Stress and hair cortisol concentrations from preconception to the third trimester.

ABSTRACT: Stress is an important and modifiable determinant of health, and its association with hair cortisol concentrations (HCC) during pregnancy remains unclear. We selected a random sample of 97 participants from a cohort of pregnant participants attending prenatal clinics in Lima, Peru. Each provided a hair sample at enrollment (mean gestational age = 13.1 weeks) and again at full-term delivery. Hair samples were segmented to reflect HCC in preconception and each trimester. At enrollment, measures of stress included: difficulty accessing basic goods, educational attainment, exposure to violence, fair or poor general health, perceived stress, and symptoms of depression, general anxiety, and post-traumatic stress disorder. Linear mixed models evaluated the association between each stress measure
