Objectives: To investigate temporal trends in the incidence and prevalence of gout in the adult Danish population. Methods: Using the nationwide Danish National Patient Registry, we calculated the number of incident gout patients (per 100 000 person-years) within each 1 year period from 1995 to 2015 and the prevalence of gout in 2000 and 2015. Further, we calculated age- and gender-specific incidence rates of gout from 1995 to 2015. Results: We identified a total of 45 685 incident gout patients (72.9% males) with a mean age of 65 years (s.d. 16) at diagnosis. In both genders, an increase in age-standardized incidence rates was observed from 32.3/100 000 (95% CI 30.7, 33.9) in 1995 to 57.5/100 000 (95% CI 55.6, 59.5) in 2015 (P < 0.001). Similar trends were observed for 8950 cases diagnosed in rheumatology departments. We likewise observed an increase in the prevalence of gout from 0.29% (95% CI 0.29, 0.30) in 2000 to 0.68% (95% CI 0.68, 0.69) in 2015. Conclusions: The annual incidence rate of gout increased by almost 80% in Denmark between 1995 and 2015. The prevalence increased by nearly 130% between 2000 and 2015. Reasons for this are unknown but may include an increase in risk factors (e.g. obesity, diabetes mellitus), longer life expectancy and increased awareness of the disease among patients and/or health professionals.
