Symptoms of Obsessive-Compulsive Disorder during Pregnancy and the Postpartum Period: a Systematic Review and Meta-Analysis

Abstract

The main aim of this systematic review and meta-analysis was to calculate and compare the frequencies of obsessions and compulsions in women with obsessive-compulsive disorder (OCD) during pregnancy (OCD-P), the postpartum period (OCD-PP) and when they are neither pregnant nor postpartum (OCD-NPP). Fourteen studies were selected after applying the inclusion and exclusion criteria. The meta-analysis showed that aggressive obsessions were much more common in OCD-PP than in OCD-P and OCD-NPP and that washing/cleaning compulsions were less frequent in OCD-PP than in OCD-P and OCD-NPP. These differences were significant, whereas the frequencies of various obsessions and compulsions did not distinguish between OCD-P and OCD-NPP. Obsessions about accidental harm to the infant and other infant-focused obsessions, checking compulsions, self-reassurance and seeking reassurance from others were also relatively common in OCD-PP. Clinical manifestations of OCD-PP are relatively specific and differ from those of OCD-P and OCD-NPP, whereas OCD-P does not seem to have distinct clinical features. Although these findings do not necessarily suggest that OCD-PP is a distinct subtype of OCD, they have important conceptual and clinical implications.
