Artificial neural networks (ANNs) offer a novel, non-invasive method for early preterm birth prediction. This approach shows potential for screening low-risk populations, improving upon current costly clinical tests.

Area of Science:

  • Obstetrics and Gynecology
  • Medical Informatics
  • Computational Biology

Background:

  • Current preterm birth prediction relies on costly, invasive clinical testing, primarily for high-risk populations.
  • There is a need for accessible, non-invasive screening tools for broader maternal populations.

Purpose of the Study:

  • To evaluate the efficacy of artificial neural networks (ANNs) for early preterm birth prediction.
  • To assess the potential of ANNs in estimating obstetrical outcomes in low-risk maternal populations.
  • To compare ANN performance with and without artificial data augmentation.

Main Methods:

  • A back-propagation feedforward artificial neural network (ANN) was utilized.
  • The ANN was trained and tested using eight input variables from obstetrical history before 23 weeks gestation.

  • Artificial training sets were generated to address underrepresented preterm birth cases, increasing their distribution to 20%.

    • Main Results:

    • Training on a refined high-risk preterm birth model significantly improved network sensitivity to 54.8%.
    • The non-artificially distributed preterm birth model achieved a sensitivity of just over 20%.
    • ANNs demonstrated potential for risk estimation in heterogeneous and low-risk maternal populations.

    Conclusions:

    • Artificial neural networks present a promising complementary approach for early preterm birth prediction.
    • ANNs can be effectively employed as a screening tool, utilizing readily available obstetrical data.
    • Data augmentation techniques can enhance ANN sensitivity for predicting high-risk preterm birth outcomes.
