[Towards the development of an ethno-epidemiological study of type-2 diabetes and its complications]

The troubling evolution of Type 2 Diabetes into epidemic proportions bearing dramatic consequences has generated significant interest leading to a strong research focus and therefore the subject of several studies in recent years. This article examines Type 2 Diabetes Mellitus and its complications on the basis of a literature review addressing their epidemiological situation on an international scale--including indigenous peoples--and their socio-cultural determinants. This study reveals important ethnic disparities in terms of mortality and morbidity, as well as the multi-factored origin of this metabolic disorder, most notably among indigenous populations. Above and beyond the limits of prevention programmes, this literature review addresses the importance of reinforcing ethnoepidemiological studies among vulnerable peoples in order to improve our understanding of the emergence and development of this particularly complex pathological phenomenon
