Comparison of Risk Factors and Outcome of Delivery between Preterm and Term Delivery: 1-Year Study (2008 BE) at Siriraj Hospital

Abstract

Objective: To assess the risk factors and outcome of delivery between preterm and term delivery at Siriraj Hospital during 2008. Materials and methods: During January to December 2008, 331 pregnant women who had at least one risk factor for preterm delivery were included in this study. An epidemiologic study exploring possible risk factors for preterm delivery was undertaken. The patient who had at least one risk factor was followed up until delivery. The gestational age at delivery, newborn body weight, sex and APGAR score were recorded. The tests including descriptive analysis by SPSS 11.5, Continuity Correction, Fisher’s exact and Pearson Chi-square test, were used to analyze the data. Results: From 1,024 of new pregnant women who came for antenatal care at Siriraj Hospital, 331 pregnant women had at least one risk factor for preterm delivery. Eighty three cases (25.1%) delivered during 24-37 weeks and 240 cases delivered after 37 weeks. Pregnant women with preterm delivery were 25 + 7.8 (15-42) years old and had body mass index (BMI) of 23.36 + 3.71 (17.0 - 34.2). Pregnant women with term delivery were 28.8 + 7.7 (13-43) years old and had BMI of 24.12 + 2.78 (16.5 – 35.1). Most pregnant women had the education lower than high school and much stress during pregnancy, but they were not significantly different in statistics. No evidence of all risk factors during pregnancy was associated with preterm delivery. Conclusion: No definite risk factor was associated with preterm delivery in this study.
