Mean Differences (in Hours) in Time of Peak for Possible Influencing Factors
| Cortisol | Cortisone | |||
|---|---|---|---|---|
| Influencing Factors | Peak 1 | Peak 2 | Peak 1 | Peak 2 |
| HADS score | 0:18 ± 2:00 | 6:30 ± 3:48 | -0:54 ± 6:06 | 0:36 ± 6:36 |
| POP clinic consultation | -1:36 ± 1:12 | -5:12 ± 1:42** | -1:42 ± 2:12 | -2:00 ± 2:18 |
| Season at sampling | -2:06 ± 1:24 | -2:30 ± 2:48 | -1:54 ± 4:12 | -2:12 ± 3:42 |
| Sex | -0:12 ± 2:42 | 1:00 ± 3:06 | -1:54 ± 3:12 | -0:24 ± 3:18 |
| AUCi breast milk | -3:12 ± 1:30* | -3:12 ± 3:18 | -1:00 ± 4:42 | -0:18 ± 5:18 |
| AUCg breast milk | -2:24 ± 0:54* | -6:00 ± 1:42*** | -1:18 ± 3:30 | 0:18 ± 3:42 |
Values represent mean differences ± SEM in hours as tested with t-tests.
*P value < 0.05; **P value < 0.01; ***P value < 0.001.
HADS score was dichotomized as <8 or ≥8 on the anxiety and/or depression subscore.
Season at sampling was divided into 4-month windows: 4/21 to 8/21 (summer) and 10/21 to 2/21 (winter).
AUCi and AUCg of breast milk were dichotomized as <p50 and > p50.
Abbreviations: AUCg, area under the curve ground; AUCi, area under the curve increase; HADS, Hospital Anxiety and Depression Scale; SEM, standard error of the mean.
