    Using a 24-Hour Movement Framework to Improve Pregnancy Outcomes

    The goal of this K99/R00 Pathway to Independence Award is to better understand associations of 24-hour movement profiles during pregnancy (consisting of physical activity, sedentary behavior, and sleep) and maternal and infant outcomes. This Award includes training in the analysis of accelerometer-measured physical activity data, compositional data analysis, sleep physiology and measurement, and collection of quantitative data.

    Preventing Postpartum Depression: Exercise as Medicine

    This intervention study will randomize 200 postpartum women at increased risk of postpartum depression to an eHealth physical activity intervention and assess the efficacy of the intervention on increasing physical activity and decreasing postpartum depressive symptoms. Additionally, this study will identify actionable areas for implementation of this eHealth intervention in an integrated health care delivery system.
