{"doi":"10.1002/art.41741","title":"The Epidemiology of Psoriatic Arthritis Over Five Decades: A Population‐Based Study","abstract":"OBJECTIVE: To determine the incidence of psoriatic arthritis (PsA) in a US population and describe trends in incidence and mortality over 5 decades. METHODS: The previously identified population-based cohort that included Olmsted County, Minnesota residents ≥18 years of age who fulfilled PsA criteria during 1970-1999 was extended to include patients with incident PsA during 2000-2017. Age- and sex-specific incidence rates and point prevalence, adjusted to the 2010 US White population, were reported. RESULTS: There were 164 incident cases of PsA in 2000-2017 (mean ± SD age 46.4 ± 12.0 years; 47% female). The overall age- and sex-adjusted annual incidence of PsA per 100,000 population was 8.5 (95% confidence interval [95% CI] 7.2-9.8) and was higher in men (9.3 [95% CI 7.4-11.3]) than women (7.7 [95% CI 5.9-9.4]) in 2000-2017. Overall incidence was highest in the 40-59 years age group. The incidence rate was relatively stable during 2000-2017, with no evidence of an overall increase or an increase in men only (but a modest increase of 3% per year in women), compared to 1970-1999 when a 4%-per-year increase in incidence was observed. Point prevalence was 181.8 per 100,000 population (95% CI 156.5-207.1) in 2015. The percentage of women among those with PsA increased from 39% in 1970-1999 and 41% in 2000-2009 to 54% in 2010-2017 (P = 0.08). Overall survival in PsA did not differ from the general population (standardized mortality ratio 0.85 [95% CI 0.61-1.15]). CONCLUSION: The incidence of PsA in this predominantly White US population was stable in 2000-2017, in contrast to previous years. However, an increasing proportion of women with PsA was found in this study.","journal":"Arthritis & Rheumatology","year":2021,"id":157172,"datarank":2.0816350996741324,"base_score":3.9512437185814275,"endowment":3.9512437185814275,"self_citation_contribution":0.5926865577872142,"citation_network_contribution":1.4889485418869184,"self_endowment_contribution":0.5926865577872142,"citer_contribution":1.4889485418869184,"corpus_percentile":89.76560686934323,"corpus_rank":1324,"citation_count":51,"citer_count":46,"citers_with_citation_signal":36,"citers_with_endowment":36,"datacite_reuse_total":0,"is_dataset":true,"is_dataset_confidence":0.7988,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2021-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":275610,"name":"Cynthia S.
