Background and Objective: Symptomatic dermographism (SD), the most common chronic inducible urticaria subtype, manifests as strip-shaped, pruritic wheals after skin friction. Conclusive data on its associated factors are limited, and direct comparisons between individuals with and without SD remain scarce. We aimed to identify factors associated with SD internationally. Methods: The PREVALENCE-D (Prevalence Estimation of Dermographism) study was an international cross-sectional survey conducted from 2021 to 2024 across 19 countries. An expert-designed questionnaire diagnosed SD and assessed potential associated factors. SD participants were defined as those who self-reported chronic recurrent urticarial dermographism with itch. Factors associated with SD were identified by comparing participants with and without SD. Results: Of 68,513 participants, 3101 had SD (female 73.3%). Their mean age was 40.2 ± 16.2 years. Key factors associated with SD included atopic dermatitis (adjusted odds ratio [aOR] 4.20, 95% confidence interval [CI] 3.62‒4.88) and allergic rhinitis (aOR 2.11, 95% CI 1.88‒2.37). Participants with at least one atopic condition (allergic rhinitis, atopic dermatitis, or asthma) were significantly more likely to have SD (aOR 2.70, 95% CI 2.47-2.95). Those with all three atopic conditions had a further increased likelihood of SD (aOR 7.75, 95% CI 5.31-11.29). Other associations included working and older age groups, female sex, dyslipidemia, and thyroid disease. Conclusions: Atopic dermatitis and allergic rhinitis emerged as the strongest correlates of SD, especially those with all three atopic conditions. Thus, allergic comorbidities should be assessed in SD patients. Further research is needed to clarify the pathophysiological relationship between these conditions and SD.
