简要总结

Regulated nutrition information is complex, using decimal places and percentages. Front of pack (FOP) labels provide simplified nutrition information on the front of packages. It has been suggested that the traditional approach to nutrition labeling is difficult for children to use; this is unfortunate as childhood is a critical time for developing long-lasting eating habits and children influence purchase decisions.

Materials and Methods Children aged 6-10 played a video game in which participants fed "Munchy Monster" the healthier of two cereal products presented on a computer screen. Across trials the FOP format varied in a 2 (color/no color) x 2 (facial emotion icon/no facial icon) factorial design. Within a trial both cereals presented the same FOP format, with one cereal healthier than the other.

Results Data suggest that color coding and/or facial icon significantly benefits selection accuracy and speed, particularly for the youngest children. Minimal training (awareness of the FOPs existence and that it might contain nutrition information) further improved accuracy and speed of responses.

Conclusions FOPs that leverage visual indicators assist even young children in assessing the nutritional value of a product.

详细描述

Background It has been estimated that only two percent of children eat a diet that is consistent with the Food Guide pyramid, consuming diets that are too high in fat, saturated fat and sodium, and too low in fiber. Furthering concerns associated with these statistics is the fact that childhood is a determinant phase in the establishment of eating habits, and that developing healthy eating practices as a child has long-term health benefits.

That said, children are an attractive segment for food marketers. Children are not only represent a primary market with growing access to discretionary income, children also have significant power to influence decisions and are a promising future market. As such, kids represent an attractive target for marketers, and research suggests vulnerability to the messages which target them.

It has been suggested that directing messages to children "increases children's preferences for the foods advertised and increases their requests to parents for those foods." Recognizing this, packaging plays an important role in the marketing mix. The US Federal Trade Commission (FTC) has estimated that 12% of all youth marketing expenditures are spent on packaging and in-store in store display materials. This is because of packaging's ability to influence purchase within retail spaces, at the point where purchasing decisions are made; something researchers have referred to as the "nag factor."

Clearly, the idea of presenting information directed at children using packaging for the purpose of motivating sales is utilized; however, the idea of presenting regulated information (e.g. nutritional information) in a format that might be readily understood by this vulnerable audience has not been widely explored. A major goal of nutritional labeling on food packages is to help consumers make appropriate choices. However, the current approach to nutritional labeling is targeted at adults, rather than children.

Although children as young as age four are capable of classifying familiar foods (e.g. ice cream vs. broccoli) as healthy or unhealthy, the investigators are the first to examine whether children can use visual cues from Front of Pack (FOP) labels to compare and evaluate food products from the same category (cereal). FOP labels appear on the front of packages and provide truncated information about nutrients that tend to be associated with disease (e.g. fats, trans fats, sugar and sodium).

盲法说明

Participants were handled differently in the methods. For the first block of participants, the FOP was not pointed out. For the second block, researchers merely pointed to the FOP and indicated that it might be helpful in decision making.

研究组 & 干预措施

Uninstructed Group

Other

For the first block of participants recruited (39, one of which withdrew from boredom), no overt reference was made regarding the FOP labels that were present on the images that participants viewed during the course of the video game. Participants comprising this block were referred to as "uninstructed."

干预措施: Four FOP label designs (Other)

Minimally trained

Other

Realizing that subjects might not use the FOP during decision making when not informed that it contained nutrition information, we conducted a second experiment (N= 41) which provided minimal information about the FOP. These subjects (the "minimally instructed" group) were provided with further instruction. At the beginning of the experiment, in addition to being shown the basic premise of the game and told that Munchy preferred to eat healthy options, the researcher pointed to one of the FOPs and told children "this information might be helpful when you decide what's healthy."
