Psychophysiology and Pregnancy

There is considerable evidence linking psychosocial stress (e.g., stressful life events, anxiety, emotional distress, daily hassles) to a variety of pregnancy-related outcomes, including lower birthweight and shorter length of gestation (see reviews by Dunkel-Schetter, Gurung, Lobel, & Wadhwa, 2001; Stanton, Lobel, Sears, & DeLuca, 2002). It is hypothesized that stress contributes to poor pregnancy outcomes by causing wear and tear on physiologic systems, leading to dysregulation of the body’s stress response systems (McEwen & Stellar, 1993). However, it is still not clear how many physiologic systems are involved with linking stress to pregnancy outcome, what physiologic dysregulation looks like, or how these stress-physiology links may contribute to disparities in pregnancy outcomes. For example, African-American women give birth preterm and to low birthweight infants twice as often as non-Hispanic White and Latina women, and researchers have been unable to fully account for this difference.

    Research at the Mind, Body & Baby Lab uses laboratory experimental methods and prospective research designs to examine relationships between stress, physiology, and pregnancy outcomes with a goal of better understanding how these are associated. Our lab has aimed to advance our understanding of ethnic disparities in pregnancy outcomes by considering ethnic differences in how stress and physiology interact during pregnancy (e.g., Hilmert et al., in submission).
