Heavy-drinking mothers linked to their child’s path toward the justice system

The study made use of linked administrative data from Western Australia. It used records of women who had a birth recorded on the Midwives Notification System between 1983 and 2007. The exposed cohort included mothers with an alcohol-related diagnosis, which served as a proxy for heavy drinking. A comparison group of mothers with no alcohol-related diagnoses was randomly selected, matching on maternal age within race and the year of the child's birth. The study cohort included 10,211 exposed mothers and 47,688 comparison mothers. Child contact with the justice system was identified from Department of Corrective Services data -- including those 10 years or older with a justice-system record for juveniles (10 -- 17 years) and/or adults (18 years and older) from 1985 to 2011.

Children whose mothers had a maternal alcohol-related diagnosis had almost twice the odds of contact with the justice system as children whose mothers had no alcohol-related diagnosis. Additional risk was associated with being Indigenous and with markers of social disadvantage such as low socioeconomic status. Significant child-level factors associated with greater odds of justice-system contact included being male, having a mental-health diagnosis or child-protection contact, and academic failure. The authors suggest that these factors be considered in the development of targeted prevention programs.
