| Research Abstract |
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.
