    Case-control study.

    Population and setting 

    Over 3 300 current employees in two state office buildings and employees in a comparable « control » building.

    Independent risk factors for fatigue lasting one month or longer were found to be Native American ethnicity (OR 2.4, CI 1.1,5.3), Hispanic ethnicity (OR 1.7, Cl 1.3,2.3), female sex (OR 1.5, Cl 1.2,1.9), gross household incomes of less than $50,000 (OR 1.3, Cl 1.1,1.6), and less than a college education (OR 1.3, Cl 1.1,1.6).
