Exploring the longitudinal relationships between poor sleep, sleep apnoea, and depression during pregnancy

Depressive symptoms in early pregnancy predicted poorer self-reported sleep quality in later pregnancy, but not the reverse. Treating depression early in pregnancy may improve subsequent sleep. Sleep apnoea and depression may require distinct management approaches. Persistent sleep issues in pregnant women with depression or depressive symptoms should prompt screening for underlying sleep disorders, with sleep-focused interventions or medication adjustments considered if none are identified.
