Abstract

The association between HCV infection, measured as positivity to anti-HCV antibodies, an. The incidence of DM 2 in a cohort of subjects sampled fro. The general population and followed up for 20 years.METHODS:At baseline. The cohort consisted of a random sample of 2,472 subjects (72% response rate, age range 30-69 years) fro. The electoral register of a town in Southern Italy. The cohort subjects were examined three times: in 1985 (M1), in 1992 (M2), and in 2005 (M3). At M1, M2, and M3, each participant filled in a questionnaire and had a blood sample taken to measure blood glucose and other serum variables including glutamic pyruvic alanine aminotransferase (ALT). Anti-HCV antibodies were analyzed with standard techniques at M1 and M2.
