Health information on the dimensions of asthma and allergic conditions in Khuzestan Province, as a major industrial and polluted area in Iran as and the Middle East, is inadequate. This study was performed to measure the prevalence of asthma and other allergic conditions in adults in Khuzestan Province.
This population-based cross-sectional study was carried out in 17 villages and 27 cities of Khuzestan Province during the years 2017-2018 on 20 to 65 year old respondents. Two-stage cluster sampling was used. The ECRHS (European Community Respiratory Health Survey) questionnaire was completed for individuals with additional questions regarding other allergic conditions.
In the study, 5720 questionnaires were distributed of which 5708 were returned. The prevalence of current asthma was 8.5% and that of asthma-like symptoms was 19.0%. The most common symptoms of asthma were nocturnal cough (13.6%), chest tightness (12.3%) and wheezing (13.1%). The prevalence of allergic rhinitis (AR), eczema and airway hyperresponsiveness were 27.2, 10.7, and 38.7%, respectively. The prevalence of current asthma was strongly correlated with age, current location (city, village), and the smoking status of respondents (p < 0.05).
The prevalence of current asthma and asthma-like symptoms in Khuzestan Province is almost twice as high as in Iran. Given the high prevalence of symptoms of airway hyperresponsiveness in the entire province, it is necessary to take environmental measures to mitigate the emergence of new cases of asthma among the residents. In addition, surveillance studies are necessary to monitor the trends in the prevalence of asthma in this province.
作为伊朗和中东的主要工业和污染地区，有关胡齐斯坦省哮喘和过敏状况维度的健康信息不足。本研究旨在测量胡齐斯坦省成年人哮喘和其他过敏疾病的患病率。
这项基于人群的横断面研究于 2017 年至 2018 年在胡齐斯坦省的 17 个村庄和 27 个城市进行，调查对象为 20 至 65 岁的人群。采用两阶段聚类抽样。ECRHS（欧洲社区呼吸健康调查）问卷用于个体调查，如有其他过敏状况的问题，则会有附加问题。
研究共发放了 5720 份问卷，回收了 5708 份。目前哮喘的患病率为 8.5%，哮喘样症状的患病率为 19.0%。哮喘最常见的症状是夜间咳嗽（13.6%）、胸闷（12.3%）和喘息（13.1%）。过敏性鼻炎（AR）、湿疹和气道高反应性的患病率分别为 27.2%、10.7%和 38.7%。目前哮喘的患病率与年龄、当前所在地（城市、乡村）和受访者的吸烟状况密切相关（p<0.05）。
胡齐斯坦省目前哮喘和哮喘样症状的患病率几乎是伊朗的两倍。鉴于整个省份气道高反应性症状的高患病率，有必要采取环境措施来减轻居民中新发哮喘病例的出现。此外，还需要进行监测研究，以监测该省哮喘患病率的趋势。
