ROZOWSKI N, Jaime et al. Differences in plasma antioxidants according to socioeconomic level in Chilean women. Rev. méd. Chile [online]. 2001, vol.129, n.1, pp.43-50. ISSN 0034-9887.

Background: Free radical-mediated oxidative damage is a known initial event in atherogenesis. Cardiovascular disease is frequent in the Chilean population showing differences in the prevalence of risk factors of the disease according to socioeconomic level (SEL). Aim: To determine levels of antioxidants and lipid peroxides in Chilean women from different SEL. Patients and methods: Blood samples were taken from 81 women for measurements of plasma ascorbic acid, ß-carotene, a-tocopherol, licopene, ubiquinol, glutathione, total plasma antioxidant capacity, and lipid peroxides (TBARS). Results: Individuals in the lower SEL showed reduced levels of plasma ß-carotene, ascorbic acid, a-tocopherol, and ubiquinol compared to women in the higher SEL. There were no differences between groups in the plasma levels of glutathione, total antioxidant capacity, or TBARS. Conclusions: The results could be explained in part by the higher consumption of fruits and vegetables in women from the upper SEL (Rev Méd Chile 2001; 129: 43-50)
