Early-Life Painful Exposures and Neurodevelopment in Preterm Infants Cohort

A cohort of 196 preterm infants (28 to 32 weeks' gestation) was followed from birth to 2 years corrected age. The dataset likely contains composite pain scores from the Neonatal Infant Stressor Scale and neurodevelopmental assessments from the NICU Network Neurobehavioral Scale, Bayley-III, and BITSEA. It was authored by Tingting Zhao and last updated on 2026-05-13.

Use Cases

• Modeling associations between early-life pain scores and neurodevelopmental outcomes based on composite pain scores.
• Investigating racial disparities in pain-related neurodevelopmental outcomes based on findings for Black versus White infants.
• Analyzing sex-specific effects of pain exposure on motor development based on comparisons between male and female infants.
• Studying the potential protective role of mother's own milk intake on pain exposure levels.

Strengths

• Cohort size of 196 infants provides a specific sample scale.
• Longitudinal design with follow-up to 2 years corrected age.
• Uses standardized clinical assessment scales (Neonatal Infant Stressor Scale, Bayley-III).

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is very small at 16.3 KB, indicating limited scope.
