Abstract
BACKGROUND: Preterm birth significantly impacts infant development.
OBJECTIVE: This study aims to investigate factors associated with the success of inhibiting preterm birth in pregnant women at Chiangrai Prachanukroh Hospital, Chiangrai province.
METHODS: A retrospective cohort study was conducted on a sample group of pregnant women who received interventions to prevent preterm birth. The data were collected from hospital records and patient registries from October 2022 to September 2023. The sample consists of a study group that successfully inhibited and a group that unsuccessfully inhibited. The data were analyzed using univariable and multivariable logistic regression statistics, with a significance level set at less than 0.05.
RESULTS: The sample group comprised 149 individuals, divided into a successful intervention group (77 individuals [51.67%]) and an unsuccessful intervention group (72 individuals [48.32%]). Statistically significant factors were identified, including maternal age under 35 years (adjusted OR 5.02, 95% CI 1.75 - 14.39, p-value=0.003), cervical effacement during preterm labor less than 50% (adjusted OR 4.09, 95% CI 1.36-12.27, p-value=0.012) and cervical dilation less than or equal to 1 centimeter (adjusted OR 3.14, 95% CI 1.21-8.18, p-value=0.019). Additionally, a statistically significant trend was observed for gestational age at the first episode of preterm labor greater than or equal to 33 weeks (adjusted OR 2.20, 95% CI 1.00-4.84, p-value=0.050).
CONCLUSIONS AND RECOMMENDATIONS: Maternal age less than 35 years, cervical thinning less than 50%, and cervical dilation less than or equal to 1 centimeter are significant factors indicating success in inhibiting preterm birth in pregnant women with preterm labor. Therefore, all pregnant women, especially older than 35 years, should be educated about labor pains and should intensive care since early labor pain.
