%X BACKGROUND: Depression is a significant public health issue, closely associated with epilepsy and oxidative stress (OS). This study aims to explore the level of OS in patients with epilepsy and its relationship with moderate to severe depression (MSD).
METHODS: This cross-sectional study includes 10,819 participants aged 20-80 from the National Health and Nutrition Examination Survey (NHANES) database (2013-2020 pre-pandemic). Depression symptoms were assessed using the Patient Health Questionnaire-9 (PHQ-9), and epilepsy was diagnosed based on antiepileptic drug use in the past 30 days. The oxidative balance score (OBS) was calculated from dietary recall and lifestyle habits over the previous 24 h.
RESULTS: Compared to non-epileptic subjects, epileptic patients have a significantly higher prevalence of depression. Epileptic patients exhibit lower OBS and Dietary Oxidative Balance Scores (DOBS), while there is no significant difference in Lifestyle Oxidative Balance Scores (LOBS). Depressed patients show lower OBS, DOBS, and LOBS. The mediation model indicates that DOBS mediates 3.44 % of epilepsy-related MSD.
CONCLUSIONS: Epileptic patients exhibit significantly higher levels of OS and consume more pro-oxidant foods compared to the general population. However, their lifestyle habits do not differ significantly from those of the control group. Additionally, epileptic patients are at a higher risk of developing MSD. Although a pro-oxidant diet may be associated with epilepsy-mediated MSD, its mediating effect is relatively weak.
