory of behavioral economics, a new concept for clarifying irrational human behaviors, to investigating risk preferences in patients with diabetes. We found specific features in the responses of patients with diabetic complications. Many of these patients had low socioeconomic status, were reluctant to participate in the survey, and had difficulty in making decisions explicitly. Their choices under uncertainty often violated two axioms of the Expected Utility Theory (completeness and transitivity) and were therefore considered irrational, meaning that their choices were difficult to understand and differed from those that would be chosen by the majority of people. Health professionals should be aware of the propensity of such patients to make irrational decisions, which might be an important risk factor for the progression of diabetic complications.
