Emotional Distress, Physical Activity and Heart Rate Variability During Pregnacny

Mobile health (mHealth) enables continuous, real-time monitoring of both physiological and psychological states, providing detailed insights into health behaviors and responses in natural settings. This study leverages mHealth tools, including wearable devices (e.g., Oura smart ring) and ecological momentary assessment (EMA), to investigate how emotional distress moderates the relationship between physical activity (PA) and heart rate variability (HRV) during pregnancy. The shared data has been anonymized/de-identified.
