    The intricate interplay between urban design, health, and equity has emerged as a critical focal point in pursuit of the United Nations Sustainable Development Goal 11, which seeks to make cities inclu¬sive, safe, resilient, and sustainable. It reflects an increasing aware¬ness of the social determinants of health – a term encapsulating the socioeconomic variables that shape an individual’s living and working conditions. In other words, a person’s-built environment (the human-made surroundings within which people live and work) can either support or detract from their health. This relationship is underscored by the impact of urban design on equity. With Canada now 80% urbanized, it is not surprising that cities and urban centers have emerged as a primary arena for addressing current health challenges and safeguarding the wellbeing of residents. Therefore, by recognizing the relationship between urban design and health provides an opportunity to address gaps that contribute to health inequities. However, not all municipal actors and urban design professionals readily acknowledge their pivotal role in improving population health. To understand how key municipal policy- and decision-makers view the relationship between health and urban design, our team used the City of Regina as a case study. We interviewed 30 municipal actors from various roles and educational backgrounds within Regina’s municipal government. These interviews were analyzed using qualitative research methods and the findings were used to inform this policy paper. We identified three key categories of barriers to integrating health and equity into urban design policies: constrained policy-making environment, societal and cultural factors, and competing interests of stakeholders.

    COVID-19 Vaccination and Public Health Countermeasures on Variants of Concern in Canada: Evidence From a Spatial Hierarchical Cluster Analysis
    (JMIR Publications Inc., 2022-05-31) Daniel A Adeyinka; Cory Neudorf; Cheryl A Camillo; Wendie N Marks; Nazeem Muhajarine
    Background There is mounting evidence that the third wave of COVID-19 incidence is declining, yet variants of concern (VOCs) continue to present public health challenges in Canada. The emergence of VOCs has sparked debate on how to effectively control their impacts on the Canadian population. Objective Provincial and territorial governments have implemented a wide range of policy measures to protect residents against community transmission of COVID-19, but research examining the specific impact of policy countermeasures on the VOCs in Canada is needed. Our study objective was to identify provinces with disproportionate prevalence of VOCs relative to COVID-19 mitigation efforts in provinces and territories in Canada. Methods We analyzed publicly available provincial- and territorial-level data on the prevalence of VOCs in relation to mitigating factors, summarized in 3 measures: (1) strength of public health countermeasures (stringency index), (2) the extent to which people moved about outside their homes (mobility index), and (3) the proportion of the provincial or territorial population that was fully vaccinated (vaccine uptake). Using spatial agglomerative hierarchical cluster analysis (unsupervised machine learning), provinces and territories were grouped into clusters by stringency index, mobility index, and full vaccine uptake. The Kruskal-Wallis test was used to compare the prevalence of VOCs (Alpha, or B.1.1.7; Beta, or B.1.351; Gamma, or P.1; and Delta, or B.1.617.2 variants) across the clusters. Results We identified 3 clusters of vaccine uptake and countermeasures. Cluster 1 consisted of the 3 Canadian territories and was characterized by a higher degree of vaccine deployment and fewer countermeasures. Cluster 2 (located in Central Canada and the Atlantic region) was typified by lower levels of vaccine deployment and moderate countermeasures. The third cluster, which consisted of provinces in the Pacific region, Central Canada, and the Prairies, exhibited moderate vaccine deployment but stronger countermeasures. The overall and variant-specific prevalences were significantly different across the clusters. Conclusions This “up to the point” analysis found that implementation of COVID-19 public health measures, including the mass vaccination of populations, is key to controlling VOC prevalence rates in Canada. As of June 15, 2021, the third wave of COVID-19 in Canada is declining, and those provinces and territories that had implemented more comprehensive public health measures showed lower VOC prevalence. Public health authorities and governments need to continue to communicate the importance of sociobehavioural preventive measures, even as populations in Canada continue to receive their primary and booster doses of vaccines.

    The Impact Of Provincial Proof- Of-Vaccination Policies On Age-Specific First-Dose Uptake Of COVID-19 Vaccines In Canada
    (Health Affairs (Project Hope), 2023-11-01) Tiffany Fitzpatrick; Cheryl A. Camillo; Shelby Hillis; Marin Habbick; Monika Roerig; Nazeem Muhajarine; Sara Allin
    Requirements of proof of COVID-19 vaccination were mandated for nonessential businesses and venues by Canada’s ten provinces throughout the fall of 2021. Leveraging variations in the timing of these measures across the provinces, we applied event study regression to estimate the impact the announcement of these measures had nationally on age-specific first-dose uptake in the subsequent seven-week period. Proof-of-vaccination mandate announcements were associated with a rapid, significant increase in first-dose uptake, particularly in people younger than age fifty. However, these behavioral changes were short- lived, with uptake returning to preannouncement levels—or lower—in all age groups within six weeks, despite mandates remaining in place for at least four months; this decline occurred earlier and was more apparent among adolescents ages 12–17. We estimated that nationally, 290,168 additional people received their first dose in the seven weeks after provinces announced proof-of-vaccination policies, for a 17.5 percent increase over the number of vaccinations estimated in the absence of these policies. This study provides novel age-specific evidence showing that proof-of-vaccination mandates led to an immediate, significant increase in national first-dose uptake and were particularly effective for increasing vaccination uptake in younger to middle-aged adults. Proof-of- vaccination mandates may be effective short-term policy measures for increasing population vaccination uptake, but their impact may differ across age groups.
