The objective of this study is to identify the contribution that selected 
demographic characteristics, health behaviors, physical health outcomes, and 
workplace environmental factors have on presenteeism (on-the-job productivity 
loss attributed to poor health and other personal issues). Analyses are based on 
a cross-sectional survey administered to 3 geographically diverse US companies 
in 2010. Work-related factors had the greatest influence on presenteeism (eg, 
too much to do but not enough time to do it, insufficient technological 
support/resources). Personal problems and financial stress/concerns also 
contributed substantially to presenteeism. Factors with less contribution to 
presenteeism included physical limitations, depression or anxiety, inadequate 
job training, and problems with supervisors and coworkers. Presenteeism was 
greatest for those ages 30-49, women, separated/divorced/widowed employees, and 
those with a high school degree or some college. Clerical/office workers and 
service workers had higher presenteeism. Managers and professionals had the 
highest level of presenteeism related to having too much to do but too little 
time to do it, and transportation workers had the greatest presenteeism because 
of physical health limitations. Lowering presenteeism will require that 
employers have realistic expectations of workers, help workers prioritize, and 
provide sufficient technological support. Financial stress and concerns may 
warrant financial planning services. Health promotion interventions aimed at 
improving nutrition and physical and mental health also may contribute to 
reducing presenteeism.
