The aim of this paper is to further develop an existing data model for mass-gathering health outcomes.

Mass-gathering events (MGEs) occur frequently throughout the world. Having an understanding of the complexities of MGEs is important to determine required health resources. Environmental, psychosocial, and biomedical domains may be a logical starting point to determine how data are being collected and reported in the literature; however, it may be that other factors influencing health resources are not identified within these domains.

Based on an exhaustive literature synthesis, this paper is the final paper in a series that explores the collection of variables that impact biomedical presentations associated with attendance/participation in MGEs.

The authors propose further evolution of the Arbon model to include the addition of several domains, including: event environment; command, control, and communication (C3); public health; health promotion; and legacy when reporting the health outcomes of an event.

Including a variety of domains that contribute to an MGE allows for formal evaluation of the event, which in turn informs future knowledge and skill development for both the event management group and the wider community.

To explore explicit beliefs about the controllability of obesity and the internalisation of negative weight-related stereotypes among public health trainees.

Cross-sectional online survey assessing explicit beliefs about the controllability of obesity using the Beliefs About Obese Persons Scale (BAOP) and internalisation of weight bias using the Modified Weight Bias Internalization Scale (WBIS-M). Bivariate associations between BAOP and WBIS-M scores and demographic characteristics were examined using t tests or ANOVA with post hoc Tukey’s tests.

School of Public Health at a large, Midwestern University.

Public health students (n 322).

Relative to students who identified as male, those who identified as female had a stronger belief that obesity is not within the control of the individual (P = 0·03), yet had more internalisation of weight bias (P < 0·01). Greater weight bias internalisation was also seen among students who perceived themselves to be of a higher weight status (P < 0·001) and those who were at risk for food insecurity (P < 0·01).

Public health trainees may be more attuned to the complexities of weight relative to trainees in other health-related fields, but are still susceptible to internalisation of negative weight-related stereotypes.

The information displayed on the packages of feeding bottles and teats commercialised in Montevideo (Uruguay) was analysed using content analysis with the goal of identifying key marketing practices that may discourage breast-feeding.

The study was conducted as part of the periodic assessment performed by the Uruguayan government to monitor the marketing of breast milk substitutes. All the feeding bottles and teats sold in forty-four retail outlets selling breast milk substitutes were purchased. The information available on the packages was analysed using content analysis and descriptive statistics.

Montevideo, Uruguay.

A total of 197 feeding bottles and 71 teats were found. The majority of the packages included information to enable caregivers to adequately use the products, including recommended age, instructions on how to use the products and instructions on the use of hygienic practices. However, the packages frequently included information that implied that bottle feeding was equivalent to breast-feeding, particularly from a physiological perspective, or that idealised product use. Idealisations included ability to reduce colic, improvements in the feeding experience and improvements in children’s health, well-being and development. Statements on the superiority of breast-feeding were infrequent.

The results from the present work showed the high prevalence of marketing practices on the packages of feeding bottles and teats that may discourage breast-feeding. Stricter and more detailed regulations seem necessary to enable caregivers to make informed feeding decisions for infants.

Much research effort is focused on developing an effective vaccine for combatting coronavirus disease 2019 (COVID-19). Vaccine development itself, however, will not be enough given that a sufficient amount of people will need to be vaccinated for widespread immunity. Vaccine hesitancy is on the rise, varies across countries, and is associated with conspiratorial worldview. Given the rise in COVID-19-related conspiracy theories, we aimed to examine the levels of COVID-19 vaccine hesitancy and its association with beliefs on the origin of the novel coronavirus in a cross-cultural study.

We conducted an online survey in the UK (N = 1088) and Turkey (N = 3936), and gathered information on participants' willingness to vaccinate for a potential COVID-19 vaccine, beliefs on the origin of the novel coronavirus, and several behavioural and demographic predictors (such as anxiety, risk perception, government satisfaction levels) that influence vaccination and origin beliefs.

In all, 31% of the participants in Turkey and 14% in the UK were unsure about getting themselves vaccinated for a COVID-19 vaccine. In both countries, 3% of the participants rejected to be vaccinated. Also, 54% of the participants in Turkey and 63% in the UK believed in the natural origin of the novel coronavirus. Believing in the natural origin significantly increased the odds of COVID-19 vaccine acceptance.

Our results point at a concerning level of COVID-19 vaccine hesitancy, especially in Turkey, and suggest that wider communication of the scientific consensus on the origin of the novel coronavirus with the public may help future campaigns targeting COVID-19 vaccine hesitancy.

To provide a micro-investigation into the long-term effects and process of implementation of a nudge intervention on food choice in sports canteens.

Multi-method case study.

Eight products were added to the range of foods and drinks in two football canteens in the Netherlands for 3 and 15 weeks, serving as a baseline period. In the intervention period, these products were promoted with the use of salience, scarcity, availability and default nudges, for 26 and 16 weeks, respectively. Aside from the collection of sales and revenue data, reach, acceptability, adherence and applicability were measured using observations, questionnaires and interviews.

Questionnaires were filled in by seventy and fifty-nine visitors of the canteens. Four interviews were held with board members and canteen personnel.

Mixed results were obtained regarding the suitability of nudges to be used to promote healthy eating in sports clubs. Sales and revenue data did show positive trends, the intervention was seen as acceptable by all stakeholders and the intervention had a large reach. However, adherence to the intervention in both canteens and the effects of the nudges on the total consumption pattern were low. Factors were identified that promoted or hindered the intervention at an individual, interventional and organisational level.

Nudges seem to be a valuable addition to other efforts to combat unhealthy eating. However, the extent of their impact as a single intervention tool is limited in the current food-abundant environment.
