Rapid Response:

Advancing age due to increased life expectancy itself is a risk factor in causation and mortality of Non-communicable diseases

As infectious diseases are getting under control due to awareness, hygiene, clean water, improved sanitation, etc., mortality has decreased due to them and life expectancy has increased. The non-communicable diseases like diabetes type 2, hypertension, cancer are the diseases the incidences of which increase as age advances, i.e. with increase in life expectancy. Since life expectancy has increased by an average of 10 years from 1980 to 2015, quite evidently the non-communicable diseases have also increased and the mortality due to these has increased as well. This does not mean that other risk factors like unhealthy diet and sedentary life styles are not implicated in their causation. Besides these risk factors, increased life expectancy itself causes these non-communicable diseases which are rife all over the world presently.
