Study on the evaluation of risk factors for asthma-like symptom of three year old children

3岁儿童哮喘样症状危险因素评价研究。为探讨哮喘样症状发生的危险因素，对1993 ~ 1994年在东京市立公共卫生中心就诊的790名3岁儿童进行了过敏体质、婴儿营养、家庭吸烟、居住条件和取暖设备与哮喘样症状患病率的关系进行了分析。实验结果如下：1.实验结果表明：该研究确定男孩患病率为9.9%，女孩患病率为6.7%，总体平均患病率为8.3%，高于其他儿童研究。除支气管哮喘外，其他变应性疾病的医学记忆、过敏家族史和下支气管感染均对哮喘样症状的发生有影响。我们分析了尿潴留作为被动吸烟的生化指标。与吸烟者生活在一起的儿童尿失禁检出率（44.7%）高于未与吸烟者生活在一起的儿童（8.0%）。102个孩子被要求戴上一氧化氮暴露水平一些孩子记录了暴露水平。据认为，原因是由于冬季取暖设备的使用，孩子们在家里暴露在高一氧化氮环境中。不同类型暖气设备的使用与哮喘样症状的患病率无显著相关。

Study on the evaluation of risk factors for asthma-like symptom of three year old children.In order to study the risk factors for asthma-like symptom, the relationship was examined between allergic disposition, infantile nurtrition, smoking with family, dwelling condition and heating apparatus and the prevalence rate of asthma-like symptom in 790 three year old children who, for health chick up, visited the urban public health center located in Tokyo, in 1993-1994. The results were as follows ;1. The study established a prevalence rate of 9.9% in boys and 6.7% in girls with an overall average of 8.3%, which was higher than that of other stydies in children.2. Medical anamnesis of allergic disease except bronchial asthma, family history of allergy and infection of lower bronchus all were found influential to prevalence of asthma-like symptom.3. We analyzed urinary continine as a biochemical marker of passive smoking. The urinary continine detection rate (44.7%) of children who lived with smokers was higher than that (8.0%)of children who did not.4. One hundred and two children were requested to put on NO exposure levels were recorded by some children. It's thought the reason is the children were exposed to high NO at homes, due to the use of winter heating apparatus. But the use of various type heating apparatus was not related significantly to the prevalence rate of asthma-like symptom.
