Document Summary
In this lecture, we will begin to study the ways in which we assess causal factors and risk factors for common chronic diseases such as cancer and cardiovascular disease. We"ve already seen that we cannot determine the risk factors by identifying the nature of the causal agent (such as is the case with a pathoetiological diagnosis). Recommended readings: this link is to a website devoted to scientific research and design. Although there are some deviations from standard definitions in their discussions, it is still an informative source for basic information regarding various types of research designs. http://explorable. com/research-designs. html. When we wish to establish the causal and risk factors determining variability in incidence rates of non-communicable diseases such as cancer and heart disease, we are asking which exposures increase disease risk? . Often, epidemiological evidence suggests the nature of the exposure. In this case, we then even more advanced questions such as:
