Introduction: Psychological problems are one of the primary concerns for pregnant women, and depression is the most prevalent mental health condition that a woman may experience during her pregnancy and the perinatal period anywhere in the world. Aims: The purpose of this research was to determine the correlation between the severity of depression experienced in the final trimester of pregnancy and the outcome of the pregnancy. Materials and Methods: The level of depression experienced during the third trimester was evaluated by means of descriptive research. Data were obtained from fifty pregnant mothers at Krishna Hospital in Karad, Maharashtra, using a straightforward random selection procedure in both the prenatal outpatient department and the postnatal ward. In order to obtain the responses, interviews were conducted with fifty pregnant women who were in their third trimester according to their EDD. The demographic information was gathered through the use of a structured questionnaire, and the level of depression was determined using the Hamilton Depression Rating Scale (HAM-D). The data were summarised and described using frequency, percentage, means, and standard deviation, and inferential statistics like the chi-square (2) test were used to determine whether or not there was a relationship between the variables. Result: The outcomes of the study indicate that a total of 9 mothers (18%) did not suffer from depression, 22 mothers (44%) did suffer from mild depression, 16 mothers (32%) did suffer from moderate depression, and 3 mothers (6%) did suffer from severe depression. It was found that there was a significant association between the level of depression and the type of delivery (p = 0.0141), that there was a significant association between the level of depression of the mother and the weight of the baby (p = 0.0149), but that there was no significant association between the weight of the baby and the type of delivery (p = 0.8765). Conclusion: The findings of the study indicated that pregnant women experience depression during their third trimester, which necessitates the quick attention of medical professionals so that the condition does not have an impact on the outcome of the pregnancy.
