Background: Antenatal depression is associated with several adverse maternal outcomes, perinatal outcomes, lower academic achievements in adolescence, and future mental health problems for the mothers. Early identification and effective treatment of depression in antenatal women can also improve perinatal outcomes. Aim: This study aims to understand the prevalence of antenatal depression and anxiety disorder, along with associated factors, among antenatal women attending the outpatient clinic of the obstetrics department in a tertiary care hospital. Methods: A cross-sectional design was employed for determining the prevalence, while a case-control framework was used for analysis of the associated factors. Semi-structured sociodemographic pro forma, Patient Health Questionnaire (PHQ-9) Tamil version, and Generalised Anxiety Disorder (GAD-7) Tamil version were administered to antenatal women after obtaining informed consent. Those who scored above 10 points on the PHQ-9 or above 9 points on the GAD-7 were interviewed using the Mini-International Neuropsychiatric Interview (MINI) diagnostic interview schedule, by a psychiatrist, for confirming the diagnosis. Results: In our sample, 22% of the participants were diagnosed with depression, and 23% with generalized anxiety disorder (GAD). Twenty-eight participants (13.4%) had both depression and GAD. Antenatal depression was associated with alcohol use in the spouse (P < 0.015), physical violence (P < 0.026), low perceived social support from the in-laws (P < 0.039), and pressure to have a male child (0.001). Antenatal GAD was associated with low perceived social support from the in-laws (P < 0.039) and pressure to have a male child (P < 0.041). Conclusion: The occurrence of depression and generalized anxiety disorder is high in antenatal women. Our study identified relevant psychosocial factors that may be potential targets to develop effective interventions.
