Investigators made a cross-sectional analysis using electronic health records data for a demographically heterogeneous population-based sample of over 55 million patients in all four census regions the United States in order to understand the disease burden in chronic urticaria.
From the analysis of the available census data, they estimate that the overall chronic urticaria prevalence is 0,23% (or 230 patients per 100,000 adults). The adjusted prevalence in women was 310 per 100,000 adults, more than twice that of men (146 per 100,000 adults).
Patients aged 40-49 and 50-59 years old had a higher prevalence compared with all other age groups. Also, Caucasians had a lower prevalence of urticaria than African American and “other” people.
In conclusion, despite census data available may underestimate the burden of chronic urticaria, this team estimates that over 500,000 people have chronic urticaria in the United States, most of whom are women and adults over 40 years old.
