This study followed over 11,000 children born in 1970 into adulthood to understand what childhood factors might lead to developing ME/CFS later in life. Researchers found that people who were less active as children, had long-term health conditions in childhood, or were female had higher chances of developing ME/CFS by age 30. Importantly, childhood stress or psychological problems were not found to be risk factors, contrary to some earlier beliefs.
This study challenges the misconception that psychological problems in childhood cause ME/CFS, providing evidence that ME/CFS has roots in physical rather than purely psychiatric factors. Understanding true childhood risk factors helps shift focus toward biological mechanisms and may reduce harmful psychological stigma surrounding the condition. For patients, this validates that the condition is not caused by childhood stress or mental health issues.
This study cannot prove causation—it shows associations observed in one birth cohort but does not establish that lower childhood exercise directly causes ME/CFS. The study relies on self-reported diagnosis rather than clinical examination, which may not capture confirmed cases or may include misdiagnoses. Results from one birth cohort born in 1970 may not apply to all populations or time periods.
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 →
