The purpose of this study was to quantitatively assess fatigue in several United States Air Force USAF shift worker populations. An epidemiological cross-sectional survey of 172 USAF personnel was conducted from October 2004 to May 2005. The study sample was recruited from 4 different USAF populations using some form of shift work to include irregular, rotational, or fixed shifts. Self-reported average daily sleep and steep quality did not correlate with fatigue. Fatigue was greater in the unmanned aircraft versus the manned aircraft squadron irrespective of career field implying organizational work-related factors such as workload or manpower were underlying this observation. Crewmembers and maintenance personnel reported equal levels of fatigue, suggesting crewmember workrest guidelines may not be useful for mitigating fatigue associated with shift work. Shift workers were equally fatigued whether at home base or deployed in current military operations, reinforcing the intrinsically fatiguing nature of shift work.
