The average life expectancy worldwide has increased about 22 years since 1950

average life expectancy
The average life expectancy worldwide has increased: In terms of average life expectancy worldwide, between 1950 and 2017. it increased from 48.1 to 70.5 years for men and from 52.9 to 75.6 years for women.
Almost half of the countries in the world are facing shortages of medical and hospital staff. World fertility declines gradually after 1950. Only four risk factors (hypertension, smoking, diabetes, obesity) account for half of deaths worldwide in 2017. The average life expectancy worldwide has increased dramatically by approximately 22 years between 1950-2017.

The average life expectancy worldwide has increased about 22 years since 1950

These are the four main findings of the new major international scientific study Global Burden Disease, which assesses the state of health of the world each year and presented in seven individual publications in The Lancet Medical Journal, led by Professor Christopher , director of the Institute of Health Measurement and Evaluation at the University of Washington in Seattle.

Global fertility

Global fertility, according to the “total fertility rate“, which shows the average number of children a woman will have over her life, declines after 1950. In 2017 91 countries had a birth rate of less than two, which is means that their population size is impossible to maintain. Between 2010-2017 33 countries had a declining population, including Greece, Portugal, Spain, Romania, Poland, Georgia, Japan and Cuba.

Negative world champion was Cyprus last year, with an average birth of only one child per woman, while in Greece the birth rate is 1.4 children per woman. On the other hand, in 104 countries, fertility increases over time, as does their population, with a birth champion in the African country of Niger, where a woman has on average seven children. Chad (6.7), Somalia (6.1), Mali (six) and Afghanistan (six) followed.

Researchers estimate that there is at least 30 doctors, 100 nurses and five pharmacists for every 10,000 residents in order for a country to be able to provide adequate health care to the population. In 2017, only 41 countries exceeded this threshold for medical staff and only 28 countries for hospital staff.

Almost half of the countries (92 out of 195 or 47.2%) have less than ten physicians per 10,000 population, while 46.2% (90 countries) have fewer than 30 nurses per 10,000 population. Benin is rated zero in sub-Saharan Africa. On the other hand, 15 countries are “excellent” in terms of staffing by medical and hospital staff: Norway, Sweden, Switzerland, Finland, Iceland, Denmark, Belgium, New Zealand, Germany, Austria, Bermuda, Czech Republic, Czech Republic, Czech Republic Slovakia.

The report also notes that deaths from war conflicts and terrorist attacks increased significantly by 118% between 2007 and 2017, with the opioid dependency epidemic worsening, with at least four million new cases and approximately 110,000 deaths last year (increase 75 % from 2007).

51.5% of all 2017 deaths worldwide (28.8 million deaths out of 55.9 million in total) were caused by only four risk factors that could have been avoided with appropriate lifestyle changes. Specifically, 10.4 million deaths were associated with high blood pressure (hypertension), 7.1 million with smoking, 6.5 million with high blood sugar (diabetes), and 4.7 million with high body mass index (obesity).

Non-communicable diseases

Non-communicable diseases were the cause of most deaths in 2017 (41.1 million or 73.4% of the total), with their share increasing by almost 23% between 2007-2017. Most deaths were cardiovascular (17.8 million) followed by cancers (9.6 million) and chronic respiratory diseases (3.9 million). Men are more likely to die from these causes than women.

Obesity and type 2 diabetes rates are on the rise in almost all countries, with the top three causes of motor problems and disability in 2017 being waist aches, headaches and depression disorders. Suicide rates among men (13.8 per 100,000 people) far outstrip those of women (four suicides per 100,000).

Also, between 1990-2017 there was a 71% increase in drug use disorders, 115% in Alzheimer’s and other dementia cases, 117% in diabetes cases, 80% in age-related hearing loss, 75% in back pain (waist pain). ) and 53% in cases of diagnosed depression disorders.

In terms of average life expectancy worldwide, between 1950 and 2017, it increased from 48.1 to 70.5 years for men and from 52.9 to 75.6 years for women. Women live longer than men almost anywhere in the world (in 180 out of 195 countries), from 1.4 years (Algeria) to 11.9 years (Ukraine), but they usually live longer years of poor health than men. men in old age. Singapore (74.2 years), Japan (73.1) and Spain (72.1) have the highest life expectancy, while the Central African Republic (44.8 years) has the smallest.

In Greece, life expectancy at birth is 83.6 years for women and 78.4 years for men (difference of 5.2 years). At the age of 60, one Greek woman has an expectation of another 25.7 years of life, while one man has another 22.1 years (3.6 years difference).

The world population has grown by 197%, almost triple, from 2.6 billion in 1950 to 7.6 billion in 2017. The average annual population growth between 2007-2017 was 87.2 million, against an increase of 81.5 million between 1997-2007.

In 1950 high-income developed countries made up 24% of the world population, but in 2017 only 14%. The countries with the largest population last year were China (1.41 billion), India (1.38 billion) and the US (324.84 million).
