| Maternal PSS | PSS Range | Risk Ratio Exp (β) |
95%CI | p Value |
|---|---|---|---|---|
| Continuous | 0–39 | 1.00 | 0.99–1.02 | 0.776 |
| Tertiles | ||||
| Low | 0–9 | Ref | Ref | Ref |
| Moderate | 10–15 | 1.01 | 0.80–1.26 | 0.945 |
| High | 16–39 | 1.06 | 0.81–1.38 | 0.657 |
Values were calculated with multivariable adjusted log-binomial model adjusted for birthweight and gestational age at birth. * Rapid weight gain is defined as a change in WFL z-score > 0.67 representing upward crossing of percentile bands on WHO growth chart.
