Original Contribution Dietary Patterns and Risk of Incident Gastric Adenocarcinoma

Few studies have assessed the relation between dietary patterns and gastric adenocarcinoma risk, yet this approach has advantages over single-nutrient analysis, including the ability to reflect eating patterns in populations and ease of implementing dietary recommendations. The authors evaluated associations between dietary pat-terns, a food index score, and incident gastric cancer risk in a Canadian study of 1,169 cases and 2,332 controls (1995–1997). Dietary patterns were assessed via factor analysis applied to a food frequency questionnaire. A food index score was derived based on risk factors for gastric cancer. A multivariable-adjusted prudent dietary pattern was associated with decreased risk of gastric cancer in women (odds ratio (OR) 0.58, 95 % confidence interval (CI): 0.37, 0.92); a Western dietary pattern was associated with increased risk in women (OR 1.86, 95 % CI: 1.20, 2.89) and men (OR 1.44, 95 % CI: 1.03, 2.02). The food index score was associated with decreased risk amon
