(Wiley-Blackwell) Children who display multiple psychosomatic symptoms, such as regular aches and pains and sleep and appetite problems, are more than twice as likely to be experiencing physical abuse at home than children who do not display symptoms.

The association was highest in children who were physically abused and also witnessed intimate partner violence. (Source: EurekAlert! - Social and Behavioral Science)
