Multilingual Digital Search Behavior Reveals Cultural Disparities in Vitiligo Information Needs in Germany

Vitiligo can cause substantial psychosocial distress, including stigma, depression, and social exclusion. Cultural factors shape disease perception and information needs. Online search queries provide real-time indicators of unmet public interests. We investigated language- and culture-associated differences in vitiligo-related online information seeking in Germany to inform culturally competent dermatologic care.

We conducted a retrospective observational study using anonymized data from the Google Ads Keyword Planner (October 2019-May 2023). Search terms related to vitiligo were analyzed in six languages (German, Turkish, Arabic, English, Russian, Polish), representing the most commonly spoken languages in Germany. Keywords were thematically categorized and comparatively analyzed across languages.

A total of 7.8 million vitiligo-related search queries were identified, with the majority in German. "General information" was the most frequently searched category, except in Arabic, where "treatment options" ranked highest. Treatment queries in Turkish and Arabic more frequently mentioned alternative therapies and home remedies than specific evidence-based treatments. Notable cross-language differences emerged in searches for camouflage, depigmentation, faith-related coping, and psychosocial burden.

Online search behavior reveals both shared and language-specific interests about vitiligo. Observed language patterns are hypothesis-generating and may reflect differences in information access, healthcare navigation, and language barriers rather than inherent cultural preferences. Language-specific patterns highlight the need for culturally sensitive communication, multilingual patient education, and inclusive care models in dermatology to promote health equity.
