Key result
Maternal lifetime psychiatric diagnosis was associated with a 0.24-SD higher mean heart rate (beta 0.24; 95% CI 0.03-0.4; p=0.025) and lower vagal modulation in infants at 14 months.
Why the study?
Does maternal psychopathology influence infant heart rate and heart rate variability?
Cohort (n=528)
Does maternal psychopathology influence infant heart rate and heart rate variability?
Standardized Mean Difference: 0.24 (95% CI 0.03–0.4)
p-value: p=0.025
Maternal lifetime psychiatric diagnosis and postnatal psychiatric symptoms are associated with altered infant autonomic functioning, specifically higher mean heart rate and lower vagal modulation.

May support infant autonomic monitoring in maternal psychiatric history; hypothesis-generating for intergenerational effects pending prospective validation.
Dierckx et al. (2009) conducted a cohort in Maternal psychopathology (n=528). Maternal psychopathology vs. No maternal psychopathology was evaluated on Infant mean heart rate (beta 0.24, 95% CI 0.03, 0.4, p=0.025). Maternal lifetime psychiatric diagnosis was associated with a 0.24-SD higher mean heart rate (beta 0.24; 95% CI 0.03-0.4; p=0.025) and lower vagal modulation in infants at 14 months.
