A link between a stressful pregnancy and negative outcomes is hardly surprising, but Dr Monique Robinson of Perth’s Telethon Institute for Child Health Research found that “it is the overall number of stresses that is most related to child behaviour outcomes”. The type or timing of incidents, however, did not seem to matter.

Robinson admits it is hard to measure the severity of stressful incidents so she classified stresses by cause, such as the death of a relative, financial concerns and relationship break-ups. Despite dividing these challenges in different ways, she found no sign that some caused more problems during childhood than others.

Robinson also attempted to control for socio-economic factors and problems that continued to show up after birth, although she says this can be difficult.

“Two or fewer stresses during pregnancy are not associated with poor child behavioural development but, as the number of stresses increases to three or more, then the risks of more difficult child behaviour increase,” Robinson says. More than one-third of women in the 3000-strong Raine longitudinal study suffered three or more stressful events during their pregnancy, while 7.6% suffered six or more.

Rather than stressing expectant mothers further, Robinson emphasises that the link is statistical. “Regardless of exposure to stress in the womb, a nurturing...
