Model building for environmental risk analysis and data collection

1。我在Asakura Shoten出版的一本医学书籍中撰写了一章，题为“测量误差的评估”，其中包括从该研究中获得的部分结果。开发并上传了多变量测量误差模型的Fortran程序。针对饮食习惯和遗传因素开发了触摸屏问卷调查系统，通过触摸显示面板自动将答案积累到Access文件中。问题涉及(A)特应性皮炎诊断，(B)食用肉类、小鱼、大鱼和鸡蛋的频率，(C)在寿司中经常吃鱼，(D)3。在长崎市公共保健中心接受健康评估服务的人中，约有80%的人自愿在该系统上回答了问题。然而，由于需要大约十分钟的时间来完成，有些人无法回答。最后得出的结论是，问题卷适合同时处理许多人的问题。600名儿童中约有7%患有皮炎或相似症。多因素logistic回归模型显示：(1)当亲属有特应性、哮喘或过敏体质时，特应性的风险高。(2)女性发生特应性的风险高于男性。(3)小鱼比例越高，风险越低。(4)食用鸡蛋的频率越高，风险越低。结论：虽然没有发现大型海洋鱼类与特应性皮炎之间的关联，但在校正了性别和遗传决定因素的影响后，获得了一个新的发现，即小鱼的摄食频率降低了风险。另一项发现是，母亲在餐中不经常吃鸡蛋的孩子患这些疾病的风险更高。一种解释如下：因为鸡蛋通常是早餐，所以少吃鸡蛋可能意味着少做早餐。同样，小鱼通常作为晚餐，但比大鱼或肉更耗时，需要更先进的技术。因此，研究结果是一致的，母亲照顾更好的饮食可能会降低孩子患特应性皮炎的风险。少

1。I authored a chapter entitled "Evaluation of Measurement Error" in a medical book published by Asakura Shoten that includes part of the results obtained from the study. A Fortran program for the multivariate measurement error model was developed and uploaded.2。Touch-panel questionnaire system for the dining habit and the genetic factor was developed so that touching the display panel automatically accumulates the answers into an Access file. Questions are concerned with (A) Atopic dermatitis diagnosis, (B) Frequency of serving meat, small fish, large fish and eggs, (C) Frequently eating fish in Sushi, (D)3。About 80% of those who attended the health assessment service at the Nagasaki City Public Health Center voluntarily answered on the system. However, because it took about ten minutes to complete, some of them were not able to answer. It was concluded that the question paper was suitable for dealing with a number of people simultaneously.4。About 7% of 600 children suffered from atop … More ic dermatitis or resemblance.A multivariate logistic regression model reveals that (1)When the relative has atopy, asthma, or the allergic constitution, the risk of atopy is high. (2)Woman's risk of atopy is higher than that of a man. (3)The higher small fish's ratio is, the lower the risk is. (4)the higher the frequency of the egg serving is, the lower the risk is.Conclusion : Although association between a large ocean-ranging fish and atopic dermatitis was not found, a new finding was obtained that the feeding frequency of a small fish decreased the risk after correcting for the influence of sex and the hereditary determinant. Another finding is that children whose mothers serve eggs in meals less frequently are at higher risk for the diseases. An interpretation is as follows : Since eggs are usually served for breakfast, less frequency of egg serving may imply less cooking for breakfast. Similarly, small fish are usually served for dinner but are more time-consuming and require advanced technique than large fish or meats. Therefire, the findings are consistent that mothers who care for better meals may result in less risk for atopic dermatitis for their children. Less
