New research finds U.S. men’s life expectancy is 6 years less than women’s—and why

Published November 18, 2023


Prevention quotes Thomas Russo in an article explaining new research finding why American women tend to live six years longer than American men. Russo explains there may be several explanations to this, although they are only hypotheses. “We know that the X chromosome is important for the immune response, and women have two of them—there’s a belief that women will have a better immune response when faced with an infection,” he says.
