Abstract

Introduction: Preterm birth is a major cause that leads neonatal mortality and morbidity, including serious health complications. The causes of pretem birth are varied and may depend on regional contexts.

Research objectives: To examine the prevalence and factors associated with preterm birth at Ang Thong Hospital.

Research methodology: This study employed a case-control retrospective design. Data were collected from medical records and electronic databases at Ang Thong Hospital between January 1, 2022, and December 31, 2023. A total of 2,733 pregnant cases were identified, comprising 247 women who experienced preterm birth and 2,486 women who delivered at term. A sample of 145 cases was randomly selected from the preterm birth group, while all women in the term birth group were as control group. Factors associated with preterm birth were analyzed using multiple logistic regression.

Results: The prevalence of preterm birth was 9.03%. The factors associated with preterm birth included a history of preterm birth (adjusted odds ratio (Adj OR) = 2.20, 95% confidence interval (CI): 1.22 - 3.60, p < .001), medical complications (Adj OR = 4.54, 95% CI: 1.40 - 13.47, p < .001), and infections during pregnancy (Adj OR = 13.92, 95% CI: 2.16 - 88.12, p < .001).

Conclusions: Preterm birth accounted for 9.03% of birth cases at Ang Thong Hospital. The factors related to preterm births were a history of preterm birth, medical complications, and infections during pregnancy.

Implications: The findings of this study could be useful in developing prevention strategies by promoting maternal health during pregnancy and addressing identified risk factors.
