A global study found that the risk of early death for men aged 50 years and over is 60% higher than for women of the same age group, partly due to higher rates of smoking and heart disease in men.
Is that the research published in the journal Canadian Medical Association Journal It was found that the gender mortality risk gap differs for different countries.
Differences between the sexes
“Many studies have examined the potential impact of social, behavioral and biological factors on gender differences in mortality, but few have investigated the potential difference across countries,” said Yu-Tzu Wu of King’s College London and Newcastle University in London.
The research examined various socio-economic factors, lifestyle, health and factors that may contribute to the death gap between men and women aged 50 and over.
The data included more than 179,000 people in 28 countries, and more than half – 55% – were women.
The influence of sex
“The effect of gender on mortality should not only affect the physiological difference between men and women, but also include the social structure of sex, which differs in different societies,” Wu said. In particular, a large difference across countries may mean a greater gender impact than gender. ”
“Although the biology of sexes is consistent across populations, variation in cultural, societal and historical contexts can lead to different life experiences for men and women and variation in the mortality gap across countries,” Wu added.
The researchers noted that the results are in agreement with the literature on life expectancy and mortality.
“The heterogeneity of gender differences in mortality across countries may indicate a significant influence of sex on healthy aging in addition to biological sex,” the study authors noted.
