This chapter provides some scientific background of risk assessment and sets up some of the institutional questions concerning the appropriate evidentiary standards needed within torts and administrative law to establish the requisite harms or risks of harm. The discussion here focuses on animal bioassays and human epidemiological studies, two aspects of carcinogen risk assessment relied upon in regulatory institutions to ascertain risks to human beings. The best evidence that proves that a substance causes cancer to human beings is provided by well-done epidemiological studies with large samples and sufficient follow-up. However, the chapter begins by considering animal studies, which is the evidence much more frequently relied upon by regulatory agencies, although it is less typically used in tort law and some jurisdictions give it little credence. There are uncertainties in animal bioassays which are large enough such that two different researchers using exactly the same data points from an animal study can come to much different conclusions.Less

Epidemiological studies have apparently distinct designs but are unified by their common goal to understand the frequency and causes of disease, by their strategy of seeking associations between exposures (potential causes) and outcomes (disease), by their utilization of the survey method, and by their basis in defined populations. This chapter discusses study design and analysis. Topics covered include classifications of study design; case series, cross-sectional study, case-control study, cohort study, trials, and data analysis and interpretation.Less

This chapter traces the development of the epidemiology of cardiovascular disease (CVD). Formal epidemiological research in cardiovascular diseases took several forms, beginning in 1948. The prototype and icon of international investigations was the Framingham Heart Study. The explosion of prospective studies from 1948 onwards, the modern era of research from 1972 to the present, and conceptual evolution in CVD epidemiology are discussed.Less

This chapter serves as a guide for developing a course in psychiatric epidemiology; that is, epidemiological methods applied to the study of psychiatric disorders rather than the epidemiology of specific psychiatric disorders. Methodological issues particularly relevant for these pathologies are emphasized, leaving the delineation of the substantive content of different mental disorders to the instructor's interests and expertise. This course does not need to assume prior training in psychiatry or psychopathology, and can be oriented to students at different educational levels. It is expected that students enrolled in this type of course have an interest in public health, medicine or psychology.Less

The cost, complexity, and risk of selection bias often associated with primary data collection has led to the use of disease registries and databases as an alternative data source for studies of many epidemiological and clinical questions. Medical registries and administrative databases are attractive options. They often contain information on large study populations, and they can provide information on exposures, disease outcomes, and some potential confounding factors for subjects in those populations. Thus medical databases can be very useful for the efficient study of etiologic associations in large populations, and for the evaluation of utilization, effectiveness and safety of medical interventions in clinical settings. This chapter presents an approach for teaching use of routine medical databases covering teaching objectives, teaching method and format, and assessing students' achievements.Less

This chapter introduces the ways in which data are manipulated, with a warning that the end results are often artificial measures that change (and sometimes distort) the perception and interpretation of risk, a matter of utmost concern to a science where communication between researchers, health professionals, and the public is critically important. Topics discussed include proportional morbidity or mortality ratio; relative risk; measurements to assess the impact of a risk factor in groups and populations; presentation and interpretation of epidemiological data in applied settings; and avoidable morbidity and mortality and life-years lost.Less

This chapter utilized the central epidemiological strategy — comparison of populations — to discuss bias. Bias, in an epidemiological context, arises when errors affect comparison groups unequally. Since this is often the case, perhaps always the case, bias is a central issue in epidemiology. Classification of error and bias and a practical application of the research chronology schema are discussed.Less

Biomarkers are increasingly being incorporated into epidemiologic studies of cancer etiology, often referred to as molecular epidemiology. This chapter focuses on the use of biomarkers in the context of etiologic research. It begins with a discussion of the development and characterization of biomarkers for use in epidemiologic studies, with a particular emphasis on understanding the components of variance and their impact on estimates of disease risk. It then discusses key issues in the use of exposure, intermediate end points, genetic susceptibility, and tumor biomarkers; and reviews the main epidemiologic study designs that use biomarkers. The chapter concludes with comments on collecting and processing biologic samples for use in molecular epidemiology studies.Less

The exposure to any pollutant is determined by the concentration of the pollutant in the environment, its specific character, and the duration and frequency of contact. Estimates of these characteristics can be obtained instrumentally (i.e., using a monitoring device), via questionnaires, through direct observation, or through the use of biomarkers. This chapter focuses on the measurement of personal exposure with instruments or biomarkers. Although personal monitoring is labour-intensive and expensive, it remain a valuable technique because it can dramatically improve exposure assessment in epidemiological studies, thus adding to the scientific credibility of the studies.Less

This chapter addresses some of the issues affecting the interpretation of spatial epidemiological studies. It separates the two concepts of bias and confounding. In general, bias and confounding are major problems affecting all observational studies, and are not special to spatial studies. However, there are several forms of bias that are specific to spatial studies. These include selection effects, denominator bias, exposure inaccuracy bias and the errors-in-variables problem, spatial dependency, significance tests, and ecological bias. The chapter also discusses socio-economic confounding as this is a major potential source of bias in spatial epidemiology.Less
