The World Health Organization says lifestyle factors are at the root of the non-communicable disease crisis, which is responsible for millions of premature deaths every year. WHO is calling for global action to combat this epidemic.
The World Health Organization breaks a common misperception. It says non-communicable diseases or NCDs do not mainly afflict affluent people. On the contrary, it says 80 percent of all NCDs occur in lowand middle-income countries.
WHO says non-communicable diseases are preventable. It reports up to 80 percent of heart disease, stroke, and type 2 diabetes and more than one-third of cancers could be prevented by eliminating the major risk factors. These include tobacco use, unhealthy diet, physical inactivity and the harmful use of alcohol.
