A conceptual model was proposed and tested in order to link attitudinal and awareness factors that might explain changes in food purchase behaviours and dietary patterns related to the Heart and Stroke Foundation of Canada's Health Check food information program.
Two hundred food shoppers completed a survey inquiring about demographics, diet-related health conditions, attitude toward healthy food purchases, use of food package information, and awareness, perceived value and reported use of the Health Check logo. Participants provided their receipt for groceries purchased and completed a dietary fat assessment. Path analysis was used to test the model.
Shoppers purchasing a Health Check product had lower fat intakes than shoppers who did not (30.4% vs. 33.9% calories from fat; p<0.05). There was strong association (beta=0.81; p<0.001) between logo awareness and use, and the meaning consumers attributed to the logo moderated this relationship (beta=0.53; p<0.01). Logo awareness was related to general use of food package information (beta=0.14; p<0.05) and attitude toward healthy food purchases (beta=0.15; p<0.05).
Persons successfully limiting their fat intake purchase Health Check products, suggesting the program has utility in this regard. Program promotional efforts should aim to increase understanding of the Health Check logo's meaning in helping to make healthier purchase decisions. Promotional efforts surrounding the introduction of new nutrition labels in Canada are also expected to have a positive effect on the program.
为了将可能解释与加拿大心脏与中风基金会健康检查食品信息项目相关的食品购买行为和饮食模式变化的态度及认知因素联系起来，提出并测试了一个概念模型。
200名食品购物者完成了一项调查，询问其人口统计学信息、与饮食相关的健康状况、对健康食品购买的态度、食品包装信息的使用情况，以及对健康检查标志的认知、感知价值和报告使用情况。参与者提供了购买食品杂货的收据，并完成了饮食脂肪评估。采用路径分析对模型进行测试。
购买健康检查产品的购物者的脂肪摄入量低于未购买者（来自脂肪的热量分别为30.4%和33.9%；p<0.05）。标志认知与使用之间存在强关联（β=0.81；p<0.001），消费者赋予标志的意义调节了这种关系（β=0.53；p<0.01）。标志认知与食品包装信息的一般使用情况（β=0.14；p<0.05）以及对健康食品购买的态度（β=0.15；p<0.05）相关。
成功限制脂肪摄入量的人会购买健康检查产品，这表明该项目在这方面具有实用性。项目推广工作应旨在提高对健康检查标志在帮助做出更健康购买决策方面意义的理解。加拿大新营养标签推出时的推广工作预计也会对该项目产生积极影响。
