We used linear mixed-effects models to examine longitudinally the association between snacking (none, low, medium, and high tertiles according to energy) and BMI z score in children aged 2-13 y at baseline, controlling for sex, urbanicity, parental education, physical activity, and foods consumed at meals (n = 2277 observations). We tested whether this association differed by baseline underweight, normal weight, or overweight\/obese.<\/p>\n<p style=\"text-align:justify\"><strong>RESULTS<\/strong><br \/>\nSnacking is prevalent in Chinese children, with fruit being the most common snack. Snacking was not associated with meaningful BMI z score changes in normal-weight children. However, in children who were underweight at baseline, snacking in the top tertiles was associated with increases in BMI z scores from 2006 to 2011 (+1.2 and +1.1 BMI z score units for ages 2-6 and 7-13 y, respectively) (P &lt; 0.05). In overweight\/obese 2- to 6-y-old children at baseline, being in the lowest snacking tertile was associated with declines in BMI z score (-3.3), whereas in overweight 7- to 13-y-old children, being in the top tertile of snacking was associated with the greatest decline in BMI z score (-2.1) (P &lt; 0.05). The direction and magnitude of associations did not vary regardless of adjustment for total energy intake.<\/p>\n<p style=\"text-align:justify\"><strong>CONCLUSIONS<\/strong><br \/>\nSnacking in China, dominated by fruit consumption, is associated with decreased BMI in overweight\/obese children and increased BMI in underweight children. More work will be needed to monitor this relation as Chinese diets continue to westernize.<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-20853","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"Department of Nutrition, University of North Carolina, Chapel Hill, NC; and. popkin@unc.edu","annee":"2016","mois":"6","numero":"146:6","page":"1268-75","auteurs":[{"ID":1119,"post_author":"0","post_date":"2018-12-03 15:56:30","post_date_gmt":"2018-12-03 14:56:30","post_content":"","post_title":"Barry M Popkin","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"barry-m-popkin","to_ping":"","pinged":"","post_modified":"2018-12-03 15:56:30","post_modified_gmt":"2018-12-03 14:56:30","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/barry-m-popkin\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":4446,"post_author":"0","post_date":"2018-12-03 17:17:32","post_date_gmt":"2018-12-03 16:17:32","post_content":"","post_title":"Lindsey Smith Taillie","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"lindsey-smith-taillie-2","to_ping":"","pinged":"","post_modified":"2018-12-03 17:17:32","post_modified_gmt":"2018-12-03 16:17:32","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/lindsey-smith-taillie-2\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":7936,"post_author":"0","post_date":"2018-12-03 17:54:29","post_date_gmt":"2018-12-03 16:54:29","post_content":"","post_title":"Dantong Wang","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"dantong-wang","to_ping":"","pinged":"","post_modified":"2018-12-03 17:54:29","post_modified_gmt":"2018-12-03 16:54:29","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/dantong-wang\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"}],"sources":[{"ID":1924,"post_author":"0","post_date":"2018-12-03 16:50:41","post_date_gmt":"2018-12-03 15:50:41","post_content":"","post_title":"The Journal of nutrition","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"the-journal-of-nutrition","to_ping":"","pinged":"","post_modified":"2018-12-03 16:50:41","post_modified_gmt":"2018-12-03 15:50:41","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/source\/the-journal-of-nutrition\/","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) -
