Child Protection System Removal and Short-Interval Births Among Individuals With Prenatal Substance Use.

Area of Science:

• Public Health
• Maternal Health
• Child Welfare

Background:

• Child protection systems often intervene post-birth for substance-exposed infants.
• These systems are not designed for postpartum parental support.
• Maternal substance use during pregnancy presents complex challenges.

Purpose of the Study:

• To examine the association between early child protection system involvement and subsequent high-risk birth trajectories.
• To investigate the impact of postpartum child removal on maternal substance use and birth outcomes.
• To inform interventions for parents with substance use during pregnancy.

Main Methods:

• Retrospective cohort study of mothers with substance-exposed births in California (2015).
• Analysis of 6,893 births with documented prenatal drug and alcohol exposure.
• Examined child protection system removal within 30 days postpartum and subsequent birth intervals and substance exposure.

Main Results:

• 20.4% of mothers experienced child protection system removal within 30 days of birth.
• Early removal was associated with increased risk of short-interval subsequent births (aHR 1.61).
• Early removal significantly increased risk of short-interval births with documented substance exposure (aHR 3.17).
• Child separation correlated with an increase in subsequent substance-exposed births.

Conclusions:

• Early child protection system removal following substance-exposed births is associated with adverse maternal and infant outcomes.
• Findings suggest child separation does not reduce, but may increase, subsequent substance-exposed births.
• There is a critical need for integrated public health and supportive services addressing parental substance use, treatment, and family well-being.
