SUMMARY:Delaney Knorr\, Duke University -- Title: Evolutionary Constraints on Human Pregnancy: How Social Environments and Energetic Limits Shape Maternal-Fetal Health
DESCRIPTION:Abstract: Human pregnancy is an energetically demanding and socially embedded process that requires mothers to balance competing physiological needs while maintaining fetal development. In this talk\, I integrate biocultural and mechanistic approaches to examine how social\, ecological\, and energetic environments become biologically embedded during gestation. Drawing on mixed-methods research with Latina women in the U.S.\, I show how neighborhood context\, discrimination\, and sociopolitical stress shape maternal psychological distress\, and how support from allomothers buffers these effects. I then present evidence from immunological and placental biology indicating that maternal stress is linked to reductions in regulatory T cells and placental extracellular vesicles\, revealing potential pathways through which social experience influences maternal-fetal communication and immune tolerance. Finally\, I discuss findings from a project measuring total energy expenditure in pregnancy using doubly labeled water to test whether physical activity and psychosocial stress push gestation toward a metabolic ceiling. Together\, this work highlights how social environments and energetic constraints jointly structure maternal-fetal trade-offs. \nZoom link for those unable to attend in person: \nhttps://ucla.zoom.us/j/94308730584?pwd=0YGsaJFEdLd5cMsOhTh465nwJubz9o.1 \nMeeting ID: 943 0873 0584\nPasscode: 308291 \n
