Sample text

PH efforts that address only a few of the most apparently important component causes can have significant success in reducing the incidence of a disease; it is part of the job of EPDM to help identify those important causes. SUMMING ATTRIBUTABLE FRACTIONS OF CAUSES FOR DISEASES One can thus view each causal pie as a set of interacting causal components. This model provides a biological basis for a concept of interaction that is distinct from the usual biostatistical view of interaction (Ephron, 1984).

3%, are attributable to cigarette smoking among those who both smoke cigarettes and drink alcohol. 7%, to the causal role of alcohol drinking. 7% to alcohol drinking among those who are exposed to both? Yes—because some cases are counted more than once. Also, smoking and alcohol interact in some cases of head/neck cancer, and these cases are attributable both to cigarette smoking and to alcohol drinking. One consequence of interaction is that the proportions of disease attributable to various component causes seldom sum to exactly 100%.

Apparently, there are some people who, by virtue of their genetic makeup or previous experience, are susceptible to the ill effects of smoking, and others who are not (they sometimes are known as the tough rats, in reference to laboratory-animal experiments). 2 (Rothman & Greenland, 2005). In this diagram: ■ Each set of component causes represented is minimally sufficient to produce the disease. 34 2. RESEARCH AND DESIGN IN EPIDEMIOLOGY AND PUBLIC HEALTH ■ Each component cause is a necessary part of that specific causal mechanism.
