交通灯标签的食品，一个系统，结合了颜色编码的总脂肪，饱和脂肪，糖和盐的水平，在包装食品的前面，已被英国政府推荐，目前正在使用或正在逐步在许多英国制造商和零售商。本文介绍了一个试点随机对照试验的干预方案，旨在增加使用交通灯标签在现实生活中的食品购买决策。这项两组随机对照初步试验的目的是评估招募率、保留率和数据完成率，生成潜在效应量估计值，为主试验的样本量计算提供信息，并评估开展此类试验的可行性。参与者将通过电子邮件从英国连锁超市的忠诚卡数据库中招募。符合条件的参与者将超过18岁，经常购买即食餐或比萨饼的普通购物者。干预措施是通过审查以前的干预措施，鼓励使用营养标签和更广泛的行为改变文献。它的目的是影响机制，影响信念和行为意图的形成，以及那些与规划和目标设定和采用和维护的利益行为，即交通灯标签的使用在购买即食餐和比萨饼。数据将通过超市忠诚卡和基于网络的问卷调查使用电子销售数据收集，并将用于评估干预对购买的即食餐和比萨饼的营养状况以及与标签使用相关的行为机制的影响。数据收集将持续48周。将进行包括半结构化访谈和网络分析在内的过程评估，以评估全面试验的可行性。试点试验的设计考虑到了高效率的招募和数据收集。如果在主试验中证明干预可行，则可将其推广至更广泛的人群。ISRCTN：ISRCTN19316955
Traffic light labelling of foods—a system that incorporates a colour-coded assessment of the level of total fat, saturated fat, sugar and salt on the front of packaged foods—has been recommended by the UK Government and is currently in use or being phased in by many UK manufacturers and retailers. This paper describes a protocol for a pilot randomised controlled trial of an intervention designed to increase the use of traffic light labelling during real-life food purchase decisions. The objectives of this two-arm randomised controlled pilot trial are to assess recruitment, retention and data completion rates, to generate potential effect size estimates to inform sample size calculations for the main trial and to assess the feasibility of conducting such a trial. Participants will be recruited by email from a loyalty card database of a UK supermarket chain. Eligible participants will be over 18 and regular shoppers who frequently purchase ready meals or pizzas. The intervention is informed by a review of previous interventions encouraging the use of nutrition labelling and the broader behaviour change literature. It is designed to impact on mechanisms affecting belief and behavioural intention formation as well as those associated with planning and goal setting and the adoption and maintenance of the behaviour of interest, namely traffic light label use during purchases of ready meals and pizzas. Data will be collected using electronic sales data via supermarket loyalty cards and web-based questionnaires and will be used to estimate the effect of the intervention on the nutrition profile of purchased ready meals and pizzas and the behavioural mechanisms associated with label use. Data collection will take place over 48 weeks. A process evaluation including semi-structured interviews and web analytics will be conducted to assess feasibility of a full trial. The design of the pilot trial allows for efficient recruitment and data collection. The intervention could be generalised to a wider population if shown to be feasible in the main trial.
