Identifying risk factors for polycystic ovary syndrome in women with epilepsy: A comprehensive analysis of 248 patients.

To assess the risk factors for polycystic ovary syndrome (PCOS) in women with epilepsy (WWE) and develop a practical approach for PCOS screening based on clinical characteristic, blood indicator, and anti-seizure medication (ASM) profiles. This cross-sectional study was conducted with 248 WWE who were consecutively enrolled from the Epilepsy Center of West China Hospital between April 2021 and March 2022. The epilepsy characteristics, blood indicators, and use of ASMs were compared between WWE with and without PCOS. Multivariate logistic regression was used to identify the factors independently associated with PCOS. The differential analysis showed that younger age at onset of epilepsy (<13 years), a history of birth hypoxia, obesity (BMI ≥25 kg/m ), use of levetiracetam (LEV) (≥1 year), higher levels of cholesterol, luteinizing hormone (LH) and anti-Müllerian hormone (AMH), and lower levels of sex hormone-binding globulin were associated with PCOS (p < .05). Multivariate logistic regression identified that obesity (BMI ≥25 kg/m ), use of LEV (≥1 year), and higher levels of AMH and LH were independently associated with PCOS in WWE (p < .05). Obesity (BMI ≥25 kg/m ), LEV use (≥1 year), and elevated AMH and LH levels suggest an increased in the probability of occurrence of PCOS in WWE. The combination of these profiles provides a practical approach for screening PCOS in WWE.
