However, significant opposition has been raised to their implementation.<\/p>\n<p><strong>Objective:<\/strong><\/p>\n<p>To examine (1) the percentages of US middle and high school students who currently attend schools that have specific components of the USDA standards; (2) evidence that the identified USDA standard components may be associated with student overweight\/obesity; and (3) evidence of sociodemographic differences in the observed associations.<\/p>\n<p><strong>Design, Setting, and Participants:<\/strong><\/p>\n<p>We used data from annual nationally representative cross-sectional studies of students and school administrators in US public middle and high schools from the 2007-2008 through 2011-2012 school years.<\/p>\n<p><strong>Exposures:<\/strong><\/p>\n<p>Administrator-reported school meal and competitive venue food and beverage availability.<\/p>\n<p><strong>Main Outcomes and Measures:<\/strong><\/p>\n<p>Body mass index and overweight\/obesity calculated from student self-reported height and weight.<\/p>\n<p><strong>Results:<\/strong><\/p>\n<p>Analytical samples included 22&thinsp;716 eighth grade students in 313 schools and 30&thinsp;596 tenth and 12th grade students in 511 schools. The mean student response rate was 86.5%; mean school administrator response rate, 83.1%. During the study period, 21.1% of middle school and 30.1% of high school students attended schools without any of the identified components; all 5 identified components were in schools attended by only 1.8% and 0.3% of middle school and high school students, respectively. No significant associations between standard components and self-reported overweight\/obesity were observed among middle school students overall. Among high school students, significantly lower odds of overweight\/obesity were associated with having fruits or vegetables available wherever foods were sold (adjusted odds ratio [AOR], 0.86 [95% CI, 0.77-0.96]; P&thinsp;=&thinsp;.009), the absence of milk with higher fat levels (AOR, 0.92 [95% CI, 0.85-1.00]; P&thinsp;=&thinsp;.04), and having 3 or more USDA standard components (AOR, 0.89 [95% CI, 0.79-1.00]; P&thinsp;=&thinsp;.04). A significant association between the absence of sugar-sweetened beverages and lower overweight\/obesity was found for Hispanic middle school students (AOR, 0.65 [95% CI, 0.51-0.82]; P&thinsp;&lt;&thinsp;.001) and nonwhite high school students (AOR, 0.80 [95% CI, 0.70-0.91]; P&thinsp;=&thinsp;.001).<\/p>\n<p><strong>Conclusions and Relevance:<\/strong><\/p>\n<p>Because only 2% of middle school and less than 1% of high school students attended schools with all 5 identified USDA standard components in place, full implementation has the potential to substantially improve school nutritional environments. Some USDA standard components were associated with a lower risk for student overweight\/obesity, especially for high school and nonwhite students.<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-30391","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"Institute for Social Research, University of Michigan, Ann Arbor.\r\npomalley@umich.edu","annee":"2014","mois":"11","numero":":","page":"","auteurs":[{"ID":30388,"post_author":"0","post_date":"2018-12-03 23:31:27","post_date_gmt":"2018-12-03 22:31:27","post_content":"","post_title":"Yvonne M Terry-McElrath","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"yvonne-m-terry-mcelrath","to_ping":"","pinged":"","post_modified":"2018-12-03 23:31:27","post_modified_gmt":"2018-12-03 22:31:27","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/yvonne-m-terry-mcelrath\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":30389,"post_author":"0","post_date":"2018-12-03 23:31:27","post_date_gmt":"2018-12-03 22:31:27","post_content":"","post_title":"Lloyd D Johnston","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"lloyd-d-johnston","to_ping":"","pinged":"","post_modified":"2018-12-03 23:31:27","post_modified_gmt":"2018-12-03 22:31:27","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/lloyd-d-johnston\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":30390,"post_author":"0","post_date":"2018-12-03 23:31:28","post_date_gmt":"2018-12-03 22:31:28","post_content":"","post_title":"Patrick M O'malley","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"patrick-m-omalley","to_ping":"","pinged":"","post_modified":"2018-12-03 23:31:28","post_modified_gmt":"2018-12-03 22:31:28","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/patrick-m-omalley\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"}],"sources":[{"ID":2314,"post_author":"0","post_date":"2018-12-03 16:54:24","post_date_gmt":"2018-12-03 15:54:24","post_content":"","post_title":"JAMA pediatrics","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"jama-pediatrics","to_ping":"","pinged":"","post_modified":"2018-12-03 16:54:24","post_modified_gmt":"2018-12-03 15:54:24","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/source\/jama-pediatrics\/","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) -
