Keywords:

Nowadays preterm birth is a major problem of Ministry Public Health that resulting in neonatal complications. This study aimed to find associated factors about preterm birth after stopping preterm labor in Nakornping hospital. The study was conducted by retrospective cohort study method. Four hundred and sixty eligible cases were enrolled from January 1th2016 to December 31st 2018 and assigned to be a study group, singleton pregnant women who were stopped preterm labor then failed to continue pregnancy, and comparison group, singleton pregnant women who were stopped preterm labor and success of continuing pregnancy to term pregnancy. Data was analyzed by using univariable and multivariable binary regression and presented in Relative risk (RR), 95% confidence interval (CI) and p-value less than 0.05 is used as the cutoff for the significance.
After stopping preterm labor, 212 of 460 eligible pregnant women had given preterm birth, the prevalence of preterm birth was 41.6%, this study group had mean age(SD) was 27.08(6.60) years, gestational age at the first experience of labor pain was 32.15(2.75) weeks and body mass index before getting pregnant was 22.83(3.67) kg/m2. This study found that the independent factors that associated with preterm birth were gestational age at the first experience of labor pain (RR 1.51, 95% CI 1.20-1.89) and premature ruptured of membrane (RR 1.91, 95%CI 1.60-2.28). In summary, under the standard guideline to stop preterm labor, our study had shown that gestational age at the first experience of labor pain and premature ruptured of membrane were strongly related to preterm birth.
