The present study examined whether characteristics such as quality, selection and convenience are associated with dietary intake of fruits and vegetables independent of perceived costs in an inner-city, low-income population.
Secondary analysis of baseline data from a social marketing intervention designed to change household dietary practices among parents of 3- to 7-year-old children.
A community sample drawn from six low-income, primarily minority neighbourhoods in Chicago, IL, USA.
From the parent study, 526 respondents completed the baseline survey and were eligible for inclusion. Of this number, 495 provided complete data on sociodemographic characteristics, fruit and vegetable consumption, perceptions of the shopping environment, perceived costs of fruits and vegetables, and food shopping habits.
Logistic regression analysis showed that more positive perceptions of the food shopping environment were associated with greater consumption of fruits and vegetables. There was an increase of approximately twofold in the likelihood of consuming three or more fruits and vegetables daily per level of satisfaction ascribed to the shopping environment. This association was independent of perceived cost, store type and sociodemographic characteristics.
Our data show that among a generally minority and low-income population, quality, selection and convenience are important determinants of fruit and vegetable consumption. Nutrition promotion campaigns that aim to alter the built environment by increasing access to fruits and vegetables should recognize that simply increasing availability may not yield beneficial change when characteristics of the shopping context are ignored.
本研究旨在检验在一个城市中心、低收入人群中,质量、选择和便利性等特征是否与水果和蔬菜的摄入有关,而与感知成本无关。
这是一项针对旨在改变 3 至 7 岁儿童家长家庭饮食行为的社会营销干预措施的基线数据的二次分析。
从美国伊利诺伊州芝加哥的六个低收入、主要是少数族裔社区中抽取的社区样本。
从父母研究中,有 526 名受访者完成了基线调查,符合纳入标准。在这一数字中,有 495 人提供了关于社会人口特征、水果和蔬菜消费、对购物环境的看法、水果和蔬菜感知成本以及食品购物习惯的完整数据。
逻辑回归分析显示,对食品购物环境的看法越积极,水果和蔬菜的消费就越多。对购物环境的满意度每提高一个等级,每天食用三种或更多水果和蔬菜的可能性就会增加近两倍。这种关联独立于感知成本、商店类型和社会人口特征。
我们的数据表明,在一个普遍以少数族裔和低收入人群为主的群体中,质量、选择和便利性是水果和蔬菜消费的重要决定因素。旨在通过增加水果和蔬菜的可获得性来改变建筑环境的营养促进活动,应该认识到,当忽视购物环境的特征时,仅仅增加供应可能不会带来有益的变化。
