Longevity studies reveal gender life expectancy gaps and biological aging peaks

In Brazil, men live an average of 6.6 years less than women. According to IBGE data for 2024, life expectancy at birth is 73.3 years for men compared to 79.9 years for women. The MAG Longevity Institute attributes this gap to a lower tendency among men to seek preventive healthcare, often delaying medical consultations and exams until symptoms appear.

Data from the Ministry of Health indicates that the risk of death from non-communicable chronic diseases is 40% to 50% higher in men than in women. Experts suggest this disparity is driven by lifestyle habits, risk exposure, and cultural factors rather than purely biological ones.

Separately, research published in the journal Nature Aging has identified two distinct peaks of accelerated biological aging in the human body, typically occurring around ages 30 and 50. By analyzing tissue samples from nearly 1,000 individuals, researchers found that different organs possess unique ‘biological clocks.’ For instance, arteries show rapid changes around age 30, while ovaries experience intense shifts between ages 35–40 and 55–60. These processes are linked to reduced energy production, increased inflammation, and diminished cellular repair capabilities.
