Hospitals offer snacks for sale to patients, staff and visitors.
As food choice is heavily influenced by the options available, the present study (a) audited snack availability and purchase in NHS hospital sites across a large UK city; and (b) tested the potential effects of changes to this availability in an online choice experiment.
In Study 1 (audit), single-serve snacks (=376) available in 76 hospital food retail units were audited. Purchasing data were obtained from six food retail units over four weeks (27,989 sales). In Study 2 (online experiment), participants (=159) chose snacks from pictured ranges containing 25% (minority), 50% (equivalent) or 75% (majority) healthy options.
Available single-serve snacks varied markedly in calorie (18-641 kcals), fat (0-39 g), sugar (0.1-76 g) and salt (0-2.9 g). Only 30% of available snacks were healthy options and only 25% of the most commonly purchased snacks were healthy options. In Study 2, snack choice was significantly associated with the availability of healthy options in the choice array (X= 59.71, p<.01). More participants made healthy choices when product ranges contained 75% healthy options compared to 50% (p<.01) and 50% healthy options compared with 25% (p<.01).
Healthy snacks are readily available in NHS sites but there is a greater relative variety of unhealthy snack products. Many consumers continue to purchase unhealthy items. Further increasing the availability and variety of healthy options may support consumers to make healthier choices.
医院为患者、员工和访客提供销售的小吃。
由于食物选择受到可用选项的强烈影响,本研究(a)审查了英国一个大城市的 NHS 医院地点的小吃供应和购买情况;(b)在在线选择实验中测试了这种供应变化的潜在影响。
在研究 1(审核)中,审核了 76 个医院食品零售单位中提供的 376 种单份小吃。从六个食品零售单位在四周内获得购买数据(27989 笔销售)。在研究 2(在线实验)中,参与者(=159)从包含 25%(少数)、50%(同等)或 75%(多数)健康选择的图片范围内选择小吃。
可用的单份小吃在卡路里(18-641 卡路里)、脂肪(0-39 克)、糖(0.1-76 克)和盐(0-2.9 克)方面差异明显。只有 30%的可用小吃是健康选择,只有 25%的最常购买的小吃是健康选择。在研究 2 中,小吃选择与选择数组中健康选项的供应情况显著相关(X=59.71,p<.01)。当产品范围包含 75%的健康选择时,与 50%(p<.01)和 50%健康选择相比,参与者更倾向于选择健康的选择。
在 NHS 场所,健康小吃很容易获得,但不健康小吃产品的相对种类更多。许多消费者继续购买不健康的食品。进一步增加健康选择的供应和种类可能会支持消费者做出更健康的选择。
