Abstract
ObjectivesThis study aims to provide a comprehensive analysis of the age-dependent risk of psoriatic arthritis (PsA). For this purpose, it focuses on the varying incidences within the different age groups.MethodsThe data were collected as part of the morbidity-based risk adjustment of the statutory health insurance companies in Germany. This survey recorded the International Statistical Classification of Diseases and Related Health Problems (ICD)-coded diagnoses of 65 million German citizens. Our population-based study used these raw data to calculate the prevalence of PsA in the first step. Subsequently, we employed a new approach for the estimation of the age-specific and sex-specific incidence of PsA.ResultsThe age-specific and sex-specific incidence of PsA showed a continuous increase with rising age until it peaked slightly before the age of 60 and declined thereafter. The maximum value was higher in women (40 per 100 000 py) than in men (30 per 100 000 py). Furthermore, the incidence rate tends to climb over the survey period.ConclusionsThe data sets identified an unexpected high incidence. A meta-analysis by Scotti et al and other recent population-based studies served as a reference for the comparison. The pattern of the age-specific incidence illustrated that the risk for PsA disease shows considerable variations depending on age.
