Environmental determinants of infectious and chronic disease prevention behaviours: A systematic review and thematic synthesis of qualitative research.

Regulatory health policies facilitate desired health behaviours in communities, and among them, smoke-free policies and COVID-19 restrictions have been widely implemented. Qualitative research studies have explored how these measures and other environmental influences shape preventive behaviours. The objective of this systematic review was to synthesize previously published qualitative research, generate across-study themes, and propose recommendations for behaviour change interventions. We used a comprehensive search strategy, relevance screening and confirmation, data extraction, quality assessment, thematic synthesis, and quality-of-evidence assessment. In total, 87 relevant studies were identified. Findings were grouped under six overarching themes and mapped under three categories: (i) the political environment, (ii) the sociocultural environment, and (iii) the physical environment. These findings provide insights into the environmental influences of behaviour and indicate future interventions may be more effective by considering moral norms, community norms, policy support, and group identity.

Public Health Messaging to Address Indoor Tanning: A Scoping Review.

Indoor tanning (IT) is an avoidable skin cancer risk. Although numerous communication interventions have been assessed for IT deterrence, less attention has been paid to the persuasive messages within these interventions. This scoping review summarizes the current peer-reviewed literature on persuasive messages for IT. Overall, 20 articles (21 studies) were included. Most were experimental or quasi-experimental and conducted in the US. Participants were mostly young women who had tanned indoors before. Few studies evaluated persuasive theme; in those that did, health and appearance themes were effective. Narrative and statistical evidence formats were also effective. The included studies also supported normative messages, loss-framed messages, and images. Improved reporting on message design and evaluation would be beneficial for future evidence synthesis. Our understanding of persuasive messages for IT has expanded in recent years, but more research is needed to optimize them.

Explaining the food safety behaviours of food handlers using theories of behaviour change: a systematic review.

Theories of behaviour change can explain the factors affecting food handlers' use of food safety practices. A systematic review was conducted on this topic to identify which theories have been applied in this area and to determine which theories are the most consistent predictors of food handlers' behaviours. Standard systematic review procedures were followed: comprehensive search strategy; relevance screening of abstracts; article characterization; data extraction; risk-of-bias assessment; and descriptive analysis. Among 19 relevant studies, the most commonly investigated theories were the Theory of Planned Behaviour (n = 9 studies) and Health Belief Model (n = 5). All investigated theories were useful to explain food handlers' behavioural intentions and behaviours related to food safety across different settings, and could serve as useful frameworks for future research and practice. However, there was wide variability in the predictive ability of the theories and their specific constructs, indicating theories should be adapted to the local context of application.
