Facilitating barriers: Contextual factors and self-management of type 2 diabetes in urban settings

Urban environments create unique challenges for the management of type 2 diabetes (T2D). City living is associated with unhealthy occupational, nutritional, and physical activity patterns. However, it has also been linked to behaviours that promote health, such as walking and cycling for transportation. Our research is situated at the intersection of these contradictory findings. We ask: What aspects of urban living impact the ability of those living with diabetes to reach optimal health? What contextual and structural factors influence how barriers are experienced in the everyday lives of those living with T2D? We conducted semi-structured interviews with 29 individuals living in Toronto and Vancouver. Interviews were recorded, transcribed, and systematically coded for themes and sub-themes. In addition to affirming readily acknowledged barriers to diabetes management, such as accessing healthy, culturally appropriate food and the cost of management, our findings suggest that the unpredictable nature of urban living creates barriers to routinizing self-management practices. As large, cosmopolitan centres with an abundance of activities on offer, cities pulls people away from home, making adherence to self-management recommendations more difficult. Moreover, our findings challenge commonly held assumptions about the mutually exclusive and static nature of barriers and facilitators. Public transit, a readily acknowledged facilitator of healthy living, can be experienced as a barrier to diabetes management. Participants report intentional non-adherence to their medication regimens for fear of hypoglycemia in subway or traffic delays. While the stimulating nature of cities promotes walkability, it produces barriers as well: participants partake in more restaurant eating than they would if they lived in a rural area and were home to cook their own meals. Understanding how barriers are experienced by people living with diabetes will help mitigate some of the unintended consequences associated with various contextual factors. We recommend that healthcare professionals acknowledge and support people with T2D in routinizing self-management and developing contingency plans for the unpredictability and complexity that urban living entails. We suggest further research be carried out to develop contextually-tailored municipal policies and interventions that will support self-management and improve outcomes for individuals living with T2D in urban settings.
