Death risk for men 60% higher than for women in 28 countries

In a new study, researchers found men aged 50 and over had a 60% greater risk of death than women, partly explained by heavier rates of smoking and heart disease in men.

The research was conducted by a team at King’s College London and elsewhere.

Many studies have examined the potential impact of social, behavioral and biological factors on sex differences in mortality, but few have been able to investigate potential variation across countries.

Different cultural traditions, historical contexts, and economic and societal development may influence gender experiences in different countries, and thus variably affect the health status of men and women.

In the study, the team examined different socioeconomic (education, wealth), lifestyle (smoking, alcohol consumption), health (heart diseases, diabetes, hypertension and depression) and social (spouse, living alone) factors that might contribute to the mortality gap between men and women aged 50 and older.

The data included more than 179,000 people across 28 countries and more than half (55%) were women.

The team says the effects of sex on mortality should include not only physiologic variation between men and women but also the social construct of gender, which differs across societies.

In particular, the large variation across countries may imply a greater effect of gender than sex.

Although the biology of the sexes is consistent across populations, variation in cultural, societal and historical contexts can lead to different life experiences of men and women and variation in the mortality gap across countries.

The findings are consistent with the literature on life expectancy and death rates.

The researchers recommend that public health policies should account for sex- and gender-based differences and the influence of social and cultural factors on health.

One author of the study is Dr. Yu-Tzu Wu.

The study is published in Canadian Medical Association Journal.
