Abstract

Objective: To assess associations between self-reported advertising exposure to foods high in fats, salt and sugar and household purchases of energy, nutrients and specific product categories.

Design: A cross-sectional design was used. Advertising exposure data were gathered using a questionnaire administered to the main shopper of each household, and purchase data from supermarkets and other stores for these households were accessed for a 4-week period during February 2019.

Setting: Households in London and the North of England.

Participants: Representative households (N 1289) from the Kantar Fast Moving Consumer Goods Panel. Main shoppers were predominantly female (71 %), with a mean age of 54 years (±13).

Results: Linear regression models identified that exposure to foods high in fats, salt and sugar advertising through traditional mediums (including broadcast and print), but not digital, transport, recreational or functional mediums, was associated with greater purchases of energy (9779 kcal; 95 % CI 3515, 16 043), protein (416 g; 95 % CI 161, 671), carbohydrate (1164 g; 95 % CI 368, 1886) and sugar (514 g; 95 % CI 187, 841). Generalised linear models showed that individuals who reported exposure to sugary drink advertising were more likely to purchase sugary drinks (1·16; 95 % CI 2·94, 4·99) but did not purchase more energy or nutrients from sugary drinks. There was no evidence of associations between exposure to advertising for sugary cereals or sweet snacks and purchases from these categories.

Conclusions: There was a strong influence of traditional advertising and sugar-sweetened beverage advertising on household food and drink purchases, thus supporting the need for advertising restrictions across traditional formats and for sugary drinks specifically.

接触高脂肪、高盐和高糖食品广告与购买能量和营养素之间的关系:一项横断面研究。
目的评估自我报告的高脂肪、高盐和高糖食品广告曝光量与家庭购买能量、营养素和特定产品类别之间的关联:设计:采用横断面设计。通过向每个家庭的主要购物者发放问卷收集广告曝光数据,并在2019年2月期间从超市和其他商店获取这些家庭为期4周的购买数据:伦敦和英格兰北部的家庭:来自 Kantar 快速消费品小组的代表性家庭(N 1289)。主要购物者以女性为主(71%),平均年龄为 54 岁(±13)岁:线性回归模型表明,通过传统媒体(包括广播和印刷媒体)而非数字、交通、娱乐或功能性媒体接触高脂肪、高盐和高糖食品广告,与购买更多能量(9779 千卡;95 % CI 3515,16 043)、蛋白质(416 克;95 % CI 161,671)、碳水化合物(1164 克;95 % CI 368,1886)和糖(514 克;95 % CI 187,841)有关。广义线性模型显示,报告接触过含糖饮料广告的人更有可能购买含糖饮料(1-16;95 % CI 2-94,4-99),但不会从含糖饮料中购买更多的能量或营养素。没有证据表明接触含糖谷物或甜味零食广告与购买这些类别的产品之间存在关联:传统广告和含糖饮料广告对家庭食品和饮料购买有很大影响,因此有必要对各种传统形式的广告和含糖饮料广告加以限制。
