Abstract Wildfire smoke poses a serious and growing health threat to communities in the United States (US), Canada, beyond. Some populations—including children—are especially susceptible. Air Quality Indexes (AQIs) can inform parents about local air quality during events offer guidance on actions that protect children. In July–August 2023, from Oregon, Washington, California, British Columbia (BC) ( n = 2100) participated an online cross-sectional study. Binary ordinal logistic regression models were used examine geographic, demographic, psychosocial predictors of three dependent variables: knowledge where check AQI information, frequent checking information wildfire seasons, adherence messages around reducing/rescheduling outdoor physical activity. Smoke-exposure analysis indicated widespread potential exposures across all four jurisdictions. Nonetheless, BC, average, less likely report knowing checked frequently, adhere than US states. Adherence did not differ by jurisdiction presence other covariates, suggesting are equally follow when they know find it it. Other consistent variables included experience with prior smoke-related impacts, risk perceptions, use internet/mobile applications as sources information. These findings indicate increased promotion AQIs may benefit some regions wildfires. Future evaluations education initiatives could help agencies share effective practices jurisdictions target interventions increase adoption.

Wildfire activity is increasing around the world, concurrent with climate change, and mitigation strategies for protecting vulnerable populations are desperately needed. Because inhaled particles deleterious to respiratory health, particularly among older adults co-morbidities, we engaged maintenance personnel working in long term care facilities located Western US. Our objective was identify opportunities build resilience during wildfire smoke events. We implemented a virtual workshop that addressed health impacts as well assess maintain indoor air quality. A total of 24 attended 14 participated quantitative survey. Workshop attendees found value material there enthusiasm educational resources enhancing Four months later, four staff follow-up interview. qualitative assessment revealed following themes: awareness prioritization, application knowledge, barriers, resources. Access real-time actionable quality data consistent feature across these themes. Maintenance could play key role facility’s ability prepare respond events, this study highlights potential challenges involving them building strategies.

Abstract The threats to human health from wildfires and wildfire smoke (WFS) in the United States (US) are increasing due continued climate change. A growing body of literature has documented important adverse effects WFS exposure, but there is insufficient evidence regarding how risk related exposure varies across individual or community level characteristics. To address this gap, we utilized a large nationwide database healthcare utilization claims for emergency department (ED) visits California multiple seasons (May through November, 2012–2019) quantified impacts fine particulate matter <2.5 μ m (PM 2.5 ) air pollution attributable WFS, overall among subgroups population. We aggregated daily counts ED Zip Code Tabulation Area (ZCTA) used time-stratified case-crossover design distributed lag non-linear models estimate association between relative visits. further assessed with varied defined by age, race, social vulnerability, residential conditioning (AC) prevalence. Over 7 day period, PM was associated elevated all causes (1.04% (0.32%, 1.71%)), non-accidental (2.93% (2.16%, 3.70%)), respiratory disease (15.17% (12.86%, 17.52%)), not cardiovascular diseases (1.06% (−1.88%, 4.08%)). Analysis revealed potential differences susceptibility AC prevalence, ZCTA-level Social Vulnerability Index scores. These results suggest that higher rates cause, non-accidental, heterogeneity certain subgroups. Notably, lower availability risks activity.
