The proximity of fast-food and convenience stores to schools may enhance access to unhealthy foods and have a negative impact on diet.<\/p>\n<p>PURPOSE: This study used spatial cluster analysis to determine whether food outlets are clustered around schools and evaluated the extent of food outlet clustering by school and school neighborhood sociodemographic characteristics.<\/p>\n<p>METHODS: The locations in 2008 of all schools, fast-food outlets, and convenience stores in five urban regions across New Zealand were geocoded. Using GIS analysis conducted in 2009, the number and proportion of outlets within 400-m and 800-m road distance around each school was calculated. The spatial clustering of food outlets within 1.5 km of schools was determined using a multi-type K-function. Food outlet type, school level, SES, the degree of population density, and commercial land use zoning around each school were compared.<\/p>\n<p>RESULTS: Primary\/intermediate schools had a total proportion of 19.3 outlets per 1000 students within 800 m compared to 6.6 for secondary schools. The most socially deprived quintile of schools had three times the number and proportion of food outlets compared to the least-deprived quintile. There was a high degree of clustering of food outlets around schools, with up to 5.5 times more outlets than might be expected. Outlets were most clustered up to 800 m from schools and around secondary schools, socially deprived schools, and schools in densely populated and commercially zoned areas.<\/p>\n<p>CONCLUSIONS: Food environments in New Zealand within walking proximity to schools are characterized by a high density of fast-food outlets and convenience stores, particularly in more-socially deprived settings. These obesogenic environments provide ready access to obesity-promoting foods that may have a negative impact on student diet and contribute to inequalities in health.<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-39412","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"Department of Geography, University of Canterbury, Christchurch, New Zealand. peter.day@canterbury.ac.nz\r\n","annee":"2011","mois":"2","numero":"40:2","page":"113-21","auteurs":[{"ID":1743,"post_author":"0","post_date":"2018-12-03 16:02:09","post_date_gmt":"2018-12-03 15:02:09","post_content":"","post_title":"Peter L Day","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"peter-l-day","to_ping":"","pinged":"","post_modified":"2018-12-03 16:02:09","post_modified_gmt":"2018-12-03 15:02:09","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/peter-l-day\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":1744,"post_author":"0","post_date":"2018-12-03 16:02:09","post_date_gmt":"2018-12-03 15:02:09","post_content":"","post_title":"Jamie R Pearce","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"jamie-r-pearce","to_ping":"","pinged":"","post_modified":"2018-12-03 16:02:09","post_modified_gmt":"2018-12-03 15:02:09","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/jamie-r-pearce\/","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) -
