title: The healthy worker effect in actively working communications workers.
abstract: The healthy worker effect is examined in a large population of actively working communications workers. The mortality experience of 338,306 white male workers at the American Telephone and Telegraph Company grouped by age, duration of service, and general cause categories is compared with the mortality experience of US white males in 1976. Observed were statistically significant and often substantial deficits in mortality among these active workers in almost all categories. For cancers and cardiovascular diseases, mortality ratios tended to decrease across age in the subgroups with longer service durations; these ratios consistently increased across duration of service in older ages. In subgroups with long service durations, the secondary selection of the healthy worker effect in this active worker population appears to increase with increasing age.
