Gender Hole in Life Expectancy Persists
MONDAY, Nov. 21, 2016 (HealthDay Information) -- Individuals are dwelling longer than ever, however males nonetheless path girls in life expectancy, a brand new examine exhibits.
A world staff of researchers reviewed knowledge from greater than 1 million folks worldwide. From the 18th century to the current, they discovered the previous few generations have had the most important life expectancy enhance within the historical past of people and all different primates.
For instance, life expectancy in Sweden over the past 200 years elevated from the mid-30s to over 80.
"We have made an even bigger journey in lengthening our lifespan over the previous few hundred years than we did over thousands and thousands of years of evolutionary historical past," examine co-author Susan Alberts, a biology professor at Duke College in Durham, N.C., mentioned in a faculty information launch.
However regardless of the general growing life expectancy -- the results of advances in medication and public well being -- males nonetheless are inclined to have shorter lives than females, one thing that's true in different primates as properly.
"The male drawback has deep evolutionary roots," Alberts mentioned.
"It is puzzling," she mentioned. "If we will make life final so lengthy, why cannot we shrink the male-female hole?"
Doable causes embody genetics and better ranges of dangerous behaviors in males, the researchers steered.
The examine was revealed on-line Nov. 21 within the journal Proceedings of the Nationwide Academy of Sciences.
