Implementing physical activity calorie equivalent (PACE) food labelling: Views of a nationally representative sample of adults in the United Kingdom.

backgroundNutritional labels aim to support people to make informed healthy food choices, but many people do not understand the meaning of calories on food labels. Another approach is to provide calorie information with an interpretation of what the calorie content of food means for energy expenditure, known as physical activity calorie equivalent (PACE) labelling. PACE aims to illustrate how many minutes of physical activity are equivalent to the calories contained in food/drinks. This study investigated the views of the public about the possible implementation of PACE labelling.

methodsData was obtained from a nationally representative sample of adults in the United Kingdom and collected by UK Ipsos KnowledgePanel. Panellists are recruited via a random probability unclustered address-based sampling method. 4,000 panellists were randomly invited to participate and asked to compare their views about traffic light and PACE labelling preferences and behaviour parameters.

resultsData were analysed descriptively and using logistic and multinomial regression analyses. 2,668/4,000 (67%) of those invited participated. More participants preferred traffic light (43%vs33%) than PACE labelling, but more reported PACE was easier to understand (41%vs27%) and more likely to catch their attention (49%vs31%). More participants thought PACE was more likely to help them avoid high calorie food than traffic light labelling (44%vs28%). Physically active (3-4 or 5+ days/week) respondents were more likely to report PACE would catch their attention than traffic light labelling, compared with less active participants (weighted adjusted relative risk ratio = 1.42 (1.00-2.00) and 1.45 (1.03-2.05 respectively)). Perceived overweight was the most predictive factor (weighted adjusted OR = 2.24 (1.19 to 4.20)) in whether PACE was considered useful in helping people decide what to eat/buy.

conclusionThe public identified value to their health in labelling food with PACE information. PACE labelling may be a useful approach to complement current approaches to food labelling.
