Employed workers 18{\textendash}65 resident in Sweden in 2013 were included in the study (n=82 949 OIs). Precarious employment was operationalised using the national labour market register, while injury severity was constructed from the National Patient Register. Under-reporting estimates were computed stratifying by OIs severity and by sociodemographic characteristics, occupations and precarious employment.Results Under-reporting of OIs followed a dose{\textendash}response pattern according to the levels of precariousness (the higher the precarious level, the higher the under-reporting) being for the precarious group (22.6\%, 95\% CI 21.3\% to 23.8\%), followed by the borderline precarious (17.6\%, 95\% CI 17.1\% to 18.2\%) and lastly the non-precarious (15.0\%, 95\% CI 14.7\% to 15.3\%). Under-reporting of OIs, decreased as the injury severity increased and was higher with highest level of precariousness in all groups of severity. We also observed higher under-reporting estimates among all occupations in the precarious and borderline precarious groups as compared with the non-precarious ones.Conclusions This is the first register-based study to empirically demonstrate in Sweden that under-reporting of OIs is 50\% higher among precariously employed workers. OIs under-reporting may represent unrecognised injuries that especially burden precariously employed workers as financial, health and social consequences shift from the employer to the employee.Data can be obtained through acquisition from Swedish registers.
