Ecological Momentary Assessment of Momentary Associations Between Availability of Physical Activity Space and Physical Activity Opportunities Among Children from Rural, Urban, and Suburban Locales.

Using Ecological Momentary Assessment (EMA), this study examined associations between momentary availability of physical activity (PA) space and accessibility of PA opportunities among 608 elementary and middle school students who were participating in an obesity prevention trial in one mid-Atlantic state in the U.S. Smartphones prompted EMA surveys at random times to assess children's perceived availability of PA space and accessibility of PA opportunities during out-of-school time, three to seven times each day over seven days.

The Natural History of Portal Venous System Aneurysms.

Background: Portal venous system aneurysms (PVA) are increasingly diagnosed on cross-sectional computed tomography (CT) imaging. However, the natural history of these aneurysms is poorly understood and reports are limited to small case series.

Methods: Terms relevant to PVA were searched in radiology reports (2010-2022) with PVA presence confirmed by manual review.

A Model for Engaging Citizen Scientists: A Community-Partnered Research Collaboration to Address Inequities for Black Birthing People.

Purpose: Co-creation of a citizen-science research initiative with a collaborative team of community members and university-based scientists to address regional disparities in maternal and fetal health outcomes for Black birthing people.

Description: Citizen scientist-led projects, where community members actively contribute to each discovery step, from setting a research agenda to collecting data and disseminating results, can extend community participatory research initiatives and help reconceptualize traditional research processes. The Pregnancy Collaborative is a citizen-science research initiative and one of nine scientific committees of The Pittsburgh Study-a longitudinal, community-partnered study designed to bring together collaborators to improve child thriving.

Parents' Perceptions of Schools' COVID-19 Mitigation Strategies: A Phenomenological Study.

Background: At the onset of the COVID-19 pandemic, schools closed across the United States. Given the impact of virtual learning and lost access to school resources, schools eventually reopened with COVID-19 mitigation protocols in place. This qualitative study sought to understand parental perceptions of school-based COVID-19 mitigation strategies.
