Food environments play a key role in dietary behavior and vary due to different contexts, regulations, and policies.
This study aimed to characterize the perceived availability of healthy and unhealthy foods in 3 different settings in 5 countries.
We analyzed data from the 2018 International Food Policy Study, a cross-sectional survey of adults (18-100 y, n = 22,824) from Australia, Canada, Mexico, the United Kingdom (UK), and the USA. Perceived availability of unhealthy (junk food and sugary drinks) and healthy foods (fruit or vegetables, healthy snacks, and water) in the community, workplace, and university settings were measured (i.e. not available, available for purchase, or available for free). Differences in perceived availability across countries were tested using adjusted multinomial logistic regression models.
Across countries, unhealthy foods were perceived as highly available in all settings; in university and work settings unhealthy foods were perceived as more available than healthy foods. Australia and Canada had the highest perceived availability of unhealthy foods (range 87.5-90.6% between categories), and the UK had the highest perceived availability of fruits and vegetables for purchase (89.3%) in the community. In university and work settings, Mexico had the highest perceived availability for purchase of unhealthy foods (range 69.9-84.9%). The USA and the UK had the highest perceived availability of fruits and vegetables for purchase (65.3-66.3%) or for free (21.2-22.8%) in the university. In the workplace, the UK had high perceived availability of fruits and vegetables for purchase (40.2%) or for free (18.5%), and the USA had the highest perceived availability of junk food for free (17.3%).
Across countries, unhealthy foods were perceived as highly available in all settings. Variability between countries may reflect differences in policies and regulations. Results underscore the need for the continuation and improvement of policy efforts to generate healthier food environments.
食品环境在饮食行为中起着关键作用,并且由于不同的背景、法规和政策而有所不同。
本研究旨在描述五个国家三个不同环境中健康和不健康食品的可及性。
我们分析了 2018 年国际食品政策研究的数据,这是一项针对澳大利亚、加拿大、墨西哥、英国和美国 18-100 岁成年人(n=22824)的横断面调查。在社区、工作场所和大学环境中,分别测量了人们对不健康食品(垃圾食品和含糖饮料)和健康食品(水果或蔬菜、健康零食和水)的可及性(即不可获得、可购买或可免费获得)。使用调整后的多项逻辑回归模型检验了不同国家之间的感知可及性差异。
在所有环境中,各国都认为不健康食品高度可获得;在大学和工作场所,人们认为不健康食品比健康食品更易获得。澳大利亚和加拿大的人们认为最容易获得不健康食品(各分类之间的百分比在 87.5-90.6%之间),英国在社区中购买水果和蔬菜的比例最高(89.3%)。在大学和工作场所,墨西哥最容易购买到不健康食品(各分类之间的百分比在 69.9-84.9%之间)。美国和英国在大学中购买水果和蔬菜的比例最高(65.3-66.3%)或免费提供(21.2-22.8%)。在工作场所,英国购买水果和蔬菜的比例最高(40.2%)或免费提供(18.5%),而美国最容易获得免费的垃圾食品(17.3%)。
在所有环境中,不健康食品都被认为是高度可获得的。各国之间的差异可能反映了政策和法规的不同。这些结果强调了继续和改进政策努力以创造更健康的食品环境的必要性。
