BackgroundMetformin is commonly prescribed to manage polycystic ovary syndrome (PCOS), which is one of the most common endocrine disorders among women of childbearing age and is associated with high prevalence rates of depression and anxiety.ObjectiveThis study's objective was to determine the impact of prescribed metformin on depression and anxiety levels of patients with PCOS.MethodsThis prospective, multi-center, cohort study examined the impact of prescribed metformin on the depression and anxiety of women with PCOS in four gynecology clinics in Saudi Arabia and Jordan. The women had recently been prescribed metformin along with lifestyle modifications, such as diet and exercise, and were compared to another group of women with PCOS who were prescribed lifestyle modifications only. Depression and anxiety were assessed at baseline and three months later using the Patient Health Questionnaire (PHQ-9) and the Generalized Anxiety Disorder (GAD-7) scale, respectively. Health-related quality of life was measured using the Short Form Health Survey (SF-36). Multiple logistic regression analyses were conducted to examine the impact of metformin on depression and anxiety.ResultsEighty-six women participated in the study: 53 were prescribed metformin with lifestyle modifications, and 33 were prescribed lifestyle modifications only. The women on metformin had 70% lower odds of having major depression (PHQ-9≥10) (OR=0.302, P=0.045); however, no significant effect of metformin on anxiety (GAD-7≥10) was found.ConclusionMetformin may have a role in the management of depression symptoms among patients with PCOS; however, its potential antidepressant effect should be further examined in randomized double-blind placebo-controlled clinical trials.© 2020 AlHussain et al.
