title: Plasma 3-nitrotyrosine, urinary 8-isoprostane and 8-OHdG among healthy Japanese people.
abstract: To examine the relation between lifestyle factors and oxidative stress biomarkers, this study analysed plasma 3-nitrotyrosine (3-NT), urinary 8-isoprostane and 8-hydroxy-2'- deoxyguanosine (8-OHdG) of 323 healthy Japanese without any disease. Plasma 3-NT was significantly increased by excessive exercise (p=0.010), but it was not significantly different in terms of sex, age (< 40, >==40), BMI (<18.5, 18.5-24.9, >==25.0), smoking (non-smokers, smokers) and alcohol drinking per week (non-drinkers, <10 units, >==10 units). Urinary 8-isoprostane was significantly associated with alcohol drinking (p <0.01) and sex (p <0.01), although it had no significant relevance to age and exercise. Moreover, urinary 8-OHdG was positively associated with age (p <0.05) and negatively associated with BMI (p <0.05) and fasting insulin (p <0.001). However, it was not related with sex, smoking, alcohol drinking and exercise. In conclusion, the present results suggest that 3-NT, 8-isoprostane and 8-OHdG seem to be useful biomarkers for early prediction of lifestyle-related disease risk at the population level.
