Implication

Cohort study demonstrates strong alignment between actigraphy and teacher-rated hyperactivity in school-aged children, indicating objective tracking captures dynamic classroom behaviors.

Key Points

Compare objective actigraphy measurements with parent and teacher hyperactivity ratings across the school day in a large pediatric cohort.
Analyzed data from N = 6,518 seven-year-olds in the Millennium Cohort Study wearing actigraphs measured every 15 minutes (Monday–Friday).
Assessed hyperactivity using parent and teacher Strengths and Difficulties Questionnaire continuous (0–10) and binary (≥7) scores.
Conducted repeated ANOVAs adjusted for sex and linear regressions across three lesson intervals (9:00–9:45 am, 11:00–11:45 am, and 1:15–2:00 pm).
Parent and teacher continuous ratings positively associated with objective activity across the school day (effect sizes = 0.015 and 0.008, respectively; both p FDR < 0.001).
Teacher-rated continuous hyperactivity showed significantly stronger associations with physical activity during late morning (Lesson 2: Z = 3.24, p FDR = 0.005) and afternoon (Lesson 3: Z = 2.80, p FDR = 0.020) compared to early morning (Lesson 1).
