FDIA is rare. Incidence rate estimates range from 1 to 28 per million children, although some assume that it may be much more common. One study showed that in 93 percent of FDIA cases, the abuser is the mother or<unk>  female guardian or caregiver. A psychodynamic model of this kind of maternal abuse exists. Fathers and other male caregivers have been the perpetrators in only seven percent of the cases studied. When they are not actively involved in the abuse, the fathers or male guardians of FDIA victims are often described as being distant, emotionally disengaged, and powerless. These men play a passive role in FDIA by being frequently absent from the home and rarely visiting the hospitalized child. Usually, they vehemently deny the possibility of abuse, even in the face of overwhelming evidence or their child's pleas for help. Overall, male and female children are equally likely to be the victim of FDIA. In the few cases where the father is the perpetrator, however, the victim is three times more likely to be male. One study in Italy found that 4 out of more than 700 children admitted to the hospital met the criteria (0.53%). In this study, stringent diagnostic criteria were used, which required at least one test outcome or event that could not possibly have occurred without deliberate intervention by the FDIA person.
