Exploring the interplay of atopic dermatitis severity with sleep and mental health: a case-control study in adult patients.

Atopic dermatitis (AD) is a chronic inflammatory skin disease often associated with non-atopic comorbidities. Recently, a severity-dependent relationship between AD and sleep/mental health diseases has been proposed. However, few studies investigated these comorbidities and their association with AD severity through validated questionnaires. This study aimed to use a set of validated instruments to assess the impact of AD on sleep and psychological disorders and estimate the association of itch and AD severity with sleep disorders and psychological symptoms, distinguishing between clinical-oriented and patient-oriented measures. We conducted a case-control study, recruiting 57 adult AD patients (mean age ± std. dev. 34.28 years ± 13.07; 27 males) matched for age and sex with 57 healthy adults (34.39 years ± 13.09; 27 males). To investigate the differences in sleep quality, insomnia, depression, and anxiety between the two groups, we performed independent sample t-Tests. Moreover, we conducted univariate linear regression analyses to examine the relationship between itch and objective/subjective severity of AD and sleep quality, insomnia, and psychological symptoms. AD patients reported lower sleep quality ( The study demonstrated poor sleep quality and high levels of insomnia, depression, and stress in AD patients, with an aggravated psychological status for adults with more severe skin disease. We suggest implementing a multidisciplinary approach to AD management/treatment that considers objective and subjective measures of disease severity.
