New insights on diabetes mellitus and obesity in Africa-Part 2: prevention, screening and economic burden.

Evidence has been accumulating on the importance of the rising burden of diabetes mellitus on the African continent at an increasingly higher pace. In the first paper of this series of two companion papers, recent evidence on the prevalence, pathogenesis and comorbidities of obesity and diabetes mellitus in Africa were summarised. In this second paper, we focus on recent developments pertaining to the prevention, screening and the economic burden of diabetes and obesity on the continent. There are indications that awareness on diabetes and chronic diseases at large has increased in Africa in recent times. However, the care for diabetes largely remains suboptimal in most countries, which are not adequately prepared to face the prevention and control of diabetes, as the costs of caring for the condition pose a tremendous challenge to most local economies. Moreover, translation strategies to prevent and control diabetes and obesity, on the continent, are still to be evaluated.
