The Synchronised Nutrition and Activity Program for Adults (SNAPA\u2122) was developed to address the need for accurate, reliable, feasible, inexpensive and low-burden methods for assessing specific dietary and physical activity behaviours in adults. Short-term test-retest reliability of SNAPA\u2122 was assessed in forty-four adults (age 41\u00b74 (sd 17\u00b73) years) who completed SNAPA\u2122 twice in 1 day. Concurrent validity against direct dietary observation and combined heart rate and accelerometry was assessed in seventy-seven adults (age 34\u00b74 (sd11\u00b71) years). Test-retest reliability revealed no substantial systematic shifts in mean values of the outcome variables: percentage of food energy from fat (% fat), number of portions of fruit and vegetables (FV) and minutes of moderate-to-vigorous physical activity (MVPA). For lunchtime dietary intake, the mean match rate between food items reported using SNAPA\u2122 and those observed was 81\u00b77 %, with a phantom rate of 5\u00b76 %. Pearson’s correlations between SNAPA\u2122 and the reference methods ranged from 0\u00b727 to 0\u00b756 for % fat, FV portions and minutes of MVPA. For % fat and FV intake, there was no fixed or proportional bias, and mean differences between the methods (SNAPA\u2122 – reference) were 5\u00b71 % and 0 portions, respectively. For minutes of MVPA, a fixed bias of – 28 min was revealed when compared with all minutes of MVPA measured by combined heart rate and accelerometry, whereas a proportional bias (slope 1\u00b747) was revealed when compared with minutes carried out in bouts ≥ 10 min. SNAPA\u2122 is a promising tool for measuring specific energy balance behaviours, though further work is required to improve accuracy for physical activity behaviours.<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-38593","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"Obesity Related Behaviours Research Group, Wolfson Research Institute, Durham University, Stockton-on-Tees TS17 6BH, UK.","annee":"2011","mois":"8","numero":"","page":"1-11","auteurs":[{"ID":38590,"post_author":"0","post_date":"2018-12-04 01:39:54","post_date_gmt":"2018-12-04 00:39:54","post_content":"","post_title":"Hillier","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"hillier","to_ping":"","pinged":"","post_modified":"2018-12-04 01:39:54","post_modified_gmt":"2018-12-04 00:39:54","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/hillier\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":38591,"post_author":"0","post_date":"2018-12-04 01:39:55","post_date_gmt":"2018-12-04 00:39:55","post_content":"","post_title":"Batterham","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"batterham","to_ping":"","pinged":"","post_modified":"2018-12-04 01:39:55","post_modified_gmt":"2018-12-04 00:39:55","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/batterham\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":38592,"post_author":"0","post_date":"2018-12-04 01:39:55","post_date_gmt":"2018-12-04 00:39:55","post_content":"","post_title":"Crooks","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"crooks","to_ping":"","pinged":"","post_modified":"2018-12-04 01:39:55","post_modified_gmt":"2018-12-04 00:39:55","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/crooks\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"}],"sources":[{"ID":1559,"post_author":"0","post_date":"2018-12-03 16:00:30","post_date_gmt":"2018-12-03 15:00:30","post_content":"","post_title":"Br J Nutr.","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"br-j-nutr","to_ping":"","pinged":"","post_modified":"2018-12-03 16:00:30","post_modified_gmt":"2018-12-03 15:00:30","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/source\/br-j-nutr\/","menu_order":0,"post_type":"source","post_mime_type":"","comment_count":"0","filter":"raw"}]},"yoast_head":"\nThe development and evaluation of a novel internet-based computer program to assess previous-day dietary and physical activity behaviours in adults: the synchronised nutrition and activity program for adults (snapa\u2122). -
