Oxidative Balance Scores in Adults with Suicidal Ideation: A Nationwide Korean Survey

This cross-sectional study investigated the relationship between oxidative balance (OB) scores and suicidal ideation among the Korean adults. Data from 17,753 adults with information on suicidal ideation and OB scores were analysed using four years of the nationwide survey. A stepwise multivariate logistic regression model was used to catch the factors associated with suicidal ideation, including depressive mood and OB scores. Approximately 5% of the participants had suicidal ideation. Low OB scores were significantly and independently associated with suicidal ideation, and this association was not influenced by depressive mood. In conclusion, oxidative imbalance was related to suicidal ideation, independent of depressive mood. Key Words: Depression, Oxidative stress, Population surveillance, Suicidal ideation.
