Effects of meteorological and environmental factors on subjective symptoms of allergic rhinitis in children
-
摘要: 目的:探讨变应性鼻炎(AR)患儿自觉症状与气象环境因素的相关性。方法:根据AR患儿自觉症状评分和上海市气象环境要素资料,应用线性混合效应模型进行统计分析,研究293例AR患儿自觉症状与同期气象环境要素的相关关系。结果:温湿度与AR患儿自觉症状评分呈负相关关系,平均温度每下降1℃,自觉症状评分升高0.04分(P<0.01),平均湿度每下降10%,自觉症状评分升高0.04分(P<0.05)。PM10和PM2.5与AR患儿自觉症状评分呈正相关关系,PM10和PM2.5每升高10 μg/m3,自觉症状评分分别升高0.02分(P=0.0246)和0.03分(P=0.0293)。结论:气象环境因素与儿童AR的自觉症状有较大的相关性,高温度和高湿度可能减轻AR患儿的自觉症状,而PM10和PM2.5浓度的增加可能加重AR患儿自觉症状。Abstract: Objective: To analyze the possible effects of meteorological and environmental factors on the subjective symptoms of allergic rhinitis (AR) in children.Method: According to the daily subjective symptom records in AR children, the relationship between the subjective symptoms of AR in children and the meteorological environmental factors was analyzed. Mixed model was used to analyze the data.Result: The temperature and humidity had a negative correlation with symptoms score. Every 1℃ of temperature decrease was linked to 0.04 points increase in subjective symptoms scores(P<0.01). Every 10% e in humidity decrease was linked to 0.04 points increase in subjective symptoms scores(P<0.05). There was positive relationship between PM2.5,PM10 and symptom scores. Every 10 μg/m3 increase of PM2.5 or PM10 was linked to 0.02 (P=0.0246) or 0.03 (P=0.0293) points increase in subjective symptoms scores, indicating that air pollution could aggravate the symptoms of children in AR.Conclusion: It suggested that higher temperature and higher humidity may induce lower sympotem while PM2.5 and PM10 may induce higher sympotem in AR children.
