Aim
Time preferences, i.e. individualsâ degree of patience/impatience in intertemporal choice, have been found to be associated with suboptimal health behaviours and health outcomes such as smoking, physical inactivity, unhealthy food intake and obesity. In this systematic review, we aimed to synthesise reported associations between time preferences, diabetes selfâmanagement behaviours, including use of diabetes technology, and outcomes.
Methods
We searched MEDLINE, EMBASE, PsycINFO, CINAHL, EconLit and all databases in the Web of Science Core Collection. Peerâreviewed studies of people with diabetes that included at least one diabetesârelated behaviour or outcome and a measure of time preferences were included. NonâEnglish language studies were excluded.
Results
A total of 961 records were identified, of which 12 articles were included. Three studies analysed both timeâconsistent and timeâinconsistent preferences, three studies solely analysed timeâinconsistent preferences and six studies did not explicitly define a time preference model. Measured outcomes across studies included selfâcare activities, such as medicationâtaking, exercising and eating a healthy diet, and biomedical outcomes, such as HbA1c and diabetesârelated complications. There were 10 crossâsectional studies and two panelâdata studies. No studies explicitly analysed the relationship between time preferences and diabetes technology use.
Conclusions
Associations between measures of time preferences, diabetes selfâmanagement behaviours and clinical outcomes exist. Higher discount rates determined by both timeâconsistent and timeâinconsistent models predict less diabetesârelated selfâcare and worse outcomes. These findings may add to explanations of the observed variation in diabetesârelated health and provide new insights for tailoring interventions and policies aimed at improving diabetes selfâmanagement.
