Selected micronutrient intake and the risk of gastric cancer. (original) (raw)

1994, … Biomarkers & Prevention

The relationship between intake of seleded micronutrients and gastric cancer risk was investigated using data from a case-control study conduded in Italy between 1 985 and 1 992 on 723 cases of histologically confirmed, incident gastric cancer, and 2024 controls hospitalized for acute, nonneoplastic, nondigestive trad diseases. Relative risks of subsequent quintiles of intake were computed after allowance for sex, age, and other major identified potential confounding fadors, including an estimate of total calorie intake. No trend in risk emerged for intake of retinol, vitamin D and vitamin E, whereas a protedive pattern was observed for consumption of beta-carotene, ascorbic acid, folate, and nitrates, with risk estimates for the highest intake quintiles of 0.27, 0.40, 0.58, and 0.43, respedively. Significant dired trends in risk were found for methionine, calcium, and nitrites. When the effed of various micronutrients was taken into account, a residual protedive effed was observed for beta-carotene
