This study estimated the incidence of juvenile-onset RRP before the implementation of the national HPV vaccination program in Korea.METHODS: We conducted a cohort study using claims data provided by a mandatory insurance program to estimate the incidence of RRP and associated healthcare use. Patients with juvenile RRP were defined as those aged \u226412 years with \u22652 admissions or \u22652 outpatient visits during which they received the International Classification of Diseases, 10th revision code for benign neoplasms of the larynx (D14.1).RESULTS: During 2002-2014, 123 children (74 boys and 49 girls) were diagnosed with RRP. The patients had a mean of 6.5 person-years of follow-up. The incidence was estimated at 0.30\/100,000 person-years. The median age at diagnosis was 4.0 years (mean, 4.3). Thirty-six (29.3%) patients underwent surgery, including 23 patients (18.7%) who underwent 2 or more surgical procedures. Severe disease, measured by more frequent surgical procedures and shorter time intervals between consecutive operations, was associated with a younger age at diagnosis.CONCLUSIONS: The estimated incidence of juvenile-onset RRP in Korea was similar to that reported in other countries. The RRP burden should continue to be monitored using National Health Insurance Service claims data.<\/jats:p>","DOI":"10.4178\/epih.e2021019","type":"journal-article","created":{"date-parts":[[2021,3,15]],"date-time":"2021-03-15T02:24:46Z","timestamp":1615775086000},"page":"e2021019","update-policy":"https:\/\/doi.org\/10.4178\/crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Estimated
