Inpatients with acne or rosacea had increased odds of comorbid mental health (MH) disorders, according to a recent study. In particular, there was an increased number of hospital admissions secondary to a primary MH disorder with coexistent acne/rosacea. Furthermore, MH comorbidities were associated with considerable excess costs among inpatients with acne or rosacea. Data were examined from the 2002–2012 US National Inpatient Sample, comprising a sample of ~20% of all US pediatric and adult hospitalizations (n=87,053,155 admissions). Researchers found:

• A diagnosis of ≥1 MH disorder was much more common among all inpatients with vs those without a diagnosis of acne (43.7% vs 20.0%, respectively) and rosacea (35.1% vs 20.0%, respectively).
• In multivariable logistic regression models controlling for sex, age, race/ethnicity, and insurance status, acne (adjusted OR=13.02) and rosacea (adjusted OR=1.70) were associated with significantly higher odds of a primary admission for an MH disorder (13 and 8, respectively, of 15 MH disorders examined).
• Both acne and rosacea were associated with higher risk of mood, anxiety, impulse control, and personality disorders, and with >$2 million of excess mean annual costs of hospitalization for MH disorders in the US.
