Abstract excerpt

OBJECTIVE: Postpartum depression (PPD) is a common but severe psychiatric condition following childbirth, and its underlying causes and degree of heritability remain unclear. We aimed to examine the heritability of PPD among parous female twin pairs. METHOD: We linked data from the Danish Twin Register to nationwide health registers. Zygosity was defined as monozygotic (MZ) or dizygotic (DZ) based on validated...
