In the Stress Processes and Pregnancy Lab Prof. Dunkel Schetter and collaborators examine various aspects of prenatal maternal stress including stress exposures, emotional responses, and appraisals of stress and their effects on preterm birth and low birthweight. This program of research involves prospective longitudinal studies of thousands of pregnant women of diverse race and ethnicity and socioeconomic status including low income, Hispanic and African American women. The lab has also focused on unique risk and resilience factors and mechanisms involving African American and Latina women and preventive interventions.
Prof. Dunkel Schetter and associates have documented that prenatal anxiety reliably predicts time of gestation and that corticotrophin releasing hormone (CRH) is involved in the mechanisms responsible for earlier births. In addition, we have examined the HPA axis in pregnancy and published findings involving levels of ACTH and cortisol as well as CRH at various times in pregnancy, and as significant correlates of self-report psychological measures.
For the past ten or more years Prof. Dunkel Schetter has been engaged in work with the NICHD funded Community Child Health Network (CCHN) that conducted a community collaborative national study on SES and racial/ethnic disparities in maternal and child health, which focused on fathers as well as mothers. This work has yielded many papers on a large range of topics emphasizing mothers and fathers of color and of low income. (See Projects for a full list)
A follow-up study of a portion of the CCHN cohort led by Prof. Dunkel Schetter examined children of a subsequent birth and their mothers permitting examination of preconception maternal factors predicting birth and early child outcomes. That work along with another cohort study (Healthy Babies Before Birth/HB3) in Los Angeles and Denver include consideration of neuroendocrine, immune, epigenetic, and gene expression processes in maternal child outcomes.(See Projects)
