Abstract
Fatigue and excessive daytime sleepiness (EDS) were often regarded as having almost similar meaning in routine daily life. However, these two terms are strictly distinct concepts. The effect on depression between EDS and fatigue, which coexist depending on the situation or exist individually. We aimed to investigate both fatigue and EDS were classified in detail to determine which is more related to depression in the general population. A total of 2,493 participants (female: 1,257) (47.90 ± 0.33 years old) were investigated nationwide, across 15 South Korean districts using face-to-face interviews survey. Fatigue, EDS, and depression were evaluated using the Fatigue Severity Scale (FSS), Epworth sleepiness scale (ESS), and Patient Health Questionnaire-9 (PHQ-9), respectively. The covariates such as sleep habits and socio-behavioral factors were included. The prevalence of depression (PHQ-9 ≥ 10) was 8.42% (n = 210). Fatigue (FSS ≥ 36) was 30.8% (n = 767). EDS (ESS ≥ 11) was 15.3% (n = 382). The prevalence of depression was following four categories; EDS with fatigue (E+F+) (n = 67, 31.9% vs. 7.3%) (P < 0.001), fatigue without EDS (E-F+) (n = 71, 33.8% vs. 20.3%) (P < 0.001), EDS without fatigue (E+F-) (n= 16, 7.6% vs. 5.8%) (P = 0.294), and absence of fatigue and EDS (E-F-) (n = 56, 26.7% vs. 66.6%) (P < 0.001). After adjusting for covariates, the presence of depression (E-F-, reference) was associated with E+F+ (OR 8.804, 95% CI 5.818-13.321), E-F+ (OR 3.942, 95% CI 2.704-5.747), and E+F- (OR 2.812, 95% CI 1.542-5.131). We additionally performed logistic regression according to two categories. There was no significant difference of prevalence of depression between E+F- (reference) and E-F+ (OR 1.399, 95% CI 0.760-2.575). Although fatigue and EDS were associated with depression regardless of the presence of each other. But we did not find out which is more related with depression.
Fatigue and excessive daytime sleepiness are both associated with depression, but there is no clear distinction between their prevalence in the general population.
