Table 6 Correlations between sleep and physical activity in children 6–12 years
From: Sleep and physical activity patterns in adults and children with Bardet–Biedl syndrome
Children (n = 39) | Time in bed (h/day) | Total sleep time (h/day) | Sleep efficiency (%) | Sleep fragmentation index (%) |
|---|---|---|---|---|
Median duration of prolonged sedentary bouts (min) | r = 0.20 p = 0.24 | r = 0.27 p = 0.11 | r = 0.45 p = 0.006 | r = − 0.23 p = 0.17 |
Total prolonged sedentary bout time (min/day) | r = − 0.51 p = 0.001 | r = − 0.50 p = 0.002 | r = − 0.19 p = 0.28 | r = 0.42 p = 0.01 |
Total activity Z-score (standard deviations) | r = 0.36 p = 0.03 | r = 0.36 p = 0.03 | r = 0.20 p = 0.24 | r = − 0.19 p = 0.26 |
