Objective To determine whether occupational exposure to silica dust is associated with an increased risk of developing sarcoidosis. Design Case–control study of all individuals between 20 and 65 years of age diagnosed with sarcoidosis (D86) in Sweden between 2007 and 2016. Controls were matched to cases (2:1) based on age, sex and county at the time of diagnosis. A Job Exposure Matrix was used to estimate the occupational silica exposure of all cases and controls. Setting Medical and occupational data from the National Outpatient Register were used to implement a case–control analysis, while the two controls used for each case were selected from the National Register of the Total Population. Information about occupation and time of employment were collected from the Swedish Occupational Register. Participants All men and women aged 20–65 years old who were diagnosed sarcoidosis (D86) from 2007 to 2016 were included and assigned two controls. Main outcomes Silica dust exposure correlates with an increased risk of developing sarcoidosis in men. Results The prevalence of silica exposure at work was statistically significantly higher among male cases than controls (OR 1.27, 95% CI 1.13 to 1.43). For men of an age of 35 years or younger the correlation seems to...
