An international team of doctors and scientists is calling for more focus on the causes of death among young people around the world, age between 10 and 24, saying the issue is largely ignored by policy makers. A study published in the medical journal the Lancet found that 40% of adolescent deaths are caused by various forms of injury.
    Until this research was published there were little data on how many young people die worldwide in which countries and for what reasons. Now a pattern is emerging. The study suggests the death rate is strongly linked to how poor a country is. Most deaths are in the developing world driven by high rate of infectious disease and of maternal death rate. But globally 40% of adolescent deaths are caused by types of injury including road traffic accident, suicide and violent attacks.
