Insights
Children born very preterm (VPT) face higher risks for generalized anxiety disorder and attentional problems by age 17. Early identification and support are crucial for these individuals. This study highlights the long-term psychological impact of VPT birth.
Area of Science:
- Developmental Psychology
- Child Psychiatry
- Neonatal Medicine
Background:
- Very preterm (VPT) birth is a known vulnerability factor impacting lifelong physical and mental health.
- Psychiatric illness in VPT adolescents can disrupt developmental tasks and life trajectories.
- Understanding the psychological burden in VPT individuals during adolescence is critical.
Purpose of the Study:
- To determine the prevalence of psychiatric disorders in VPT and full-term (FT) control cohorts at age 17.
- To examine the magnitude of psychological burden associated with VPT birth.
- To assess the risk of psychiatric disorders during a key developmental transition period.
Main Methods:
- A prospective longitudinal cohort follow-up study.
- Clinical interviews were conducted with VPT and FT adolescents and their caregivers by an adolescent psychiatrist.
- Rates of psychiatric disorder were ascertained through standardized clinical assessments.
Main Results:
- VPT birth was associated with a significantly higher risk of generalized anxiety disorder (RR 2.33) and attentional problems (RR 3.46).
- Caregivers reported social and communication difficulties in VPT adolescents, but autistic spectrum disorder did not reach clinical group differences.
- No significant differences in other psychiatric disorders were found between VPT and FT control adolescents.
Conclusions:
- Longitudinal follow-up demonstrates increased rates of clinically significant psychiatric disorder in VPT individuals at age 17.
- Awareness of increased psychiatric risks is essential for families and healthcare professionals.
- Timely monitoring and effective mental health interventions are recommended for VPT adolescents.
Aim:
Very preterm (VPT) birth is a known early vulnerability factor, impacting both physical and mental health over the life-span. The additional burden of psychiatric illness in VPT adolescents is likely to adversely affect critical developmental tasks and personal, social and academic/vocational trajectories. Our aim was to examine the magnitude and extent of the risk of psychological burden by determining the prevalence of psychiatric disorders in our prospectively followed-up VPT and full-term (FT) control cohorts, in this period of developmental transition at age 17 years.
Methods:
Rates of psychiatric disorder in the VPT and FT control cohorts were ascertained at clinical interview of the adolescents and their care giver(s) by an adolescent psychiatrist.
Results:
VPT birth was associated with a greater risk of generalised anxiety disorder (VPT vs. FT risk ratio (RR) 2.33; 95% confidence interval (CI): 1.16, 4.67, P = 0.02), as well as attentional problems (VPT vs. FT RR 3.46; 95% CI: 1.01, 11.88, P = 0.03). Although care givers of VPT adolescents reported many social and communication difficulties, and observation at clinical interview supported this, our data did not reach clinical threshold for group differences in autistic spectrum disorder. For all other psychiatric disorders, there was no difference between VPT and FT control adolescents.
Conclusion:
Our longitudinal cohort follow-up study examining the late effects of VPT birth has demonstrated increased rates of clinically significant psychiatric disorder in this period of important developmental transition. Families and health professionals need to be aware of the increased risk so they can monitor for symptoms and seek effective mental health treatments and support.
