In this study, a series of focus groups were conducted to gain an understanding of the nature of stress among Canadian Aboriginal women and men living with diabetes. Specifically, attention was given to the meanings Aboriginal peoples with diabetes attach to their lived experiences of stress, and the major sources or causes of stress in their lives. The key common themes identified are concerned not only with health-related issues (i.e. physical stress of managing diabetes, psychological stress of managing diabetes, fears about the future, suffering the complications of diabetes, and financial aspects of living with diabetes), but also with marginal economic conditions (e.g. poverty, unemployment); trauma and violence (e.g. abuse, murder, suicide, missing children, bereavement); and cultural, historical, and political aspects linked to the identity of being Aboriginal (e.g. 'deep-rooted racism', identity problems). These themes are, in fact, acknowledged not as mutually exclusive, but as intertwined. Furthermore, the findings suggest that it is important to give attention to diversity in the Aboriginal population. Specifically, Métis-specific stressors, as well as female-specific stressors, were identified. An understanding of stress experienced by Aboriginal women and men with diabetes has important implications for policy and programme planning to help eliminate or reduce at-risk stress factors, prevent stress-related illnesses, and enhance their health and life quality.
