Obesity Research in Occupational Safety and Health

Abstract

Obesity is an emerging health problem among the workforce. This review examined the published literature in the last decade presented in prominent human factors and occupational safety and health journals to map out the current state of the research and direct future work. Overall, 44 studies were identified, out of which 27% focused on general effects of obesity on work performance, disability or occupational injury and 73% studied hypotheses regarding the effect of obesity on functional capacity, balance and performance of specific tasks. While over 90% of general studies suggest some significant adverse effect, only ~47% of specific studies report such results. While obesity co- occurs with chronic conditions such as diabetes or cardio-respiratory issues, laboratory based studies which exclude subjects with comorbidities may fail to fully manifest obesity effects. With only four studies identified that investigated an interaction of obesity with other personal or job-related health risks, future research in this regard is warranted.
