Prevalence and Factors Associated with Preterm Birth
Prevalence and Factors Associated with Preterm Birth
Keywords:
preterm birth, prevalence, associated factorsAbstract
Preterm birth is a major determinant of neonatal morbidity and mortality. The causes of preterm birth are complex and multifactorial. This survey aimed to determine prevalence and factors associated with preterm birth in south zone of Mae Hong Son Province. The data of pregnancies which delivered at Mae Sa Riang Hospital, Mae La Noi Hospital and Sop Moei Hospital between October 2019 and August 2022 were extracted. In total 3,559 pregnant women were enrolled; 448 preterm births were taken as a case and 3,111 term births were taken as a control group. Hospital and labor records were reviewed. Multiple logistic regression was applied to identify factors associated with preterm birth. This study found that the prevalence of preterm birth was 12.6%. The statistically significant factors that affected preterm birth were history of preterm birth (OR = 3.619, 95%CI 2.637-4.965, p < 0.000) and entering ANC after 12 weeks (OR = 1.307, 95%CI 1.045-1.635, p = 0.019). Therefore, proactive service should be provided for optimal antenatal care, pregnancy risk identification, individual care plan and progesterone usage according to indication in order to reduce preterm birth rate in remote area
