<div><h3>Background</h3><div>The impact of past air quality improvements on health and equity at low pollution levels near the revised WHO air quality guidelines remains largely unknown. Less is known about the influence of simultaneous reductions in multiple major pollutants. Leveraging real-world improvements in air quality across Canada, we sought to directly evaluate their health benefits by quantifying the impact of a joint shift in three criteria pollutants on mortality in a national cohort.</div></div><div><h3>Methods</h3><div>In this population-based cohort study, we assembled a cohort of 2·7 million adults living in Canada in 2007 who were followed up through 2016. Annual mean concentrations of fine particulate matter (PM<sub>2·5</sub>), nitrogen dioxide (NO<sub>2</sub>), and ozone (O<sub>3</sub>) were assigned to participants’ residential locations. For each pollutant individually and combined, we conducted a causal analysis of the impact of the decadal shift in annual exposure from the pre-baseline level (2004–06) on the risk of non-accidental mortality using the parametric g-formula, a structural causal model. To check the robustness of our results, we conducted multiple sensitivity analyses, including exploring alternative exposure scenarios. We also evaluated differential benefits across regions and socio-demographic subgroups.</div></div><div><h3>Findings</h3><div>Between 2007 and 2016, annual mean exposures to PM<sub>2·5</sub> and NO<sub>2</sub> decreased (from 7·1 μg/m<sup>3</sup> [SD 2·3] to 5·5 μg/m<sup>3</sup> [1·9] for PM<sub>2·5</sub> and from 11·1 ppb [SD 6·6] to 8·0 ppb [4·9] for NO<sub>2</sub>), whereas O<sub>3</sub> declined initially and then rebounded (from 38·6 [SD 8·3] ppb to 36·0 [6·0] ppb and then 38·1 [5·4] ppb). Compared to pre-baseline (2004–06) levels, the joint change in the pollution exposures beginning in 2007 resulted in, per million population, 70 (95% CI 29–111) fewer deaths by 2009, 416 (283–549) fewer deaths by 2012, and 609 (276–941) fewer deaths by 2016, corresponding to a –0·7% change in mortality risk over the decade. Stratified analyses showed greater beneficial impacts in men, adults aged 50 years and older, low income-earners, and residents in regions undergoing substantial air quality improvements. Had all regions experienced pollution reductions similar to the most improved region, approximately three times as many deaths would have been averted (2191 fewer deaths per million). Conversely, if the observed air quality improvements had been delayed in all regions by 3 years, there would have been 429 more deaths per million by 2016.</div></div><div><h3>Interpretation</h3><div>In Canada, substantial health gains were associated with air quality improvements at levels near the revised WHO guidelines between 2007 and 2016, with notable heterogeneity observed across socio-demographic subgroups and regions.

Ambitious policies are urgently needed to protect human health from the impacts of climate change. Civil society, including researchers and advocates, can help advance such policies by communicating with policy makers. In this scoping review, we examined what is known about effectively communicating with policy makers to encourage them to act on public health, climate change, or their nexus. We analysed 139 studies published in the literature on health, climate, and their intersection that focused on strategies for communicating with policy makers. Among many other recommendations, the most frequently recommended communication strategies were to tailor messaging to target audiences; share accessible, concise, and timely evidence; and build coalitions and trusted relationships. The studies were largely about health communication to policy makers, were predominantly based in high-income countries, and most frequently used case studies, interviews, and surveys as methods. Further experimental research is needed to test the findings generated by non-experimental methods. Additionally, future research should seek to generate and test communication strategies in more low-income and middle-income countries. Based on this literature, we have produced a list of strategic questions that communicators might wish to consider as they prepare to communicate with policy makers.

Despite increasing emphasis being placed on the inclusion of upstream ecological and social perspectives for zoonotic disease control, few guidelines exist for practitioners and decision makers to work with communities in identifying suitable, locally relevant interventions and integrating these into public health action plans. With an interdisciplinary group of Kenyan stakeholders, we designed and tested a comprehensive framework for the co-design, evaluation, and prioritisation of beneficiary-oriented, ecologically and socially informed interventions for preventing and controlling outbreaks of wildlife-borne zoonoses. Our approach used four globally important wildlife-borne pathogens—Rift Valley fever virus, Congo–Crimean haemorrhagic fever virus, and the causative agents of anthrax and rabies—enabling stakeholders to develop a shared understanding of complex transmission pathways, identify a broad array of measures targeting ecological, biological, and social processes governing outbreaks of these pathogens, and explore trade-offs for specific interventions. The framework can be applied early in the decision-making process to encourage broader, cross-sectoral co-production of knowledge, ideas, and consensus on the control of complex zoonotic diseases.

Sand and dust storms increasingly threaten global environmental and public health. To date, 150 countries are directly affected, with more than 100 classified as non-dust source regions. With climate change, these storms are expected to become more frequent and severe. Despite international awareness and initiatives, such as those led by the UN, crucial knowledge gaps continue to hinder effective, evidence-based public responses to sand and dust storms. In this Viewpoint, we review existing gaps in health research and highlight four key research priorities: the comprehensive health effects of sand and dust storms, including short-term and long-term exposures, diseases, regions, and health outcomes; the key particle sizes and toxic components of particles during sand and dust storms; the design of multicentre studies accounting for region-specific exposure patterns; and research on health outcomes attributable to particulate matter mixtures dominated by windblown dust versus other sources. We urgently call for international, collaborative, and multidisciplinary health studies considering sand and dust storm exposure characteristics and for the adoption of scientifically robust epidemiological methods in these studies.
