Abstract

Prevalence of functional somatic syndromes (FSS) in the general population varies with observed overlap between syndromes. However, studies including a range of FSS are sparse. We investigated prevalence and characteristics of various FSS and the unifying diagnostic construct bodily distress syndrome (BDS), and identified mutual overlap of the FSS and their overlap with BDS. We included a stratified subsample of 1590 adults from a randomly selected Danish general population sample (n = 7493). Telephonic diagnostic interviews performed by three trained physicians were used to identify individuals with FSS and BDS. Prevalence of overall FSS was 9.3%; 3.8% for irritable bowel, 2.2% for chronic widespread pain, 6.1% for chronic fatigue, 1.5% for whiplash associated disorders, and 0.9% for multiple chemical sensitivity. Prevalence of BDS was 10.7% where 2.0% had the multi-organ type. FSS were highly overlapping with low likelihood of having a “pure” type. Diagnostic agreement of FSS and BDS was 92.0%. Multi-syndromatic FSS and multi-organ BDS were associated with female sex, poor health, physical limitations, and comorbidity. FSS are highly prevalent and overlapping, and multi-syndromatic cases are most affected. BDS captured the majority of FSS and may improve clinical management, making the distinction between multi- and mono-syndromatic patients easier.

  • There is substantial overlap of symptoms between various types of functional somatic syndromes, indicating that the syndromes are not entirely independent conditions but different representations of a family of related disorders.

    “Nevertheless, a substantial overlap of symptoms has been shown between the various types of FSS, indicating that the syndromes are not entirely independent conditions but different representations of a family of related disorders [8].”

    From Internet-delivered treatment for patients suffering from severe functional somatic disorders: Protocol for a randomized controlled trial (2023) · cites this paper as [8]

    The Introduction states that symptoms substantially overlap across FSS diagnoses and suggests the syndromes may be different representations of a common phenomenon or belong to a family of related disorders. The Results also document substantial overlap. The citing sentence presents the proposed relationship more definitively and combines the paper’s two alternative interpretations. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • There is empirically proved overlap in symptomatology between patients with various FSS.

    “The clinical rationale for a generic treatment approach is further supported by the empirically proved overlap in symptomatology between patients with various FSS [38, 39].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
