BACKGROUND: <\/p>\n

Reducing fruit and vegetable (F&V) prices is a frequently considered policy to improve dietary habits in the context of health promotion. However, evidence on the effectiveness of this intervention is limited.<\/p>\n

OBJECTIVE: <\/p>\n

The objective was to examine the effects of a 50% price discount on F&Vs or nutrition education or a combination of both on supermarket purchases.<\/p>\n

DESIGN: <\/p>\n

A 6-mo randomized controlled trial within Dutch supermarkets was conducted. Regular supermarket shoppers were randomly assigned to 1 of 4 conditions: 50% price discounts on F&Vs, nutrition education, 50% price discounts plus nutrition education, or no intervention. A total of 199 participants provided baseline data; 151 (76%) were included in the final analysis. F&V purchases were measured by using supermarket register receipts at baseline, at 1 mo after the start of the intervention, at 3 mo, at 6 mo (end of the intervention period), and 3 mo after the intervention ended (9 mo).<\/p>\n

RESULTS: <\/p>\n

Adjusted multilevel models showed significantly higher F&V purchases (per household\/2 wk) as a result of the price discount (+3.9 kg; 95% CI: 1.5, 6.3 kg) and the discount plus education intervention (+5.6 kg; 95% CI: 3.2, 7.9 kg) at 6 mo compared with control. Moreover, the percentage of participants who consumed recommended amounts of F&Vs (≥400 g\/d) increased from 42.5% at baseline to 61.3% at 6 mo in both discount groups (P = 0.03). Education alone had no significant effect.<\/p>\n

CONCLUSIONS: <\/p>\n

Discounting F&Vs is a promising intervention strategy because it resulted in substantially higher F&V purchases, and no adverse effects were observed. Therefore, pricing strategies form an important focus for future interventions or policy. However, the long-term effects and the ultimate health outcomes require further investigation.<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-34870","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"Department of Health Sciences and the EMGO Institute for Health and Care Research, Faculty of Earth and Life Sciences, VU University Amsterdam, Amsterdam, Netherlands. w.waterlander@nihi.auckland.ac.nz\r\n","annee":"2013","mois":"4","numero":"97:4","page":"886-895","auteurs":[{"ID":34868,"post_author":"0","post_date":"2018-12-04 00:35:56","post_date_gmt":"2018-12-03 23:35:56","post_content":"","post_title":"Schuit","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"schuit","to_ping":"","pinged":"","post_modified":"2018-12-04 00:35:56","post_modified_gmt":"2018-12-03 23:35:56","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/schuit\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":27120,"post_author":"0","post_date":"2018-12-03 22:48:25","post_date_gmt":"2018-12-03 21:48:25","post_content":"","post_title":"Wilma Elzeline Waterlander","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"wilma-elzeline-waterlander","to_ping":"","pinged":"","post_modified":"2018-12-03 22:48:25","post_modified_gmt":"2018-12-03 21:48:25","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/wilma-elzeline-waterlander\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":34869,"post_author":"0","post_date":"2018-12-04 00:35:57","post_date_gmt":"2018-12-03 23:35:57","post_content":"","post_title":"De Boer","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"de-boer","to_ping":"","pinged":"","post_modified":"2018-12-04 00:35:57","post_modified_gmt":"2018-12-03 23:35:57","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/de-boer\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"}],"sources":[{"ID":1720,"post_author":"0","post_date":"2018-12-03 16:01:56","post_date_gmt":"2018-12-03 15:01:56","post_content":"","post_title":"Am J Clin Nutr.","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"am-j-clin-nutr","to_ping":"","pinged":"","post_modified":"2018-12-03 16:01:56","post_modified_gmt":"2018-12-03 15:01:56","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/source\/am-j-clin-nutr\/","menu_order":0,"post_type":"source","post_mime_type":"","comment_count":"0","filter":"raw"}]},"yoast_head":"\nPrice discounts significantly enhance fruit and vegetable purchases when combined with nutrition education: a randomized controlled supermarket trial. -
