Table 1.
Descriptive sleep quotas (n = 51, men = 23) and NPCRA analysis (n = 31, men = 17) of the BaYaka from actigraphic analysis.
| Sleep quota | |
| Sleep onset | 21:05 (1:34) |
| Sleep end | 5:42 (1:25) |
| Time in bed (h) | 8.95 (1.67) |
| Total sleep time (h) | 5.94 (1.45) |
| Twenty-four hour total sleep time (h) | 6.95 (1.82) |
| Nap period duration (h) | 1.05 (1.10) |
| Wake after sleep onset (h) | 2.53 (1.10) |
| Sleep efficiency (%) | 66.4 (11.32) |
| Sleep fragmentation | 50.47 (18.04) |
| NPCRA values | |
| Relative amplitude | 0.86 (0.08) |
| Interdaily stability | 0.55 (0.11) |
| Intradaily variability | 0.11 (0.06) |
| L5 | 2230 (1550) |
| M10 | 32,019 (11,381) |
| M10 Onset | 7:27 (0:34) |
Overall age range is 17–72 years. Data are reported as mean (standard deviation). Nap period duration was calculated by subtracting TST from TTST. L5 is the activity during the 5 h of least activity during the diel cycle. M10 is the activity during the most active 10 h during the diel cycle.
