Effect of Vitex agnus-castus on Depression of Postmenopausal Women: A Randomized Clinical Trial

Abstract

Background: During menopause, women undergo biological, social, and psychological changes and are sensitive to stressors, especially anxiety and depression. Decreased estrogen in postmenopausal women causes mood swings, especially depression and anxiety. Objectives: We aimed to determine the effect of the Vitex agnus-castus extract on depression in postmenopausal women referring to a bone density measurement center in Shiraz. Methods: In a randomized controlled tria1, 60 postmenopausal women were randomly divided into an intervention group and a control group. In the intervention group, the research units were assigned to two groups of Vitex agnus-castus tablets and placebo, using random permuted blocks with a block size from one to six for each eligible case. After three months, depression was evaluated by the Edinburg Postnatal Depression Scale (EPDS) in both groups. Then, the results were analyzed using the independent t-test for quantitative variables. The obtained data were analyzed by a statistician using SPSS21. Results: Based on the results, the two groups were homogeneous in terms of the level of education, occupation, and housing, and a significant decrease was observed in the mean depression score in the Agnugolgroup (P < 0.001). Conclusions: Because depression increases during menopause, it is recommended that it should be used as a supplement during menopause.
