Sleep disturbance is a universal experience during the pregnancy and postpartum periods. Sleep disturbance is linked to a range of negative consequences. Literature shows that cognitive behavioural Therapy for Insomnia (CBT-I) is an effective treatment, with comparable short-term and superior long-term effects to sleep medication alone. The aim of this study was to evaluate the short-, medium-, and long-term efficacy of a non-pharmacological sleep intervention in the perinatal periods. The study was a longitudinal randomised controlled trial based on the SEED (Sleep Eat Emotions and Development) project which was a two-arm, parallel-group, single-blind, superiority randomised controlled trial. Participants were pregnant women enrolled in Childbirth Education and were randomised 1:1 to the intervention or a comparison condition. Results showed that compared to receiving an attention- and time-matched control, receiving a cognitive behavioural sleep intervention was associated with lower symptoms of insomnia, sleep disturbance, and sleep-related impairment during late pregnancy. Moreover, the intervention had long-term benefits to gestational parents’ sleep at 2-year postpartum. Authors conclude that a scalable cognitive behavioural sleep intervention, tailored for the perinatal periods, is feasible, acceptable, and efficacious in buffering against the natural increase in sleep complaints during the 3rd trimester.
BACKGROUND
Sleep disturbance is common in gestational parents during pregnancy and postpartum periods. This study evaluated the feasibility and efficacy of a scalable cognitive behavioural therapy (CBT) sleep intervention tailored for these periods.
METHODS
This is a two-arm, parallel-group, single-blind, superiority randomised controlled trial. Nulliparous females without severe medical/psychiatric conditions were randomised 1:1 to CBT or attention- and time-matched control. All participants received a 1 h telephone session and automated multimedia emails from the third trimester until 6 months postpartum. Outcomes were assessed with validated instruments at gestation weeks 30 (baseline) and 35 (pregnancy endpoint), and postpartum months 1.5, 3, 6 (postpartum endpoint), 12 and 24.
RESULTS
In total, 163 eligible participants (age M ± s.d. = 33.35 ± 3.42) were randomised. The CBT intervention was well accepted, with no reported adverse effect. Intention-to-treat analyses showed that compared to control, receiving CBT was associated with lower insomnia severity and sleep disturbance (two primary outcomes), and lower sleep-related impairment at the pregnancy endpoint ( values ⩽ 0.001), as well as at 24 months postpartum ( ranges 0.012-0.052). Group differences across the first postpartum year were non-significant. Participants with elevated insomnia symptoms at baseline benefitted substantially more from CBT ( control), including having significantly lower insomnia symptoms throughout the first postpartum year. Group differences in symptoms of depression or anxiety were non-significant.
CONCLUSIONS
A scalable CBT sleep intervention is efficacious in buffering against sleep disturbance during pregnancy and benefitted sleep at 2-year postpartum, especially for individuals with insomnia symptoms during pregnancy. The intervention holds promise for implementation into routine perinatal care.
