Article Synopsis
  • The study explored whether introducing a 2/3 pint serving size of beer and cider could help reduce overall alcohol consumption in licensed premises in England.
  • Conducted across 22 locations, it used an ABA design to compare sales volumes during non-intervention and intervention periods, focusing on how the new serving size affected daily sales.
  • Results showed no significant change in the volume of beer and cider sold after adding the smaller serving size, highlighting the need for further research, particularly on the impact of removing larger serving sizes.

Background: Increasing the availability of non-alcoholic options is a promising population-level intervention to reduce alcohol consumption, currently unassessed in naturalistic settings. This study in an online retail context aimed to estimate the impact of increasing the proportion of non-alcoholic (relative to alcoholic) drinks, on selection and purchasing of alcohol.

Methods And Results: Adults (n = 737) residing in England and Wales who regularly purchased alcohol online were recruited between March and July 2021.

Does clear and transparent communication of risks, benefits, and uncertainties increase or undermine public trust in scientific information that people use to guide their decision-making? We examined the impact of reframing messages written in traditional persuasive style to align instead with recent "evidence communication" principles, aiming to inform decision-making: communicating a balance of risks and benefits, disclosing uncertainties and evidence quality, and prebunking misperceptions. In two pre-registered experiments, UK participants read either a persuasive message or a balanced and informative message adhering to evidence communication recommendations about COVID-19 vaccines (Study 1) or nuclear power plants (Study 2). We find that balanced messages are either perceived as trustworthy as persuasive messages (Study 1), or more so (Study 2).

Policies to reduce meat consumption are needed to help achieve climate change targets, and could also improve population health. Public acceptability can affect the likelihood of policy implementation. This study estimated the acceptability of policies to reduce red and processed meat consumption, and whether acceptability differed when policies were framed as benefitting health or the environment.

Article Synopsis
  • A recent study aimed to evaluate the impact of physical activity calorie equivalent (PACE) labels on the amount of calories purchased in worksite cafeterias, following a previous meta-analysis that suggested these labels might help people consume less.
  • The study was a randomized controlled trial conducted over 12 weeks across 10 cafeterias in England, involving around 19,000 workers and analyzing over 250,000 transactions.
  • Results showed no significant decrease in calories purchased, with minor changes in energy from intervention items and no notable effects on total energy purchased or revenue.

Article Synopsis
  • This study investigates whether reducing cigarette pack sizes from 25 to 20 can help smokers cut down on their daily intake.
  • Conducted as a randomized controlled trial in Canada, adult smokers participated in two 14-day periods where they smoked from both pack sizes.
  • Results showed that participants smoked an average of 1.3 fewer cigarettes per day from the 20-pack compared to the 25-pack, indicating that smaller pack sizes may encourage reduced smoking.

Background: Availability interventions have been hypothesised to make limited demands on conscious processes and, as a result, to be less likely to generate health inequalities than cognitively-oriented interventions. Here we synthesise existing evidence to examine whether the impact of altering the availability of healthier vs. less-healthy options differs by socioeconomic position.

Article Synopsis
  • The study aims to investigate whether using smaller bottles and glasses for wine at home can reduce overall alcohol consumption, potentially lowering the risk for various diseases.
  • Conducted as a randomized controlled trial in UK households, 260 households were analyzed based on the size of bottles (37.5 vs. 75 cl) and glasses (290 vs. 370 ml) used over two 14-day periods.
  • Results indicated a minor reduction in wine consumption when using smaller bottles, but a more significant decrease was observed with smaller glasses, where households consumed about 6.5% less wine.

Patients suffering from immune-mediated necrotizing myopathies (IMNM) harbor, the pathognomonic myositis-specific auto-antibodies anti-SRP54 or -HMGCR, while about one third of them do not. Activation of chaperone-assisted autophagy was described as being part of the molecular etiology of IMNM. Endoplasmic reticulum (ER)/sarcoplasmic reticulum (SR)-stress accompanied by activation of the unfolded protein response (UPR) often precedes activation of the protein clearance machinery and represents a cellular defense mechanism toward restoration of proteostasis.

Health warning labels (HWLs) show promise in reducing motivation towards energy-dense snack foods. Understanding the underlying mechanisms could optimise their effectiveness. In two experimental studies in general population samples (Study 1 n = 90; Study 2 n = 1382), we compared the effects of HWLs and irrelevant aversive labels (IALs) on implicit (approach) motivation towards unhealthy snacks, using an approach-avoidance task (Study 1), and a manikin task (Study 2).

Article Synopsis
  • Increased availability of lower-energy food options significantly influences individuals to choose healthier options as their top preference, as shown in two studies with UK adults.
  • When presented with predominantly lower-energy foods, participants were ten times more likely to select a lower-energy option compared to when higher-energy foods were emphasized.
  • About 90% of food choices reflected participants' highest-ranked options based on the available selections, highlighting the importance of preference in dietary choices influenced by availability.

Background: Effective interventions for reducing the consumption of products that harm population and planetary health often lack public support, impeding implementation. Communicating evidence of policies' effectiveness can increase public support but there is uncertainty about the most effective ways of communicating this evidence. Some policies have multiple benefits such as both improving health and the environment.

This article reviews the behavioural risks and possible mitigations for re-opening large venues for sports and music events when Covid-19 infection rates and hospitalizations begin to decline. We describe the key variables that we suggest will affect public behaviour relevant to the spread of the virus, drawing upon four sources: (1) relevant evidence and recommendations from the Scientific Pandemic Influenza Group on Behaviours produced for the Scientific Advisory Group for Emergencies (SAGE); (2) research evidence from non-pandemic conditions; (3) research on behaviour during the pandemic; and (4) relevant theory. We first outline some basic risks and a framework for understanding collective behaviour at live events.

Background: The physical properties of tableware could influence selection and consumption of food and alcohol. There is considerable uncertainty, however, around the potential effects of different sizes and shapes of tableware on how much food and alcohol people self-serve. These studies aimed to estimate the impact of: 1.
