How do different types of e-cigarette adverts affect perceptions of harm from tobacco smoking among children?

In two previous studies, we found that children exposed to e-cigarette adverts perceived occasional tobacco smoking as less harmful than children not exposed to such adverts. In this paper, we replicate and extend these findings using a larger sample, a stronger control condition and an updated meta-analysis.

This study adds to existing evidence that exposing children to adverts for e-cigarettes may reduce how harmful they perceive tobacco smoking to be. Further studies are warranted, using longitudinal and experimental designs, to assess a wider range of possible impacts of the marketing of e-cigarettes including attitudes towards the tobacco industry and tobacco control policies.

Winners and losers? The challenges of communicating policy options

To make policy decisions that align with our goals and values, we need to understand the expected outcomes of the different options. In this paper, we review existing communications of policy options, guidance for design, and evidence for effectiveness across a wide range of domains. Open-access.

What is the potential impact of calorie labelling in worksite cafeterias? A pilot study

Reducing excess consumption of food and drink is core to tackling the high prevalence of overweight and obesity in the UK and elsewhere. In this paper we provide the results of a pilot trial estimating the potential impact of calorie labelling on energy purchased across six worksite cafeterias. Post-intervention feedback amongst cafeteria patrons and worksite managers and caterers suggested high levels of acceptability. The predicted effect of labelling to reduce energy purchased was only evident at one out of six sites studied.

Taxing sweet snacks may bring even greater health benefits than taxing sugar-sweetened drinks

The UK Government levy on sugary drinks producers started in April 2018. This will potentially influence the cost of a large range of non-alcoholic beverages. Our new study (published 26th April 2018) looks at how increasing the price of snack foods might compare in impact. We found that a 10% increase in the price of sweet snacks could lead to a similar reduction in consumer demand as the same price increase for sugar-sweetened drinks. However, such a price increase is estimated to have knock-on effects that may further reduce purchases of sugar-sweetened drinks and other snacks. Furthermore, as sweet snacks provide twice as much sugar in the diet as sugar-sweetened drinks, the overall reduction on sugar intake could be even greater than that observed with price increases for sugar-sweetened drinks.

What is the impact of labelling wine and beer as lower in alcohol strength?

The aim of the present study was to assess the impact of lower strength alcohol labelling on consumption.

We found that the total amount of wine and beer consumed increased as the label on the drink denoted successively lower alcohol strength. Individual differences in drinking patterns and socio-demographic indicators did not affect these results.
