目的：通过清楚地传达食品的健康，包装正面（FOP）标签有可能影响被认为适合消费的份量。本研究考察了每日摄入量指南（DIG）、多重交通信号灯（MTL）和健康星级评级（HSR） FOP标签与不存在FOP标签时对不健康食品适当份量的判断的影响。设计：受访者观看不健康的披萨、饼干、酸奶和玉米片的模拟包装，这些包装上有DIG、MU、HSR或没有FOP标签，并指出他们认为每种食物在单一场合应该吃的份量。设置：调查是在被调查者的个人电脑上完成的。受试者：共有1505名澳大利亚成年人在192个模拟包装中提供了4166个评级，这些包装涉及四种产品类别：披萨、酸奶、玉米片和饼干。结果：与没有FOP标签相比，HSR导致了比萨饼和玉米片选择适当份量的小但显著减少（P < 0-05）。与无FOP标签相比，MTL导致玉米片的选择量较小（P < 0-05）。结论：与没有FOP标签相比，当FOP标签上出现更多解释性格式（HSR， MU）时，受访者认为对一些（但不是全部）接受测试的食品来说，较小的份量是合适的。解释性较差的FOP标签（DIG）没有发现影响。解释性FOP标签可能会影响分量的判断，尽管影响程度不大。
Objective: By clearly conveying the healthiness of a food, front-of-pack (FOP) labels have the potential to influence the portion size considered appropriate for consumption. The present study examined the how the Daily Intake Guide (DIG), Multiple Traffic Lights (MTL) and Health Star Rating (HSR) FOP labels affect judgements of appropriate portion sizes of unhealthy foods compared with when no FOP label is present.Design: Respondents viewed mock packages of unhealthy variations of pizzas, cookies, yoghurts and cornflakes featuring the DIG, MU, HSR or no FOP label, and indicated the portion size they believed should be eaten of each food on a single occasion.Setting: The survey was completed on the respondent's personal computer.Subjects: A total of 1505 Australian adults provided 4166 ratings across 192 mock packages relating to four product categories: pizza, yoghurt, cornflakes and cookies.Results: Compared with no FOP label, the HSR resulted in a small but significant reduction in the portion size selected as appropriate for consumption of pizzas and cornflakes (P < 0-05). The MTL resulted in smaller portions of cornflakes being selected compared with no FOP label (P < 0-05).Conclusions: Respondents perceived smaller portion sizes as appropriate for some, but not all, of the foods tested when FOP labels with more interpretative formats (HSR, MU) appeared on-pack compared with no FOP label. No effect was found for the less interpretive FOP label (the DIG). Interpretive FOP labels may have the potential to influence portion size judgements, albeit at modest levels.
