Early-Life Painful Exposures and Neurodevelopment in Preterm Infants Cohort

Tingting Zhao's dataset comprises a cohort of 196 preterm infants (28 to 32 weeks' gestation) followed from birth to 2 years corrected age. It quantifies painful and stressful exposures during the first 28 days of life using composite pain scores and assesses neurodevelopment at multiple time points using standardized scales. The data was last updated on 2026-05-13.

Use Cases

• Modeling the association between early-life pain scores and neurodevelopmental outcomes based on composite pain scores.
• Investigating racial disparities in pain exposure and developmental outcomes based on comparisons between Black and White infants.
• Analyzing the moderating role of sex on motor score outcomes based on comparisons between male and female infants.
• Studying the protective effect of mother's own milk intake on pain exposure levels.

Strengths

• Cohort of 196 infants provides a specific sample size for analysis.
• Longitudinal design follows infants from birth to 2 years corrected age.
• Uses multiple standardized neurodevelopmental assessment scales (NICU Network Neurobehavioral Scale, Bayley-III, BITSEA).

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 small in scale at 16.1 KB, indicating limited scope.
