Women live longer than men because they are less prone to heart disease and smoking-related illnesses due to modern lifestyles, rather than any biological difference, a new study has found.

Researchers found that heart disease was responsible for as much as 40% of the ratio increase in male to female mortality, while smoking contributed about 30% of the increase.

Diet is a major factor in developing heart disease, with the World Heart Federation estimating that a high-saturated fat diet causes 31% of coronary heart disease and 11% of strokes worldwide.

The study used data from more than 1,700 birth cohorts across a 135-year-period from 1800 to 1935 and looked at 13 developed countries, including England, France, Italy and Spain.

Today, women can expect to live longer than men in every country in the world. According to UN data from 2013, the global average life expectancy was almost 4 ½ years longer for women at 71 years compared to men at 66.5 years.

However, the research suggests this gap was not always the case, but that the phenomenon of excess adult male mortality - men having generally shorter lifespans than women - emerged at the start of the 20th century.

"It is common belief that women have always lived longer than men, which basically means that men have higher mortality than women, but what we found is that this trend of women outliving men for a large number of years is actually a fairly recent phenomenon," says Dr Hiram Beltrán-Sánchez, the study's leading author, told Newsweek.
