title: [Effects of meteorological and environmental factors on subjective symptoms of allergic rhinitis in children].
abstract: OBJECTIVE
  To analyze the possible effects of meteorological and environmental factors on the subjective symptoms of allergic rhinitis (AR) in children.
  
  
  METHODS
  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.
  
  
  RESULTS
  The temperature and humidity had a negative correlation with symptoms score. Every 1 degrees C 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.
  
  
  CONCLUSIONS
  It suggested that higher temperature and higher humidity may induce lower sympotem while PM2. 5 and PM10 may induce higher sympotem in AR children.
