Comparison of Risk Factors and Outcomes of Delivery between Preterm and Term Delivery at Huayod Hospital, Trang Province

Abstract

The objective of this study was to assess the risk factors and outcome of delivery between preterm and term delivery at Huayod Hospital. This was a prospective descriptive study at a local secondary center-hospital (Huayod) in southern Thailand during 1 September 2015 to 31 September 2016.The study group consisted of 824 pregnant women who came for antenatal care. The collected data included demographic characteristics, obstetrics history, medical and obstetrics complication, gestational age at delivery and newborn data. Three hundred and thirty-one cases (40.0%) had at least one risk factor for preterm delivery. Eighty three cases (25.1%) delivered between 28 and 37 weeks. Comparison was made between those who delivered at 28-37 weeks of gestation (study groups) to women who delivered at term (>37 weeks). Maternal age of preterm delivery were 25±7.8 (15-42) years old and had body mass index (BMI) of 23.36 kgs/m² (SD±3.71, 95%CI 17.0-34.2). Maternal age of term delivery were 28.8±7.7 (13-43) years old and had BMI of 24.12 kgs/m² (SD±2.78, 95%CI 16.5-35.1). Most pregnant women had lower education (below high school) and had more stress during pregnancy. The SPSS 11.5, Continuity Correction, Fisher’s exact and Chi-square test, were used to analyze the data. There was no risk factor that significantly associated with preterm delivery. All risk factors had no statistically significant association with preterm delivery.
