Targeting obesity to reduce the risk for type 2 diabetes and other co-morbidities in African American youth: a review of the literature and recommendations for prevention.

Over the last decade, the prevalence of obesity has continued to rise within the adolescent population of the US. Data show that African American youth are disproportionately affected by the obesity epidemic due to their higher risk for obesity-related co-morbidities, such as type 2 diabetes. Interventions that target risk factors for obesity at the individual, family and community levels are needed in order to prevent the onset of type 2 diabetes and related complications. This article provides an overview of the prevalence of obesity and type 2 diabetes in African American youth, the pathophysiology of the disease, and the behavioural risk factors that have contributed to its high prevalence within the African American adolescent population. Successful intervention strategies that target modifiable risk factors, such as diet and physical activity, will be identified. Finally, recommendations for programmes to prevent the onset of type 2 diabetes within the African American adolescent population are presented.
