To examine the effects of exposure to conflicting nutritional information (CNI) through different forms of media on nutrition-related confusion and backlash among consumers in the UK.
Cross-sectional survey administered via Qualtrics among 18-75-year-old participants in the UK. The sample was stratified by age and gender with quotas defined according to the 2011 UK census distribution.
Qualtrics' Online panel of respondents in the UK.
676 participants comprising nearly an equal number of females (n 341) and males (n 335) and a majority (58·6 %) from households whose income was <£30 000.
Our findings showed that nearly 40 % of respondents were exposed to some or a lot of CNI. We found that while exposure to CNI from TV and online news increased nutrition confusion, CNI from health professionals increased backlash. Exposure to CNI from social media and health websites was associated with reduced backlash. We also found that nutrition confusion and backlash were negatively associated with exercise behaviour and fruit and vegetable consumption, respectively.
Our study supports the theoretical pathways that explain the influence of CNI exposure on nutrition-related cognitive and behavioural outcomes. Additionally, different types of online information sources are associated with these outcomes to varying degrees. In the context of obesity and diabetes rates in the UK, our findings call for (a) further experimental research into the effects of CNI on consumers' diet-related cognitions and behaviours and (b) multi-stakeholder, interdisciplinary approaches to address this problem.
考察通过不同媒体形式接触冲突性营养信息（CNI）对英国消费者营养相关困惑和抵触情绪的影响。
在英国，通过 Qualtrics 对 18-75 岁的参与者进行横断面调查。该样本按年龄和性别分层，并根据 2011 年英国人口普查分布情况定义配额。
英国 Qualtrics 的在线受访者小组。
676 名参与者，其中女性（n=341）和男性（n=335）的数量几乎相等，且大多数（58.6%）来自收入<£30000 的家庭。
我们的研究结果表明，近 40%的受访者接触到一些或大量的 CNI。我们发现，虽然来自电视和在线新闻的 CNI 增加了营养困惑，但来自健康专业人士的 CNI 增加了抵触情绪。来自社交媒体和健康网站的 CNI 与减少抵触情绪有关。我们还发现，营养困惑和抵触情绪分别与锻炼行为和水果和蔬菜摄入呈负相关。
本研究支持解释 CNI 暴露对营养相关认知和行为结果影响的理论途径。此外，不同类型的在线信息来源在不同程度上与这些结果相关。在英国肥胖和糖尿病发病率的背景下，我们的研究结果呼吁（a）进一步开展关于 CNI 对消费者饮食相关认知和行为影响的实验研究，以及（b）采取多利益相关者、跨学科的方法来解决这一问题。
