以前的研究检查宠物所有权作为呼吸系统疾病的风险因素，产生了不一致的结果。养宠物是否会改变空气污染物与儿童呼吸道症状和哮喘之间的关系，目前还知之甚少。为了评估宠物和空气污染对儿童呼吸健康的相互作用，我们招募了来自中国东北7个城市25个区的30，149名2-12岁儿童。孩子的父母完成了调查问卷，描述了孩子的呼吸道症状和疾病的历史以及相关的风险因素。通过25个研究区的监测站估计了空气动力学直径≤10 μm的颗粒物（PM10）、二氧化硫（SO2）、二氧化氮（NO2）和臭氧（O3）的平均环境年暴露量。结果表明，在家中没有宠物的儿童中，医生诊断的哮喘患者最近的哮喘恶化与呼吸道症状和所有检查的污染物之间存在统计学显着关联。对于PM10，比值比（OR）范围为1.12 [95%置信区间（CI），1.00-1.26]至1.41（95% CI，1.24-1.61）/31 μg m− 3，而在家中养宠物的儿童中，对哮喘或症状没有影响或影响很小。养狗与PM10、SO2、NO2和O3之间的相互作用具有统计学显著性，因此家中养狗的儿童当前哮喘和当前喘息的报告较低。总之，这项研究表明，养宠物减少了空气污染对中国儿童呼吸道症状和哮喘的影响。
Previous studies examining pet ownership as a risk factor for respiratory conditions have yielded inconsistent results. Little is known about whether or not pet ownership modifies the relationship between air pollutants and respiratory symptoms and asthma in children. In order to evaluate the interaction between pet and air pollution on respiratory health in children, we recruited 30,149 children, aged 2–12 years, from 25 districts of seven cities in northeast China. Parents of the children completed questionnaires that characterized the children's histories of respiratory symptoms and illnesses and associated risk factors. Average ambient annual exposures to particulate matter with an aerodynamic diameter ≤10 μm (PM10), sulfur dioxide (SO2), nitrogen dioxide (NO2), and ozone (O3) were estimated from monitoring stations in each of the 25 study districts. The results showed that among children without pets at home, there were statistically significant associations between both recent exacerbations of asthma among physician-diagnosed asthmatics and respiratory symptoms and all pollutants examined. Odds ratios (ORs) ranged from 1.12 [95% confidence interval (CI), 1.00–1.26] to 1.41 (95% CI, 1.24–1.61) per 31 μg m−3for PM10, whereas, among children with pets at home, there were no effects or small effects for either asthma or the symptoms. The interactions between dog ownership and PM10, SO2, NO2, and O3were statistically significant, such that children with a dog at home had lower reporting of both current asthma and current wheeze. In conclusion, this study suggests that pet ownership decreased the effects of air pollution on respiratory symptoms and asthma among Chinese children.
