Oxidative Balance Scores in Cancer Survivors: A Nationwide Cross-Sectional Study

Although some studies have investigated the relationship between oxidative imbalance and adverse outcomes, there is a lack of data on oxidative balance in cancer survivors. Using data of the 2013-2020 Korean nationwide surveys, this study examined the oxidative balance score (OBS) of non-survivors, short-term survivors (<5 years), and long-term survivors. Approximately 4.6% of the study subjects were cancer survivors, and of these, three-fifths were long-term survivors. Male and female short-term survivors had higher OBS than non-survivors, but the mean OBS of female long-term survivors was reversed. Physicians should periodically remind cancer survivors, particularly women, of the risks associated with unhealthy lifestyles.
