Abstract

Objective:  To examine the association between first hospital admissions due to postpartum psychosis and the explanatory variables age, educational level, marital status and year of delivery.

Method:  All Swedish first-time mothers (n = 502 767) were included during a 12-year period and followed for first hospital admissions due to postpartum psychosis. Cox regression was used to estimate hazard ratios, adjusted for the explanatory variables.

Results:  Older age and being a single mother implied an increased risk of first hospital admissions due to postpartum psychosis among first-time mothers. Educational level was not associated with first hospital admissions due to postpartum psychosis. During the 1990s, when a reduction in psychiatric beds occurred, first hospital admissions due to postpartum psychosis decreased significantly.

Conclusion:  Certain sociodemographic factors are associated with first hospital admissions due to postpartum psychosis. Untreated postpartum psychosis due to fewer psychiatric beds could have hazardous effects on mothers and their children.
