BackgroundThe COVID-19 pandemic has unprecedented consequences on population health, with governments worldwide issuing public health directives which have major impacts on normal living. In the absence of a vaccine, a key way to control the pandemic is through behavioural change: people adhering to transmission-reducing behaviours (TRBs), such as physical distancing, regular hand washing, and wearing face covering, especially when physical distancing is difficult. The application of behavioural science is central to understanding factors that influence adherence to TRBs. Non-adherence may be explained by theories of how people think about the illness (the common-sense model of self-regulation) and/or how they think about the TRBs (social cognition theory and protection motivation theory). In addition, outbreaks of infectious diseases and the measures employed to curb them are likely to have detrimental effects on people’s mental and general health. Therefore, in representative repeated surveys we will apply behavioural theories to model adherence to TRBs, explain variations in adherence, and the effects on mental and general health in the Scottish population from June to November 2020, following the initial outbreak of the COVID-19 pandemic.MethodsRepeated 20-minute structured telephone surveys will be conducted with nationally representative random samples of 500 adults from throughout Scotland. The first 6 weeks the survey will be conducted weekly, thereafter fortnightly, for a total of 14 waves (total n=7000). Ipsos MORI will recruit participants through random digit dialling. The core survey will measure adherence to TRBs, mental and general health, and explanatory variables from the theories. Further questions will be added, enabling more detailed measurement of constructs in the core survey, additional themes, and questions that align with the evolving pandemic. DiscussionThis study will provide insights into the link between (changes in) adherence to TRBs and explanatory factors, and their effects on mental and general health, including event-related changes (e.g., when government directives change). Governments and other decision-makers may use these findings to tailor public health promotion, target specific population groups, and develop behaviourally informed interventions over the duration of the COVID-19 pandemic (along with any subsequent equivalent events) to protect health and limit the spread of COVID-19.

Long Time

For a very long time in the COVID-19 crisis, behavioural change leading to physical distancing behaviour was the only tool at our disposal to mitigate virus spread. In this large-scale naturalistic experimental study we show how we can use behavioural science to find ways to promote the desired physical distancing behaviour. During seven days in a supermarket we implemented different behavioural interventions: (i) rewarding customers for keeping distance; (i) providing signage to guide customers; and (iii) altering shopping cart regulations. We asked customers to wear a tag that measured distances to other tags using ultra-wide band at 1Hz. In total N = 4,232 customers participated in the study. We compared the number of contacts (< 1.5 m, corresponding to Dutch regulations) between customers using state-of-the-art contact network analyses. We found that rewarding customers and providing signage increased physical distancing, whereas shopping cart regulations did not impact physical distancing. Rewarding customers moreover reduced the duration of remaining contacts between customers. These results demonstrate the feasibility to conduct large-scale behavioural experiments that can provide guidelines for policy. While the COVID-19 crisis unequivocally demonstrates the importance of behaviour and behavioural change, behaviour is integral to many crises, like the trading of mortgages in the financial crisis or the consuming of goods in the climate crisis. We argue that by acknowledging the role of behaviour in crises, and redefining this role in terms of the desired behaviour and necessary behavioural change, behavioural science can open up new solutions to crises and inform policy. We believe that we should start taking advantage of these opportunities.

Attitudes And Behavior

Abstract. The core aim of the present study is to compare the effects of a safety campaign and a behavior modification program on traffic safety. As is the case in community-based health promotion, the present study's approach of the attitude campaign was based on active participation of the group of recipients. One of the reasons why many attitude campaigns conducted previously have failed may be that they have been society-based public health programs. Both the interventions were carried out simultaneously among students aged 18-19 years in two Norwegian high schools (n = 342). At the first high school the intervention was behavior modification, at the second school a community-based attitude campaign was carried out. Baseline and posttest data on attitudes toward traffic safety and self-reported risk behavior were collected. The results showed that there was a significant total effect of the interventions although the effect depended on the type of intervention. There were significant differences in attitude and behavior only in the sample where the attitude campaign was carried out and no significant changes were found in the group of recipients of behavior modification.

The Relationship

Background: The relationship between oral health and general health is gaining interest in geriatric research; however, a lack of studies dealing with this issue from a general perspective makes it somewhat inaccessible to non-clinical public health professionals. Purpose: The purpose of this review is to describe the relationship between oral health and general health of the elderly on the basis of literature review, and to give non-clinical medical professionals and public health professionals an overview of this discipline. Methods: This study was based on an in-depth review of the literature pertaining to the relationship between oral health and general health among the older people. The tools commonly used to evaluate dental health and the academic researches of male elderly people were also reviewed. And future research directions were summarized. Results: Dental caries, periodontal disease, edentulism, and xerostomia are common oral diseases among the older people. Dental caries and periodontal diseases are the leading causes of missing teeth and edentulism. Xerostomia, similar to dry mouth, is another common oral health disease in the older people. No clear correlation exists between the subjective feeling of dryness and an objective decrease of saliva. Rather, both conditions can be explained by changes in saliva. The General Oral Health Assessment Index (GOHAI) and the Oral Health Impact Proﬁle (OHIP) are the main assessment tools used to examine oral health and quality of life in the older people. The GOHAI tends to be more sensitive to objective values pertaining to oral function. In addition, oral health studies in male elderly people are population-based cohort or cross-sectional studies, involving masticatory function, oral prevention, frailty problems, cardiovascular disease risk, and cognitive status. Conclusion: It is possible to reduce the incidence of certain oral diseases, even among individuals who take oral health care seriously. Oral health care should be based on the viewpoint of comprehensive treatment, including adequate nutrition, good life and psychology, and correct oral health care methods. In the future, researchers could combine the results of meta-analysis with the clinical experience of doctors to provide a more in-depth and broader discussion on oral health research topics concerning the older people.

