Temporal relations between unexplained fatigue and depression: longitudinal data from an international study in primary care
Abstract
OBJECTIVE: Unexplained fatigue syndromes, such as chronic fatigue syndrome and neurasthenia, are strongly associated with depression, but the temporal nature of this association is not clear. METHODS: The authors examined this issue by using data from the World Health Organization collaborative study of psychological problems in general health care. Three thousand two hundred one subjects from 15 primary care centers in 14 countries were followed up for 12 months. The Composite International Diagnostic Interview was the main instrument used. Odds ratios and their 95% confidence intervals (CI) were calculated using logistic regression models adjusted for sociodemographic variables, physical morbidity and intercenter variability. RESULTS: Cases of depression were found to have an increased risk of developing a new episode of unexplained fatigue at follow-up with an adjusted odds ratio of 4.15 (95% CI = 2.64-6.54). Similarly, cases of unexplained fatigue were found to have an increased risk of developing a new episode of depression at follow-up with an adjusted odds ratio of 2.76 (95% CI = 1.32-5.78). Further adjustment for subthreshold symptoms at baseline weakened the reported associations, especially between fatigue and development of a new episode of depression, but these remained significant. CONCLUSIONS: The findings support the view that unexplained fatigue and depression might act as independent risk factors for each other.

Fatigue is strongly associated with depression, and longitudinal studies show fatigue is a risk factor for depression and vice versa.
“It is strongly associated with depression (Wessely et al., 1996; Bakshi et al., 2000; Kroencke et al., 2000; Pittion-Vouyovitch et al., 2006), and longitudinal studies have demonstrated that fatigue represents a risk factor for depression (and vice versa; Skapinakis et al., 2004).”

Longitudinal studies have shown that the causal relation between fatigue and depression is unlikely to be unidirectional, but that both act as independent risk factors for each other.

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.
