The researchers found the risk of death was 32 percent higher across a lifetime for single men compared to married men. Single women face a 23 percent higher mortality risk, compared to married women.
In real numbers, “under the worse-case scenario,” single men could die about eight to 17 years earlier than their married male friends, says Roelfs, citing that nearly all of the data was gleaned from studies conducted in the last 60 years. Women don’t fare much better. They could die seven to 15 years earlier than their married female counterparts.
The researchers speculate their longevity findings could be tied to poorer health benefits, meager public assistance and less income for singles. And some singles may not have the same social support that married couples have “by default,” explains Roelfs.
