There have been many epidemiological and clinical researches on
chronic fatigue (CF) and chronic fatigue syndrome (CFS) since the
1990s, but such studies have been quite limited in Korea.
The aim of this study was to investigate the point prevalence of
CF and CFS in patients who visited community-based eight primary
care clinics in Korea.
The study subjects were 1,648 patients aged 18 yr and over who
visited one of eight primary care clinics in Korea between the 7th
and 17th of May 2001.
The physicians determined the status of the subjects through fatigue-related
questionnaires, medical history, physical examination, and laboratory
The subjects were categorized into no fatigue, prolonged fatigue,
CF and then CF were further classified to medically explained CF
(Physical CF and Psychological CF) and medically unexplained CF
(CFS and idiopathic chronic fatigue).
The point prevalence of CF and CFS were 8.4% (95% CI 7.1-9.7%)
and 0.6% (95% CI 0.2-1.0%).
Medically explained CF was 80.5% of CF, of which 57.1% had psychological
The clinical characteristics of CFS were distinguished from explained
CF. CF was common but CFS was rare in community-based primary care
settings in Korea.
