PUBLIC HEALTH REVIEWS最新文献

Objectives: Complex systems thinking methods are increasingly called for and used as analytical lenses in public health research. The use of qualitative system mapping and in particular, causal loop diagrams (CLDs) is described as one promising method or tool. To our knowledge there are no published literature reviews that synthesize public health research regarding how CLDs are created and used. Methods: We conducted a scoping review to address this gap in the public health literature. Inclusion criteria included: 1) focused on public health research, 2) peer reviewed journal article, 3) described and/or created a CLD, and 4) published in English from January 2018 to March 2021. Twenty-three articles were selected from the search strategy. Results: CLDs were described as a new tool and were based upon primary and secondary data, researcher driven and group processes, and numerous data analysis methods and frameworks. Intended uses of CLDs ranged from illustrating complexity to informing policy and practice. Conclusion: From our learnings we propose nine recommendations for building knowledge and skill in creating and using CLDs for future public health research.

Objectives: The COVID-19 pandemic represents a major crisis for governments and populations. The public's risk perceptions, knowledge, and behaviors are key factors that play a vital role in the transmission of infectious diseases. Our scoping review aims to map the early evidence on risk perceptions, knowledge, and behaviors of general and high-risk adult populations towards COVID-19. Methods: A systematic scoping review was conducted of peer-reviewed articles in five databases on studies conducted during the early stages of COVID-19. Thirty-one studies meeting the inclusion criteria were appraised and analyzed. Results: The levels of risk perceptions, knowledge, and behaviors towards COVID-19 were moderate to high in both general and high-risk adult populations. Adults were knowledgeable about preventive behaviors. Our review identified hand-washing and avoiding crowded places as dominant preventive behaviors. Being a female, older, more educated, and living in urban areas was associated with better knowledge of COVID-19 and appropriate preventive behaviors. Conclusion: This review offers a first understanding of risk perceptions, knowledge and behaviors of adult populations during the early stages of the COVID-19 pandemic.

With COVAX touted as the only platform that is built on equity and fairness, there is growing discontent and concern that the platform is falling short of its goals as COVID ravages across multiple countries. There are two serious issues that we address here. Firstly, COVID distribution principles and mechanisms need to be rethought in terms of a shift from private to global interests with a focus on prioritizing deliveries. Secondly, with multiple vaccines present, it is vital that countries recognize all of them, once proven safe and effective, to prevent any form of vaccine apartheid and discrimination.

Background: When vaccines became first available during the Covid-19 pandemic, their demand significantly exceeded their supply. In consequence, the access to vaccines, initially, was distributed unequally. At the same time, governments started easing pandemic restrictions for vaccinated and recovered persons and restoring their freedoms since their risk of transmitting the virus is significantly reduced. Evidence: We show that restoring freedoms for vaccinated and recovered persons - while upholding restrictions for the rest of the population - is morally unfair during vaccine scarcity. Further, it may yield unintended side-effects, including perverse incentives, growing rifts in society, and the expansion of marginalization. Policy Options & Recommendations: We recommend accompanying easing for vaccinated and recovered individuals by mitigation measures for those who are neither vaccinated nor recovered. We propose, first, to temporarily lift the same restrictions for negative-tested individuals, as for vaccinated or recovered people. Second, the state must ensure broad and easy access to testing for everyone - free of charge. Conclusion: If done right, these mitigation measures create (at least temporarily) equal access to freedom for everybody - solving the moral problem of unfair access to freedoms and counteracting possible negative consequences.

Objectives: This research aimed to explore the health behaviours of health sciences students over time and across different settings. Methods: A health behaviour surveillance system has been implemented in Hamburg and Manchester among under- and postgraduate health sciences students. Trends among the Hamburg sample were described. In a cross-sectional assessment, health behaviours across both universities were examined using multivariate regression analysis. Results: Between 2014 and 2018, increasing trends in physical activity and cannabis and alcohol consumption were observed in Hamburg (n = 1,366). While fruit and vegetable intake was constantly low, tobacco smoking decreased. No clear trend was observed for stress perception. The comparison (n = 474) revealed that Manchester students had higher odds of smoking, excessive alcohol consumption, and fruit and vegetable consumption; and lower odds of being physically active, and consuming cannabis. No difference in stress perception was observed. Conclusions: Varying trends and potential areas of intervention were identified for health behaviours in Hamburg. The comparison with Manchester students revealed differences in behaviours, which could be further explored to help inform health promotion strategies in both settings.
