BACKGROUND<\/strong>
\nDespite many health benefits, children do not consume enough fruits and vegetables (F\/V). The Food Dudes program increases in-school F\/V consumption, but the cost of prizes might be an adoption barrier.<\/p>\n

OBJECTIVE<\/strong>
\nOur aim was to compare the effects of the Food Dudes program when prizes vs praise are used to reward F\/V consumption.<\/p>\n

DESIGN<\/strong>
\nWe conducted a randomized controlled trial with three groups (ie, prize, praise, and control). Schools were randomly assigned to groups while approximately equating the percentage of students qualifying for free or reduced-price lunch. F\/V consumption (lunch-tray photos) was assessed twice at pre-intervention and once after phase I, phase II, and at 6 months post-intervention, spanning approximately 11 months overall.<\/p>\n

PARTICIPANTS\/SETTING<\/strong>
\nIn total, 2,292 students attending six elementary schools participated, with 882, 640, and 770 in the prize, praise, and control groups, respectively.<\/p>\n

INTERVENTION<\/strong>
\nThe Food Dudes program was implemented over 4.5 months in all but the control schools. Two Food Dudes schools implemented the program with tangible prizes contingent on individual students' F\/V consumption (prize group); two schools implemented Food Dudes using teacher praise instead of prizes (praise group). Follow-up data were collected 6 months post-intervention.<\/p>\n

MAIN OUTCOME MEASURE<\/strong>
\nF\/V consumption was assessed by digital imaging of lunch trays.<\/p>\n

STATISTICAL ANALYSIS PERFORMED<\/strong>
\nLinear mixed-effects modeling, including sex, grade, and baseline consumption as covariates, was performed.<\/p>\n

RESULTS<\/strong>
\nStudents attending the Food Dudes schools consumed more F\/V than control schools after phase I, with larger differences in prize schools (92% difference) than praise schools (50% difference). After phase II, Food Dudes schools consumed 46% more F\/V than control schools, with no difference between prize and praise schools. At 6-month follow-up, only prize schools consumed more F\/V than control schools (0.12 cups more per child, 42.9% difference).<\/p>\n

CONCLUSIONS<\/strong>
\nSocial praise proved an inadequate substitute for tangible prizes within the Food Dudes program. Program-related increases in F\/V consumption decreased after the intervention, underscoring the need to develop low-cost, long-term interventions to maintain and make habitual consumption of recommended levels of F\/V.<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-24977","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"Schell Games , Pittsburgh, Pennsylvania. greg.madden@usu.edu","annee":"2015","mois":"8","numero":"","page":"","auteurs":[{"ID":13476,"post_author":"0","post_date":"2018-12-03 18:58:40","post_date_gmt":"2018-12-03 17:58:40","post_content":"","post_title":"Gregory J Madden","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"gregory-j-madden","to_ping":"","pinged":"","post_modified":"2018-12-03 18:58:40","post_modified_gmt":"2018-12-03 17:58:40","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/gregory-j-madden\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":9588,"post_author":"0","post_date":"2018-12-03 18:12:50","post_date_gmt":"2018-12-03 17:12:50","post_content":"","post_title":"Heidi J Wengreen","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"heidi-j-wengreen","to_ping":"","pinged":"","post_modified":"2018-12-03 18:12:50","post_modified_gmt":"2018-12-03 17:12:50","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/heidi-j-wengreen\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":13477,"post_author":"0","post_date":"2018-12-03 18:58:41","post_date_gmt":"2018-12-03 17:58:41","post_content":"","post_title":"Sheryl S Aguilar","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"sheryl-s-aguilar","to_ping":"","pinged":"","post_modified":"2018-12-03 18:58:41","post_modified_gmt":"2018-12-03 17:58:41","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/sheryl-s-aguilar\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":13478,"post_author":"0","post_date":"2018-12-03 18:58:41","post_date_gmt":"2018-12-03 17:58:41","post_content":"","post_title":"Brooke A Morrill","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"brooke-a-morrill","to_ping":"","pinged":"","post_modified":"2018-12-03 18:58:41","post_modified_gmt":"2018-12-03 17:58:41","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/brooke-a-morrill\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":24976,"post_author":"0","post_date":"2018-12-03 22:08:16","post_date_gmt":"2018-12-03 21:08:16","post_content":"","post_title":"Jamison D Fargo","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"jamison-d-fargo","to_ping":"","pinged":"","post_modified":"2018-12-03 22:08:16","post_modified_gmt":"2018-12-03 21:08:16","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/jamison-d-fargo\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"}],"sources":[{"ID":1316,"post_author":"0","post_date":"2018-12-03 15:58:16","post_date_gmt":"2018-12-03 14:58:16","post_content":"","post_title":"Journal of the Academy of Nutrition and Dietetics","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"journal-of-the-academy-of-nutrition-and-dietetics","to_ping":"","pinged":"","post_modified":"2018-12-03 15:58:16","post_modified_gmt":"2018-12-03 14:58:16","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/source\/journal-of-the-academy-of-nutrition-and-dietetics\/","menu_order":0,"post_type":"source","post_mime_type":"","comment_count":"0","filter":"raw"}]},"yoast_head":"\nA Randomized Controlled Trial of the Food Dudes Program: Tangible Rewards Are More Effective Than Social Rewards for Increasing Short- and Long-Term Fruit and Vegetable Consumption. -
