Plasma pepsinogens, nutrients, and diet in areas of Italy at varying gastric cancer risk.
1991
In a survey of 930 adults aged 35-74 years randomly sampled from the general population of four areas of Italy at different risks for gastric cancer (GC), plasma levels of pepsinogens (PGI and PGII) and fat-soluble vitamins were assayed. Pepsinogen levels were used to identify individuals with chronic atrophic gastritis (CAG). Severe CAG (PGI 20 pg/liter, but PGI/PGII < or = 2.9) was 6.3%. Moderate CAG was also related to age and social class and increased 1.8-fold in areas where GC rates were high, but was not strongly associated with diet or plasma nutrients. The authors discuss these findings in relation to those from a previous case-control study of GC in the same areas.
