Different study designs and their respective sampling methodology utilized to estimate food consumption patterns can significantly alter the parameter estimates and the variability in the values obtained. This study investigated the impacts of study design on overall estimates of dietary intake by applying the temporal sampling characteristics used in cross-sectional approaches, as in The Continuing Survey of Food for Intakes by Individuals (CSFII), to food consumption data collected in a longitudinal manner via a bootstrap sampling technique. We examined the precision of time-averaged dietary intake estimates under various sampling schemes and explored the contribution of seasonality toward the dietary patterns. A comparison between the estimates of food consumption obtained from the bootstrap replicates and the longitudinal study estimates indicate that variability is significantly decreased when employing a longitudinal study design. Moreover, both between and within-subject variability decreases when individuals are followed over an increasing number of days. Finally, within the longitudinal study cohort, we observed a seasonal component to dietary intake for fruits and grains. Our findings suggest that longitudinal dietary surveys offer substantial improvements for exposure assessment compared to a standard cross-sectional design.<\/p>\n<p>PMID: 16908016 [PubMed &#8211; indexed for MEDLINE]\n","protected":false},"template":"","mots_cles":[],"class_list":["post-47021","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"Department of Environmental and Occupational Health, Rollins School of Public Health, Emory University, Atlanta, GA 30322, USA.","annee":"2006","mois":"8","numero":"103-3","page":"325-30","auteurs":[{"ID":28046,"post_author":"0","post_date":"2018-12-03 23:01:29","post_date_gmt":"2018-12-03 22:01:29","post_content":"","post_title":"Marjory L Givens","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"marjory-l-givens","to_ping":"","pinged":"","post_modified":"2018-12-03 23:01:29","post_modified_gmt":"2018-12-03 22:01:29","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/marjory-l-givens\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":43331,"post_author":"0","post_date":"2018-12-04 03:05:19","post_date_gmt":"2018-12-04 02:05:19","post_content":"","post_title":"Akbulut","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"akbulut-2","to_ping":"","pinged":"","post_modified":"2018-12-04 03:05:19","post_modified_gmt":"2018-12-04 02:05:19","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/akbulut-2\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":47020,"post_author":"0","post_date":"2018-12-04 04:10:52","post_date_gmt":"2018-12-04 03:10:52","post_content":"","post_title":"Bartell","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"bartell","to_ping":"","pinged":"","post_modified":"2018-12-04 04:10:52","post_modified_gmt":"2018-12-04 03:10:52","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/bartell\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":40536,"post_author":"0","post_date":"2018-12-04 02:16:02","post_date_gmt":"2018-12-04 01:16:02","post_content":"","post_title":"Pearson","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"pearson-2","to_ping":"","pinged":"","post_modified":"2018-12-04 02:16:02","post_modified_gmt":"2018-12-04 01:16:02","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/pearson-2\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"}],"sources":[{"ID":43451,"post_author":"0","post_date":"2018-12-04 03:07:14","post_date_gmt":"2018-12-04 02:07:14","post_content":"","post_title":"ENVIRON RES","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"environ-res","to_ping":"","pinged":"","post_modified":"2018-12-04 03:07:14","post_modified_gmt":"2018-12-04 02:07:14","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/source\/environ-res\/","menu_order":0,"post_type":"source","post_mime_type":"","comment_count":"0","filter":"raw"}]},"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v23.6 (Yoast SEO v23.6) -
