It was hypothesised that participant characteristics moderate intervention effect on weight change and improved eating and physical activity behaviours during the 3-month program mediate the relationship between intervention and weight.<\/p>\n<p style=\"text-align:justify\"><strong>METHODS<\/strong><br \/>\nIn our randomised controlled trial, young adults at risk of weight gain (n&thinsp;=&thinsp;250) were assigned either to an intervention group that received a 3-month mHealth (TXT2BFiT) program with 6-month maintenance or to a control group. Data were collected via online self-report surveys. Hypothesised moderators and mediators of the intervention effect on weight were independently assessed in PROCESS macro models for 3 and 9-month weight change.<\/p>\n<p style=\"text-align:justify\"><strong>RESULTS<\/strong><br \/>\nMales (P&thinsp;=&thinsp;0.01), mid-20s age group (P&thinsp;=&thinsp;0.04), and higher income earners (P&thinsp;=&thinsp;0.02) moderated intervention effects on weight change at 3-months and males only at 9-months (P&thinsp;=&thinsp;0.02). Weight change at 3 (-1.12&nbsp;kg) and 9-months (-1.38&nbsp;kg) remained significant when 3-month nutrition and physical activity behaviours were specified as mediators (P &lt;0.01 and P&thinsp;=&thinsp;0.01 respectively). Indirect paths explained 39&nbsp;% (0.72\/1.85&nbsp;kg) and 40&nbsp;% (0.92\/2.3&nbsp;kg) of total effect on weight change at 3 and 9-months respectively. Increased vegetable intake by intervention group at 3-months accounted for 19 and 17&nbsp;% and decreased sugar-sweetened beverages accounted for 8 and 13&nbsp;% of indirect weight change effects at 3 and 9-months respectively.<\/p>\n<p style=\"text-align:justify\"><strong>CONCLUSIONS<\/strong><br \/>\nTXT2BFiT was effective for both young men and women. Small sustained behavioural changes, including increased vegetable intake and decreased sugar-sweetened beverages consumption significantly mediated the intervention&#039;s effects on weight change. Improved eating behaviours and increased physical activity accounted for approximately 40&nbsp;% of the weight change.<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-21238","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"School of Life and Environmental Sciences, Charles Perkins Centre, University of Sydney, Sydney, NSW, 2006, Australia. stephanie.partridge@sydney.edu.au.","annee":"2016","mois":"4","numero":"13:1","page":"44","auteurs":[{"ID":16772,"post_author":"0","post_date":"2018-12-03 19:43:04","post_date_gmt":"2018-12-03 18:43:04","post_content":"","post_title":"Philayrath Phongsavan","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"philayrath-phongsavan","to_ping":"","pinged":"","post_modified":"2018-12-03 19:43:04","post_modified_gmt":"2018-12-03 18:43:04","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/philayrath-phongsavan\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":21237,"post_author":"0","post_date":"2018-12-03 20:47:01","post_date_gmt":"2018-12-03 19:47:01","post_content":"","post_title":"Adrian E Bauman","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"adrian-e-bauman","to_ping":"","pinged":"","post_modified":"2018-12-03 20:47:01","post_modified_gmt":"2018-12-03 19:47:01","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/adrian-e-bauman\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":10304,"post_author":"0","post_date":"2018-12-03 18:20:55","post_date_gmt":"2018-12-03 17:20:55","post_content":"","post_title":"Kevin McGeechan","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"kevin-mcgeechan","to_ping":"","pinged":"","post_modified":"2018-12-03 18:20:55","post_modified_gmt":"2018-12-03 17:20:55","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/kevin-mcgeechan\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":2983,"post_author":"0","post_date":"2018-12-03 17:01:06","post_date_gmt":"2018-12-03 16:01:06","post_content":"","post_title":"Stephanie R Partridge","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"stephanie-r-partridge","to_ping":"","pinged":"","post_modified":"2018-12-03 17:01:06","post_modified_gmt":"2018-12-03 16:01:06","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/stephanie-r-partridge\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":20962,"post_author":"0","post_date":"2018-12-03 20:42:44","post_date_gmt":"2018-12-03 19:42:44","post_content":"","post_title":"Margaret Anne Allman-Farinelli","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"margaret-anne-allman-farinelli","to_ping":"","pinged":"","post_modified":"2018-12-03 20:42:44","post_modified_gmt":"2018-12-03 19:42:44","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/margaret-anne-allman-farinelli\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"}],"sources":[{"ID":1610,"post_author":"0","post_date":"2018-12-03 16:00:56","post_date_gmt":"2018-12-03 15:00:56","post_content":"","post_title":"The international journal of behavioral nutrition and physical activity","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"the-international-journal-of-behavioral-nutrition-and-physical-activity","to_ping":"","pinged":"","post_modified":"2018-12-03 16:00:56","post_modified_gmt":"2018-12-03 15:00:56","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/source\/the-international-journal-of-behavioral-nutrition-and-physical-activity\/","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) -
