    TLDR Vitiligo is underreported in medical claims and is linked to certain skin types and autoimmune diseases.
    The study "Epidemiology of Vitiligo – A Dual Population-Based Approach" used two population-based approaches to understand the prevalence and associated conditions of vitiligo. The study involved 121,783 working individuals and 1,619,678 claims data from a large German statutory health insurance. The prevalence of vitiligo was found to be 0.77% in the working cohort and 0.17% in the claims data, indicating that vitiligo is more frequently observed in clinical exams than recorded in claims data. This suggests that many people with vitiligo do not seek medical help. The study also found that vitiligo was more common in people with fair skin type, ephelides and port-wine stains, and less common in people with acne and solar lentigines. Vitiligo was associated with several skin conditions and autoimmune diseases, including atopic dermatitis, psoriasis, alopecia areata, and other disorders of pigmentation. The study concludes that understanding the epidemiology of vitiligo can help in the development of effective treatment strategies.
