This study examined objective distance to the nearest supermarket and participant-report of supermarket access in relation to fruit and vegetable intake. Street-network distance to the closest supermarket was calculated using GIS mapping. Perceived access was assessed by a survey question asking whether participants had a supermarket within walking distance of home. Cross-sectional survey data were collected from 828 low-income housing residents in three urban areas in greater-Boston. Generalized estimating equations were used to estimate the association between perceived and objective supermarket access and diet. Fruit and vegetable consumption was low (2.63 servings\/day). Results suggest that most low-income housing residents in greater-Boston do not live in &quot;food deserts,&quot; as the average distance to a supermarket was 0.76 km (range 0.13-1.22 km). Distance to a supermarket was not associated with fruit and vegetable intake (p = 0.22). Perceived supermarket access was strongly associated with increased fruit and vegetable intake (0.5 servings\/day) after controlling for socio-demographic covariates (p &lt; 0.0001). Patterns of mismatch between perceived and objective measures revealed that mismatch between the two measures were high (31.45%). Those who did not report a supermarket within walking distance from home despite the objective presence of a supermarket within 1 km consumed significantly fewer fruits and vegetables (0.56 servings\/day) than those with a supermarket who reported one, even after controlling for socio-demographic variables (p = 0.0008). Perceived measures of the food environment may be more strongly related to dietary behaviors than objective ones, and may incorporate components of food access not captured in objective measures.<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-36351","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"Harvard School of Public Health, 677 Huntingon Avenue, Boston, MA 02114, USA","annee":"2012","mois":"6","numero":"75:7","page":"1254-1262","auteurs":[{"ID":36350,"post_author":"0","post_date":"2018-12-04 00:58:36","post_date_gmt":"2018-12-03 23:58:36","post_content":"","post_title":"Subramanian","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"subramanian-2","to_ping":"","pinged":"","post_modified":"2018-12-04 00:58:36","post_modified_gmt":"2018-12-03 23:58:36","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/subramanian-2\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":20983,"post_author":"0","post_date":"2018-12-03 20:43:00","post_date_gmt":"2018-12-03 19:43:00","post_content":"","post_title":"Ichiro Kawachi","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"ichiro-kawachi","to_ping":"","pinged":"","post_modified":"2018-12-03 20:43:00","post_modified_gmt":"2018-12-03 19:43:00","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/ichiro-kawachi\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":24234,"post_author":"0","post_date":"2018-12-03 21:49:13","post_date_gmt":"2018-12-03 20:49:13","post_content":"","post_title":"Caitlin Eicher Caspi","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"caitlin-eicher-caspi","to_ping":"","pinged":"","post_modified":"2018-12-03 21:49:13","post_modified_gmt":"2018-12-03 20:49:13","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/caitlin-eicher-caspi\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"}],"sources":[{"ID":34890,"post_author":"0","post_date":"2018-12-04 00:36:12","post_date_gmt":"2018-12-03 23:36:12","post_content":"","post_title":"SOC SCI MED","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"soc-sci-med-2","to_ping":"","pinged":"","post_modified":"2018-12-04 00:36:12","post_modified_gmt":"2018-12-03 23:36:12","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/source\/soc-sci-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) -
