Women live longer than men.

Area of Science:

• Gerontology
• Public Health
• Sociology

Background:

• A significant global gender gap in life expectancy (LE) exists, with women typically living longer than men.
• This disparity has been a long-standing subject of scientific inquiry, prompting research into its underlying causes and implications.
• Understanding geographic and socio-economic variations in this gap is crucial for aging research and public health strategies.

Purpose of the Study:

• To analyze geographic differences in the gender gap in life expectancy.
• To identify the primary factors contributing to the gender gap in life expectancy.
• To explore the role of socio-economic and environmental factors in shaping longevity differences between sexes.

Main Methods:

• Comparative analysis of life expectancy data across different countries and socio-economic contexts.
• Examination of epidemiological data, particularly focusing on cardiovascular disease (CVD) morbidity and mortality rates in men versus women.
• Review of trends in established democracies and countries with former Soviet influence.

Main Results:

• In developed nations, women live 4-7 years longer, primarily due to higher male cardiovascular disease (CVD) rates.
• The gender gap in LE is decreasing in European democracies, with projections suggesting parity by 2050 in Scandinavia.
• Conversely, the gap is widening in former Soviet bloc countries, reaching up to 13 years, indicating significant environmental influences.

Conclusions:

• Socio-economic factors and environmental influences play a critical role in determining the gender gap in life expectancy.
• While hormonal and genetic factors contribute, societal conditions significantly impact longevity differences between men and women.
• The diverging trends underscore the need for targeted public health interventions tailored to specific socio-economic and environmental contexts.
