OBJECTIVE: To assess the strength of the relationships between serum carotenoids and three self-reported dietary intake instruments often used to characterize carotenoid intake in studies of diet and disease.<\/p>\n
DESIGN: Participants completed a Diet History Questionnaire (DHQ), two 24 h dietary recalls (24HR), a fruit and vegetable screener and a fasting blood draw. We derived dietary intake estimates of α-carotene, β-carotene, cryptoxanthin, lutein, zeaxanthin and lycopene from each diet instrument and calculated sex-specific multivariate correlations between dietary intake estimates and their corresponding serum values.<\/p>\n
SETTING: Montgomery County, Maryland, USA.<\/p>\n
SUBJECTS: Four hundred and seventy women and men aged 40-69 years in the National Cancer Institute’s Observing Protein and Energy Nutrition (OPEN) Study.<\/p>\n
RESULTS: Serum carotenoids correlated more strongly with the DHQ (r = 0\u00b734-0\u00b754 for women; r = 0\u00b738-0\u00b756 for men) than with the average of two recalls (r = 0\u00b726-0\u00b747 for women; r = 0\u00b726-0\u00b740 for men) with the exception of zeaxanthin, for which the correlations using recalls were higher. With adjustment for within-person variation, correlations between serum carotenoids and recalls were greatly improved (r = 0\u00b738-0\u00b783 for women; r = 0\u00b742-0\u00b774 for men). In most cases, correlations between serum carotenoids and the fruit and vegetable screener resembled serum-DHQ correlations.<\/p>\n
CONCLUSIONS: Evidence from the study provides support for the use of the DHQ, a fruit and vegetable screener and deattenuated recalls for estimating carotenoid status in studies without serum measures, and draws attention to the importance of adjusting for intra-individual variability when using recalls to estimate carotenoid values.<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-36836","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"Applied Research Program, Division of Cancer Control and Population Sciences, National Cancer Institute, 6130 Executive Blvd, EPN 4017A, Bethesda, MD 20892, USA.\r\n\r\n","annee":"2012","mois":"1","numero":"","page":"1-8","auteurs":[{"ID":36835,"post_author":"0","post_date":"2018-12-04 01:07:24","post_date_gmt":"2018-12-04 00:07:24","post_content":"","post_title":"Midthune","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"midthune","to_ping":"","pinged":"","post_modified":"2018-12-04 01:07:24","post_modified_gmt":"2018-12-04 00:07:24","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/midthune\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":14578,"post_author":"0","post_date":"2018-12-03 19:11:24","post_date_gmt":"2018-12-03 18:11:24","post_content":"","post_title":"Frances E Thompson","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"frances-e-thompson","to_ping":"","pinged":"","post_modified":"2018-12-03 19:11:24","post_modified_gmt":"2018-12-03 18:11:24","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/frances-e-thompson\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":19451,"post_author":"0","post_date":"2018-12-03 20:21:23","post_date_gmt":"2018-12-03 19:21:23","post_content":"","post_title":"Stephanie M George","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"stephanie-m-george","to_ping":"","pinged":"","post_modified":"2018-12-03 20:21:23","post_modified_gmt":"2018-12-03 19:21:23","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/stephanie-m-george\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"}],"sources":[{"ID":31458,"post_author":"0","post_date":"2018-12-03 23:45:23","post_date_gmt":"2018-12-03 22:45:23","post_content":"","post_title":"PUBLIC HEALTH NUTR","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"public-health-nutr-2","to_ping":"","pinged":"","post_modified":"2018-12-03 23:45:23","post_modified_gmt":"2018-12-03 22:45:23","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/source\/public-health-nutr-2\/","menu_order":0,"post_type":"source","post_mime_type":"","comment_count":"0","filter":"raw"}]},"yoast_head":"\n
