Pregnancy Outcomes Among Individuals With Cerebral Palsy: A Population-Based Cohort Study

Introduction

Cerebral palsy (CP), a neurological condition affecting movement and posture, presents unique challenges during pregnancy. This landmark Canadian study examines how CP impacts maternal and neonatal health outcomes, addressing a critical gap in reproductive healthcare research for this population.

Study Design and Methodology

Researchers analyzed health records of over 2.2 million pregnancies in Ontario, Canada (2004-2023), comparing 1,400 pregnancies in individuals with CP against pregnancies without CP. Using modified Poisson regression models, the team calculated risks while adjusting for socio-demographic factors like income, education, and rural/urban residence, followed by adjustments for clinical characteristics. The comprehensive approach ensured statistically robust comparisons of maternal, neonatal, and non-obstetric outcomes.

Key Maternal Health Findings

Individuals with CP faced substantially elevated risks: 79% higher likelihood of severe maternal morbidity/mortality and 86% increased risk of hospital readmission postpartum. Cesarean delivery rates were 38% higher compared to non-CP pregnancies. These risks persisted even after accounting for clinical factors, suggesting CP itself significantly impacts pregnancy physiology beyond associated conditions.

Neonatal Health Outcomes

Newborns of parents with CP showed concerning trends: 67% increased risk of preterm birth, 34% higher chance of being small for gestational age, and 77% elevated risk of congenital anomalies. Most alarmingly, severe neonatal morbidity/mortality was 48% more common. These findings indicate that CP-related factors may affect fetal development and birth outcomes.

Non-Obstetric Medical Complications

The perinatal period revealed striking neurological vulnerabilities: seizure disorders occurred over 13 times more frequently in CP pregnancies, while urinary tract infections were 50% more common. These complications likely stem from pre-existing neurological differences and mobility challenges associated with CP, emphasizing the need for targeted monitoring.

Clinical Implications and Care Recommendations

These findings necessitate specialized care approaches: Enhanced preconception counseling should address individualized risk profiles, while pregnancy requires coordinated monitoring by OB/GYNs, neurologists, and physical therapists. Key recommendations include: 1) Early anesthesia consultation for pain management planning 2) Urological assessment for UTI prevention 3) Seizure management optimization 4) Postpartum support systems addressing mobility challenges during newborn care. Multidisciplinary teams are crucial for navigating the complex intersection of neurological and obstetric needs.

Conclusions and Future Directions

This study provides robust evidence that CP significantly elevates risks across all pregnancy domains. Beyond immediate clinical implications, it highlights systemic gaps in reproductive healthcare for people with disabilities. Future research should explore how specific CP subtypes (e.g., spastic vs. dyskinetic) differentially affect outcomes and investigate tailored interventions to mitigate risks. Healthcare systems must prioritize accessible, collaborative care models for this growing patient population.
