The association between COVID-19 lockdown and disease severity, quality of life, and mental health in patients with psoriasis: a cross-sectional study in Southwestern China

Our results revealed that COVID-19 lockdown had a measurable impact on disease severity, quality of life, and mental health in psoriasis patients. Many individuals experienced varying degrees of symptoms aggravation during the lockdown. The severity of psoriasis was negatively correlated with quality of life and positively correlated with depression symptoms, with older adult patients being particularly vulnerable to depression. These findings highlight the importance for dermatologists to integrate mental health assessment and support into routine psoriasis management.
