Variation factors of plasma retinol, carotenoids and vitamin E, and particularly sex and alcohol consumption, were studied on a sample of 271 males and females aged between 18 and 45 years. For analysis needs two subsamples were constituted: I (males and females with alcohol consumption ≤43 g/day) and II (males only). Sex and level of alcohol intake were two independent variation factors of plasma retinol and carotenoids. Associated with triglyceride and cholesterol for I and with triglyceride and ponderal index for II, they explained 40% of the total variance of plasma retinol. For carotenoids, the other associated independent variables were cholesterol, vitamin A and energy intake (r2 = 23% of explained variance). And for plasma vitamin E, neither sex nor alcohol consumption was a significant predictor of the model, the only variation factors being plasma lipids and age for I (r2 = 37%) and the same parameters associated with ponderal index for II (r2 = 55%
