Background: Evidence demonstrates that individuals with atopic eczema (eczema) have increased depression and anxiety; however, the role of ethnicity in these associations is poorly understood. We aimed to investigate whether associations between eczema and depression or anxiety differed between adults from white and minority ethnic groups in the UK. Methods: We used UK Clinical Practice Research Datalink GOLD to conduct matched cohort studies of adults (≥18 years) with ethnicity recorded in primary care electronic health records (April 2006‐January 2020). We matched (age, sex, practice) adults with eczema to up to five adults without. We used stratified Cox regression with an interaction between eczema and ethnicity, to estimate hazard ratios (HRs) for associations between eczema and incident depression and anxiety in individuals from white ethnic groups and a pooled minority ethnic group (adults from Black, South Asian, Mixed and Other groups). Results: We identified separate cohorts for depression (215,073 with eczema matched to 646,539 without) and anxiety (242,598 with eczema matched to 774,113 without). After adjusting for matching variables and potential confounders (age, sex, practice, deprivation, calendar period), we found strong evidence (p < 0.01) of ethnic differences in associations between eczema and depression (minority ethnic groups: HR = 1.33, 95% CI = 1.22,1.45; white ethnic groups: HR = 1.15, 95% CI = 1.12,1.17) and anxiety (minority ethnic groups: HR = 1.41, 95% CI = 1.28,1.55; white ethnic groups: HR = 1.17, 95% CI = 1.14,1.19). Conclusions: Adults with eczema from minority ethnic groups appear to be at increased depression and anxiety risk compared with their white counterparts. Culturally adapted mental health promotion and prevention strategies should be considered in individuals with eczema from minority ethnic groups. [ABSTRACT FROM AUTHOR]

Background: Atopic dermatitis (AD) may be associated with an increased burden of neuropsychiatric outcomes such as anxiety and depression, but longitudinal data on the impact of AD severity is lacking, and a comprehensive assessment of neuropsychiatric disease in adults with AD is needed. Objectives: Determine risk of incident neuropsychiatric disease among adults with AD by severity. Methods: A cohort study using electronic health records data from UK general practices from 1994 to 2015. Adults (≥18 years) with AD were matched on age, practice and index date to patients without AD. AD severity was categorized using treatments and dermatology referrals. Outcomes were incident anxiety, depression, bipolar disorder, schizophrenia, attention‐deficit/hyperactivity disorder (ADHD), autism, obsessive‐compulsive disorder (OCD), suicidality and completed suicide. Results: Comparing 625,083 adults with AD to 2,678,888 adults without AD, AD was associated with higher risk of anxiety [HR 1.14 (1.13–1.15)], depression [1.14 (1.13–1.15)] and OCD [1.48 (1.38–1.58)] across all severities. Mild or moderate AD was also associated with higher risk of autism, ADHD, bipolar disorder and suicidality. Conclusions: Atopic dermatitis is associated with a higher risk of multiple neuropsychiatric conditions, but these risks differ by specific condition and AD severity. Clinicians should inquire about mental health in patients with AD. [ABSTRACT FROM AUTHOR]
