PURPOSE: The aim was to assess nutrition; physical activity; and, secondarily, body weight in the tailored, social cognitive Guide to Health (GTH) Internet intervention delivered in churches. METHODS: Participants (N = 1,071; 33% male, 23% African American, 57% with body mass index &gt; or = 25, 60% sedentary, Mdn age = 53 years) within 14 Baptist or United Methodist churches were randomized to the GTH intervention only (GTH-Only; 5 churches), with church-based supports (GTH-Plus; 5 churches), or to a waitlist (control; 4 churches). Verified pedometer step counts, measured body weight, fat, fiber, and fruit and vegetable (F&amp;V) servings from food frequency and supermarket receipts were collected at pretest, posttest (7 months after pretest), and follow-up (16 months after pretest). RESULTS: Participants in GTH-Only increased F&amp;V at post (approximately 1.50 servings) compared to control (approximately 0.50 servings; p = .005) and at follow-up (approximately 1.20 vs. approximately 0.50 servings; p m = .038) and increased fiber at post (approximately 3.00 g) compared to control (approximately 1.5 g; p = .006) and follow-up (approximately 3.00 g vs. approximately 2.00 g; p = .040). GTH-Plus participants compared to control increased steps at post (approximately 1,500 steps\/day vs. approximately 400 steps\/day; p = .050) and follow-up (approximately 1,000 steps\/day vs. approximately &#8211; 50 steps\/day; p = .010), increased F&amp;V at post (approximately 1.5 servings; p = .007) and follow-up (approximately 1.3 servings; p = .014), increased fiber at post (approximately 3.00A g; p = .013), and follow-up (approximately 3.00; p = .050) and decreased weight at post (approximately &#8211; 0.30 kg vs. approximately + 0.60 kg; p = .030). CONCLUSIONS: Compared to control, both GTH treatments improved nutrition at posttest, but church supports improved physical activity and nutrition at posttest and follow-up, suggesting environmental supports may improve Internet-based interventions.<\/p>\n<p>PMID: 17600452 [PubMed &#8211; indexed for MEDLINE]\n","protected":false},"template":"","mots_cles":[],"class_list":["post-46958","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"Department of Psychology, Virginia Polytechnic Institute and State University, Blacksburg, VA 24061, USA. rswinett@vt.edu","annee":"2007","mois":"5","numero":"33:3","page":"251-61","auteurs":[{"ID":46953,"post_author":"0","post_date":"2018-12-04 04:09:39","post_date_gmt":"2018-12-04 03:09:39","post_content":"","post_title":"Winett","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"winett","to_ping":"","pinged":"","post_modified":"2018-12-04 04:09:39","post_modified_gmt":"2018-12-04 03:09:39","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/winett\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":46954,"post_author":"0","post_date":"2018-12-04 04:09:39","post_date_gmt":"2018-12-04 03:09:39","post_content":"","post_title":"Anderson","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"anderson-11","to_ping":"","pinged":"","post_modified":"2018-12-04 04:09:39","post_modified_gmt":"2018-12-04 03:09:39","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/anderson-11\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":46955,"post_author":"0","post_date":"2018-12-04 04:09:40","post_date_gmt":"2018-12-04 03:09:40","post_content":"","post_title":"Wojcik","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"wojcik","to_ping":"","pinged":"","post_modified":"2018-12-04 04:09:40","post_modified_gmt":"2018-12-04 03:09:40","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/wojcik\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":46956,"post_author":"0","post_date":"2018-12-04 04:09:41","post_date_gmt":"2018-12-04 03:09:41","post_content":"","post_title":"Winett","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"winett-2","to_ping":"","pinged":"","post_modified":"2018-12-04 04:09:41","post_modified_gmt":"2018-12-04 03:09:41","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/winett-2\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":46957,"post_author":"0","post_date":"2018-12-04 04:09:41","post_date_gmt":"2018-12-04 03:09:41","post_content":"","post_title":"Bowden","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"bowden","to_ping":"","pinged":"","post_modified":"2018-12-04 04:09:41","post_modified_gmt":"2018-12-04 03:09:41","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/bowden\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"}],"sources":[{"ID":1587,"post_author":"0","post_date":"2018-12-03 16:00:45","post_date_gmt":"2018-12-03 15:00:45","post_content":"","post_title":"Ann Behav Med.","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"ann-behav-med","to_ping":"","pinged":"","post_modified":"2018-12-03 16:00:45","post_modified_gmt":"2018-12-03 15:00:45","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/source\/ann-behav-med\/","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) -
