Chronic non-communicable diseases are indeed becoming a global epidemic. In countries with high rates of HIV/AIDS such as South Africa, where being skinny is associated with disease/illness (not surprisingly, with the HIV/AIDS prevalence there), younger people are picking up more and more bad habits leading to obesity, diabetes, and cardiovascular disease. This is similar to an article I read the other day in the Nov. 2007 issue of the Journal of the American Dietetic Association: "Relationship between Food Insecurity and Body Composition in Ugandans Living in Urban Kampala." Uganda, the country where nearly 50% of the population under 5 is stunted due to undernutrition. What a paradox.
