We also assessed whether this association depends on the geographic size of the food environment.<\/p>\n<p><strong>Methods<\/strong><\/p>\n<p>We analyzed data from the 2011 Los Angeles County Health Survey. We created buffers (from 0.25 to 3.0 miles in radius) centered in respondents&rsquo; residential addresses and counted the number of food outlets by type in each buffer. Dependent variables were weekly intake of fruits and vegetables, sugar-sweetened beverages, and fast food; BMI; and being overweight (BMI &ge;25.0 kg\/m<sup>2<\/sup>) or obese (BMI &ge;30.0 kg\/m<sup>2<\/sup>). Explanatory variables were the number of outlets classified as fast-food outlets, convenience stores, small food stores, grocery stores, and supermarkets. Regressions were estimated for all sets of explanatory variables and buffer size combinations (150 total effects).<\/p>\n<p><strong>Results<\/strong><\/p>\n<p>Only 2 of 150 effects were significant after being adjusted for multiple comparisons. The number of fast-food restaurants in nonwalkable areas (in a 3.0-mile radius) was positively associated with fast-food consumption, and the number of convenience stores in a walkable distance (in a 0.25-mile radius) was negatively associated with obesity.<\/p>\n<p><strong>Discussion<\/strong><\/p>\n<p>Little evidence was found for associations between proximity of respondents&rsquo; homes to food outlets and dietary intake or BMI among adults in Los Angeles County. A possible explanation for the null finding is that shopping patterns are weakly related to neighborhoods in Los Angeles County because of motorized transportation.<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-24689","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"Pardee RAND Graduate School, RAND Corporation, 1776 Main St, Santa Monica, CA 90407.
