本文对80名哮喘儿童和50名喘支患儿进行了“模糊聚类”分析和多元分析等统计方法。结果显示,儿童哮喘有65%于3岁前起病,和喘支组相比,具有更高的阳性家族史、家族过敏史及本人过敏史;但在临床主要指标及体液、细胞免疫、白细胞计数、嗜酸性细胞计数等方面则无明显差別。两组样本经模糊聚类分析在λ=0.82高水平上完全聚为一类;而多元分析也表明支配两病的主要因素是发病年龄、发作频数、家族史、前驱症和婴幼儿期呼吸道疾病史。为此,作者认为,在排除其他喘息原因后,3岁以下不明原因的感染后反复喘息者当为婴幼儿哮喘。
In this paper, 80 asthma children and 50 children with asthma were subjected to “fuzzy clustering” analysis and multivariate statistical methods. The results showed that 65% of childhood asthma onset before the age of 3, and the asthma group had a higher positive family history, family history of allergy and my allergy history; but clinical indicators and body fluids, cellular immunity, white blood cells Count, eosinophil count and other aspects no significant difference. The two groups of samples were completely clustered by the fuzzy clustering analysis at a high level of λ = 0.82. Multivariate analysis also showed that the main factors that dominated the two diseases were age of onset, frequency of seizure, family history, prodromal disease and infantile respiratory disease history. To this end, the author believes that, after excluding the reasons for other wheezing, unexplained infections after 3 years of age, wheezing after repeated asthma as asthma in infants and young children.
