Demographic Characteristics of 266 Preschool Children in a Movement Behavior Study

A cross-sectional study of 266 preschool children aged 3–6 years, examining relationships between 24-hour movement behaviors and executive function. The dataset was created by Ling Wang and last updated on 2026-05-08. Physical activity and sedentary behavior were measured with accelerometers, sleep duration with logs, and executive function with the Early Years Toolbox.

Use Cases

• Analyzing associations between sedentary behavior and inhibitory control based on accelerometer and toolbox assessment data.
• Investigating the relationship between sleep duration and cognitive flexibility using compositional data analysis methods described.
• Modeling the effects of isotemporal substitution of sedentary time with sleep on executive function scores.
• Studying demographic characteristics as they relate to 24-hour movement behavior compositions in preschool-aged cohorts.

Strengths

• Includes data from 266 participants, providing a substantive sample size for analysis.
• Uses objective measurement tools: ActiGraph GT3X-BT accelerometers for physical activity and sleep logs for sleep duration.
• Executive function was assessed using the standardized Early Years Toolbox, covering inhibitory control, cognitive flexibility, and working memory.
• The study reports statistically significant associations (p < 0.001) with model explanatory power exceeding 10% for key outcomes.

Limitations

• Row count and specific column-level documentation are unknown, requiring field semantics to be inferred after download.
• The dataset is very small at 5.5 KB, indicating limited scope and likely a summary or demographic table rather than raw sensor data.
• The cross-sectional design limits the ability to infer causal relationships between movement behaviors and executive function.
