Sleep and its association with depressive and anxiety symptoms during the last weeks of pregnancy: A population-based study.

Objective: To evaluate the association between sleep characteristics and depressive and anxiety symptoms during the immediate postpartum period.

Methods: People who had hospital births during 2019 in the municipality of Rio Grande (southern Brazil) were assessed with a standardized questionnaire concerning sociodemographic (eg, age and self-reported skin color) and health-related variables (eg, parity and stillbirth) (n = 2314) 24-48 hours after birth. We used the Munich Chronotype Questionnaire to assess sleep latency, inertia, duration, and chronotype; the Edinburgh Postpartum Depression Scale for depressive symptoms; and the General Anxiety Disorder 7-Item Scale to evaluate anxiety symptoms.
