This is the authors' abstract. We don't add key points for this paper.

BACKGROUND: Vitamin D deficiency is a common finding in chronic liver disease. It has also been linked to the pathogenesis of non-alcoholic fatty liver disease, hepatic fibrogenesis, decompensation and hepatocellular carcinoma. AIMS: We analyzed whether serum vitamin D is associated with incident advanced liver disease in the general population. METHODS: Serum 25-hydroxyvitamin D was measured in 13807 individuals participating in the Finnish population-based health examination surveys FINRISK 1997 and Health 2000. Data were linked with incident advanced liver disease (hospitalization, cancer or death related to liver disease). During a follow-up of 201444 person-years 148 severe liver events occurred. Analyses were performed using multivariable Cox regression analyses. RESULTS: < .001), when adjusted for age, sex, blood sampling season and stratified by cohort.The association remained robust and significant in multiple different adjustment models adjusting sequentially for 22 potential confounders. CONCLUSION: Low vitamin D level is linked to incident advanced liver disease at population level.
