The Economist has an article on Chronic diseases in developing countries.
" The World Health Organisation expects deaths from non-communicable diseases to rise by 15% between 2010 and 2020, with jumps of over 20% in Africa and South-East Asia. The number of Chinese diabetics is expected to double by 2025. Even in sub-Saharan Africa, chronic illnesses are likely to surpass maternal, child and infectious diseases as the biggest killer by 2030. Most of them stem from sugar, fat, smoke and sedentary lifestyles."
