The Fukuda et al. (1994) criteria for chronic fatigue syndrome (CFS) specifies that a symptom can only be included within a diagnosis if it is experienced concurrently or following the onset of fatigue. In order to investigate this issue, participants provided information on persisting symptoms (lasting greater than six months) and whether those symptoms occurred prior to, concurrently, or following the onset of their fatigue. More symptoms were experienced after the fatigue onset than prior to the fatigue onset; however, a considerable number of participants reported experiencing persisting symptoms prior to the onset of CFS. Particularly, rates of hay fever and asthma were higher prior to the illness. Investigating symptoms prior to the onset of the illness might provide investigators with ways to better understand the etiology of this illness.
福田等人（1994年）提出的慢性疲劳综合征（CFS）标准规定，只有当一种症状在疲劳出现时或之后同时出现，才可以纳入诊断。为了研究这个问题，参与者提供了持续症状（持续超过六个月）的信息，以及这些症状是在疲劳发作之前、同时还是之后出现的。疲劳发作后出现的症状比疲劳发作前更多；然而，相当多的参与者报告在慢性疲劳综合征发作之前就经历了持续症状。特别是，花粉热和哮喘的发病率在患病之前更高。研究疾病发作前的症状可能会为研究人员提供更好地理解这种疾病病因的方法。
