Abstract [en]

BACKGROUND: This study examined the association between a single nucleotide polymorphism in the hydroxysteroid (11-beta) dehydrogenase 1 gene and neuroticism, as well as the possible mediatory role of neuroticism in the association between the polymorphism and postpartum depressive symptoms.

METHODS: 769 women received questionnaires containing the Edinburgh Postnatal Depression Scale (EPDS) at six weeks postpartum and demographic data at pregnancy week 17 and 32 and at six weeks postpartum, as well as the Swedish universities Scales of Personality at pregnancy week 32.

RESULTS: Linear regression models showed an association between the GG genotype and depressive symptoms. When neuroticism was introduced in the model, it was associated with EPDS score, whereas the association between the GG genotype and EPDS became borderline significant. A path analysis showed that neuroticism had a mediatory role in the association between the polymorphism and EPDS score.

LIMITATIONS: The use of the EPDS, which is a self-reporting instrument.

CONCLUSIONS: Neuroticism was associated with the polymorphism and had a mediatory role in the association between the polymorphism and postpartum depression. This finding elucidates the genetic background of neuroticism and postpartum depression.
