Abstract
Objective: The aim was to evaluate the prevalence of postpartum complications, including depression, in new mothers who had juvenile idiopathic arthritis (JIA) and to assess whether these differ from mothers who never had JIA. Methods: Our cohort study used data from physician billing and hospitalizations covering Quebec, Canada. We identified females with JIA with a first-time birth between 1 January 1983 and 31 December 2010 and assembled a control cohort of first-time mothers without JIA from the same administrative data, matching 4:1 for date of first birth, maternal age and area of residence. We compared the following postpartum complications: major puerperal infection, anaesthetic complications, postpartum haemorrhage, thromboembolism, obstetrical trauma, complications of obstetrical surgical wounds and maternal depression in the first year after delivery, in the JIA vs non-JIA groups, using bivariate analysis and multiple logistic regression. Results: The mean age at delivery was 24.7 years in the JIA group (n = 1681) and 25.0 years for the non-JIA group (n = 6724). Mothers with JIA were more likely to experience complications attributable to anaesthetic [adjusted risk ratio (aRR) 2.17, 95% CI; 1.05, 4.48], postpartum haemorrhage (aRR = 2.75, 95% CI: 2.42, 3.11) and thromboembolism (aRR = 5.27, 95% CI: 1.83, 15.17) but were at lower risk for obstetrical trauma (aRR = 0.78, 95% CI: 0.64, 0.95) or newly to develop depression in the first year postpartum (aRR = 0.52, 95% CI: 0.40, 0.68). Conclusion: Mothers with JIA appear to be at higher risk for complications attributable to anaesthesia, postpartum haemorrhage and thromboembolism. Prevention strategies for postpartum haemorrhage and thromboembolism may be especially important in this population.
