The healthy worker effect. Selection of workers and work forces.
本文探讨了就业人群健康状况优于一般人群的“健康工人效应”，指出除招聘筛选外，社会经济地位差异导致的劳动力选择也可能解释该效应。
The favorable health status of employed populations in comparison to that of the general population is often called the "healthy worker effect," and most researchers feel that it results from the selection of healthy individuals during the hiring process. However, other mechanisms may also contribute to the healthy worker effect. In particular, the healthy worker effect may reflect the selection, for epidemiologic study, of relatively advantaged workforces in terms of socioeconomic status and health. Evidence of differential health by socioeconomic status within the workforce is reviewed, and its possible role in the healthy worker effect is discussed.
