Abstract
Description
This repository contains de-identified data from labouring participants, organised into three BMI groups: C (normal weight), OW (overweight), and O (obesity). Original continuous transabdominal recordings (nominal 21 min) were acquired with the Babycard maternal–fetal monitor at Fs = 1000 Hz.RR/ holds maternal inter-beat interval (IBI) series from the full clinical sessions (~20–50 min); analyses used 21 min per participant after discarding the first minute to remove start-up artefacts. RR units are milliseconds. For downstream analyses, RR series were resampled to 20 Hz.CSI_CVI/ contains autonomic indices computed with the Candia-Rivera method. Each file has two columns: (1) time (minutes) and (2) the normalised (Z-score) CSI or CVI time series derived from the time-resolved Poincaré algorithm.X_envelopes/ and Y_envelopes/ provide TOCO-like envelopes derived from EHG along orthogonal components X and Y (nV). Each file contains 24,000 samples at 20 Hz, corresponding to the 20-minute analysed window (after discarding the first minute).An accompanying Excel file (clinical_data.xlsx) includes per-participant clinical metadata: ID, Age (years), Weight (kg), BMI (kg/m²), Gestational age (weeks), Systolic Pressure (mmHg), Diastolic Pressure (mmHg), Temperature (°C), Cervical Dilatation (cm), Cervical Effacement (%), and Number of contractions in 10 minutes.File names encode the group label (C/OW/O) and subject ID. The dataset enables BMI-stratified studies of maternal autonomic dynamics and uterine activity during labour, including replication of RR-based CSI/CVI analyses and their coupling.
