    This study uses electrohysterogram (EHG) signals to identify preterm birth risk. Network analysis of EHG data improves classification accuracy for term versus preterm pregnancies.

    Area of Science:

    • Biomedical Engineering
    • Signal Processing
    • Obstetrics

    Background:

    • Preterm birth is a major cause of infant mortality.
    • Early detection of preterm birth risk is crucial for intervention.
    • Uterine electrical activity is linked to contractions.

    Purpose of the Study:

    • To develop a precise method for classifying term and preterm pregnancies.
    • To extract effective features from electrohysterogram (EHG) signals.
    • To improve early identification of high-risk pregnancies.

    Main Methods:

    • Utilized Horizontal Visibility Graph (HVG) algorithm for network representation of EHG signals.
    • Applied Short-Time Fourier Transform (STFT) for time-frequency domain analysis.
    • Employed feature selection and Partition-Synthesis for imbalanced data to train Support Vector Machine (SVM) classifiers.

    Main Results:

    • Network-based features identified essential frequency components related to preterm birth.
    • Achieved high classification performance with SVM: 0.89 sensitivity, 0.93 specificity, 0.91 accuracy, and 0.97 AUC.
    • Demonstrated improved classification of term/preterm pregnancies.

    Conclusions:

    • Network analysis of EHG signals offers a promising approach for preterm birth prediction.
    • The proposed method enhances the accuracy of identifying preterm birth risk.
    • This technique can aid in timely medical interventions to prevent preterm birth.
