Correlation between actual nutrition and lipid peroxidation and antioxidant defense parameters in aged 14–17 years adolescents living in rural area

The aim of the study was to reveal relationship between parameters actual nutrition and lipid peroxidation antioxidant defense system in adolescents aged 14–17 a rural area. Material methods. 76 Irkutsk region were examined by cross-sectional method. Actual studied 24-hour reproduction content substrates with unsaturated double bonds (DB), diene conjugates (DC), ketodienes conjugated trienes (KD CT), thiobarbituric acid reacting species (TBARS), α-tocopherol, retinol, reduced (GSH) oxidized glutathione (GSSG), total blood activity (TAA), superoxide dismutase (SOD) spectrophotometry fluorometry methods analyzed. Results. adolescents’ diet did not meet principles balanced – there protein intake, an imbalance fatty acids, A, C, D, B vitamins deficiency. An excessive element sodium. DB, KD CT TBARS increased significantly group adolescents, concentration DC decreased. Parameters both decreased (TAA, retinol content) (α-tocopherol, GSH concentration). Correlation analysis showed relationships DB vitamin B1, B2 content; level calories, carbohydrate B1 fats, TAA A β-carotene level; α-tocopherol E food; K; SOD H content. Multiple negative correlations GSSG fat, B9, K food found. Conclusions. calculated consumption indicators allow nutritional deviations connect them real provision body these metabolites.
