Table 4.
Descriptive sleep quotas (n = 51, men = 23) and NPCRA analysis (n = 31, men = 17) comparing women and men in the BaYaka study sample.
| Women | Men | Bayes factor or t-test | BF interpretation | |
|---|---|---|---|---|
| Sleep quotas | ||||
| Sleep onset | 20:53 (1:24) | 21:18 (1:41) | t = − 2.54, p = 0.01 | |
| Sleep end | 5:36 (0:29) | 5:47 (1:56) | t = − 1.27, p = 0.21 | |
| Time in bed (h) | 9.06 (1.40) | 8.83 (1.88) | 0.28 | Weak evidence for H0 |
| Total sleep time (h) | 6.15 (1.37) | 5.73 (1.50) | 5.31 | Modest evidence for H1 |
| Twenty-four hour total sleep time (h) | 6.92 (1.73) | 6.98 (1.91) | 0.41 | Weak evidence for H0 |
| Nap period duration (h) | 0.77 (1.06) | 1.26 (1.09) | 731.2 | Very strong evidence for H1 |
| Wake after sleep onset (h) | 2.57 (0.94) | 2.50 (1.23) | 0.13 | Weak evidence for H0 |
| Sleep efficiency (%) | 67.64 (10.77) | 65.18 (11.70) | 0.93 | Weak evidence for H0 |
| Sleep fragmentation | 50.28 (17.46) | 50.65 (18.64) | 0.12 | Weak evidence for H0 |
| Non-parametric circadian rhythm analysis | ||||
| Relative amplitude | 0.90 (0.04) | 0.83 (0.10) | 3.02 | Modest evidence for H1 |
| Interdaily stability | 0.59 (0.10) | 0.51 (0.11) | 1.66 | Weak evidence for H1 |
| Intradaily variability | 0.08 (0.04) | 0.14 (0.05) | 30.93 | Very strong evidence for H1 |
| L5 | 1854.78 (525.82) | 2538.88 (2014.54) | 0.61 | Weak evidence for H0 |
| M10 | 38,673.07 (13,420.28) | 26,539.06 (5,085.21) | 19.76 | Strong evidence for H1 |
| M10 onset | 7:42 (0:28) | 7:14 (0:34) | t = 2.59, p = 0.01 | |
Data are reported as mean (standard deviation). Bayes factor is reported to assess differences in sleep quotas between genders. Time value difference (sleep onset, sleep end, and M10 onset) is assessed using a t-test.
