S Korean women could hit 91 as life expectancy rises
LONDON: While most people born in rich countries will live longer by 2030 — with women in South Korea projected to reach nearly 91 — US citizens will continue to have one of the lowest life expectancies of any developed country, a new study predicts.
Scientists once thought an average life expectancy beyond 90 was impossible but medical advances combined with improved social programmes are continuing to break barriers, including in countries where many people already live well into old age, according to the study’s lead researcher, Majid Ezzati of Imperial College, London. “I can imagine that there is a limit, but we are still very far from it,” he said.
Mr Ezzati estimated that people would eventually survive on average to at least 110 or 120 years. The longevity of South Korean women estimated in 2030 is largely because of investments in universal healthcare, he said. South Korea also led the list for men. “It’s basically the opposite of what we’re doing in the West, where there’s a lot of austerity and inequality,” he said.
Mr Ezzati and his co-authors used death and longevity trends to estimate life expectancy in 35 developed countries. The calculation is for a baby born in 2030.
The study was published online on Tuesday in The Lancet journal.
Women were ahead of men in all countries.
Behind South Korea, women in France, Japan, Spain and Switzerland were projected to live until 88.
For South Korean men, life expectancy is expected to reach 84.
Next were Australia, Switzerland, Canada and the Netherlands at nearly 84.
At the bottom of the list: Macedonia for women at nearly 78 and Serbia for men at about 73. While some genetic factors might explain the longevity in certain countries, social and environmental factors were probably more important, Mr Ezzati said.
The study estimated that the US, which already lags behind other developed countries, will fall even further behind by 2030, when men and women are projected to live to 80 and 83.
US women will fall to 27th out of 35 countries, from their current ranking of 25, and men will fall from 23rd to 26th.
The researchers note that among rich countries, the US has the highest maternal and child death rates, homicide rate and is the only high-income country without comprehensive healthcare.
