Psoriasis and Psoriatic Arthritis: Analysis of 2009-2011 Incidence Rates in Russian Federation
Tudy Objective: To conduct a comparative analysis of the incidence rates of psoriasis and psoriatic arthritis (PA) in Russia among adults and children and in urban and rural populations, including people who must have regular medical checkups. Study Design: This was a comparative study. Materials and Methods: We performed statistical and comparative analyses of the prevalence and incidence rates of psoriasis and PA among children and adults and in urban and rural populations, expressed as a rate per 100,000 people. The data were obtained from annual statistical reports submitted in 2009, 2010, and 2011, using Form No 12 Report on Number of Disease Events Reported in the Hospital's Catchment Area, developed by the Ministry of Health Care and Social Development. Results: An analysis of diseases detected in people who sought medical help showed that in Russia psoriasis is not the most frequent chronic skin and subcutaneous-tissue disorder: It is present in 3.5% of all patients with such disorders. Psoriasis is detected in adults twice as often as it is in children, and more often in urban rather than rural populations. Conclusion: These data suggest the need to implement new methods for collecting and reporting disease-incidence rates and managing psoriasis and PA.
