People Who Care for Others Live Longer

Older people who help and support others are also doing themselves a favor, according to a new study.

An international research team has found that grandparents who care for their grandchildren on average live longer than grandparents who do not.

For the study, researchers conducted survival analyses of more than 500 people between the ages of 70 and 103, drawing on data from the Berlin Aging Study collected between 1990 and 2009.

In contrast to most previous studies on the topic, the researchers deliberately did not include grandparents who were primary or custodial caregivers. Instead, they compared grandparents who provided occasional childcare with grandparents who did not, as well as with older adults who did not have children or grandchildren, but who provided care for others in their social network.

The results of the analyses show that this kind of caregiving can have a positive effect on the mortality of the caregivers.

Half of the grandparents who took care of their grandchildren were still alive about 10 years after the first interview in 1990, according to the study’s findings.

The same applied to participants who did not have grandchildren, but who supported their children — for example, by helping with housework.

In contrast, about half of those who did not help others died within five years, the researchers discovered.

The researchers were also able to show that this positive effect of caregiving on mortality was not limited to help and caregiving within the family. The analysis showed that childless older adults who provided others with emotional support, for example, also benefited. Half of these helpers lived for another seven years, whereas non-helpers lived for only another four years.

“But helping shouldn’t be misunderstood as a panacea for a longer life,” said Ralph Hertwig, Director of the Center for Adaptive Rationality at the Max Planck Institute for Human Development. “A moderate level of caregiving involvement does seem to have positive effects on health. But previous studies have shown that more intense involvement causes stress, which has negative effects on physical and mental health.”

The researchers think that prosocial behavior was originally rooted in the family.

“It seems plausible that the development of parents’ and grandparents’ prosocial behavior toward their kin left its imprint on the human body in terms of a neural and hormonal system that subsequently laid the foundation for the evolution of cooperation and altruistic behavior towards non-kin,” said  first author Sonja Hilbrand, a doctoral student in the Department of Psychology at the University of Basel.

The study was published in Evolution and Human Behavior.
