There is much interest in the role of prices and financial incentives to encourage healthy diet, but no data from large population interventions.<\/p>\n<p><strong>PURPOSE<\/strong>:<br \/>\nThis study examines the effect of a price reduction for healthy food items on household grocery shopping behavior among members of South Africa&#039;s largest health plan.<\/p>\n<p><strong>METHODS<\/strong>:<br \/>\nThe HealthyFood program provides a cash-back rebate of up to 25% for healthy food purchases in over 400 designated supermarkets across all provinces in South Africa. Monthly household supermarket food purchase scanner data between 2009 and 2012 are linked to 170,000 households (60% eligible for the rebate) with Visa credit cards. Two approaches were used to control for selective participation using these panel data: a household fixed-effect model and a case-control differences-in-differences model.<\/p>\n<p><strong>RESULTS<\/strong>:<br \/>\nRebates of 10% and 25% for healthy foods are associated with an increase in the ratio of healthy to total food expenditure by 6.0% (95% CI=5.3, 6.8) and 9.3% (95% CI=8.5, 10.0); an increase in the ratio of fruit and vegetables to total food expenditure by 5.7% (95% CI=4.5, 6.9) and 8.5% (95% CI=7.3, 9.7); and a decrease in the ratio of less desirable to total food expenditure by 5.6% (95% CI=4.7, 6.5) and 7.2% (95% CI=6.3, 8.1).<\/p>\n<p><strong>CONCLUSIONS<\/strong>:<br \/>\nParticipation in a rebate program for healthy foods led to increases in purchases of healthy foods and to decreases in purchases of less-desirable foods, with magnitudes similar to estimates from U.S. time-series data.<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-34364","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"RAND Corporation, Santa Monica, California 90407-2138, USA. sturm@rand.org","annee":"2013","mois":"6","numero":"44:6","page":"567-572","auteurs":[{"ID":20234,"post_author":"0","post_date":"2018-12-03 20:33:18","post_date_gmt":"2018-12-03 19:33:18","post_content":"","post_title":"Roland Sturm","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"roland-sturm","to_ping":"","pinged":"","post_modified":"2018-12-03 20:33:18","post_modified_gmt":"2018-12-03 19:33:18","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/roland-sturm\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":34203,"post_author":"0","post_date":"2018-12-04 00:24:43","post_date_gmt":"2018-12-03 23:24:43","post_content":"","post_title":"Zhang","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"zhang","to_ping":"","pinged":"","post_modified":"2018-12-04 00:24:43","post_modified_gmt":"2018-12-03 23:24:43","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/zhang\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":29724,"post_author":"0","post_date":"2018-12-03 23:22:48","post_date_gmt":"2018-12-03 22:22:48","post_content":"","post_title":"Dinesh Kumar Patel","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"dinesh-kumar-patel","to_ping":"","pinged":"","post_modified":"2018-12-03 23:22:48","post_modified_gmt":"2018-12-03 22:22:48","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/dinesh-kumar-patel\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":34362,"post_author":"0","post_date":"2018-12-04 00:28:06","post_date_gmt":"2018-12-03 23:28:06","post_content":"","post_title":"Segal","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"segal","to_ping":"","pinged":"","post_modified":"2018-12-04 00:28:06","post_modified_gmt":"2018-12-03 23:28:06","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/segal\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"}],"sources":[{"ID":34363,"post_author":"0","post_date":"2018-12-04 00:28:07","post_date_gmt":"2018-12-03 23:28:07","post_content":"","post_title":"AM J PREV MED","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"am-j-prev-med-2","to_ping":"","pinged":"","post_modified":"2018-12-04 00:28:07","post_modified_gmt":"2018-12-03 23:28:07","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/source\/am-j-prev-med-2\/","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) -
