MatTrack: The impact of preconception maternal weight trajectories on maternal, pregnancy, and child outcomes
Aims: 1. Determine maternal preconception weight trajectories associated with (a) recommended GWG (total and trimester-specific) and (b) lowest PPWR at 4-6 weeks and 12 months postpartum. 2. Determine maternal preconception weight trajectories associated with the lowest risk of adverse pregnancy outcomes: gestational diabetes, gestational hypertension/preeclampsia, and cesarean section. 3. Determine maternal preconception weight trajectories associated with the lowest risk of adverse child outcomes: preterm birth, size for gestational age at birth (small [SGA], appropriate, large [LGA]), infant growth trajectory, and BMI at 3 years of age.
