Behavior in Pregnancy Study (BIPS): 1992-1995

Study Goal:

To differentiate between the contributions of psychological stress and physical strain or exertion to preterm delivery and low birthweight. Both of these factors are associated with poor perinatal outcome. However, few studies focus on the separable and confounding         effects of psychological stress and physical exertion or strain controlling for other                   determinants of birth outcomes such as medical complications, demographics and health   behaviors.

Design:

A prospective and longitudinal study was conducted of over 400 women recruited from public, private and managed health care settings (HMOs). The sample was diverse in            ethnicity, maternal risk conditions and parity. Women entered into the study before 20 weeks gestation and were studied at three times prenatally and once postpartum                    assessing   perceived stress and physical strain through interview and biochemical                  samples (urinary catecholamine and plasma cortisol, CRH) as well as biophysical                      parameters (ultrasound at each visit). Health behaviors and social support were also              assessed. Outcomes were obtained from medical charts.
