Parenthood & Life Expectancy

The Economist:

PARENTS often complain that their lives are being shortened by the stress of having children, yet numerous studies suggest the opposite: that it is the childless who die young, not those who have procreated. Such research has, however, failed to find out whether it is the actual absence of children which causes early mortality or whether, rather, it is brought about by the state of mind that leads some people not to have children in the first place.
To resolve the point Esben Agerbo of the University of Aarhus in Denmark and his colleagues conducted an investigation that tried to take the question of wanting children out of the equation, by looking only at those people who had demonstrated a desire to be parents by undergoing in vitro fertilisation (IVF). They discovered, as they report in the Journal of Epidemiology and Community Health, that there really does seem to be something about the presence of kids which makes a difference to the length of people’s lives.
