Stress increases corticotropin‐releasing hormone and may ultimately result in increased uterine contractility. Stress also increases cytokine production, which independently may lead to preterm birth or increase susceptibility to infection, thereby increasing the risk of preterm birth. Finally, stress may change health behaviors that lead to preterm birth. Research findings on the relationship between stress and preterm birth have been contradictory. In this article, the authors propose a model of the relationship between stress and preterm birth, evaluate the research on stress and pregnancy outcomes, and discuss the implications for nursing practice and research.

Study findings suggest the importance of screening and identification of victims of violence. Knowledge of physical and mental health effects of violence can guide intervention, prevention, and health promotion strategies. Future research is needed to describe barriers to seeking healthcare, screening practices of college health programs, and programs to identify victims.
