life expectancy has increased by six years in a generation research has shown.
Global life expectancy at birth rose by 5.8 years for men and 6.6 for women between 1990 and 2013.
But UK women saw only a 4.4-year increase from 78.4 to 82.8 years. In high-income regions, life expectancy had mostly been increased by falling cancer and heart disease death rates, said the report.
There have also been dramatic increases in life expectancy in some low-income countries, experts found. In Nepal, Rwanda, Ethiopia, Niger, the Maldives, Timor-Leste and Iran, life expectancy increased by more than 12 years in the last two decades
Southern Africa was the only region experiencing the opposite trend, due to the scourge of HIV and AIDS. Their lifespans have shortened by more than five years.
Certain causes of death were shown to have increased around the world since 1990. They included liver cancer, drug use conditions, chronic kidney disease, sickle cell disease, diabetes and pancreatic cancer, the study in The Lancet medical journal found.
