“…The role of airborne allergens on AR symptoms is well known, but the effect of pollens differs based on biogeographic conditions . Globally, due to the difference of geographic position and vegetation, the types and concentrations of airborne pollens will differ . Prior to this study (2014), pollen‐monitoring stations were established in the six study areas.…”

BackgroundThe aim of this study was to investigate the prevalence of epidemiologic and physician‐diagnosed pollen‐induced AR (PiAR) in the grasslands of northern China and to study the impact of the intensity and time of pollen exposure on PiAR prevalence.MethodsA multistage, clustered and proportionately stratified random sampling with a field interviewer‐administered survey study was performed together with skin prick tests (SPT) and measurements of the daily pollen count.ResultsA total of 6043 subjects completed the study, with a proportion of 32.4% epidemiologic AR and 18.5% PiAR. The prevalence was higher in males than females (19.6% vs 17.4%, P = .024), but no difference between the two major residential and ethnic groups (Han and Mongolian) was observed. Subjects from urban areas showed higher prevalence of PiAR than rural areas (23.1% vs 14.0%, P < .001). Most PiAR patients were sensitized to two or more pollens (79.4%) with artemisia, chenopodium, and humulus scandens being the most common pollen types, which were similarly found as the top three sensitizing pollen allergens by SPT. There were significant regional differences in the prevalence of epidemiologic AR (from 18.6% to 52.9%) and PiAR (from 10.5% to 31.4%) among the six areas investigated. PiAR symptoms were positively associated with pollen counts, temperature, and precipitation (P < .05), but negatively with wind speed and pressure P < .05).ConclusionPollen‐induced AR (PiAR) prevalence in the investigated region is extremely high due to high seasonal pollen exposure, which was influenced by local environmental and climate conditions.

“…Over recent decades, pollen seasons for some species have started earlier and lasted longer (Bielory, Lyons, and Goldberg 2012;Ziska et al 2011), while pollen concentrations have increased (Albertine et al 2014;Beggs 2004;D'Amato et al 2013). Longer pollen seasons and higher pollen concentrations are associated with increases in allergic rhinitis and asthma prevalence, causing increased emergency department visits and school days lost for children (Bielory, Lyons, and Goldberg 2012;Blando et al 2012).…”

Extreme weather and climate events affect human health by causing death, injury, and illness, as well as having large socioeconomic impacts. Climate change has caused changes in extreme event frequency, intensity, and geographic distribution, and will continue to be a driver for change in the future. Some of these events include heat waves, droughts, wildfires, flooding rains, coastal flooding, surges, and hurricanes. The pathways connecting extreme events to health outcomes and economic losses can be diverse and complex. The difficulty in predicting these relationships comes from the local societal and environmental factors that affect disease burden.

“…[9,10] Increased levels of pollutants such as carbon dioxide, ozone and nitrogen dioxide enhance the allergic response, [11] and pollutants may induce their own form of irritant rhinitis. Changes in vegetation biomes, as a result of climate change, are likely to cause changes in outdoor pollen and fungal allergens.…”
