"Epidemiology of 'Prediabetes' and the MS - Global View"Prof. Jonathan Shaw (biography)
English - 2005-04-14 - 34 minutes
|
 | (27 slides) |
Summary :
The metabolic syndrome, diabetes and pre-diabetes have become major public health problems in recent decades, and are increasing in prevalence around the world. Declining levels of physical activity, increasing caloric intake and the subsequent rises in obesity rates have been documented in populations from virtually every ethnic and cultural background. Whilst pre-diabetes is more common in most populations than is diabetes itself, its rise in prevalence has not been as sharp, and there is somewhat less variability in its prevalence from one population to another. Nevertheless, it is estimated that the numbers of individuals worldwide with impaired glucose tolerance will rise from 314 million to 472 million in the next 20 years.
The epidemiology of the metabolic syndrome, particularly in terms of comparing data from one ethnic group to another, has been severely hampered for several reasons. Firstly, lack of agreement on a definition, and varying interpretation of the same definition has meant that the criteria used for diagnosis of the metabolic syndrome are rarely the same in any two different publications. Secondly, the published cut-points for some of the criteria, especially for obesity, have not, as yet, taken into account ethnic differences. Thus, for Asian populations, who usually have lower BMIs and waist circumferences than do Europids, but greater metabolic disturbance at any given level of obesity, metabolic syndrome definitions which use Europid obesity criteria seriously underestimate the scale of the problem.
Despite difficulties in determining accurate estimates of the prevalence of the metabolic syndrome, its serious implications in terms the risks of developing cardiovascular disease and diabetes have been consistently shown in a number of populations.
Learning objectives :
After viewing this presentation the participant will be able to discuss:
- Prevalence of pre diabetes worldwide
- Prevalence of the metabolic syndrome in consequence of the definition used
- The need to develop a uniform method of determining obesity criteria that is ethnic specific
