Do Women Live Longer or Do Men Die Earlier? Reflections on the Causes of Sex Differences in Life Expectancy

  title={Do Women Live Longer or Do Men Die Earlier? Reflections on the Causes of Sex Differences in Life Expectancy},
  author={Marc Luy and Katrin Gast},

Background: Although many different factors have been identified to contribute to excess male mortality, it is still unclear which path of the complex cause-effect chain is the decisive driver of the life expectancy gap between women and men. Objective: The question behind this study is whether these sex differences are caused primarily by factors leading to low female mortality or rather by factors causing high male mortality. We hypothesise that they are to a large extent caused by specific…

Patterns in age and cause of death contribution to the sex gap in life expectancy: a comparison among ten countries

Women live longer than men and the absolute difference between male and female mortality risk reaches its maximum at old ages. We decomposed the sex gap in life expectancy and investigated the

The impact of smoking on gender differences in life expectancy: more heterogeneous than often stated

Many populations have still remarkable potentials to further narrow their gender gaps in life expectancy, and over-generalized statements suggesting that smoking is the main driver of the gender gap in all populations can be misleading.

The impact of tobacco-related cancers on excess mortality rates in Polish men

Tobacco-related cancers significantly impact on life expectancy inequalities between females and males and significantly affect excess mortality rates in Polish men.

Sex gap in aging and longevity: can sex chromosomes play a role?

It is well known that women live longer than men, and recent data suggest that sex chromosomes may also contribute to the sex gap in aging/longevity through several potential mechanisms, including the unguarded X/Z, the toxic Y/W and the loss ofY/W.

Social differences in mortality and life expectancy in Germany. Current situation and trends

Social differences in mortality and life expectancy are a clear demonstration of the social and health-related inequalities that exist within a particular population. According to data from the

Probability of males to outlive females: an international comparison from 1751 to 2020

These findings challenge the general impression that ‘men do not live as long as women’ and reveal a more nuanced inequality in lifespans between females and males.

Sex Differences in Longevity and in Responses to Anti-Aging Interventions: A Mini-Review

It is shown that generalizations from one sex cannot be extended to the other, and inclusion of both sexes in biomedical studies of human or other animals is worth the effort and expense.

Male mortality rates mirror mortality rates of older females

The results support the hypothesis that men age faster than women while also suggesting that the difference is small and that from a practical standpoint male mortality rates behave similarly to the mortality rates of women approximately eight years their senior.

Gender-Specific Life Expectancy in Europe 1850–2010

It was not until the 1850s that the average life expectancy in women began to rise noticeably in Germany and Europe. Up to the 1980s it increased in waves. Since then the gender gap has gradually

Social Determinants of Remaining Life Expectancy at Age 60: A District-Level Analysis in Germany

Remaining life expectancy at age 60 (in short: RLE) is an important indicator of the health status of a population’s elders. Until now, RLE has not been thoroughly investigated at the district level

Although the female sex advantage in respect to most causes of death has been increasing, the differential for coronary heart disease has recently stabilized; and the lung cancer mortality rate among women is now increasing faster than that among men.

The life expectancy of nonsmoking men and women.

The results of the study suggest that the present longevity difference between men and women will disappear and actuarial tables should be divided by smoking behavior rather than sex to reflect this finding.

The life expectancy of nonsmoking men and women.

The pronounced difference in life expectancy between men and women in the United States and other industrialized countries has been attributed to a variety of causes, among them, differential rates

Why Do Females Live Longer Than Males?

Abstract In most countries, females live several years longer than males. Many biological and behavioral reasons have been presented in the scientific literature to explain this “female advantage.” A

Narrowing sex differentials in life expectancy in the industrialized world: early 1970's to early 1990's.

The results indicate that where some convergence has taken place, in relation to women, men have experienced more rapid gains in survival; the higher a nation's level of social and economic development, the greater the amount of convergence in male and female life expectancies.

Mortality pattern and life expectancy of Seventh-Day Adventists in the Netherlands.

Evidence was found for the thesis that abstinence from cigarette smoking is the main factor explaining the low mortality from ischaemic heart diseases among SDAs, while presumably an appropriate (prudent) diet confers additional benefit for example on colon cancer mortality.

The human male is, on most measures, more vulnerable than the female, and external maternal stress around the time of conception is associated with a reduction in the male to female sex ratio, suggesting that the male embryo is more vulnerable compared to the female.

Unusually small sex differentials in mortality of Israeli Jews: what does the structure of causes of death tell us?

The major types of behaviourally induced mortality are quantified to show that it is especially low among Israeli Jewish males, and mortality in certain subgroups of Israeli Jews is investigated to gain a better understanding of female mortality in this population.
