| Abstract |
The issue of age as a potential confounding factor in occupational epidemiology is explored. It is concluded that in most situations age is important as a potential confounder and should be controlled to avoid a distortion in the effect estimate. Age, in other instances, can affect the mode of action of a given exposure, and in these instances it should not be treated as extraneous, rather its interaction with exposure should be explicitly considered in analysis and interpretation of results. In studies lasting for long periods, analytical techniques should make allowance for aging, which is in itself an indicator of the time related changing risk of many diseases. Finally, age is one of the reasons why relative risks are more commonly used as effect measures rather than risk differences: the relative risks have greater stability over age strata. |
