Peripartum depression in parents with multiple sclerosis and psychiatric disorders in children
Abstract
Background: Although many individuals with multiple sclerosis (MS) experience depression, there are no studies on the frequency and effect of peripartum depression among parents with MS.
Objective: To examine the frequency of peripartum depression in individuals with MS and its potential association with children's psychiatric disorders.
Methods: We conducted a cohort study in British Columbia, Canada, using linked health databases, of parents with MS and their children, and age-matched unaffected parent-child dyads. The diagnosis of peripartum depression, MS and psychiatric disorders in children was based on information from hospital admission, physician visit and drug prescription claims.
Results: Peripartum depression was significantly more common among MS parents (n = 360) versus unaffected (n = 1207) parents (25.8% vs 18.5%, p value 0.02), especially among MS affected fathers versus unaffected fathers (25.7% vs 10.2%, p value < 0.001). The incidence of psychiatric disorders in children was 3.3 and 2.7 per 100 child-years among children with and without an MS parent, respectively. The rate of psychiatric disorders was significantly higher in children with an MS parent (vs without, hazard ratio (HR): 1.34; 95% confidence interval (CI): 1.03-1.74) and among children with parents who had peripartum depression (HR: 1.87; 95% CI: 1.36-2.55).
Conclusion: Parental MS is associated with a higher risk of peripartum depression and increases the risk of psychiatric disorders in children.
