However, the influence of BMI on these associations has not been explored in detail. We explored in a cross-sectional study the relation between dietary carotenoid and vitamin C intakes, using a 135-item FFQ, with their plasma concentrations by BMI categories in 252 men and 293 women, 65 years and older. For men and women combined, significant (P&lt;0.05) Pearson correlations were observed between energy-adjusted dietary intakes and plasma concentrations (carotenoids adjusted for cholesterol) for: a-carotene 0.21, beta-carotene 0.19, lycopene 0.18, (beta-cryptoxanthin 0.20 and vitamin C 0.36. Multiple linear regression analyses showed that the intake of carotenoids and vitamin C were significant predictors of their respective plasma concentration (P&lt;0.01), and that BMI was inversely associated with plasma concentration of carotenoids (P &lt;= 0.01) but not with plasma vitamin C. In addition, we observed significant interactions between BMI and the intakes of a-carotene and lutein + zeaxanthin, and to a lower extent beta-carotene, suggesting that these intakes in subjects with high BMI were not good predictors of their plasma concentration. The present data suggest that plasma carotenoids and vitamin C may be good markers of dietary intake in elderly subjects, but not so for a-carotene, beta-carotene and lutein + zeaxanthin in obese subjects.<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-46840","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"Vioque J (reprint author), Univ Miguel
