Estimating the prevalence of chronic fatigue syndrome among nurses.
Jason, L A, Wagner, L, Rosenthal, S et al. · The American journal of medicine · 1998 · DOI
Quick Summary
This study looked at how many nurses have ME/CFS by sending questionnaires to two groups of nurses and then doing more detailed evaluations on those with CFS-like symptoms. The researchers found that nurses may get ME/CFS at higher rates than the general population, possibly because of job-related stress such as shift work, virus exposure, and workplace hazards. This suggests nurses might be at special risk for developing this illness.
Why It Matters
This study is important because it identifies nurses as a potentially high-risk occupational group for ME/CFS and highlights occupational stressors as possible contributing factors. Understanding which populations are at higher risk helps researchers identify common pathways to illness and informs workplace health and prevention strategies. The findings underscore that ME/CFS affects working professionals and has real occupational health implications.
Observed Findings
Estimated prevalence of ME/CFS in nurses: 1,088 per 100,000
Two nurse samples were recruited and screened via mailed questionnaires
Nurses with CFS-like symptoms underwent structured clinical interviews and medical record review
Occupational stressors identified: shift work, viral exposure, and workplace accidents
Physician review team was used to confirm CFS diagnoses among suspected cases
Inferred Conclusions
Nurses may represent a high-risk group for developing ME/CFS compared to the general population
Occupational factors in nursing—particularly shift work and infectious exposure—may increase vulnerability to ME/CFS
Healthcare workers warrant inclusion in future ME/CFS epidemiological research and occupational health monitoring
Remaining Questions
Does the elevated prevalence in nurses reflect true increased susceptibility, greater occupational exposures, survivor bias, or detection differences?
What is the actual prevalence of ME/CFS in the general population at the time of this study for comparison?
Which specific occupational stressors (viral exposure, shift work, accidents, or others) are most strongly associated with ME/CFS development?
What This Study Does Not Prove
This study does not prove that occupational stressors cause ME/CFS—it only shows an association. The cross-sectional design cannot establish causation or temporal sequence. The study also does not determine whether higher prevalence in nurses reflects true biological susceptibility, increased exposure to triggering factors, or occupational selection effects (people with ME/CFS leaving nursing).
