We aimed to quantify the association between dietary patterns and gastric cancer, by location and histological type, according to <jats:italic>Helicobacter pylori<\/jats:italic> infection status. We analyzed 591 incident cases of gastric adenocarcinoma and 1,463 community controls. Dietary intake was assessed using a validated food frequency questionnaire. Principal components and cluster analyses were used to define dietary patterns. Anti\u2010<jats:italic>H. pylori<\/jats:italic> IgG was assessed by ELISA. Age\u2010, gender\u2010, education\u2010 and total energy intake\u2010adjusted odds ratios (OR) were computed. Three dietary patterns were identified, with the following main characteristics: (I) high consumption of fruits and dairy products, and low consumption of alcoholic beverages; (II) low consumption of fruit, salads, vegetables, dairy products, fish and meat; (III) high consumptions of most food groups and low vegetable soup intake. Compared to pattern I, the risk of gastric cancer was higher for pattern II (OR = 1.68, 95% CI: 1.31\u20132.14) but not for pattern III (OR = 0.80, 95% CI: 0.57\u20131.14), with no effect modification by <jats:italic>H. pylori<\/jats:italic> infection. The association was similar for cardia and non\u2010cardia gastric cancer, but for tumors of the diffuse Laur\u00e9n histological type, the association was weaker for pattern II <jats:italic>vs<\/jats:italic>. I (OR = 1.32, 95% CI: 0.83\u20132.08) and a protective effect was observed for pattern III <jats:italic>vs<\/jats:italic>. I (OR = 0.43, 95% CI: 0.22\u20130.87). Our results confirm the protective effect of high fruit and vegetables intake, and show a differential association according to histological type. No effect modification by <jats:italic>H. pylori<\/jats:italic> infection was observed.<\/jats:p>","DOI":"10.1002\/ijc.25013","type":"journal-article","created":{"date-parts":[[2009,10,29]],"date-time":"2009-10-29T20:38:59Z","timestamp":1256848739000},"page":"433-441","source":"Crossref","is-referenced-by-count":24,"title":["Dietary patterns and gastric cancer in a Portuguese urban population"],"prefix":"10.1002","volume":"127","author":[{"given":"Joana","family":"Bastos","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nuno","family":"Lunet","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"B\u00e1rbara","family":"Peleteiro","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carla","family":"Lopes","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Henrique","family":"Barros","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2010,1,21]]},"reference":[{"key":"e_1_2_5_2_2","volume-title":"World Health Organization Mortality Database [Internet]"},{"key":"e_1_2_5_3_2","doi-asserted-by":"publisher","DOI":"10.1038\/sj.onc.1207726"},{"key":"e_1_2_5_4_2","doi-asserted-by":"publisher","DOI":"10.1093\/oxfordjournals.epirev.a036288"},{"key":"e_1_2_5_5_2","doi-asserted-by":"publisher","DOI":"10.1207\/s15327914nc5301_1"},{"key":"e_1_2_5_6_2","unstructured":"Food Nutrition Physical Activity and the Prevention of Cancer: a Global Perspective [Internet].
