The aim of this studywas to determine the relation between TTP and pregnancy outcome.Methods : This study was a case cohort study that was done in Shahid Beheshti Educational Hospitalduring 2006-2007. Women aged 18-35 years, who had only one pregnancy without using any contraceptionmethod before pregnancy and delivered their first child, were enrolled in this study. Thus, 801 women wereselected and followed up for pregnancy outcome and TTP until the end of pregnancy. All the participantsfilled in a special questionnaire. Finally the collected data were entered into computer and analyzed bySPSS ver. 20 software.Results : The frequency distribution of TTP-based pregnancy outcome showed that TTP > 48 weeks washigher in normal delivery than in abnormal delivery (5.6% vs. 19.4%). According to Chi-square test, thefrequency distribution of pregnancy outcome was related to TTP (P < 0.001).Conclusion : According to the results of this study, there is a significant relationship between TTP andpregnancy outcome, and TTP may lead to unwanted complications such as ectopic pregnancy, pretermlabor, and abortion.
