Impact of Physical Activity During Pregnancy on Cardiac Variability in Newborns

Condition(s) studied

Investigational drug(s) / intervention(s)

Heart rate variability: A Holter ECG recording will be performed on the child's second night for a minimum of 6 hours.

Pulmonary function: Oximetry recording will be performed on the child's second night for a minimum of 6 hours.

Study summary

Ancillary study of the PregMouv study which aims to evaluate an intervention allowing the best adherence of women in terms of physical activity. Several types of interventions are therefore planned in this study: no intervention, physical activity sessions in person, by videoconference or mixed (in person and videoconference) with accelerometer assessment of the level of physical activity practiced (in the form of energy expenditure, in MET). Thus, for our ancillary study, a comparison of the cardiac variability of newborns will be carried out according to the level of physical activity practiced by the mother regardless of the intervention she benefited from within the framework of the PregMouv study. A comparison of the average saturation and the time spent below 90% saturation will be carried out via a continuous recording of saturation by oximetry. A longitudinal follow-up for the assessment of height and weight growth (from growth curves) and neurodevelopment (by clinical examination and self-questionnaire) is also planned until the child is 2 years old.

Eligibility

Primary outcome measure(s)

• Heart rate variability — during the child's second night.
  Is measured by SDNN (standard deviation of all normal R-R intervals), a reflection of the variability of the global autonomic nervous system of newborns, obtained from a Holter ECG recording.
