Abstract:
PURPOSE: To identify the potential risk factors for preterm birth (PTB) in women with advanced maternal age in the Korean population. METHODS: We selected the data of 531 pregnant women and singletons in the Korean Preterm Collaborate Network Study. Among the data, we analyzed variables related to demographic characteristics, lifestyle factors, and delivery information. Maternal age was divided into two groups: younger ( < 35 years) and advanced (≥35 years). Multiple logistic regression analysis was performed to identify the potential risk factors for PTB in advanced maternal age. RESULTS: In advanced maternal age, education level, occupation, passive smoking, iron intake, and parity showed significant differences between term birth and PTB. In particular, women who were exposed to passive smoking (odds ratio [OR]=2.83, confidence interval [CI]=1.14~7.04) and had folic acid intake during pregnancy (OR=2.67, CI=1.11~6.43) were at a significantly increased risk of PTB, after adjusting for all variables. CONCLUSION: This study indicates that smoking and lifestyle factors are the potential risk factors for PTB in advanced maternal age.
