Thoroughly modern worries: the relationship of worries about modernity to reported symptoms, health and medical care utilization.
Petrie, K J, Sivertsen, B, Hysing, M et al. · Journal of psychosomatic research · 2001 · DOI
Quick Summary
This study looked at whether worries about modern health threats (like pollution, food safety, and radiation) are linked to symptom reporting and chronic fatigue syndrome (CFS). Researchers surveyed over 8,000 people and found that those with higher worries about modernity reported more physical symptoms, food intolerances, and CFS diagnoses. The study suggests that health anxiety about modern threats may influence how people interpret body signals and perceive their health.
Why It Matters
This study is relevant because it suggests psychological and health belief factors may influence symptom reporting and CFS diagnosis rates. Understanding how modern health anxieties shape symptom interpretation could inform better assessment of ME/CFS and help distinguish between symptom severity and perception-driven illness reporting.
Observed Findings
Individuals with high modern health worries reported significantly more somatic complaints than those with lower worries.
CFS was reported at higher rates among those with high modern health worries in both study populations.
Food intolerance reports were more common in those with elevated modern health worries.
Modern health worries were associated with increased use of alternative health practitioners rather than conventional medical care.
The structure of modern health worries identified four main components: environmental pollution, toxic interventions, tainted food, and radiation.
Inferred Conclusions
Modern health worries influence how individuals interpret and report somatic symptoms.
Health anxiety about modernity may play a role in the development or persistence of functional disorders like CFS.
MHW may shape healthcare-seeking behavior, driving patients toward alternative practitioners.
Concerns about modernity may undermine overall health perceptions independent of objective health status.
Remaining Questions
Does health worry about modernity causally contribute to CFS symptom development, or does CFS lead to heightened health worries?
What This Study Does Not Prove
This cross-sectional study cannot establish causality—it shows correlation only and cannot determine whether health worries cause CFS symptoms, CFS causes health worries, or whether both are driven by a third factor. The study also does not establish objective biomarkers for CFS or prove that MHW explains ME/CFS etiology. Additionally, findings from 2001 may not reflect current understanding of ME/CFS pathophysiology.

About the PEM badge: “PEM required” means post-exertional malaise was an explicit required diagnostic criterion for participant inclusion in this study — not that PEM was studied, observed, or discussed. Studies using criteria that do not require PEM (e.g. Fukuda, Oxford) are tagged “PEM not required”. How the atlas works →
