Correspondence of the NCI fruit and vegetable screener to repeat 24-H recalls and serum carotenoids in behavioral intervention trials
Date of Original Version
Five sites participating in the NCI Behavior Change Consortium administered the NCI Fruit and Vegetable Screener (FVS) and multiple, nonconsecutive 24-h dietary recall interviews (24HR) to 590 participants. Three sites also obtained serum carotenoids (n = 295). Participants were primarily female, ethnically diverse, and varied by age and education. Correlations between 24HR and FVS by site ranged from 0.31 (P = 0.07) to 0.47 (P < 0.01) in men and from 0.43 to 0.63 (P < 0.01) in women. Compared with 24HR, FVS significantly (P < 0.05) overestimated intake at 2 of 4 sites for men and all 4 sites for women. Differences in estimated total servings of fruits and vegetables/d ranged from 0.16 to 3.06 servings. On average, the FVS overestimated intake by 1.76 servings in men and 2.11 servings in women. Alternative FVS scoring procedures and a 1-item screener lowered correlations with 24HR as well as serum carotenoids but alternate scoring procedures generally improved estimations of servings. © 2008 American Society for Nutrition.
