The fundamentals of epidemiology and ethics in science

Environ Health Prev Med The fundamentals of epidemiology and ethics in science Hyogo Horiguchi 0 Dear Editor 0 0 Department of Hygiene, Kitasato University School of Medicine , 1-15-1 Kitasato, Minami-ku, Sagamihara, Kanagawa 252-0374 , Japan - I appreciate the response to my comments on the article by Ilmiawati et al. [ 1 ] published in Environ Health Prev Med from the author. However, it was not convincing in terms of the fundamentals of epidemiology and ethics in science. Again, epidemiology is essentially a comparative discipline, requiring the study of different places or different groups of people [ 2 ]. This is one of the fundamental concepts and procedures of epidemiology, and the author seems to understand this. To verify ‘‘the hypothesis that children in Asahikawa may eat less marine food, and different types of fish from ones in other areas in Japan’’, it is, as a matter of course, necessary to investigate other areas in Japan and present evidence for it. In addition, the data in this study were compared with those of a national representative of US children from NHANES or other developed countries, meaning that the author considered the children from Asahikawa City as representative of Japan, as ‘‘no Japanese representativeness can be delineated without comparing other nationality’’. The author insisted that the interference of the high level of urinary molybdenum with the measurement of urinary cadmium by inductively coupled plasma mass spectrometry (ICP-MS) is negligible, but it is contradictory to what the author himself reported previously [ 3 ].
