Psychosocial factors associated with preterm uterine contractions

Background: The aim of our study was to evaluate how sociodemographic factors, psychosocial adaptation to pregnancy and well-being levels are associated with the onset of preterm uterine contractions allowing symptomatic preterm labor. Methods: In a prospective case-control design, 51 consecutive women admitted for threatened preterm labor were enrolled. The patients received standard care. The day before discharge, once contractions had been stopped, the patients were administered 2 questionnaires: the Prenatal Self-Evaluation Questionnaire of Lederman and the Psychological Well-Being Scales. Controls were enrolled among asymptomatic, healthy women attending routine prenatal care. They were matched for parity and gestational age. Results: Gestational age at inclusion ranged from 25 to 34 weeks. Fourteen cases and 4 controls delivered preterm. Cases were less educated than controls, showed a lower acceptance of pregnancy and worse relationship with others, namely with the husband, compared to controls. They also displayed a reduced environmental mastery. Conclusion: Having a low education, poor relationship with others, including the husband, and impaired coping skills appeared to be independent risk factors for the development of symptomatic preterm labor in urbanized women.
