However, supportive evidence is inconsistent and is mainly from studies in high-risk groups. We estimated the effect of PA during pregnancy on systemic inflammatory markers and cytokines in mothers recruited in the Barwon infant study.<h4>Material and methods</h4>The Barwon infant study is a prebirth cohort of 1064 mothers recruited in the Barwon Region of Victoria, Australia. Participants reported their previous week's PA at their 28-week antenatal appointment using the International PA Questionnaire. Women were grouped into low, moderate, and high PA categories based on daily duration and weekly frequency of walking, moderate- or vigorous-intensity PActa obstetricia et gynecologica Scandinavica1808-1819https://www.ebi.ac.uk/biostudies/studies/S-EPMC11324931biostudies-literaturePhysical activity and circulating inflammatory markers and cytokines during pregnancy: A population-based cohort study.PMC11324931Hesketh KDO'Hely MBurgner DSmith CDawson SDowning KSominsky LMansell THyde NVuillermin PDhar PPonsonby ALTang MLKBarwon Infant Study Investigator GroupCollier FfalsePhysical activity and circulating inflammatory markers and cytokines during pregnancy: A population-based cohort study.<h4>Introduction</h4>Physical activity (PA) during pregnancy has numerous benefits, which may be mediated via effects on the immune system.
