Scientists have finally answered the question of why men, on average, do not live longer than women. According to a new study, men are more prone to heart disease than the “weaker sex”.
The study was led by University of Southern California, Davis School of Gerontology.
The researchers examined the life expectancy of people born between 1800 and 1935 and the scientific work included 13 nations. The study of mortality in adults over 40 years found that women born after 1880 have shorter lives in 70 percent of cases.
High blood pressure, high cholesterol and smoking are key risk factors for heart disease. Contrary to popular belief, smoking affects only 30 percent of the difference in mortality between women and men after 1890.
According to the researchers, the impact of heart disease in men (when they were in middle and advanced age) raises the question of whether men and women are subject to these different diseases in different periods of life.
– Further study could include analysis of diet and physical activity between countries, a deeper study of genetics and biological vulnerability of the terminals at the cellular level, as well as the relationship between these findings and brain health in later years – said William F. Kieschnick, professor of neurobiology of aging .
According to the study, there are significant differences in the length of life expectancy between the sexes after the twentieth century. It has been shown that the level of mortality declined after prevention of infectious diseases and more diet after 1800 and 1900. The study found that women began to “take advantage of longevity” much faster.
– We are surprised that the different mortality rates between women and men, from the period 1870 onwards. Sometimes life expectancy was 50 to 70 years and rarely exceeded eighty years of age. The twentieth century has certainly led to higher mortality rates among men – said Professor of Gerontology, Ellen Krimins the “Proceedings of the National Academy of Sciences’ publication.
In the United States approximately 610,000 people dies from heart disease every year. This means that this health problem affects one in four people. Heart disease is the leading cause of death for people of all ethnicities and both genders. More than half of the deaths resulting from heart disease in 2009 were male.
