Non-communicable diseases account for the majority of deaths worldwide
NON-COMMUNICABLE diseases (NCDs) such as cardiovascular diseases and cancer are the biggest killers on the planet, accounting for 63% of the 56m deaths in 2008. Such is their growing impact that the UN General Assembly is holding a two-day summit in New York this week to address their prevention and treatment. This is only the second time in history that the UN has convened on the topic of health (the first was to discuss AIDS). NCDs have long been considered a rich-world problem, but current figures show their increasing prevalency in developing countries. Indeed, of the 36m people killed by NCDs, some 80% live in low- and middle-income countries. These diseases are associated with increased prosperity and longevity, and the results are costly. The World Economic Forum estimates that NCDs will cost low- and middle-income countries $7 trillion over the next 15 years.
