This book is an introductory text intended for those people who need to know more about the scientific principles behind the study of the causes of disease occurrence. As most people spend a large part of their lives at work, and as some people may be at risk of being exposed to harmful substances at high levels, workers' protection should have a high priority. Studies in the workplace can help to identify causes of occupational diseases, and the outcome of such investigations should be applied when the effects of protective action are evaluated. The book argues that, in searching for occupational causes of disease, epidemiological principles should be used, even at the factory level. Applying strict logical principles to the collection of data concerning workers' experience with ill-health ensures that a useful insight is gained into the causes of disease, and that data are obtained in a format suitable for subsequent larger-scale studies.
'The simple, if occasionally simplistic, approach to the subject will lead the most timid reader to a sound understanding of the basic principles and in particular their application to day to day problems of medical practice...should be compulsory reading for all those who produce articles or programmes for the media on work-related and environmental health issues.'
