In 2015, 50 million people died worldwide. But did you know that more than half of these deaths (about 25 million) were caused by the same ten diseases? A study by the World Health Organization ( WHO ) has revealed what we will die in fourteen years, in 2020, as well as the evolution of life expectancy worldwide.
In 2015, more than half of the deaths in the world were caused by the same ten diseases: coronary artery diseases (7.5 million), strokes (6.5 million), pneumonia (3 million), chronic obstructive pulmonary diseases ( 2 million), AIDS (2 million), diarrhea (1.5 million), lung cancer (1.5 million), diabetes (1 million), heart failure (1 million) and liver cirrhosis (1 million). The latest report of the World Health Organization reveals how these diseases will evolve in the next fourteen years, facing 2030, among many other interesting facts about the future of our health and our life expectancy.
The evolution of the most lethal diseases today
Diabetes is the disease that will experience the greatest increase: in 2030 it will cause 34% more deaths in the world. It is followed by lung cancer (24% more), chronic obstructive pulmonary diseases (20% more), pneumonia (13% more), heart failure (13% more), stroke (8 % more) and coronary artery diseases (3% more). On the other hand, three of these diseases that today are the most lethal will cause fewer deaths: it is liver cirrhosis (1% less), AIDS (5% less) and diarrhea (6% less) .
Diseases that will experience an increase in the number of deaths
Between this year and 2030 there are five diseases that will register a considerable increase in the number of deaths. This is prostate cancer, which will produce 38% more deaths than today, diabetes (34% more), bladder cancer (29% more), throat cancer (25 more) and mouth cancer (24% more).
Diseases that will see the number of deaths they cause reduced
On the opposite side, five other diseases will see how the number of deaths they cause worldwide per year is drastically reduced in 2030. We talk about tuberculosis (43% less), the Measles (42% less), malaria (31% less), parasitic diseases (23% less) and meningitis (20% less).
The deadliest diseases in 2030, by region
However, the diseases that cause the most deaths will vary depending on where we are in the world. Thus, in Europe the most lethal will be coronary artery diseases (1.9 million deaths), as in America (1.1 million deaths), Southeast Asia (2.5 million deaths) and the Middle East ( 780,000 deaths). On the other hand, in the Pacific region the most lethal disease will be strokes, and in Africa it will continue to be AIDS.
Coronary artery diseases: 1.9 million
Stroke: 1.2 million
Lung cancer: 440,000
Colon cancer: 300,000
Coronary artery diseases: 1.1 million
Chronic obstructive pulmonary diseases: 400,000
AIDS: 1.3 million
Pneumonia: 1.1 million
Coronary artery diseases: 630,000
In Southeast Asia
Coronary artery diseases: 2.5 million
Stroke: 2.3 million
Chronic obstructive pulmonary diseases: 2.1 million
In the Pacific region
Stroke: 3 million
Coronary artery diseases: 2.2 million
Chronic obstructive pulmonary diseases: 1.3 million
Lung cancer: 1.2 million
Liver cancer: 730,000
In the Middle East
Coronary artery diseases: 780,000
Chronic obstructive pulmonary diseases: 260,000
Increase in life expectancy throughout the world
As to how life expectancy will evolve from here to the next fourteen years, if in the year 2000 the life expectancy worldwide was 68 years and in 2015 it was 72, in 2030 this it would increase three more years, to 75. The country with the lowest life expectancy at the beginning of the century was Zimbabwe (39 years) and last year South Africa (50 years), while in 2030 it would be, always according to World Organization data of Health, Namibia (51 years old). On the opposite side of the coin, Japan will continue to be, as it has been in both 2000 and 2015, the country with the highest life expectancy with an impressive 88 years on average.
By regions, in North America life expectancy will increase two years, from the current 78 years to 80. In Central America and South America it will increase three years, from 75 to 78. In Europe, on the other hand, life expectancy will be it will increase in two years, from the 78 that are currently registered at 80. In North Africa it will increase from the current 76 years to 79, while in South Africa and Central Africa the greatest increase in life expectancy will be experienced: a total of 5 years, from the current 60 to 65. In the Middle East it will increase three years, from 76 to 79, and in Asia another three, if 75 to 78 years. In Southeast Asia it will go from the current 72 years to 76 thanks to an increase in life expectancy of four years, while in Australia it will go from the current 81 years to 84.
