The aim of this study is to evaluate the influence of meteorological factors on Ambrosia pollen concentrations and its impact on medical consultations for allergic rhinitis of residents from various socio-economic levels in Montréal (Québec, Canada) between 1994 and 2002. The study was conducted to recognize the sensitivity of pollen productivity to daily climate variability in order to estimate the consequences on human health vulnerability in the context of global climate change. Information related to medical consultations for allergic rhinitis due to pollen comes from the Quebec Health Insurance Board (Régie de l'assurance-maladie du Québec). Ambrosia pollen concentration was measured by the Aerobiology Research Laboratories (Nepean, Ontario). Daily temperature (maximum, minimum, and mean) and precipitation data were obtained from the Meteorological Service of Canada. Socio-economic data come from the 1996 and 2001 census data of Statistics Canada. Between 1994 and 2002, during the Ambrosia pollen season, 7667 consultations for allergic rhinitis due to pollen were recorded. We found a significant association between the number of medical consultations and pollen levels. Significant associations were detected for over-consultation the day of exposure, 1, 2, 3 and 5 days after exposure to high levels of pollen. The consultation rate is higher from low-income residents (3.10 consultations per 10,000 inhabitants) than for high-income (1.65 consultations per 10,000 inhabitants). Considering the demonstrated impact of pollen levels on health, it has become critical to ensure adequate monitoring of Ambrosia and its meteorological sensivity in the context of the anticipated climate change and its potential consequences on human health.
本研究的目的是评估气象因素对豚草花粉浓度的影响，以及其对1994年至2002年期间加拿大魁北克省蒙特利尔市不同社会经济水平居民过敏性鼻炎医疗咨询的影响。开展该研究是为了认识花粉产量对每日气候变化的敏感性，以便估计在全球气候变化背景下对人类健康脆弱性的影响。与花粉引起的过敏性鼻炎医疗咨询相关的信息来自魁北克医疗保险委员会。豚草花粉浓度由空气生物学研究实验室（安大略省内佩恩）测量。每日温度（最高、最低和平均）及降水数据来自加拿大气象服务局。社会经济数据来自加拿大统计局1996年和2001年的人口普查数据。在1994年至2002年豚草花粉季期间，记录到7667次因花粉导致的过敏性鼻炎医疗咨询。我们发现医疗咨询次数与花粉水平之间存在显著关联。在接触高水平花粉当天、接触后1天、2天、3天和5天出现过度咨询的情况中检测到显著关联。低收入居民的咨询率（每10000名居民3.10次咨询）高于高收入居民（每10000名居民1.65次咨询）。考虑到已证明的花粉水平对健康的影响，在预期的气候变化及其对人类健康的潜在后果背景下，确保对豚草及其气象敏感性进行充分监测已变得至关重要。
