Greater expectations, greater burden: Men now live till 63.2 yrs, women reach 67.5 -Kounteya Sinha

An average Indian man's life expectancy (LE) at birth has increased by nearly 15 years in the last 40 years, while an average Indian woman is living over 18 years longer than what she did four decades ago.

The world population's life span has gained more than a decade since 1970 - from 56.4 years in 1970 to 67.5 years in 2010 for an average male and from 61.2 years to 73.3 years for a woman.

An average Indian man and woman's LE is 63.2 years and 67.5 years, respectively.

An average Chinese male is living for 72.9 years almost 10 years longer than an Indian male and a Chinese woman is living 11.5 years longer than her Indian counterpart.

An average American is living nearly 13 years longer than an Indian.

The world's largest study on LE in 187 countries for each decade from 1970 to 2010 published by the British medical journal the Lancet shows that globally from 1970 to 2010 male LE at birth increased by 11.1 years and that of female rose by 12.1 years.

The greater increase in female LE widened the gap between the genders from 4.8 years in 1970 to 5.7 years in 2010.

Speaking to TOI from London, study author professor Majid Ezzati of Imperial College, London, and associate professor of the Institute for Health Metrics and Evaluation (IHME) at the University of Washington, said, "One of the main reasons behind India's impressive gain in LE has been the reduction in numbers of child mortality and low mortality among young adults. The US and several other countries have taken decades to improve LE. If India manages to cut down its tobacco consumption, lower high blood pressure rates in its population and increase physical activity thereby cutting down obesity rates, increase in LE of an average India will increase faster."

According to the study, global LE increased about three-four years per decade for both genders in every decade apart from the 1990s, when smaller improvements were recorded 1.4 years for male LE and 1.6 years for female LE largely because of the effect of HIV/AIDS in some regions and deaths related to alcohol in eastern Europe and central Asia coupled with a slowdown in survival gains in childhood.

The LE of a Pakistani man has increased by 11.5 years (52.4 in 1970 to 63.9 years in 2010) and that of a woman increased by almost 16.7 years during the same period (51.1 in 1970 to 67.8 years in 2010). LE in Bangladesh has jumped by leaps and bounds over the last 40 years.

An average Bangladeshi is living till 67.2 years - a rise by almost 25 years and in case of a Bangladeshi woman, the life span has increased by 23.5 years (47.5 years in 1970 to 71 years in 2010).

In 2010, Japanese women had the highest LE at birth in the world at 85.9 years, while Iceland had the highest LE for men at 80 years.

Haiti had the lowest life expectancy at birth in 2010 for both men and women 32.5 and 43.6, respectively largely due to the disastrous earthquake in January, 2010.

The largest overall gain in life expectancy since 1970 was in the Maldives, which saw an increase in male LE of 54.4% since 1970 from 50.2 to 77.5 and a 57.6% increase in women's LE from 51 in 1970 to 80.4 in 2010.

Other countries that experienced gains in LE greater than 20 years since 1970 were Bhutan, Iran and Peru.

An average man in the US lived for as long as 75.9 years, the UK (77.8 years), Switzerland (79.7 years), Germany and France (77.5 years), Sri Lanka (71.6 years) and Australia (79.2 years).

The Lancet study said, "Global LE has increased substantially in the past 40 years for men and women, despite major global and regional health crises. This increase has been driven by large declines - by almost 60% in child mortality, declines of 40% or more in adult female mortality and declines of 15%-35% for adult male mortality."

Global population rose from 3.7 billion in 1970 to 6.9 billion in 2010, combined with a growth in the average age of the population, has led to an increase in the number of deaths to 52.8 million in 2010 from 43.3 million in 1970. In this period, the global crude death rate declined from 11.7 per 1,000 individuals to 7.7 per 1000 individuals because of the large (86.7%) relative increase in world population. Under-five deaths decreased by more than half from 16.4 million in 1970 to 11.6 million in 1990 to 6.8 million in 2010. Deaths at ages older than 80 years increased from 3.8 million in 1970 to 12.1 million in 2010 (an increase of 215.6%).

According to assistant professor Haidong Wang from IHME and one of the study authors, "Because more children are now surviving to adulthood compared to earlier decades, health policy makers globally will need to pay much more attention to preventing deaths in young adults, aged 15-49, in coming years."

The study also shows the estimated distribution of deaths by age group for 2010. At the global level, 42.8% of deaths occur after individuals reach 70 years, and almost a quarter (22.9%) occurs in individuals older than 80 years.

At the other end of the age spectrum, deaths in children younger than five years accounted for 13% of all mortalities in 2010 down from 24.9% in 1990.
