Purpose
Poor sleep and mood may be predisposing factors for acne. We aimed to investigate the associations between acne and sleep quality, circadian preferences, and mood.
Methods
This case–control study recruited patients with acne and age- and sex-matched healthy controls. We used the Investigator’s Global Assessment to evaluate acne severity and various validated questionnaires to measure sleep quality, daytime sleepiness, sleep apnea, circadian preference, and mood symptoms.
Results
A total of 81 patients with acne (age: 21.6 ± 5.0 years, 52% female) and 76 controls were recruited. Compared to controls, patients had a higher score on the Pittsburgh Sleep Quality Index (5.2 ± 2.6 vs. 4.1 ± 2.3, p = 0.008) and State–Trait Anxiety Inventory (State: 44.6 ± 9.7 vs. 40.6 ± 6.6, p = 0.003; Trait: 47.9 ± 8.2 vs. 45.3 ± 6.2, p = 0.03), and a lower score on a reduced version of the Morningness and Eveningness Questionnaire (13.9 ± 2.6 vs. 14.7 ± 2.3, p = 0.05) and Epworth Sleepiness Scale (7.4 ± 3.4 vs. 8.6 ± 3.6, p = 0.04). Acne severity was associated with sleep quality (β = 0.33), eveningness (β = 0.34), depression (β = 0.66), and anxiety (State: β = 1.73; Trait: β = 1.21), even when adjusted for education level and family history of acne.
Conclusion
Acne is highly associated with poor sleep and mood. Dermatologists are advised to attend closely to the psychological impact of acne. Improvements in sleep and mood may benefit the treatment of acne.
