There has been some suggestion that men first hired during World War I
I do not show the typical healthy worker effect and may have been more
unhealthy than their counterparts who entered military service. We ha
ve studied 41,000 workers at six plants to determine whether men hired
during World War II had higher mortality than men hired just before o
r after WWII. No evidence was found of any ''unhealthy WWII worker'' e
ffect.
