Estimated Difference in Total Gestational Weight Gain Associated with a 1 Standard Deviation Increase (68.82 nmol/L) in 3rd Trimester Cortisol Secretion (AUCg)
| Model | BMI Class | Estimate (95% CI) | P-value |
|---|---|---|---|
| Model 1a | Overall | −0.11 (−0.99, 0.78) | 0.82 |
| Model 2b | Normal | −0.88 (−2.56, 0.79) | 0.30 |
| Overweight | −0.41 (−1.70, 0.89) | 0.54 | |
| Class 1 Obese | 2.04 (−0.17, 4.26) | 0.07 | |
| Class 2/3 Obese | 0.08 (−2.48, 2.64) | 0.95 |
Model 1 examined overall association between third trimester cortisol secretion and gestational weight gain
Model 2 examined differences in association between third trimester cortisol secretion and gestational weight gain by pre-pregnancy BMI
All models controlled for real-time personal monitoring sub-study participation (ref: not sub-study participant), gestational age at study entry, recruitment site (ref: LAC+USC), gestational age at birth, ethnicity by birthplace (ref: Non-Hispanic), highest education level (ref: High School), age, and third trimester nausea or vomiting (ref: no nausea or vomiting).
