A three-year analysis, carried by The World Health Organization, shows that instead of genetics, social factors play a more vital role in huge variations in ill health and life expectancy all around the globe.

The report suggests “People are being killed by social injustice on a grand scale.” For example, if a boy lives in some deprived suburb, he may live average 28 years less than a boy who born in an affluent area.

The average life expectancy in Hampstead (A wealthy area in London) is 11 years longer than in nearby St Pancras.

The research also explains that a girl in some poor African country may live average 42 years less than a girl in Japan.

In Sweden, only one woman dies during pregnancy out of 17,400 while in Afghanistan the chances are one out of eight.

The report has been drawn up by a renowned panel of experts t who form the WHO’ Commission on the Social Determinants of Health .the report concludes that in almost every country, poor socioeconomic circumstances are causing poor health.

These differences have been indicated so that they can’t be explained by genetics or biology.

The authors of the report say: “A combination of bad polices, politics and economics is responsible for the fact that a large number of people in the world enjoying the good health that is possible biologically.”
