南京住宅采暖通风和空气感知对儿童感冒的影响

The Effects of Heating, Natural Ventilation and Air Perceptions in Residence on Children’s Common Cold in Nanjing

2010-2011年中国室内环境与儿童健康(CCHH)对南京主城11个区进行了儿童健康与室内环境相关性的横断面调查,共获得3820名3~7岁儿童有效问卷。本文主要利用卡方检验和逻辑回归主要分析了四季夜晚开窗通风、采暖方式和室内空气感知与儿童患感冒的差异和关联性。结果显示:春秋季夜晚经常开窗通风与儿童患感冒显著负相关,室内不新鲜气味、冬季室内感觉冷、父母感冒≥3次与儿童感冒显著正相关。使用电暖器是儿童感冒≥3次的危险因素,使用空气净化器是儿童感冒≥2周的危险因素,不同季节通风与空气感知对儿童感冒的影响具有"累积效应"。

In order to explore the association between indoor environment and child health, a cross-sectional survey was conducted by China, Children, Health, Home(CCHH) in 11 districts of Nanjing, China during 2010-2011. A total of3820 valid questionnaires on children aged 3-7 years old were collected and analyzed. A chi-square test and logistic regression methods were employed to analyze the differences and correlations between natural ventilation, heating,indoor air perceptions and children’s cold. The results showed that natural ventilation during spring and autumn nights were negatively associated with cold. The stuffy bad smell, the cold feeling in residence in winter and the parents had a cold ≥3 times in a year were positively associated with cold. Using electric heaters for heating was a risk factor for cold≥3 times in one year, and the use of air purifiers was a risk factor for a cold ≥2 weeks. A dose-response relationship between natural ventilation in different seasons, indoor air perceptions and children’s cold was found.
