Insights
Nonpharmaceutical interventions show limited impact on neurodevelopment in preterm children (aged 4-18 years). More rigorous, large-scale trials are needed to confirm efficacy in this vulnerable population.
Area of Science:
- Neuroscience
- Developmental Psychology
- Pediatrics
Background:
- Preterm birth affects neurodevelopment, necessitating interventions for school-aged children and adolescents.
- Existing nonpharmaceutical interventions aim to enhance cognitive and motor skills in this population.
- Systematic review to assess the efficacy and methodological quality of these interventions.
Approach:
- Comprehensive literature search across major databases (Medline, Web of Science, PsycINFO) up to May 2022.
- Inclusion criteria applied by two independent reviewers.
- Risk of bias assessed using established tools (RoB 2, RoBINS-I).
Key Points:
- 23 studies included, with interventions like Cogmed Working Memory Training®, BrainGame Brian, and physiotherapy.
- Significant bias noted in over 78% of studies (moderate or serious).
- Limited evidence suggests a constrained impact of current interventions on neurodevelopmental outcomes.
Conclusions:
- Current research on school-age interventions for preterm neurodevelopment is hampered by methodological limitations.
- There is a critical need for high-quality, large-scale clinical trials.
- Further research should focus on robust methodologies to evaluate intervention efficacy in preterm children and adolescents.
Objective:
To systematically review nonpharmaceutical interventions aiming to enhance neurodevelopment in preterm children and adolescents (aged 4-18 years).
Method:
A systematic review of the literature was conducted for all studies published up to May 1, 2022, across Medline, Web of Science, and PsycINFO databases. Studies were evaluated for inclusion by 2 independent reviewers using predetermined inclusion criteria. The Risk of Bias In Non-randomized Studies of Interventions and the Cochrane risk-of-bias tool for randomized trials (RoB 2) tools were used to assess bias in the selected studies.
Results:
Of the 1778 articles identified, 23 were included. Quality assessment revealed moderate bias in 52.2%, low bias in 21.7%, and serious bias in 26.1%. The selected studies comprised 60.9% randomized controlled trials and 21.7% pre- versus postdesigns. Interventions included Cogmed Working Memory Training® (43.5%), BrainGame Brian (13%), physiotherapy (13%), and others (30.4%). Qualitative analysis showed the limited impact of interventions on neurodevelopmental outcomes in preterm children aged 4-18 years.
Conclusion:
Despite recent efforts to use more rigorous methodologies, current research on school-age interventions for preterm neurodevelopment exhibits methodological limitations. There is a pressing need for well-designed, large-scale clinical trials to evaluate the efficacy of nonpharmaceutical interventions in this vulnerable population.
