Why Do Women Live Longer Than Men

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 is the reason women live longer than men? Why the advantage has grown over time? The evidence is limited and we only have partial answers. We know that biological, behavioral and environmental factors all play a role in the fact that women have longer lives than men, however, ابر التخسيس we do not know how strong the relative contribution of each one of these factors is.

We have learned that women are living longer than males, regardless of weight. However it is not due to the fact that certain biological or non-biological factors have changed. What are these changing factors? Some are well known and relatively straightforward, like the fact that men smoke more often. There are others that are more intricate. For example, 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. As we can see, all countries are above the diagonal parity line - this means in all countries that a baby girl can be expected to live for longer than a new boy.1

It is interesting to note that the advantage of women exists in all countries, country-specific differences are huge. In Russia women live 10 years longer than males. In Bhutan the gap is just half a year.

In the richer countries, the longevity advantage for ابر التخسيس women was previously smaller.
Let's look at how the gender advantage in longevity has changed over time. The chart below illustrates the men and women's life expectancies at birth in the US in the years 1790-2014. Two distinct points stand out.

The first is that there is an upward trend. and women in the US are living much, much longer today than a century ago. This is in line with historical increases in life expectancy everywhere in the world.

Second, the gap is widening: While the advantage of women in terms of life expectancy was very small It has significantly increased over time.
