OBJECTIVE: An estimation of the individual's ability to cope with environmental adversity, that is, stress resiliency, can be extrapolated by measuring cardiac vagal tone, that is, high-frequency heart rate variability (HF-HRV); indeed, higher HF-HRV is associated with health and developmental advantages for preterm neonates. Previous studies show skin-to-skin contact (SSC) improves stress resiliency; however, linkages between SSC and HF-HRV on outcomes have not been assessed. We aimed to test the hypothesis that increased SSC frequency would enhance HF-HRV, reduce neonatal morbidity, and improve developmental outcomes.
STUDY DESIGN: Weekly electrocardiograms and clinical data were obtained from 101 preterm neonates. SSC frequency was determined from the electronic medical record.
RESULTS: At postnatal week 1, frequency of SSC and HF-HRV were positively correlated (p =.02); further, multiple stepwise regressions showed higher HF-HRV and SSC predicted reduced days on ventilation and oxygen, and shorter hospital stay (p < 0.001). Higher HF-HRV predicted lower postmenstrual age (PMA) at discharge (p < 0.01).
CONCLUSION: Higher SSC frequency was associated with increased HF-HRV during the first postnatal week. SSC and HF-HRV uniquely predicted diminished neonatal morbidity throughout hospitalization. Additionally, HF-HRV uniquely predicted earlier PMA at discharge. Augmenting SSC early in life enhances stress resiliency and improves health outcomes.
