This study aimed to evaluate the association between oxidative balance score (OBS) and GC prevalence using data from the National Health and Nutrition Examination Survey (NHANES) 2011– 2018.Methods: A total of 7816 adult female participants were included, of whom 195 reported a history of GC (cervical, endometrial, or ovarian). OBS was computed from 20 components: 15 antioxidants and five pro-oxidants from dietary and lifestyle sources. Multivariable logistic regression models were used to estimate the odds ratios (ORs) and 95% confidence intervals (CIs) for GC according to the OBS tertiles and per-unit increases, adjusting for covariates.Results: Higher total OBS was associated with significantly lower odds of GC (adjusted OR per unit increase = 0.92; 95% CI: 0.86– 0.97). Participants in the highest OBS tertile had 34% lower odds of developing GC than those in the lowest tertile. This association was more pronounced among women aged ≥ 60 years, non-smokers, and those with normal body mass index (BMI).Conclusion: Greater antioxidant exposure, as reflected by higher OBS, was inversely associated with GC risk. These findings support dietary and lifestyle interventions aimed at improving oxidative balance. Keywords: oxidative stress, gynecologic neoplasms, diet, lifestyle, antioxidants
