Diabesity: an overview of a rising epidemic.
Sommaire de l'article
‘Diabesity’ is the term for diabetes occurring in the context of obesity. In this review, we will overview the latest epidemiological data available describing the rising prevalence, health impact and economic impact of diabesity. We will also outline the measures required to slowdown this newly evolving epidemic. The global prevalence of diabetes in 2010 was 284 million people worldwide constituting around 6.4% of the world population, which is higher than was projected in earlier studies. Furthermore, the projections for 2030 show the prevalence to reach 439 million individuals comprising ~7.7% of the world population. The burden of diabetes on the world economy has been rising steadily in the last decade to reach $376 billion in 2010 and is expected to reach $490 billion in 2030. Diabesity represents a substantial economic burden as reflected by diabetes and obesity consuming 14 and 5.7% of the USA’s total health expenditure, respectively, representing the highest known expenditure on diabesity worldwide. When costs associated with being overweight were also included, the upper limit of obesity expenditure rises to 9.1% of the USA’s total healthcare expenditure. The highest recorded expenditure on diabetes alone was in Saudi Arabia consuming 21% of the country’s total health expenditure, with no data available about the health expenditure on obesity. The health impact of diabesity is substantial to include long-term diabetic complications, reduction in health-related functioning, reduction of quality of life and reduced overall life expectancy. Long-term complications include myocardial infarction, cerebrovascular stroke and end-stage renal disease. Also recent advances have found that there is an association between chronic stress, depression and sleeping troubles to both diabetes and obesity. This century is the unprecedented diabetogenic era in human history. It is thus urgent to take steps including screening, prevention and early management in an attempt to control this evolving epidemic of diabesity.
