A low level of health literacy is a predictor of corticophobia in atopic dermatitis

Le résumé fourni par la source

BACKGROUND: Topical corticosteroids (TCS) are the mainstay of treatment in atopic dermatitis (AD) flares. The fears and worries concerning TCS are known as corticophobia. Corticophobia is common in patients with AD and can lead to suboptimal TCS application and treatment failure. Health literacy (HL) may influence corticophobia. TOPICOP© and HLS-EU-PT questionnaires have been developed to evaluate corticophobia and HL, respectively. OBJECTIVE: Evaluate the relationship between corticophobia and the degree of HL in patients with AD. METHODS: Prospective cross-sectional study with AD patients followed at a Dermatology Department, between September 2019 and February 2020. Patients, or their parents (if patients had ≤ 15 years), were invited to answer TOPICOP© questionnaire, HLS-EU-PT questionnaire, and a disease characterization and demographic questionnaire. RESULTS: = 0.146). There was no statistical difference between TOPICOP© score and disease characteristics (disease severity, family history of AD or personal history of other atopic diseases). STUDY LIMITATIONS: Small and heterogenous cohort composed of patients and patients' parents. CONCLUSION: The degree of corticophobia is similar to the values reported in other studies. HL had an inverse correlation with corticophobia. Lower HL was shown to be a predictor of higher corticophobia. The promotion of health literacy is essential for the correct use of TCS and good control of AD.
