Biopsychosocial predictors of preterm delivery.

Aim: The aim of this study is to integrate a psychosomatic approach in the investigation of causes for preterm deliveries. Methods: A prospective study including 589 pregnant women between the 13^th and the 24^th gestation week (GW) was performed. In addition to medical and sociodemographic risk factors for preterm birth, factors such as biographical information, coping strategies and personality factors, pregnancy-related attitudes and anxieties as well as the pregnant women's social environment were examined. A factor analysis was performed using a principal component method with subsequent varimax rotation. Results: Psychosocial variables were found to have a significant influence on the course of pregnancy and delivery. A total of 29 pregnant women (5.8%) delivered prematurely before they completed the 37^th GW. Lack of support, poor emotional understanding by the partner, and additional stress subsequent to gynecological disorders were significantly associated with prematurity delivery. Pregnancy-related fears and general anxiety were additional significant predictors for preterm delivery. Conclusions: Partner relationships, women's support groups, psychosomatic reactions due to problems with reproductive functions, and anxiety deserve special attention for the prevention of preterm birth.
