Insights
Preterm birth significantly increases the risk of hospitalization for complex chronic conditions in children up to age 16. These findings highlight the need for enhanced pediatric care for preterm infants throughout childhood.
Area of Science:
- Pediatric Health
- Neonatalogy
- Public Health
Background:
- Preterm birth is a major global health concern.
- Children born preterm are at higher risk for long-term health issues.
- Understanding the specific risks of complex chronic conditions is crucial for early intervention.
Purpose of the Study:
- To investigate the association between preterm birth and subsequent hospitalisation for paediatric complex chronic conditions.
- To quantify the risk across different degrees of prematurity and types of chronic disorders.
Main Methods:
- A large cohort study of 1,269,745 children born in Quebec, Canada (2006-2022).
- Classification of preterm birth: extreme (<28 weeks), very (28-31 weeks), and moderate (32-36 weeks).
- Analysis of hospitalisation for 11 categories of complex chronic conditions up to age 16, using adjusted hazard ratios (HR) and 95% confidence intervals (CI).
Main Results:
- Hospitalisation rates for complex chronic conditions were substantially higher in preterm infants (6.88 per 1000 person-years) compared to term infants (2.24 per 1000 person-years).
- Preterm birth was linked to all studied complex chronic conditions, with the highest risks for respiratory (HR 4.64), cardiovascular (HR 3.68), and neurologic disorders (HR 3.48).
- Increased risk was observed across all ages and degrees of prematurity, most pronounced in extremely preterm infants.
Conclusions:
- Preterm birth is a significant risk factor for hospitalisation due to complex chronic conditions extending into adolescence.
- Preterm children require ongoing, enhanced medical care throughout childhood and adolescence to manage these risks.
- These findings underscore the importance of long-term follow-up and support for individuals born prematurely.
Aim:
To examine the relationship between preterm birth and hospitalisation for paediatric complex chronic conditions.
Methods:
We conducted a cohort study of 1 269 745 children born between 2006 and 2022 in Quebec, Canada. We classified preterm birth as extreme (<28 weeks), very (28-31 weeks), and moderate (32-36 weeks). The outcome was hospitalisation for complex chronic conditions, including neurologic, neuromuscular, cardiovascular, respiratory, renal, gastrointestinal, haematologic, immunologic, endocrine, and neoplastic disorders up to 16 years of age. We computed adjusted hazard ratios (HR) and 95% confidence intervals (CI) for the association between preterm birth and complex chronic conditions during 9 948 734 person-years of follow-up.
Results:
Hospitalisation rates for complex chronic conditions were higher for children born preterm than at term (6.88 vs. 2.24 per 1000 person-years). Preterm birth was associated with all complex chronic conditions, especially respiratory (HR 4.64, 95% CI 4.01-5.37), cardiovascular (HR 3.68, 95% CI 3.47-3.90), and neurologic disorders (HR 3.48, 95% CI 3.21-3.77). Associations were present at all ages and for all degrees of prematurity, but were strongest with extreme prematurity.
Conclusion:
Preterm birth increases the risk of hospitalisation for complex chronic conditions up to age 16 years. Preterm children may benefit from enhanced care throughout childhood and adolescence.
