Chronic fatigue syndrome prevalence is grossly overestimated\u00a0using Oxford criteria compared to Centers for Disease Control\u00a0<\/a>(Fukuda) criteria in a U.S. population study, by\u00a0James N. Baraniuk in<\/span> Fatigue: Biomedicine, Health & Behavior [<\/em>Published online: 21 Jul 2017]<\/p>\n

Background:
\nResults from treatment studies using the low-threshold Oxford criteria for recruitment may have been overgeneralized to patients diagnosed by\u00a0more stringent chronic fatigue syndrome (CFS) criteria.<\/p>\n

Purpose:
\nTo compare the selectivity of Oxford and Fukuda criteria in a U.S.\u00a0population.<\/p>\n

Methods
\nFukuda (Center for Disease Control (CDC)) criteria, as operationalized\u00a0with the CFS Severity Questionnaire (CFSQ), were included in the\u00a0nationwide rc2004 HealthStyles survey mailed to 6175 participants who\u00a0were representative of the U.S. 2003 Census population. The 9\u00a0questionnaire items (CFS symptoms) were crafted into proxies for Oxford\u00a0criteria (mild fatigue, minimal exclusions) and Fukuda criteria (fatigue\u00a0plus \u22654 of 8 ancillary criteria at moderate or severe levels with\u00a0exclusions). The comparative prevalence estimates of CFS were then\u00a0determined. Severity scores for fatigue were plotted against the sum of\u00a0severities for the eight ancillary criteria. The four quadrants of\u00a0scatter diagrams assessed putative healthy controls, CFS, chronic\u00a0idiopathic fatigue (CIF), and CFS-like with insufficient fatigue\u00a0subjects.<\/p>\n

Results:
\nThe Oxford criteria designated CFS in 25.5% of 2004 males and 19.9% of\u00a01954 females. Based on quadrant analysis, 85% of Oxford-defined cases\u00a0were inappropriately classified as CFS. Fukuda criteria identified CFS\u00a0in 2.3% of males and 1.8% of females.<\/p>\n

Discussion
\nCFS prevalence using Fukuda criteria and quadrant analysis was near the\u00a0upper limits of previous epidemiology studies. The CFSQ may have utility\u00a0for on-line and outpatient screening. The Oxford criteria were untenable\u00a0because they inappropriately selected healthy subjects with mild fatigue\u00a0and CIF and mislabeled them as CFS.<\/p>\n
