Women with polycystic ovary syndrome associated with increased anxiety risk: A population-based cohort study in Taiwan.

Background: Polycystic ovary syndrome (PCOS) has been associated with developing mental disorders in Western populations, but this association is poorly studied in Asians. Hence, using insurance claims data, this study evaluated the anxiety risk in women with PCOS.

Methods: Using Taiwan's National Health Insurance Research Database, we identified 7026 women aged 15-49 years with newly diagnosed PCOS without anxiety in 1998-2013 as the PCOS cohort.
