Self-Reported and objectively measured physical activity among a cohort of postpartum women: the PIN Postpartum Study.

ABSTRACT:

Background

Few studies measure physical activity objectively or at multiple time points during postpartum. We describe physical activity at 3- and 12-months postpartum among a cohort of women using both self-reported and objective measures.

Methods

In total, 181 women completed the 3-month postpartum measures, and 204 women completed the 12-month postpartum measures. Participants wore an ActiGraph accelerometer for 1 week and completed in-home interviews that included questions on physical activity. A cohort of 80 women participated at both time points. Poisson regression models were used to determine whether physical activity differed over time for the cohort.

Results

For the cohort, average counts/minute were 364 at 3-months postpartum and 394 at 12-months postpartu
