Table 4 Adjusted associations between daily LPA/segmented across the day and temporal and demographic factors

From: Objectively measured physical activity in four-year-old British children: a cross-sectional analysis of activity patterns segmented across the day

  1. aβ co-efficient represents the difference in minutes spent in light physical activity (LPA) compared to the reference category for the given time segment. Final results from a two-level random intercept models adjusted for sex, weight status, time in childcare, age child’s mother left full-time education, time of the week (weekday vs. weekend) and season (Winter: December-February; Spring: March-May; Summer: June-August; Autumn: September-November); *p < 0.05; ** p < 0.01.
