However, these cross-sectional studies are unable to determine whether a high RRV of food is predictive of adiposity change or whether it is a consequence of being obese.<\/p>\n<p style=\"text-align: justify\"><strong>OBJECTIVE: <\/strong>The objective was to examine the association between the RRV of food and 1-y weight gain in children aged 7-10 y.<\/p>\n<p style=\"text-align: justify\"><strong>DESIGN:<\/strong> An observational longitudinal study design was used. The RRV of food was determined by using a questionnaire method at baseline when the children (n = 316) were aged 7-9 y. Adiposity [body mass index (BMI), BMI SD score, fat mass index, waist circumference, and waist circumference SD score] was assessed at baseline and after 1 y.<\/p>\n<p style=\"text-align: justify\"><strong>RESULTS:<\/strong> Regression analyses indicated that the RRV of food was not associated with any measure of adiposity at baseline or at the 1-y follow-up (all P &gt; 0.58). Changes in BMI (B = 0.06, P &lt; 0.001), BMI SD score (B = 0.03, P = 0.001), and fat mass index (B = 0.09, P = 0.001) after 1 y were significantly predicted by the RRV of food at baseline.<\/p>\n<p style=\"text-align: justify\"><strong>CONCLUSIONS: <\/strong>The RRV of food predicted the change in adiposity over a relatively short-term period of 1 y and thus may be associated with the development of obesity. The lack of association in cross-sectional analyses indicates that this behavior is a risk factor for weight gain, although weight differences may not emerge until later childhood.<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-42518","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"Department of Epidemiology and Public Health, University College London, London, United Kingdom, and the Institute of Psychological Sciences, University of Leeds, Leeds, United Kingdom.","annee":"2009","mois":"8","numero":"90:2","page":"276-81","auteurs":[{"ID":1778,"post_author":"0","post_date":"2018-12-03 16:02:30","post_date_gmt":"2018-12-03 15:02:30","post_content":"","post_title":"Laura Webber","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"laura-webber","to_ping":"","pinged":"","post_modified":"2018-12-03 16:02:30","post_modified_gmt":"2018-12-03 15:02:30","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/laura-webber\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":42517,"post_author":"0","post_date":"2018-12-04 02:51:00","post_date_gmt":"2018-12-04 01:51:00","post_content":"","post_title":"Saxton","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"saxton","to_ping":"","pinged":"","post_modified":"2018-12-04 02:51:00","post_modified_gmt":"2018-12-04 01:51:00","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/saxton\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":38590,"post_author":"0","post_date":"2018-12-04 01:39:54","post_date_gmt":"2018-12-04 00:39:54","post_content":"","post_title":"Hillier","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"hillier","to_ping":"","pinged":"","post_modified":"2018-12-04 01:39:54","post_modified_gmt":"2018-12-04 00:39:54","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/hillier\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"}],"sources":[{"ID":1720,"post_author":"0","post_date":"2018-12-03 16:01:56","post_date_gmt":"2018-12-03 15:01:56","post_content":"","post_title":"Am J Clin Nutr.","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"am-j-clin-nutr","to_ping":"","pinged":"","post_modified":"2018-12-03 16:01:56","post_modified_gmt":"2018-12-03 15:01:56","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/source\/am-j-clin-nutr\/","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) -
