Despite considerable research on chronic fatigue syndrome (CFS) and conditions associated with unexplained chronic fatigue (CF), little is known about their prevalence and demographic distribution in the population.
The present study describes the epidemiology and characteristics of self-reported CF and related conditions in a diverse urban community.
The study used a cross-sectional telephone screening survey of households in San Francisco, followed by interviews with fatigued and nonfatigued residents.
Respondents who appeared to meet case definition criteria for CFS, based on self-reported fatigue characteristics, symptoms, and medical history, were classified as CFS-like cases.
Subjects who reported idiopathic chronic fatigue (ICF) that did not meet CFS criteria were classified as ICF-like cases.
Screening interviews were completed for 8,004 households, providing fatigue and demographic information for 16,970 residents.
Unexplained CF was extremely rare among household residents<18 years of age, but was reported by 2% of adult respondents.
A total of 33 adults (0.2% of the study population) were classified as CFS-like cases and 259 (1.8%) as ICF-like cases.
Neither condition clustered within households.
CFS-and ICF-like illnesses were most prevalent among women and persons with annual household incomes below $40,000, and least prevalent among Asians. (...)
