Recent study examined the heterogeneous progression, interrelationships, and predictive factors of perinatal insomnia and depression across the perinatal period. The researchers used group-based trajectory modeling to identify distinct trajectories of insomnia and depressive symptoms from early pregnancy to 6 months postpartum.
The results showed three distinct insomnia trajectories: a "no insomnia" group (27.7%), a "subclinical insomnia" group (54.5%), and a "clinical insomnia" group (17.8%). For depressive symptoms, three trajectories were also identified: a "low-stable" group (38.7%), a "moderate-stable" group (43.9%), and a "high-improving" group.
The dual trajectory analysis revealed significant interrelationships between insomnia and depression, with the severity of symptoms co-occurring. Women in the low-stable depression group predominantly had no insomnia, while those in the moderate-stable depression group mostly had subclinical insomnia, and the high-improving depression group had the highest rates of clinical insomnia.
Predictive Factors for Insomnia and Depression Trajectories
Baseline factors including anxiety scores ≥24, insomnia scores ≥8, and depression scores ≥10 were common predictors of both adverse insomnia and depression trajectories. However, social capital was not a significant predictor.
Implications and Recommendations for Integrated Interventions
These findings highlight the importance of integrated screening and treatment approaches that simultaneously address comorbid insomnia and depression during the perinatal period. Tailored interventions based on symptom trajectory profiles could help improve maternal mental health outcomes. Future research should further explore the temporal dynamics and underlying mechanisms linking these conditions.
Key Points
1. The study examined the heterogeneous progression, interrelationships, and predictive factors of perinatal insomnia and depression across the perinatal period using group-based trajectory modeling.
2. The results showed three distinct trajectories for both insomnia and depressive symptoms - a "no insomnia"/"low-stable" group, a "subclinical insomnia"/"moderate-stable" group, and a "clinical insomnia"/"high-improving" group.
3. The dual trajectory analysis revealed significant interrelationships between insomnia and depression, with the severity of symptoms co-occurring across the three trajectory groups.
4. Baseline factors including anxiety scores ≥24, insomnia scores ≥8, and depression scores ≥10 were common predictors of both adverse insomnia and depression trajectories, but social capital was not a significant predictor.
5. The findings highlight the importance of integrated screening and treatment approaches that simultaneously address comorbid insomnia and depression during the perinatal period.
6. Tailored interventions based on symptom trajectory profiles could help improve maternal mental health outcomes, and future research should further explore the temporal dynamics and underlying mechanisms linking these conditions.
