Obesity is a substantial health problem in the United States, and is associated with many chronic diseases. Previous studies have linked poor dietary habits to obesity. This cross-sectional study aimed to identify the association between body mass index (BMI) and fast-food consumption among 669 same-sex adult twin pairs residing in the Puget Sound region around Seattle, Washington. We calculated twin-pair correlations for BMI and fast-food consumption. We next regressed BMI on fast-food consumption using generalized estimating equations (GEE), and finally estimated the within-pair difference in BMI associated with a difference in fast-food consumption, which controls for all potential genetic and environment characteristics shared between twins within a pair. Twin-pair correlations for fast-food consumption were similar for identical (monozygotic; MZ) and fraternal (dizygotic; DZ) twins, but were substantially higher in MZ than DZ twins for BMI. In the unadjusted GEE model, greater fast-food consumption was associated with larger BMI. For twin pairs overall, and for MZ twins, there was no association between within-pair differences in fast-food consumption and BMI in any model. In contrast, there was a significant association between within-pair differences in fast-food consumption and BMI among DZ twins, suggesting that genetic factors play a role in the observed association. Thus, although variance in fast-food consumption itself is largely driven by environmental factors, the overall association between this specific eating behavior and BMI is largely due to genetic factors.<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-26401","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"Department of Epidemiology,School of Public Health,University of Washington,Seattle,WA,USA.","annee":"2015","mois":"5","numero":"","page":"","auteurs":[{"ID":26397,"post_author":"0","post_date":"2018-12-03 22:37:46","post_date_gmt":"2018-12-03 21:37:46","post_content":"","post_title":"Glen E Duncan","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"glen-e-duncan","to_ping":"","pinged":"","post_modified":"2018-12-03 22:37:46","post_modified_gmt":"2018-12-03 21:37:46","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/glen-e-duncan\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":26398,"post_author":"0","post_date":"2018-12-03 22:37:46","post_date_gmt":"2018-12-03 21:37:46","post_content":"","post_title":"Hannah Cohen-Cline","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"hannah-cohen-cline","to_ping":"","pinged":"","post_modified":"2018-12-03 22:37:46","post_modified_gmt":"2018-12-03 21:37:46","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/hannah-cohen-cline\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":25427,"post_author":"0","post_date":"2018-12-03 22:19:54","post_date_gmt":"2018-12-03 21:19:54","post_content":"","post_title":"Anne Vernez Moudon","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"anne-vernez-moudon","to_ping":"","pinged":"","post_modified":"2018-12-03 22:19:54","post_modified_gmt":"2018-12-03 21:19:54","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/anne-vernez-moudon\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":26399,"post_author":"0","post_date":"2018-12-03 22:37:47","post_date_gmt":"2018-12-03 21:37:47","post_content":"","post_title":"Richard Lau","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"richard-lau","to_ping":"","pinged":"","post_modified":"2018-12-03 22:37:47","post_modified_gmt":"2018-12-03 21:37:47","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/richard-lau\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":26400,"post_author":"0","post_date":"2018-12-03 22:37:48","post_date_gmt":"2018-12-03 21:37:48","post_content":"","post_title":"Eric Turkheimer","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"eric-turkheimer","to_ping":"","pinged":"","post_modified":"2018-12-03 22:37:48","post_modified_gmt":"2018-12-03 21:37:48","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/eric-turkheimer\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"}],"sources":[{"ID":17699,"post_author":"0","post_date":"2018-12-03 19:55:29","post_date_gmt":"2018-12-03 18:55:29","post_content":"","post_title":"Twin research and human genetics : the official journal of the International Society for Twin Studies","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"twin-research-and-human-genetics-the-official-journal-of-the-international-society-for-twin-studies","to_ping":"","pinged":"","post_modified":"2018-12-03 19:55:29","post_modified_gmt":"2018-12-03 18:55:29","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/source\/twin-research-and-human-genetics-the-official-journal-of-the-international-society-for-twin-studies\/","menu_order":0,"post_type":"source","post_mime_type":"","comment_count":"0","filter":"raw"}]},"yoast_head":"\n
