Thanks to disease prevention and medical advancements, global life expectancy increases by about six years. According to a study published in the British journal 'Lancet', the average life expectancy went up to 71.5 years in 2013 from 65.3 years in 1990.
The report suggests that India has made good progress. In India, the life expectancy in men has gone up by 7 years and in women it's gone up by almost a decade. The country has been able to curb child and adult mortality. The increase has come despite the rising cases of liver disease and deaths caused by chronic kidney disease.
Global life expectancy rose by 5.8 years in men and 6.6 years in women between 1990 and 2013. The rise in global life expectancy can be attributed to the decrease in death rates of cancer and cardiovascular disease in the high-income countries. In less affluent regions, there was a decline in death rates against diarrhoea, lower respiratory tract infections and neonatal disorders.
According to lead author Dr. Christopher Murray, professor of Global Health at the University of Washington, "The progress we are seeing against a variety of illnesses and injuries is good, even remarkable, but we can and must do even better."
