A population-based case-control study of gastric cancer was conducted in areas with contrasting incidence rates in Sweden.
Face-to-face interviews were carried out with 338 (74.1%) of all eligible cases and 679 (77.3%) of the selected controls.
Consumption of selected nutrients during adolescence and 20 years prior to interview was estimated, together with life-time intake of vitamin supplements.
Ascorbic acid and bêta-carotene had an unequivocal protective effect, but alpha-tocopherol and nitrate were also negatively associated with gastric-cancer risk.
In a multivariate analysis including all of these factors, only ascorbic acid remained a significant protective factor.
