Study Claims Childless People Die Sooner

A recent study from Denmark has linked childlessness with higher death rates and instance of mental illness.

Researchers found that death rates were two to four times higher among childless couples treated for infertility—regardless of age, education, income, health, and lifestyle.

They also found that adoption tended to increase longevity and lower the risk of mental illness by half.

“This study finds that [becoming parents] decreased rate of death,” the study’s authors wrote. Noting that this association is not the root cause of death, researchers also said that, “Our results suggest that the mortality rates are higher in the childless.”

Study researchers examined information on more than 21,000 childless couples in Denmark who underwent assisted reproductive procedures (i.e., in-vitro fertilization or IVF) between 1994 and 2005. During this same time period the following occurred within the group:

  • Approximately 15,000 children were conceived
  • More than 700 women and 550 men were diagnosed with a mental illness
  • Early death rates from cancer, circulatory disease, and accidental death were four times higher among childless women than women and twice as high for childless men
  • Two hundred men and nearly 100 women died

Interestingly, the study also looked at the impact of adoption on those parents unable to conceive and found that early death rates were cut in half among women and men who adopted children (about 1,600 couples in the study adopted children), and instances of mental illness were decreased by half among couples that adopted a child.
