环境因素，如食物和餐具的颜色，已经被证明会影响成年人对食物和饮料的消费。这项概念验证研究调查了盘子颜色是否可以作为一种策略来减少学龄前儿童高能量密度（HED）零食的摄入，增加低能量密度（LED）零食的摄入。在受试者之间和受试者内部设计中，儿童被随机分配到对照组（没有颜色信息）或干预组（收到颜色信息：红色=停止，绿色=走），并在托儿所提供三种不同颜色的盘子（红色，绿色，白色），每种零食类型（HED， LED）。记录每个儿童的零食摄入量、颜色偏好、颜色联想和人体测量。结果显示，实验组（对照组与干预组）对HED （p = 0.540）和LED摄入量（p = 0.575）没有影响。盘子颜色对HED （p = 0.147）或LED零食摄入量（p = 0.505）没有明显影响。结合红绿两色板进行彩色与消色差的比较表明，彩色板对HED （p = 0.0503）和LED （p = 0.347）的进食量没有显著影响。尽管接受了短暂的学习干预，但在本研究中发现，使用盘子颜色是一种无效的策略，以控制学龄前儿童的零食摄入量。相反，我们认为幼儿的食物摄入量可能最好通过份量大小、能量密度和饮食行为特征来预测。
Environmental cues, such as the colour of food and dishware, have been shown to influence food and drink consumption in adult populations. This proof of concept study investigated whether plate colour could be utilised as a strategy to reduce intake of high energy density (HED) snacks and increase intake of low energy density (LED) snacks in pre-school children. In a between and within-subjects design, children were randomly assigned to either a control group (no colour message) or intervention group (received a colour message: red = stop, green = go) and were provided a snack at nursery on three occasions on differently coloured plates (red, green, white), for each snack type (HED, LED). Snack intake, colour preference, colour association, and anthropometrics were recorded for each child. The results showed that there was no effect of group (control vs intervention) on HED (p = 0.540) and LED intake (p = 0.575). No effect of plate colour on HED (p = 0.147) or LED snack intake (p = 0.505) was evident. Combining red and green plates for a chromatic versus achromatic comparison showed that there was no significant effect of chromatic plate on HED (p = 0.0503) and LED (p = 0.347) intakes. Despite receiving a brief learning intervention, the use of plate colour was found in the present study to be an ineffective strategy to control snack food intake in pre-school aged children. Rather, we suggest that food intake in young children may best be predicted by portion size, energy density and eating behaviour traits.
