Table 5 Correlations between sleep and physical activity in all children 6–18 years
From: Sleep and physical activity patterns in adults and children with Bardet–Biedl syndrome
Children (n = 82) | Time in bed (h/day) | Total sleep time (h/day) | Sleep efficiency (%) | Sleep fragmentation index (%) |
|---|---|---|---|---|
Median duration of prolonged sedentary bouts (min) | r = 0.12 p = 0.29 | r = 0.14 p = 0.22 | r = 0.16 p = 0.18 | r = − 0.06095 p = 0.6060 |
Total prolonged sedentary bout time (min/day) | r = − 0.52 p < 0.0001 | r = − 0.52 p < 0.0001 | r = − 0.19 p = 0.11 | r = 0.33 p = 0.004 |
Total activity Z-score (standard deviations) | r = 0.20 p = 0.09 | r = 0.20 p = 0.10 | r = 0.06 p = 0.60 | r = − 0.20 p = 0.09 |
