Objective: To examine the effects of different predictors on the incidence and severity of postpartum depression
(PPD) symptoms in a Thai population.
Methods: In this case control study we delineate the clinical, demographic and socio-economic risk factors
associated with PPD symptoms. We used the Edinburgh Postnatal Depression Scale (EPDS) 4–6 weeks
postpartum to divide parturients into those with (n = 53) and without (n = 260) PPD using a cutoff score
of 11.
