英格兰于2022年在户外食品行业引入强制性卡路里标签，并提出了确保成本与份量相等的菜单定价策略（比例定价）作为减少肥胖的政策。基于食品配送应用程序的平台现在对饮食做出了重大贡献，有证据表明，那些处于社会经济劣势的人可能会在这些平台上更多地接触到不健康的选择。然而，改善从食品配送应用程序订购的食品营养质量的公共卫生政策受到了有限的审查。这项实验研究评估了卡路里标签和比例定价对项目和膳食大小选择的影响，订购的卡路里以及在虚拟交付应用程序上从三种类型的出口选择食物和饮料时花费的金钱。（N = 1126，49%女性），根据性别和教育水平进行分层，他们完成了一项在线研究，从三家品牌食品和饮料店订购物品参与者被呈现有与没有卡路里标签的食物和饮料选项，以及有价值的食物和饮料选项（较大的部分按比例便宜）与按比例定价。卡路里标签不影响任何商店的份量选择，但显著减少了从咖啡店（-18.95千卡，95%CI-33.07至-4.84）和快餐店（-54.19千卡，95%CI-86.04至-22.33）订购的卡路里。比例定价降低了从咖啡店选择较大饮料的可能性（OR = 0.58，95%CI 0.45至0.75），但与从快餐店订购的卡路里增加有关（51.25千卡，95%CI 19.59至82.90）。没有观察到与参与者特征一致的相互作用，这表明卡路里标签和定价对结果的影响在社会人口学群体中是相似的。食品配送平台上的卡路里标签可以有效地减少订购的卡路里。比例定价可能有助于促使消费者选择较小的份量，尽管在现实世界中的进一步研究现在将是有价值的。在线版本包含补充材料，可通过10.1186/s12966-023-01513-2获得。
Mandatory calorie labelling in the out-of-home food sector was introduced in England in 2022, and menu pricing strategies that ensure cost is equivalent to portion size (proportional pricing) have been proposed as a policy to reduce obesity. Food delivery app-based platforms now contribute significantly to diet, and evidence suggests that those at a socioeconomic disadvantage may have greater exposure to unhealthy options on these platforms. However, public health policies to improve nutritional quality of food ordered from food delivery apps has received limited examination. This experimental study assessed the impact of calorie labelling and proportional pricing on item and meal size selection, calories ordered, and money spent when selecting food and drinks from three outlet types on a virtual delivery app. UK adult participants (N = 1126, 49% female), stratified by gender and education level completed an online study where they ordered items from three branded food and beverage outlets (coffee shop, sandwich outlet, fast food outlet) using a virtual delivery app. Participants were presented food and beverage options with vs. without calorie labels and with value (larger portions are proportionally cheaper) vs. proportional pricing. Calorie labelling did not influence portion size selection for any outlets, but significantly reduced calories ordered from the coffee shop (-18.95kcals, 95% CI -33.07 to -4.84) and fast food outlet (-54.19kcals, 95% CI -86.04 to -22.33). Proportional pricing reduced the likelihood of choosing a larger beverage from the coffee shop (OR = 0.58, 95% CI 0.45 to 0.75), but was associated with increased calories ordered from the fast food outlet (51.25kcals, 95% CI 19.59 to 82.90). No consistent interactions were observed with participant characteristics, suggesting that effects of calorie labelling and pricing on outcomes were similar across sociodemographic groups. Calorie labelling on food delivery platforms may effectively reduce calories ordered. Proportional pricing may be useful in prompting consumers to select smaller portion sizes, although further research in real-world settings will now be valuable.
