‘World Health Day’ is celebrated every year on April 7, the day ‘World Health Organization (WHO)’ was founded in 1948.

Each year, on this day, people from all walks of life across the globe are invited by WHO to focus on a particular emerging health challenge of global relevance, which becomes the theme of the ‘World Health Day’ for the year.

In 2012, the theme for this day was, “Aging and health: Good health adds life to years”. It focuses on how good health throughout the life span can help the senior citizens to lead a full and productive life and in turn makes them valuable and experienced resources not just to their respective families, but also to the societies and communities they belong to.

Aging affects all:

The process of aging, without any exception, affects the entire population, young or old, male or female, rich or poor, alike, across the world and is considered as one of the key factors of social transformations through the passage of time.

With the advancement in medical science coupled with increasing social awareness for living a healthy life, the average life expectancy of the population in the 20th century reportedly increased by around 30 years in the developed world and is expected to maintain similar growth trend in the 21st century, as well.

Now, with an increasing life expectancy even in the developing world, the issue is assuming greater magnitude and at a much faster pace.

In the language of Steve Jobs:

Steve Jobs, the global icon and the former CEO of Apple Inc., during his commencement speech to Stanford in 2005, very aptly articulated as follows:

“No one wants to die. Even people who want to go to heaven don’t want to die to get there. And yet death is the destination we all share. No one has ever escaped it. And that is, as it should be, because Death is very likely the single best invention of Life. It is Life’s change agent. It clears out the old to make way for the new. Right now the new is you, but someday not too long from now, you will gradually become the old and be cleared away. Sorry to be so dramatic, but it is quite true.”

In a normal situation old age precedes death and just like the inevitability of death, everybody, even a baby born today will need to embrace the old age before being cleared away by death. Thus, as the population will age as a natural process, there will be growing need to make even the old age more meaningful. Sounds like a tall call, but quite pertinent indeed.

Although, an average elderly person of today is much healthier than of the past generations, they will still need appropriate health management and social security plans, especially for an emerging economy, like India.

World population aging faster:

Population Division of the Department of Economic and Social Affairs of the United Nations in its publication titled, “World Population Aging:  1950-2050”, described the trend of ageing of the global population and highlighted the following:

• Population aging is unprecedented : This is unparallel in human history and the current century will witness even more rapid aging than the previous one.
• Population aging is pervasive:  It is affecting every man, woman and child across the world, though currently it is at different stages of progress in different countries.
• Population aging is enduring:  The world will not return to the young populations of our ancestors.
• Population aging has profound implications:  It affects many facets of lives of human beings.

Increasing burden of disease:

The burden of some serious age related diseases increases by manifold as the life progresses towards its ‘twilight zone’. Even now, the treatment costs and overall burden of age related diseases, both in the developed and the developing countries, are escalating in an alarming proportion.

Age related diseases:

According WHO, in the industrialized countries over 75 percent of deaths in people of over 65 years of age are due to cancer, cardiovascular and cerebrovascular diseases, in addition to disabilities like, loss of bone density leading to osteoporosis.

As per published reports, the incidence of age related Alzheimer’s disease, which is now incurable, will almost double every 20 years to reach around 66 million in 2030 and over 115 million in 2050.

Research for delaying the onset:

Reuters in an article titled, “Is aging a disease?” published in May 20, 2010 reported that many scientists from various parts of the world are now studying the genetic mechanisms of the old persons to help delay, if not overcome, the onset of diseases like Alzheimer’s, cancers, diabetes, cardiovascular ailments and many other age-related illnesses to help leading a better quality of life during old age of the human population.

Elderly population and the impact:

As per an estimate of the United Nations (UN), there will be around 1200 million people over 65 years of age by 2025. Currently, from across the world millions of aging people are denied of proper health care for various reasons. The situation in India is much worse.

It is envisaged by many that failure, either on the part of the Government or society at large, to address this critical issue today, could have a snowballing effect tomorrow.

In Japan, currently half of the national health budget is spent on the elderly individuals, which constitute around a whopping 23 percent of the country’s population. According to another estimate of the Japanese Government, by 2055 half of their total population will constitute of retired senior citizens.

India:

With over 65 percent of the population of India being now below 30 years of age, the country is  well poised to have one of the largest numbers of young and productive population in the world, though 7 percent of country’s 1.13 billion people are now over 60 years of age and the number is growing.

The Median Age of the population will keep on increasing over a period of time as follows:

Aging Profile: India and other countries

Year	2000	2015	2025	2030	2035	2040	2050
Median Age–India	23.4	27.2	30.3	31.4	33.5	35.0	37.9
Median Age–World	26.4	29.5	31.9	33.0	34.0	34.9	36.8
Median Age–More Developed Regions	37.3	41.2	43.3	44.2	45.0	45.4	45.2
Median Age–Less Developed Regions	24.1	27.5	30.0	31.2	32.4	33.5	35.7
Median Age–Least Developed Regions	18.1	19.6	21.2	22.2	23.3	24.5	27.1

Growth of elderly population is much faster than the population:

As as per the paper titled, “Implications of an Aging Population in India: Challenges and Opportunities” presented at ‘The Living to 100 and Beyond Symposium’ of the Society of Actuaries in Orlando on January 12–14, 2005, the Indian population has approximately tripled during the last 50 years, but the number of elderly Indians has increased more than fourfold.

Assuming continuation of this trend, the United Nations have predicted that the Indian population will again grow by 50 percent in the next 50 years, with the elderly population recording another fourfold growth.

Changing demographic profile:

The situation in India, therefore, by no means is a trivial one and needs to be addressed with a right earnest and sooner, mainly because of the changes in the demographic profile of the country, as follows:

Projected Changes in Indian Demography (in Million)

Age Group	2000	2015	2025	2030	2035	2040	2050
0-14 Years	347	345	337	327	313	300	285
15-59 Years	593	782	865	895	919	937	938
>60 Years	77	119	167	195	223	248	308
Total	1,017	1,246	1,369	1,417	1,455	1,485	1,531

Thus, over a period of time in India, increasing number of less productive elderly people and the declining trend of the younger population, could adversely impact the overall socioeconomic profile and and the disease burden of the nation.

Conclusion:

In India, there has been hardly any support in terms of social security, especially for a vast majority of people, who are unable to work after becoming senior citizens of the country.

In a situation like this, the Government of India, civil society and the private sector enterprises of the country should work in tandem to give shape to appropriate policy measures to effectively address the issues of the increasing number aging population of the country, over a period of time.

This is necessary not just for the socioeconomic reasons, but also to arrest any significant increase in the overall disease burden of the nation with its possible adverse impact on the growing economy of the country.

Continuing lack of interest to work out a long term social and policy measures to address the important issues related to population aging in India, in a holistic way, could significantly impede the pace of economic growth of the country, celebration of the ‘World Health Day’ on April 7, 2012 notwithstanding.
