Our objective was to examine serum concentrations of these nutrients and compounds in a sample of 285 healthy participants, 12-17 y old, from three U.S. cities. Pearson correlations between diet measured with a food frequency questionnaire and serum nutrient concentrations among these adolescents (adjusted for total serum cholesterol, age, sex, race and body mass index) were as follows: retinol, 0.23; alpha -tocopherol, 0.16; alpha -carotene, 0.31; beta -carotene, 0.15; beta -cryptoxanthin, 0.38; lycopene, 0.08; and lutein + zeaxanthin, 0.25. Multivariate linear regression modeled associations of demographic, dietary and physiologic variables with serum concentrations of these nutrients. African-American participants had significantly lower concentrations of serum retinol (P &lt; 0.001), -tocopherol (P &lt; 0.01) and -carotene (P &lt; 0.02), but higher concentrations of lutein + zeaxanthin (P = 0.001) compared with Caucasians. Obese participants had serum nutrient concentrations that were 2-10% (P &lt; 0.05) lower than normal weight participants. Dietary intake was a significant predictor of all serum analytes (P &lt; 0.01) except lycopene. These models explained 20% of the variability in serum retinol, 28% of the variability in serum -tocopherol, and 14-24% of the variability in serum carotenoids.<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-56527","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"\"NEUHOUSER ML,FRED HUTCHINSON CANC
