The cohort was defined as participants that completed the accelerometer portion of the study at both 3- and 12-months postpartum.
There were no transportation activities that were >=4.8 METS so it is not reported.
p-value is on the cohort sample from GEE models adjusted for age at 3-months postpartum, education, BMI at 3-months postpartum, and change in BMI from 3- to 12-months postpartum Moderate to vigorous hours/week included activities that were self-reported as “somewhat hard” and “hard or very hard”.
Total hours per week included activities that were self-reported as “fairly light”, “somewhat hard”, and “hard or very hard”.
Moderate to vigorous MET-hours per week was classified using >=3 METS and >=4.8 METS.
