This study analyzed data from the Japan Environment and Children's Study, a nationwide prospective birth cohort study. The frequency of shared storybook reading was assessed at multiple time points up to age 3. Child development was assessed using the Ages and Stages Questionnaire-3 (ASQ-3).

The frequency of storybook reading positively correlated with the ASQ-3 scores across all developmental domains. After adjustments, frequent reading at age 3 was associated with a 5.5-point increase (95% CI: 5.0-6.0, p < 0.001) in communication scores compared to rare reading. Among children whose ASQ-3 scores fell below the cutoff at the age of 1 year, more frequent reading at subsequent ages was associated with greater score improvements.

Conclusion Frequent shared storybook reading positively correlated with the overall developmental progress in early childhood. Impact

Based on a large-scale nationwide birth cohort study, frequent shared storybook reading is positively associated with the overall developmental progress in early childhood.

Even for children with developmental delays at age one, continuous reading was positively associated with their development.
