缺乏获得负担得起的健康食品被认为是不良饮食的一个促成因素。这项研究调查了地理和社会经济指数不同的地区的饮食与进入超市、交通、水果和蔬菜价格以及贫困之间的关系。对 1000 个地址进行的邮政调查（回复率为 42%）收集了有关家庭人口统计、超市和商店使用情况、汽车拥有量、流动性以及前一天水果和蔬菜摄入量的信息。邮政编码信息用于得出到最近超市的道路行驶距离和贫困指数。使用购物篮调查评估水果和蔬菜价格。广义线性回归模型用于确定水果和蔬菜摄入量的预测因子。男性杂货购物者吃的水果比女性杂货购物者少。随着年龄的增长，蔬菜的消费量略有增加。贫困、超市水果和蔬菜价格、到最近超市的距离以及杂货购物的潜在困难与水果或蔬菜消费没有显着相关。这些数据表明，食物荒漠的三个关键因素——水果和蔬菜价格、社会经济匮乏和当地超市的缺乏，并不是影响水果或蔬菜摄入量的因素。我们建议，旨在改善饮食的粮食政策应以改变对粮食的社会文化态度为导向。 (c) 2005 Elsevier Ltd. 保留所有权利。
Lack of access to affordable healthy foods has been suggested to be a contributory factor to poor diet. This study investigated associations between diet and access to supermarkets, transport, fruit and vegetable price and deprivation, in a region divergent in geography and socioeconomic indices. A postal survey of 1000 addresses (response rate 42%) gathered information on family demographics, supermarket and shop use, car ownership, mobility and previous day's fruit and vegetable intake. Postcode information was used to derive road travel distance to nearest supermarket and deprivation index. Fruit and vegetable prices were assessed Using a shopping basket survey. Generalised linear regression models were used to ascertain predictors of fruit and vegetable intake. Male grocery shoppers ate less fruit than female grocery shoppers. Consumption of vegetables increased slightly with age. Deprivation, supermarket fruit and vegetable price, distance to nearest supermarket and potential difficulties with grocery shopping were not significantly associated with either fruit or vegetable consumption. These data suggest that the three key elements of a food desert, fruit and vegetable price, socio-economic deprivation and a lack of locally available supermarkets, were not factors influencing fruit or vegetable intake. We suggest that food policies aimed at improving diet should be orientated towards changing socio-cultural attitudes towards food. (c) 2005 Elsevier Ltd. All rights reserved.
