We studied the association between the local food environment and residents' report of recommended dietary intake.
Recommended intakes of foods and nutrients for 10 623 Atherosclerosis Risk in Communities participants were estimated from food frequency questionnaires. Supermarkets, grocery stores, and full-service and fast-food restaurants were geocoded to census tracts.
Black Americans' fruit and vegetable intake increased by 32% for each additional supermarket in the census tract (relative risk [RR] = 1.32; 95% confidence interval [CI] = 1.08, 1.60). White Americans' fruit and vegetable intake increased by 11% with the presence of 1 or more supermarket (RR = 1.11; 95% CI = 0.93, 1.32).
These findings suggest the local food environment is associated with residents' recommended diets.
我们研究了当地食物环境与居民报告的推荐膳食摄入量之间的关联。
通过食物频率问卷估计了社区动脉粥样硬化风险研究中10623名参与者的食物和营养素推荐摄入量。超市、杂货店、提供全方位服务的餐厅和快餐店被地理编码到普查区。
普查区每增加一家超市,非裔美国人的水果和蔬菜摄入量增加32%(相对风险[RR]=1.32;95%置信区间[CI]=1.08,1.60)。有1家或更多超市时,白人美国人的水果和蔬菜摄入量增加11%(RR=1.11;95%CI=0.93,1.32)。
这些发现表明当地食物环境与居民的推荐饮食有关。
