Maternal intellectual or developmental disability and newborn discharge to protective services

Share

Background — Approximately half of women with intellectual and developmental disabilities (IDD) lose custody of their children at some point in their child’s development, but their rates of and risk factors for newborn discharge to child protective services from the birth hospitalization are relatively unknown.

Methods — We conducted a population-based study of newborns of 3,845 women with and 379,834 women without IDD in Ontario, Canada (2002-2012). We used modified Poisson regression to estimate adjusted relative risks (aRR) and 95% confidence intervals (CI) for discharge to child protective services directly from the birth hospitalization (1) comparing newborns of women with and without IDD and (2) among newborns of women with IDD according to sociodemographic, health, service, and perinatal characteristics.

Results — About 5.7% of newborns of women with IDD, compared to 0.2% of newborns of women without IDD, were discharged to child protective services (aRR 8.10, 95% CI 6.51-10.09). Among newborns of women with IDD, risk factors were maternal psychotic disorder (aRR 2.58, 95% CI 1.90-3.50), social assistance receipt (aRR 2.55, 95% CI 1.87-3.47), failure to receive an ultrasound by 20 weeks gestation (aRR 1.76, 95% CI 1.32-2.34), and receipt of < 4 prenatal visits by 36 weeks gestation (aRR 1.71, 95% CI 1.05-2.78).

Conclusions — While women with IDD are at risk for custody loss immediately post-delivery, certain subgroups are at higher risk than others. Women with vulnerabilities related to comorbid psychotic disorders, poverty, and inadequate prenatal care may benefit from tailored, behaviour-based parenting interventions before and during pregnancy to prevent maternal-newborn separations.
