Time trends in pediatric fractures in a Swedish city from 1950 to 2016. Acta Orthop. 2020 Jun 26;:1-10 Authors: Bergman E, Lempesis V, Nilsson JÅ, Jephsson L, Rosengren BE, Karlsson MK Abstract Background and purpose - As previous studies indicate time trends in pediatric fracture incidence, we followed the incidence in a Swedish city between 1950 and 2016.Patients and methods - Malmö city, Sweden had 322,574 inhabitants in 2015. We used diagnosis registry, charts, and radiographs of the only city hospital to classify fractures in individuals < 16 years in 2014-2016, and compared these with data from 1950-2006. We used joinpoint regression to analyze time trends and present results as mean annual percentage changes (APC). Differences between periods are described as incident rate ratios (IRR). To describe uncertainty, 95% confidence intervals (CI) are used.Results - During 2014-2016 the pediatric fracture incidence was 1,786 per 105 person-years (boys 2,135 and girls 1,423). From 1950 onwards age-adjusted fracture incidence increased until 1979 in both boys (APC +1.5%, CI 1.2-1.8) and girls (APC +1.6%, CI 0.8-2.5). The incidence remained stable from 1979 to 2016 (APC in boys 0.0%, CI -0.3 to 0.3 and in girls -0.2%, CI -1.1 to 0.7). Age-adjusted incidence 2014-2016 was higher than 2005-2006 in girls (IRR 1.1, CI 1.03-1.3), but not in boys (IRR 1.0, CI 0.9-1.1).Interpretation - Fracture incidence was in girls higher in 2014-2016 t...
