The world’s population has crossed 8 billion, will this increase the burden on the healthcare system?

According to UN (United Nations) estimates, in 2023 India will have the most population The country is expected to overtake China. While the world population took 12 years to grow from 7 to 8 billion, it will take about 15 years to reach 9 billion by 2037, indicating that the overall growth rate of the population is slowing. The two most populous regions of the world in 2022 were both in Asia: Central and South Asia had a population of 2.1 billion while East and South-East Asia had a population of 2.3 billion. With a population of about 1.4 billion, China and India are the major contributors to population growth in these two regions.

Experts have expressed concern over the increasing pressure on the health sector due to the increasing population around the world. Dr Ishwar Gilada, Consultant on HIV and Infectious Diseases, told News 9, “The latest Global Population Report shows that the percentage of aged population is increasing as compared to previous years. This also indicates that a large number of people will suffer from diseases of old age such as high blood pressure and cancer.

He said that cancer is a matter of concern all over the world. Cancer incidence rates also increase with age, 25 cases per 100,000 people in the age group of 20 years, 350 cases per 100,000 people in the age group 45-49 years, 60 years and above It has more than 1,000 cases per 1,00,000 people of older age.

Delhi-based Senior Consultant Neuro-Psychiatry Dr Sanjay Chugh pointed out that the aging global population is also a major problem now as at least 25 per cent to 35 per cent of the aged population will experience or suffer from psychological depression. He said, “Diseases such as Alzheimer’s, major depression and anxiety disorders are most common in this population. It has also been observed that the population above 85 years of age has a higher tendency to commit suicide as compared to the youth.

increase in global average age

In addition, as the number of older people increases, the global average age (the age at which the population is divided into two equal parts) increases with each billion people. The average age of the world population in 1974 was 20.6 years, which means that half of the population was under 22.2 years of age and the other half was over this age. The current average age worldwide is 30.5 years.

Dr. Gilada said, “Along with cancer, this population will also be vulnerable to many other diseases and will be forced to live a compromised lifestyle. Global warming, air pollution and lifestyle related diseases will increase.” While Dr Chugh says, “The elderly population is also vulnerable to sleep disorders, cognitive decline and depression.”

health care burden

Consultant and Head of Critical Care at SL Raheja Hospital, Dr. Sanjith Sasidharan said that if a large proportion of the population is elderly, then the burden on healthcare can increase. He said, “At present, 80 per cent of patients in hospitals are above 45 years of age. The elderly population is 2 to 3 times more likely to be hospitalized than the younger population.”

The expert further added, “Already the nurse-patient ratio is 1:20, with the rise of a vulnerable population (elderly population), this ratio could go up to 1:30 or even 1:40. This will not only be a burden on healthcare but also an economic burden. The longer the patient stays in the hospital, which is the case with most elderly populations, the greater the financial burden.

However, when asked whether the advanced technology used in the healthcare sector will bring any relief, Dr. Sasidharan said, “Advance technology has been a great help, but it is a big help due to the increasing number of diseases in India and the burden on healthcare Can’t keep pace with.”

Dr. Chugh said, “The elderly population has very little access to medical treatment. Medical insurance does not cover the elderly population in most countries of the world. The way the world is moving towards longer life expectancy, it is not a good situation. There is a need to bring changes at the grassroots level to strengthen our healthcare system.”

global population

According to UN estimates, the world’s population reached 8 billion on Tuesday, which is half of what it was 4 billion at 48 years ago. Demographic data from the United Nations show that the world’s population will continue to grow over the next few decades, although this growth is mainly driven by a decrease in death rates and an increase in the average age of people.

According to UN population projection data and many experts, the world population will stop growing after reaching 8 billion, and it will reach 10 billion by the year 2100. In this century the population will be at its peak and then it will start decreasing. In 2086, it will peak with 10.4 billion people on the planet.
