(909) The impact of a neonatal sleep intervention on maternal mood in the postpartum period

To determine the impact of a novel neonatal sleep intervention on maternal mood in the postpartum period in individuals with a hypertensive disorder of pregnancy (HDP) and assess the relationship between maternal mood and blood pressure.

Study Design:

In this single institution pilot randomized controlled trial, 110 individuals with a HDP were randomized to receive a neonatal sleep intervention, a SNOO smart bassinet, plus usual care of safe sleep education (n=54) or usual care alone (n=56). Individuals were included if they were 18+ years old, had a singleton term live birth of a non-anomalous infant without a prolonged neonatal intensive care unit stay, and had a new HDP without prior chronic hypertension. Remote follow-up visits conducted at 6 weeks postpartum included vital signs and subjective mood questionnaires including the Edinburgh Postnatal Depression Scale (EPDS), Generalized Anxiety Disorder 2-Item Scale (GAD-2), Perceived Stress 4-Item Scale (PSS-4), and the Breslau 7-item Post-Traumatic Stress Disorder Scale (Breslau-7). Maternal mood was a prespecified secondary outcome in this trial.

Results:

Clinical and demographic characteristics were similar between arms (Table 1). Follow-up data was available for 82 (75%) participants at 6 weeks (mean of 41.8±4.8 days) postpartum, with a higher follow rate in the SNOO arm (89% vs 61%) (Table 2). EPDS, GAD-2, PSS-4, and Breslau-7 scores were similar between the two groups (p>0.05). There was no significant correlation between blood pressure and EPDS, GAD-2, and PSS-4 scores (p>0.05) at 6 weeks postpartum. There was a significant correlation between blood pressures and Breslau-7 score (r= -0.26, p=0.02), but this is likely not clinically significant given the low rate (3/82, 4%) of a positive Breslau-7 score of ≥4 (indicating concern for posttraumatic stress disorder).

Conclusion:

Use of the SNOO bassinet as a neonatal sleep intervention did not result in improved maternal mood at 6 weeks postpartum in our cohort of individuals with HDP. Self-reported mood was not associated with blood pressure in this cohort of individuals with HDP.
