Weight gain: adjusted for pre-pregnancy BMI, age, education, race

Systolic BP: adjusted for BMI, HTN

Diastolic BP: adjusted for age, BMI, HTN

Glucose: adjusted for BMI and history of GDM

Abbreviations: kg= kilograms; BP= blood pressure; mm/Hg= millimeters of mercury; mg/dL= milligrams per deciliter; std β= Standardized beta; PA= physical activity; SED= sedentary behavior; Δ= change from pre-pregnancy to the specific trimester
