Early Mother–Newborn Skin-to-Skin Contact at Term Birth and Early Neonatal Thermoregulation Under Routine Clinical Practice

TL;DR

The study finds that brief skin-to-skin contact after birth helps maintain newborn body temperature despite short durations and interruptions.

Contribution

The novelty lies in evaluating the effectiveness of brief and interrupted skin-to-skin contact on neonatal thermoregulation under routine clinical practices.

Findings

Infants in the skin-to-skin contact group had a lower proportion of hypothermia compared to the control group.

Skin-to-skin contact was associated with transient temperature drops but better thermoregulation outcomes.

Mode of delivery was the only factor independently associated with temperature changes during skin-to-skin contact.

Abstract

Background and Objectives: Early mother–newborn skin-to-skin contact (SSC) after birth is widely recommended to support neonatal physiological stabilization, including thermoregulation. Under routine clinical practice, however, SSC may be brief or interrupted, and its effectiveness in maintaining neonatal body temperature under such conditions is less well described. This study aimed to evaluate early neonatal temperature changes under routine post-birth care practices that included brief SSC followed by separation for incubation care. Materials and Methods: This retrospective cohort study included 620 term mother–infant dyads delivered at a single regional teaching hospital. Newborns were managed according to routine clinical practice and were allocated to either a brief early SSC group or a control group without SSC. SSC duration differed by mode of delivery (approximately 10 min after cesarean section and 20 min after vaginal birth). Infant body temperature was recorded at predefined time points from birth through early incubation care. Associations between temperature changes and clinical factors, including mode of delivery, gestational age, parity, and birth weight, were analyzed. Results: No significant difference was observed between the SSC and control groups in overall changes in infant body temperature from birth to the beginning of incubation care (p = 0.245). After one hour of incubation, mean body temperature was comparable between groups (p = 0.357). Within the SSC group, infant body temperature decreased significantly during the SSC period (change from birth: −0.68 °C ± 0.35 °C; p < 0.001). At the start of incubation care, a significantly lower proportion of infants in the SSC group (22%) had body temperatures below 36.5 °C compared to the control group (32%) (p = 0.018). Multivariable analysis identified mode of delivery, reflecting differences in post-birth care routines and SSC duration, as the only factor independently associated with temperature changes during SSC. Conclusions: Under routine clinical conditions, brief and interrupted SSC was associated with transient reductions in neonatal body temperature; however, brief SSC was associated with a lower proportion of hypothermia compared with immediate incubation care, suggesting that even short periods of SSC may support early neonatal thermoregulation.
