Little is known about the incidence of AAFD in the general population and specifically of AAFD requiring specialist care. We aimed to describe the incidence of AAFD referred to specialist care in the Swedish general population.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We conducted a nation\u2010wide epidemiological register study to estimate the incidence of referred AAFD in the general population. We retrieved data from the Swedish National Patient Register. All individuals aged 16\u00a0years or older, with a first\u2010time diagnosis of AAFD (ICD\u201010 code M214) between 2007 and 2018 were identified. Total incidences, change over time, and gender\u2010specific and age\u2010specific incidences per 100,000 person\u2010years were calculated using population size data from Statistics Sweden. Incidences were compared using the Poisson test.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The incidence rate of referred AAFD in the general population was 23.0 (95% CI 22.7\u201323.3) per 100,000 person\u2010years. The incidence rate in women was 30.4 (95% CI 29.9\u201330.8) and in men was 15.4 (95% CI 15.1\u201315.8). The highest incidence rates were found in the age Group 61\u201375\u00a0years. The incidence rates varied significantly across the 21 regions in Sweden. The age\u2010standardized and sex\u2010standardized incidence rates ranged from 8.3 (95% CI 7.2\u20139.4) to 69.1 (95% CI 62.4\u201375.8).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>AAFD requiring referral to specialist care is common in the general population.
