Prevalence and Treatment of Psoriasis in the United Kingdom

The epidemiology of psoriasis in the General Practice Research Database population is similar to that of other epidemiologic studies of psoriasis performed in the United Kingdom, the United States, and other Western countries. Psoriasis carries a substantial burden given its high prevalence and its associated need for prescription therapy. Additional studies are necessary to determine why the prevalence of psoriasis increases more rapidly in female patients and to determine why the prevalence decreases in patients 70 years and older.
