Valoración nutricional como complemento de los estudios en población expuesta a agentes oxidantes

Introduction: oxidative stress (OS) is associated with an imbalance between oxidation and antioxidant systems in favor to the former. The micronutrient dietary contribution could provide a protective effect against occupational exposure to oxidizing agents. The aim of this study was to determine the correlation between nutritional status, dietary and hygiene habits, macro and micronutrients intake and OS in a population exposed to oxidizing agents, compared with unexposed population. Material and methods: two populations with similar characteristics were studied, except for the work activity of one of them, constituted for people of both sexes, of 18-30 years old. Exposed Group consisted of 26 individuals working in photocopying and Unexposed Group by 27 volunteers who do not perform such work activity. A nutritional survey, two reminders of 24 hours, anthropometric measurements and biochemical parameters, and a determination of OS markers (Catalase, GSH / GSSG and TBARS) was performed. Results: to establish associations between variables, results were analyzed using multivariate statistics. Results show a positive correlation between work activity and oxidative imbalance and between high energy intake, low antioxidant micronutrients source intake, sedentary, altered lipid profile and OS. A positive relationship between low power intake, normal lipid profile and adequate fruits and vegetables intake with a normal oxidative state was show. Conclusions: Results show that changes in hygiene and dietary habits may provide protection to individuals exposed to oxidizing agents.
