Men still aren’t living as long as women — and that holds true for humans’ primate cousins as well, a new study shows.

In the study, researchers looked at data from six populations of humans from both modern and historical times, in different countries. The investigators found that, “in spite of the huge gains in human longevity over the past century, the male-female difference has not shrunk,” said Susan Alberts, a professor of biology at Duke University and a co-author of the new study.

The researchers did find that the the amount by which women outlived men varied across populations. For instance, the largest male-female difference in life span among the populations studied was in modern-day Russia, where the gap is approximately 10 years. Much smaller differences were found in other populations such as people living in modern-day Nigeria and India.  Read more…
