Background: Pregnancy involves substantial physical and emotional changes, often leading to heightened stress levels for expecting mothers. The mental health of pregnant women is crucial for both their well-being and that of their unborn child, but unfortunately, has not received due attention by the antenatal caregivers. This requires the necessary awareness of and sensitivity to mental health issues by the obstetricians. Aim: The aim was to evaluate the prevalence of anxiety and depression in antenatal mothers and analyse their correlates. Material and Methods: This prospective study was carried out on 250 antenatal patients selected by purposive sampling, at a tertiary care center affiliated to a teaching institution. The focus was on finding the prevalence and various correlating factors of anxiety and depression during the antenatal period. The various scales used for assessing were the Edinburgh Postnatal Depression Scale (EDPS), Pregnancy Related Anxiety Questionnaire- Revised 2 (PRAQ-R2) for anxiety and Multidimensional Scale of Perceived Social Support (MPSS). Results: The age range of participants was 18-42 years, with majority being in the 21-29 year age group. Majority (97.2%) of the participants had some kind of formal education, were homemakers (76.40%), in the low-income group (74.00%) and were multigravida (59.60%). The.prevalence.of.depression.and anxiety in the study group was found to be Conclusion 39.60% and 69.60% respectively. 58.40% of the participants reported having a high social support. A statistically significant association was found between anxiety and/or depression with social support from immediate family like husband, in-laws and other extended family members and friends. Subjects with high social support had less anxiety and depression. A statistically significant association was also found between anxiety and level of education level, history of abortion and BMI of the patient. No significant association was found with age, occupation, parity, family income or unplanned pregnancy. Antenatal patients with no prior history of psychiatric illness had a high prevalence of depression and anxiety. There was a statistically significant relationship between both anxiety and depression and the level of social support from close family members and friends. Additionally, there was a significant association between the development of anxiety and factors such as education level, BMI, and history of previous abortions.
