Youth-onset type 2 diabetes among american indians and alaska natives.

Youth-onset type 2 diabetes has emerged as a significant public health concern for American Indians and Alaska Natives. Data from the National Institutes of Health longitudinal epidemiological study among the Pima Indians of southern Arizona and the Indian Health Service continue to document a rising incidence and prevalence of type 2 diabetes among American Indian and Alaska Native youth. Although national trends related to lack of physical activity and to unhealthy nutrition behaviors have contributed to the epidemic, the adverse conditions created by poverty, social injustice, trauma, and cultural disruption are also important in understanding the underlying causes for this public health crisis. This adverse environment is likely to provide little support for healthy nutrition and physical activity behaviors as well as other diabetes self-care behaviors. Known risk factors from the Pima Indian studies, such as intrauterine exposure to diabetes, bottle-feeding, and obesity, provide a basis for worthwhile intervention strategies. In this article, the author will review the current literature on the epidemiology of youth-onset type 2 diabetes among American Indians and Alaska Natives, discuss causes for the diabetes epidemic among American Indians and Alaska Natives, review risk factors for youth-onset type 2 diabetes in this population, and share promising youth physical activity promotion programs created and implemented specifically for American Indian and Alaska Native youth. However, more research on interventions to address the Native communities' psychosocial issues and concerns around youth-onset type 2 diabetes is urgently needed.
