We reported a mass screening in 1990 of X town in Japan which demonstrated a high prevalence of hepatitis C virus HCV infection. This follow-up study determined through a period of 12 years whether serum albumin levels impact on the life prognosis of the residents of X town. Results Of the 509 subjects 69 had died and 55 had moved to other regions by 2002. Therefore we analyzed 454 people for whom we could confirm life and death between 1990 and 2002. Albumin levels were assigned to two groups low g L group A and normal g L group B . Of the 454 subjects analyzed 25 were in group A and 429 in group B and the mortality was 17 25 cases P vs. group B and 52 429 respectively. Mortality from hepatocellular carcinoma HCC was in group A 6 9 cases P vs. group B and 3 19 in group B. According to multivariate analysis five factors - 50 years or older low albumin level g L abnormal AST level history of smoking and absence of alcohol consumption - were associated with death. The adjusted odds ratios for these five factors were and respectively and each was statistically significant. Conclusions We show that the serum albumin level is an independent risk factor for mortality from all causes in the residents of X town and an important prognostic indicator. Improvement of hypoalbuminaemia should be considered for improvement of prognosis. Background Hypoalbuminemia can be caused by various conditions including nephrotic syndrome 1 2 heart failure 3 liver disease 4 5 and malnutrition 6 . Most cases of hypoalbuminemia among hospitalized patients are caused by acute and chronic inflammatory
