Perinatal risk factors and reactive attachment disorder: A nationwide population-based study

Area of Science:

• Child Psychology
• Developmental Pediatrics
• Neonatal Care

Background:

• Reactive attachment disorder (RAD) is a complex behavioral condition affecting young children.
• Understanding the perinatal and obstetric factors associated with RAD is crucial for early intervention.

Purpose of the Study:

• To investigate the relationship between various perinatal and obstetric risk factors and the development of reactive attachment disorder in children.
• To identify specific risk factors that may predict RAD diagnosis in specialized services.

Main Methods:

• A nested case-control study design was employed.
• Data were sourced from Finnish national registers, including 614 cases of RAD and 2423 age- and sex-matched controls.
• Conditional logistic regression analysis was used to assess associations between risk factors and RAD.

Main Results:

• Low birthweight (<2500g) was associated with increased odds of RAD (OR 1.96).
• Gestational age <32 weeks (OR 3.72), induced labor (OR 1.34), and neonatal intensive care unit (NICU) monitoring (OR 1.67) were linked to higher RAD odds.
• Birthweight between 4000-4499g was associated with decreased odds of RAD (OR 0.49).

Conclusions:

• Significant associations were found between low birthweight, preterm birth, and NICU admission and reactive attachment disorder.
• These findings contribute to the existing knowledge base on the developmental origins of RAD.
• Identifying these perinatal risk factors can inform clinical practice and support targeted prevention strategies.
