Preconception to postpartum accelerometry-based 24-hour movement behaviors: a prospective cohort study.

ABSTRACT:

Background

Changes in movement behaviors - physical activity (PA), sedentary behavior, and sleep patterns - across preconception, pregnancy, and postpartum are associated with maternal and child health but remain understudied. Longitudinal accelerometer-measured data, including weekday-weekend differences, are lacking. Understanding these patterns is essential for developing targeted interventions that account for lifestyle variations. We investigated longitudinal changes in PA, sedentary behavior, and sleep patterns throughout preconception, pregnancy, and postpartum using prospectively collected accelerometry data.

Methods

In a Singapore prospective preconception cohort, women aged 18-45 wore an accelerometer on their non-dominant wrist for seven days during preconception
