Table 2.
Neonatal and maternal hair glucocorticoid concentrations and ratios. Median and IQR of hair glucocorticoid concentration in pg/mg.
| Term- Time-point 1 (< 10 days after delivery) | Preterm- Time-point 1 (< 10 days after delivery) | Preterm- Time-point 2 (6 weeks after delivery) | ||
|---|---|---|---|---|
| Maternal hair | Hair cortisol concentration | 5.7 (3.4–13.6)** | 5.0 (2.1–8.6) | NA |
| Hair cortisone concentration | 16.9 (11.4–25.3)* | 15.0 (6.2–19.1) | NA | |
| Hair cortisol to cortisone ratio | 0.36 (0.27–0.59) | 0.35 (0.26–0.44) | NA | |
| Neonatal hair | Hair cortisol concentration | 401 (252–615)*** | 106 (66–164) | 82 (55–169) |
| Hair cortisone concentration | 156 (135–192)*** | 65 (38–97) | 94 (72–126)*** | |
| Hair cortisol to cortisone ratio | 2.4 (1.8–3.9)*** | 1.3 (1.0–2.4) | 0.9 (0.6–2.0)*** |
In the term (time-point 1) column this represents results of term vs preterm postnatal hair glucocorticoids tested by independent t-test. In the preterm (time-point 2) column this represents results of preterm time-point 1 vs time-point 2 hair glucocorticoids tested by paired t-test.
