Factors associated with postpartum psychiatric disorders using routine administrative data

Abstract Objective: To evaluate factors associated with postpartum psychiatric disorders and to propose a new approach for the use of routine mental health service data in BrazilMethods: We extracted data on visits to psychiatric outpatient services from the Authorization of Outpatient Procedures in Brazil (2008-2012). Generalized Additive Models for Location, Scale, and Shape (GAMLSS) with double Poisson distribution were performed, with postpartum psychiatric disorders as the dependent variable.Results: At each increment in the maternal age unit and CAPS coverage percentage, there was an increase of 1.01 (p<0.001) in the occurrence of postpartum psychiatric disorders.Conclusions: An increase in age is associated with a higher risk of presenting a postpartum psychiatric disorder. This approach provides an innovative feature to routinely analyse collected data.
