“…In a study of normotensive women with mid‐trimester 24‐h blood pressure monitoring, higher mean diastolic blood pressure within the ‘normal’ range was found to be associated with lower birthweight. 131 Among women who had no clinically recognised maternal vascular disease, but who had spontaneous deliveries at 22–32 weeks, mean maternal blood pressure on admission was positively correlated with severity of uteroplacental vascular lesions 132 . A third study in normotensive pregnant women found that increases in diastolic blood pressure in response to a stressful arithmetic task were correlated with an increased risk of PTD 133 …”

In light of the social/ethnic disparity in preterm delivery (PTD) rates, the Pregnancy Outcomes and Community Health (POUCH) Study takes a broad view of the determinants of PTD by attempting to link underlying biological and psychosocial factors. The relationships between placental pathology, maternal biomarkers, and antecedent psychosocial factors are evaluated in three hypothesised pathways of PTD – one characterised primarily by infection, one by maternal vascular disease, and one by premature elevations in corticotropin releasing hormone in the absence of histological evidence of placental pathology. Within each pathway, an emphasis is placed on understanding the roles of stress and of maternal serum alpha‐fetoprotein, an early biomarker associated with PTD. The POUCH Study enrols pregnant women from five Michigan communities. Information about these women and their environments is gathered through detailed interviews and collection of biological samples including hair, urine, saliva, blood, vaginal fluid, and vaginal smear at 15–26 weeks of gestation. We have chosen to focus on the second trimester – a time when pathological processes may have evolved to a detectable stage, but generally before the onset of biological changes that accompany labour. This focus is consistent with the long‐range goal of early detection/intervention and prevention of PTD.
