Summary
Preterm birth risk was 11.8% in Hanoi. Physically demanding work, prior pregnancy complications, and inadequate prenatal care were key risk factors for preterm birth.
Area of Science:
- Obstetrics and Gynecology
- Reproductive Health
- Epidemiology
Background:
- Preterm birth is a significant global health concern, necessitating identification of region-specific risk factors.
- Understanding determinants of preterm birth in low- and middle-income countries is crucial for targeted interventions.
Purpose of the Study:
- To determine the incidence of preterm birth in Hanoi, Vietnam.
- To identify sociodemographic and clinical factors associated with preterm birth among women in Hanoi.
Main Methods:
- A prospective cohort study was conducted with 1709 women delivering singleton live births at Hanoi Obstetrics and Gynecology Hospital.
- Logistic regression analysis identified predictors of preterm birth (gestation <37 weeks).
Main Results:
- The overall risk of preterm birth was 11.8%.
- Significant risk factors included physically demanding work, multiple prior spontaneous abortions, previous preterm birth, vaginal bleeding, and inadequate early prenatal care.
- History of intrauterine device (IUD) use with removal less than 12 months prior to pregnancy was also associated with increased risk.
Conclusions:
- Preterm birth is a considerable issue in the studied Hanoi population.
- Beyond known factors, agricultural work, physical labor demands, and recent IUD use emerged as potential contributors to preterm birth.
