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
a

Model 1 examined overall association between third trimester cortisol secretion and gestational weight gain

b

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).
