Food systems are the complex web of activities and interactions that include food production, transportation, processing, retailing, preparation, and finally disposal. While these food systems are generally thought of as largely agricultural or rural, Pothukuchi and Kaufman’s landmark paper in 1999 highlighted the importance of urban food systems in particular, and encouraged urban planners to incorporate food system considerations into municipal and regional plans. Areas of focus included: preserving agricultural land, preventing and processing food waste, environmental outcomes related to food production, processing, distribution, and storage, and ensuring adequate access to healthy food. This webinar will be an overview of food system planning interventions that have been implemented and evaluated since 1999, with a specific focus on outcomes related to environmental sustainability, economic development, availability of healthy food, individual food behaviours, and nutrition-…

Abstract

Almost two years since the start of the pandemic, significant psychosocial impacts are still observed in the Canadian population. The results of various surveys, as part of a study carried out by Université of Sherbrooke with the collaboration of international universities, have depicted the association between various risk/protective factors and mental health in times of pandemic. The most recent survey was conducted in October 2021 (in Canada, New Zealand and Switzerland) among a large and representative sample of adults. Special attention will be paid to the evolution in anxiety and depression and its associated risk/protective factors, as well as to a newly explored concept called “pandemic fatigue”. In addition to these results, some interesting comparisons between the attitudes, perceptions and responses towards the COVID-19 pandemic and climate change will be made. Lessons in disaster risk management learned over the past two years can indeed be utilized to…

The risk of contracting coronavirus varies among people and places, making some British Columbians more likely to be exposed to COVID-19 than others, due to socio-economic factors, occupational hazards, personal behaviours or other factors that are amplified in places characterised by increased risk of transmission. To better understand this, we developed a vulnerability model to identify differences in COVID-19 risks across neighbourhoods, visualized in a series of maps on a public-facing dashboard that indicate where to focus policy and public health efforts. In this presentation we discuss how we worked with patient partners and some of the actions that have been informed by our maps.

The population of adults aged 60-plus is growing rapidly around the world, expected to more than double to more than two billion by 2050, and the World Health Organization has declared 2020-2030 the “Decade of Healthy Ageing” in response to this demographic shift. Although much of the conversation around healthy aging has focused on individual risk factors and health behaviors, the built, natural, and social environments all play significant roles. This webinar will describe indicators of age-friendly environments at the community level, particularly in low- and middle-income countries and in rural settings, as well presenting findings from an indicator-development effort within the global Prospective Urban and Rural Epidemiology study (PURE). In light of the increased vulnerability to COVID-19 at this stage of life and the additional restrictions on social interactions that have resulted, we’ll also discuss what is known about roles for community design in reducing social…

There is no doubt that mental health challenges posed by disasters will increase due to climate, demographic and social changes. This presentation details findings from Canadian-led studies on the psychosocial impacts resulting from communities who experienced large-scale disasters in Canada. Such traumatic events include the COVID-19 pandemic, the 2019 Quebec spring floods, the 2016 Fort McMurray wildfires, and the 2013 Lac-Mégantic train derailment. There are links between observed psychosocial impacts and recovery during these recent disasters, with learnings that could be applied to the COVID-19 pandemic that could promote individual and community resilience following disasters. This session will be relevant to environmental and public health professionals in health prevention and health promotion roles. Presenter: Mélissa Généreux holds a doctorate in medicine, a master's degree in public health and a specialization in community medicine from the University of…

Fomite transmission is acknowledged as one of the potential transmission routes of SARS-CoV-2. Thus, appropriate cleaning and disinfection of surfaces is one of the non-pharmaceutical control measures recommended by public health. However, while adequate cleaning and disinfection may be important to sever this chain of transmission of COVID-19, excessive cleaning and disinfection has led to an increase in accidental exposure to harmful cleaning and disinfection by-products due to heightened concerns about SARS-CoV-2 persisting on food, food packaging, and environmental surfaces. Improving public health practitioners’ understanding of appropriate cleaning and disinfection practices and the risks of misuse and overuse of disinfectant products would help to guide public health recommendations in public and private settings.

Between June 20 and July 3, 2020 a COVID-19 outbreak associated with a personal service setting (PSS) was detected in the Kingston, Ontario and managed by the local public health unit (KFL&APH).

A mixed-methods analysis was conducted to review KFL&APH’s response to the outbreak. A social network analysis was conducted to determine the extent of the outbreak and route of acquisition of cases. Epidemic curves were created and analysed. Attack rates were calculated, and testing data and overall testing strategy were reviewed.

The outbreak consisted of 37 cases with 14 through direct PSS exposure. 23 cases were from subsequent generations, and a superspreading event led to 14 of those cases. The average age of cases was 38.6 years and 65% were female. One case required hospitalization. Over 10 000 tests were conducted using a multimodal approach, including fixed assessment centres, drive-through testing and targeted testing at outbreak sites. PCR lab results…

This presentation reviewed current understanding of the key risks associated with the performing arts sector, and the precautions for minimizing risks of COVID-19 transmission in various settings. It will be of interest to environmental and public health professionals developing guidance and recommendations for safe resumption of performing arts activities as well as those working in the sector.

The NCCEH Environmental Health Seminar Series provides an opportunity for learning and knowledge exchange on a variety of environmental health topics. See upcoming webinars.

This presentation synthesizes available evidence on environmental health risks associated with the physical environment in encampments, and best practices to prevent the transmission of SARS-CoV-2, to serve as guidance for environmental health practice as an integral part of a multi-sectoral approach to ensure people stay safe and healthy during their time in an encampment.
