Purpose: Examine the physical activity (PA) and sedentary behaviour (SB) levels of 4-7 year old children across the day. Secondly, examine differences in PA and SB levels between active and less active, and between non-overweight and overweight children. Methods: All 958 children participated in the GECKO Drenthe cohort (Mean age = 5.7 ± 0.8, 52.2% boys). Daily PA was measured using the ActiGraph GT3X and was segmented into five day-segments: early-morning, morning, afternoon, late-afternoon and evening. Children’s weight status was classified based on their BMI. Repeated measures ANOVA’s and multiple linear mixed models were performed for statistical analysis. Results: The time children spent sedentary decreased from morning to afternoon, and increased in the evening again. The time children spent in LPA and MVPA increased from morning to (late-) afternoon, and in the evening it decreased again. During weekdays children showed less SB (p<0.001), more LPA (p<0.001) and less MVPA (p<0.001) in the early-morning, more SB (p<0.001) and less LPA (p=0.018) in the late-afternoon, and less MVPA in the evening (p=0.029) compared to weekend days. Between active and less active children all time segments differed, for SB, LPA and MVPA (p<0.001). Overweight children were less sedentary in the evening (p=0.041), and showed more LPA in the evening (p=0.002) and in the weekend (late-afternoon) (p=0.003) compared to non-overweight children. Conclusion: Children were most active in the (late-)afternoon, and spent most time in SB in the morning and the evening. Interventions aiming to increase the PA levels in children could gain the most progress in the late-afternoon. Interventions to prevent overweight and obesity might gain more success by focusing more on other factors than physical activity.
