Many recreation and sports facilities have unhealthy food environments, however managers are reluctant to offer healthier foods because they perceive patrons will not purchase them. Preliminary evidence indicates that traffic light labeling (TLL) can increase purchase of healthy foods in away-from-home food retail settings. We examined the effectiveness of TLL of menus in promoting healthier food purchases by patrons of a recreation and sport facility concession, and among various sub-groups. TLL of all menu items was implemented for a 1-week period and sales were assessed for 1-week pre- and 1-week post-implementation of TLL (n = 2101 transactions). A subset of consumers completed a survey during the baseline (n = 322) and intervention (n = 313) periods. We assessed change in the proportion of patrons' purchases that were labeled with green, yellow and red lights from baseline to the TLL intervention, and association with demographic characteristics and other survey responses. Change in overall revenues was also assessed. There was an overall increase in sales of green (52.2% to 55.5%; p < 0.05) and a reduction in sales of red (30.4% to 27.2%; p < 0.05) light items from baseline to the TLL period. The effectiveness of TLL did not differ according to any of the demographic or other factors examined in the survey. Average daily revenues did not differ between the baseline and TLL periods. TLL of menus increased purchase of healthy, and reduced purchase of unhealthy foods in a publicly funded recreation and sport facility, with no loss of revenue. Policymakers should consider extending menu labeling laws to public buildings such as recreation and sports facilities to promote selection of healthier items.
许多娱乐和体育设施都存在不健康的食品环境，然而管理者不愿提供更健康的食品，因为他们认为顾客不会购买。初步证据表明，交通信号灯标签（TLL）可以增加在外出就餐零售场所对健康食品的购买。我们研究了菜单的交通信号灯标签在促进娱乐和体育设施小卖部顾客购买更健康食品方面的有效性，以及在不同亚组中的情况。所有菜单项的交通信号灯标签实施了1周，并在实施交通信号灯标签前1周和实施后1周评估销售额（n = 2101笔交易）。一部分消费者在基线期（n = 322）和干预期（n = 313）完成了一项调查。我们评估了从基线到交通信号灯标签干预期间，顾客购买的标有绿色、黄色和红色灯的商品比例的变化，以及与人口统计学特征和其他调查回复的关联。还评估了总收入的变化。从基线期到交通信号灯标签期，绿色灯商品的销售额总体增加（从52.2%增至55.5%；p < 0.05），红色灯商品的销售额减少（从30.4%降至27.2%；p < 0.05）。交通信号灯标签的有效性在调查中所考察的任何人口统计学或其他因素方面均无差异。基线期和交通信号灯标签期的日均收入没有差异。在一个公共资助的娱乐和体育设施中，菜单的交通信号灯标签增加了健康食品的购买，减少了不健康食品的购买，且没有收入损失。政策制定者应考虑将菜单标签法扩展到娱乐和体育设施等公共建筑，以促进更健康食品的选择。
