Parental criminality and medical histories of delinquent children.

In clinical practice the authors observed that many of the delinquent children of psychiatrically impaired and/or criminal parents had remarkably adverse health histories. To test their clinical impression they systematically compared the medical histories of 20 delinquent children with criminal parents and 85 delinquent children with less obviously maladapted parents. They found a strong association between paternal criminality and serious medical problems in these delinquent children. On the basis of this finding the authors suggest that the behavioral manifestations resulting from such physical illness or neglect, although they appear genetic in nature, may reflect the physical and psychological consequences of parental neglect and/or battering.
