Why do women live longer than men?

0

Everywhere in the world women live longer than men – but this was not always the case. The available data from rich countries shows that women didn’t live longer than men in the 19th century. What’s the reason women are more likely to live longer than men? Why the advantage has grown in the past? The evidence isn’t conclusive and we have only partial answers. Although we know that there are behavioral, biological, and environmental factors which play a significant role in women who live longer than males, we aren’t sure how much each one contributes.

1 year agoIt is known that women are living longer than men, regardless of their weight. But, this is not because of certain biological or non-biological factors have changed. These variables are evolving. Some are well known and relatively straightforward, like the fact that men smoke more often. Certain are more complicated. For example, تزويد متابعين تويتر (Read This method) there is evidence that in rich countries the female advantage increased in part because infectious diseases used to affect women disproportionately a century ago, so advances in medicine that reduced the long-term health burden from infectious diseases, especially for survivors, ended up raising women’s longevity disproportionately.

Everywhere in the world women tend to live longer than men

The first chart below shows life expectancy at birth for men and women. We can see that every country is above the diagonal parity line , this means in all countries that a baby girl can be expected to live for longer than a newborn boy.1

This chart illustrates that, although there is a women’s advantage throughout the world, the differences between countries can be significant. In Russia women have an average of 10 years more than men; in Bhutan the difference is just half a year.

In wealthy countries, the longevity advantage for women used to be smaller

Let’s examine how the female longevity advantage has changed in the course of time. The chart below shows male and female life expectancy at the birth in the US during the period 1790 to 2014. Two distinct features stand out.

First, there’s an upward trend. Men as well as women in the US live a lot, much longer today than a century ago. This is in line with historical increases in life expectancy everywhere in the world.

There is an ever-widening gap: female advantage in life expectancy used be very modest however it increased dramatically during the last century.
