  • Background: Research regarding the correlation betweenobesity and oxidative stress is important due to the healthcomplications they entail and elucidating this associationthrough the waist-to-height ratio is of great interest becauseit is an important anthropometric indicator of cardiovascularand metabolic diseases’ risk associated with obesity. The aimof this study was to gain a better understanding of the asso-ciation between waist-to-height ratio and total antioxidant ca-pacity and malondialdehyde values in adults. Methods: A cross-sectional population-based study wasconducted in 265 individuals from a municipality in north-eastern Brazil. Epidemiological data were collected, and an-thropometric and biochemical evaluations were performed. Toachieve the objectives proposed by the study, linear regres-sion was performed. Results: In the total sample, more than half of the partic-ipants were overweight or obese. The mean value of 54 cm(SD±10) waist-to-height ratio, with the majority of adults(65.28%) presenting with slight elevation waist-to-height ra-tio. A correlation was found between waist-to-height ratio andBMI with the values of total antioxidant capacity (t= -2.96;p=0.003) and malondialdehyde (t=2.87, p=0.004), as well asLDL (t=3.19, p=0.002), triglycerides (t=3.17; p=0.002). Conclusion: Abdominal obesity, reflected by a slight ele-vation in the waist-to-height ratio, corroborated by BMI wasindicated as an aggravating factor in oxidative stress increasebecause it was positively related with malondialdehyde valuesand negatively with total antioxidant capacity values in thisadult population
