Key clinical point: Individuals with major depressive disorder (MDD) have lower sleep quality (SQ) vs. those with burnout syndrome (BS); a bidirectional association is seen between MDD and SQ, whereas BS is predictive for SQ but not vice versa.
Major finding: SQ was lower in individuals with MDD vs. those with BS (Pittsburgh Sleep Quality Index [PSQI], 9.8 vs. 8.2); those with comorbid MDD and BS had the lowest SQ (PSQI, 10.7). The risk of sleep disorders (SDs) was 2.59 and 1.57 times higher with MDD and BS, respectively. The longitudinal risk of SDs was 2.03 times higher with MDD, but not with BS. Individuals with SDs were at 2.02 times higher risk of MDD, but not of BS.
Study details: This longitudinal study identified participants from the Dresden Burnout Study and categorized them into 4 groups (BS, n = 339; MDD, n = 395; comorbidity group, n = 436; control group, n = 3,245).
Disclosures: This study was supported by the TU Dresden’s Institutional Strategy. The authors declared no conflicts of interest.