Abstract Background Despite scientific evidence that climate change has profound and far reaching implications for public health, translating this knowledge in a manner that supports citizen engagement, applied decision-making, and behavioural change can be challenging. This is especially true for complex vector-borne zoonotic diseases such as Lyme disease, a tick-borne disease which is increasing in range and impact across Canada and internationally in large part due to climate change. This exploratory research aims to better understand public risk perceptions of climate change and Lyme disease in order to increase engagement and motivate behavioural change. Methods A focus group study involving 61 participants was conducted in three communities in the Canadian Prairie province of Manitoba in 2019. Focus groups were segmented by urban, rural, and urban-rural geographies, and between participants with high and low levels of self-reported concern regarding climate change. Results Findings indicate a broad range of knowledge and risk perceptions on both climate change and Lyme disease, which seem to reflect the controversy and complexity of both issues in the larger public discourse. Participants in high climate concern groups were found to have greater climate change knowledge, higher perception of risk, and less skepticism than those in low concern groups. Participants outside of the urban centre were found to have more familiarity with ticks, Lyme disease, and preventative behaviours, identifying differential sources of resilience and vulnerability. Risk perceptions of climate change and Lyme disease were found to vary independently rather than correlate, meaning that high climate change risk perception did not necessarily indicate high Lyme disease risk perception and vice versa. Conclusions This research contributes to the growing literature framing climate change as a public health issue, and suggests that in certain cases climate and health messages might be framed in a way that strategically decouples the issue when addressing climate skeptical audiences. A model showing the potential relationship between Lyme disease and climate change perceptions is proposed, and implications for engagement on climate change health impacts are discussed.

This project investigated how alternative non-stigmatising public health messages influence people’s health behaviours and well-being, relative to traditional stigmatising weight-loss messages. We conducted three experimental studies (total N = 1281) that compared traditional weight-loss messages to weight-neutral messages (Study 1), weight-inclusive messages (Study 2) and size acceptance messages (Study 3). Results revealed that public health messages have differential effects on health behaviours and well-being, depending on the audience’s BMI or perceived weight. However, campaigns that challenge weight stigma and promote body positivity have positive effects on some psychological indicators of health and well-being for people of all body sizes.

Background: Effective interventions and commercial programmes for weight loss (WL) are widely available, but most people regain weight. Few effective WL maintenance (WLM) solutions exist. The most promising evidence-based behaviour change techniques for WLM are self-monitoring, goal setting, action planning and control, building self-efficacy, and techniques that promote autonomous motivation (e.g., provide choice). Stress management and emotion regulation techniques show potential for prevention of relapse and weight regain. Digital technologies (including networked-wireless tracking technologies, online tools and smartphone apps, multimedia resources, and internet-based support) offer attractive tools for teaching and supporting long-term behaviour change techniques. However, many digital offerings for weight management tend not to include evidence-based content and the evidence base is still limited. The Project: First, the project examined why, when, and how many European citizens make WL and WLM attempts and how successful they are. Second, the project employed the most up-to-date behavioural science research to develop a digital toolkit for WLM based on 2 key conditions, i.e., self-management (self-regulation and motivation) of behaviour and self-management of emotional responses for WLM. Then, the NoHoW trial tested the efficacy of this digital toolkit in adults who achieved clinically significant (≥5%) WL in the previous 12 months (initial BMI ≥25). The primary outcome was change in weight (kg) at 12 months from baseline. Secondary outcomes included biological, psychological, and behavioural moderators and mediators of long-term energy balance (EB) behaviours, and user experience, acceptability, and cost-effectiveness. Impact: The project will directly feed results from studies on European consumer behaviour, design and evaluation of digital toolkits self-management of EB behaviours into development of new products and services for WLM and digital health. The project has developed a framework and digital architecture for interventions in the context of EB tracking and will generate results that will help inform the next generation of personalised interventions for effective self-management of weight and health.

Abstract Background Whole genome sequencing of cultured pathogens is the state of the art public health response for the bioinformatic source tracking of illness outbreaks. Quasimetagenomics can substantially reduce the amount of culturing needed before a high quality genome can be recovered. Highly accurate short read data is analyzed for single nucleotide polymorphisms and multi-locus sequence types to differentiate strains but cannot span many genomic repeats, resulting in highly fragmented assemblies. Long reads can span repeats, resulting in much more contiguous assemblies, but have lower accuracy than short reads. Results We evaluated the accuracy of Listeria monocytogenes assemblies from enrichments (quasimetagenomes) of naturally-contaminated ice cream using long read (Oxford Nanopore) and short read (Illumina) sequencing data. Accuracy of ten assembly approaches, over a range of sequencing depths, was evaluated by comparing sequence similarity of genes in assemblies to a complete reference genome. Long read assemblies reconstructed a circularized genome as well as a 71 kbp plasmid after 24 h of enrichment; however, high error rates prevented high fidelity gene assembly, even at 150X depth of coverage. Short read assemblies accurately reconstructed the core genes after 28 h of enrichment but produced highly fragmented genomes. Hybrid approaches demonstrated promising results but had biases based upon the initial assembly strategy. Short read assemblies scaffolded with long reads accurately assembled the core genes after just 24 h of enrichment, but were highly fragmented. Long read assemblies polished with short reads reconstructed a circularized genome and plasmid and assembled all the genes after 24 h enrichment but with less fidelity for the core genes than the short read assemblies. Conclusion The integration of long and short read sequencing of quasimetagenomes expedited the reconstruction of a high quality pathogen genome compared to either platform alone. A new and more complete level of information about genome structure, gene order and mobile elements can be added to the public health response by incorporating long read analyses with the standard short read WGS outbreak response.
