Low sugar levels could be a contributing factor in cases of domestic violence, a new study has claimed.
Researchers from several American universities tested 107 married couples with an average age of 36 who had been married for an average of 12 years, asking them to stick pins into dolls when they felt aggressive.
They found that the lower a person’s blood sugar level, the more they displayed signs of aggression which the researchers claimed could be an indicator of the potential for intimate partner violence.
The researchers suggest:
“There…was a link between aggressive impulses and aggressive behaviour. Lower levels of glucose predicted aggressive impulses, which, in turn, predicted aggressive behaviour. These findings remained significant even after controlling for relationship satisfaction and participant sex. Thus, low glucose levels might be one factor that contributes to intimate partner violence.”
The findings are not without controversy. One analysis done by medical organisation Bazian suggested the tests were too abstract to have real world implications and claimed the issue of intimate partner violence was much too complex for the results to be considered concrete.
“[T]his study used highly experimental scenarios, where married couples (with no reported experience of partner violence) were asked to carry out two abstract tests.”
“Intimate partner violence may have varied complex psychological causes, and it cannot be answered by one general simple cause, such as low blood sugar.”
