New research indicates that individuals born very preterm may face persistent anxiety and mood disorders into adulthood, highlighting the need for lifelong mental health monitoring.
Very preterm birth may leave a mental-health legacy that stretches well beyond childhood, according to a new study in Pediatric Research that tracks anxiety and mood disorders from youth into adult life in people born far earlier than term. The research asks whether the emotional effects of prematurity fade with age or continue to shape psychiatric risk across the lifespan.
Very preterm birth usually means delivery before 32 weeks of gestation, when the brain and other organ systems are still developing rapidly. The neonatal period can involve intensive treatment, repeated procedures and disruption to early bonding, all of which may affect later stress regulation and emotional development. The study by N. Tsalacopoulos, R.M. Mainzer, S.C.H. Thompson and colleagues examines whether those early pressures are reflected in long-term patterns of anxiety and mood disorders.
The findings fit a broader body of research suggesting that the impact of preterm birth is not confined to the first years of life. A longitudinal study published in BMC Medicine found that people born with very low birth weight reported lower health-related quality of life from ages 20 to 32, with signs of decline over time. Another study, indexed in PubMed, found that adults born very preterm had higher difficulty scores at ages 14 and 26 than term-born peers, including more internalising and externalising problems.
More recent population-level evidence points in the same direction. A national cohort study from New Zealand found a modest overall rise in mental-health problems among adults born with very low birth weight, with particularly elevated rates of anxiety disorders and suicidal thoughts. Taken together, these studies suggest that the emotional consequences of very early birth can persist into adulthood, even if they do not affect every individual in the same way.
That said, the evidence does not support the idea that prematurity leads inevitably to psychiatric illness. Many people born very preterm do well, and outcomes depend heavily on later environment, family support, schooling and access to care. A review of extremely preterm birth and mental health found broad continuity across the lifespan, but also pointed to neurodevelopmental pathways that may help explain why some people are more vulnerable than others.
The practical message for clinicians and families is clear: birth history can matter when assessing anxiety, low mood, withdrawal or behavioural change later in life. Long-term follow-up after neonatal intensive care may need to include mental health, not just physical growth and development. As survival improves for extremely early infants, the challenge is increasingly about helping them thrive in the decades that follow.
