Predicting Factors Associated with Preterm Birth of Pregnant Women at Somdejphrajaotaksinmaharaj Hospital

Abstract

BACKGROUND: Preterm birth was the condition in which a pregnant woman has childbirth before 37 weeks of gestation. The effects of preterm birth can lead to disabilities and disabilities for surviving babies, a significant problem in public health and obstetrics-gynecology at present.

OBJECTIVES: To study predicting factors associated with preterm birth of pregnant women at Somdejphrajaotaksinmaharaj Hospital.

METHODS: This research was a case-control study. The data collection period was three years (Fiscal Year 2019–2021). The sample group was divided into (1) the study group: 155 women who had a preterm birth, and a control group: 347 pregnant women who could stop preterm birth and maintained an average term birth. The research instrument was a pregnant women’s data record designed by the researcher. Data analysis by using descriptive statistics, univariable and multiple logistic regressions with the statistical significance at 0.05.

RESULTS: The most samples were 27.1±6.3 years old, Gestational Age (GA) of labor pain at 33.5±3.0 weeks, and BMI before pregnancy was 23.3±4.7 kg/m². Factors that could predict preterm birth in pregnant women include: (1) premature rupture of the membrane was found to have preterm birth 3.59 times (95%CI:2.32-5.55), and (2) cervical length less than 2.5 centimeters were found to have preterm birth 5.08 times (95%CI: 3.22–8.04).

CONCLUSIONS: Premature rupture of the membrane and cervical length were predicting factors associated with preterm birth of pregnant women. Therefore, to prevent preterm birth in pregnant women in the future, we should set guidelines for the surveillance and following of pregnant women by considering to these factors.
