Kondo's "Incidence of Minamata Disease in Communities along the Agano River, Niigata, Japan (Jap. J. Hyg. 51: 599-611; 1996)" is critically reviewed. The data of the article were obtained from most of the residents living in the Agano river villages where Minamata disease was discovered in June, 1965. However, sampling proportions were much different between in the population base and in the cases. The method of identification of cases from the data and the reason for the difference were not clearly demonstrated. The citations of reference articles are insufficient despite the fact that other epidemiologic studies on methyl-mercury poisoning have been reported not only in Japan, but also around the world. His"analysis of the recognized patients" is erroneous. Both the sampling scheme of information of hair mercury and the modeling of the analysis are based on Kondo's arbitrary interpretation, not on epidemiologic theory. His "analysis of the rejected applicants" is also erroneous. His calculations of the attributable proportion are incorrect and self-induced in both the assignments of data and analysis of data. Kondo has failed to study the epidemiologic theories in light of changes in the field. Therefore, his article is lacking in epidemiologic theory, a logical base and scientific inference.<BR>In Japan, epidemiologic methodology has rarely been used in studies on Minamata Disease in either Kumamoto and Niigata. The government has used neurologically specific diagnosis besed on combinations of symptoms to judge the causality between each of symptoms and methyl-mercury poisoning. Epidemiologic data obtained in Minamata, Kumamoto in 1971 indicate that the criteria set by the government in 1977 have produced much more false-negative patients than false-positive patients. As a result, a huge number of symptomatic patients, including those with peripheral neuropathy or with constriction of the visual field, did not receive any help or compensation until 1995. The authors emphasize that the causal relationship between each symptom and methyl-mercury exposure should be reevaluated epidemiologically in Japan.

Changes of causal inference concepts in medicine, especially those having to do with chronic diseases, were reviewed. The review is divided into five sections. First, several articles on the increased academic acceptance of observational research are cited. Second, the definitions of confounder and effect modifier concepts are explained. Third, the debate over the so-called "criteria for causal inference" was discussed. Many articles have pointed out various problems related to the lack of logical bases for standard criteria, however, such criteria continue to be misapplied in Japan. Fourth, the Popperian and verificationist concepts of causal inference are summarized. Lastly, a recent controversy on meta-analysis is explained. Causal inference plays an important role in epidemiologic theory and medicine. However, because this concept has not been well-introduced in Japan, there has been much misuse of the concept, especially when used for conventional criteria.

国内では大気汚染の健康影響を評価した疫学研究は依然として少ない為、下記目的を達成するために研究を行った。①短期曝露と疾病罹患の関連評価、②短期曝露と疾病別死亡の関連評価、③大気汚染曝露と周産期指標の関連評価、④大気汚染曝露と児の疾病罹患との関連評価。結果として、①では短期曝露により、循環器疾患、呼吸器疾患、心停止による救急搬送のリスクが上昇していた。②においては、日々の二酸化硫黄の濃度と疾病別死亡との関連を認めた。③に関しては、曝露モデルの検討を行っており、更なるデータ蓄積と解析を行う予定である。④に関しては、妊娠中の曝露は満期低出生体重児を増加させ、発達にも影響を及ぼしていた。

本研究の目的は、住民と意思決定者に活動の必要性と成果を見せる公衆衛生看護技術を構築し、それを習得する学習プログラムを開発することである。2011年度は、「見せる公衆衛生看護技術」を定義し、①活動の必要性を見せる技術、②活動の成果を見せる技術、③保健師の存在価値を見せる技術について内容を体系化、2012年度はそれをもとにテキスト「見せる公衆衛生看護技術」を作成、2013年5月に出版(岡山大学出版会)。2013年度はテキストを用いた教育プログラムを検討・試行した。2014年度には成果普及に向けたWEB教材を作成・公開した(http://wwwmiseru.fhs.okayama-u.ac.jp)。
