In the present study, the association of dietary patterns with gastric cancer risk was studied.<br> Methods: In the present case-control study, 192 newly diagnosed gastric cancer patients and 365 subjects as control group were included. The participants in each group underwent face-to-face interview. For food pattern determination, a 100-item qualitative food frequency questionnaire (FFQ) and exploratory factor analysis method were used. Logistic regression was used for determination of association between derived dietary patterns and gastric cancer risk.<br> Results: Four major dietary patterns with 55.48% prediction rate, namely &ldquo;tubers and spices&rdquo;, &ldquo;cereals and dairies&rdquo;, &ldquo;healthy&rdquo; and &ldquo;Western-style&rdquo;, were identified. Tubers and spices [in males: 11.42 (4.17, 26.75); in females: 6.94 (2.24, 21.56)] and &ldquo;Western-style&rdquo; dietary patterns [ in males: 1.16 (1.00-4.35); in females: 2.25 (1.10, 6.49] significantly increased the odds of gastric cancer risk in both sex. However, &ldquo;healthy&rdquo; dietary pattern and &ldquo;cereals and dairies&rdquo; dietary pattern were not associated with gastric cancer risk (P>0.05).&nbsp;<br> Conclusion: In Iranian population, consumption of diets high in tubers, spices and salts (labelled tubers and spices), processed meat, high energy drinks, snacks and desserts (labelled western-style) tended to increase the risk of gastric cancer. More longitudinal studies with large sample size and accurate estimate of dietary intake is suggested until more precise conclusion could be achieved.</span></span></span></p> Gastric cancer, Dietary pattern, Factor analysis, Case-control study, Iran 12 17 http://ijbc.ir/browse.php?a_code=A-10-714-1&slc_lang=en&sid=1 Zeinab Nikniaz znikniaz@hotmail.com 10031947532846008990 10031947532846008990 Yes Liver and gastrointestinal diseases research center, Tabriz University of medical sciences, Tabriz Iran Mohammad Hossein Somi mhosseinsina@yahoo.com 10031947532846008991 10031947532846008991 No Liver and gastrointestinal diseases research center, Tabriz University of medical sciences, Tabriz Iran Mohammad Asghati Jafarabadi M.asghari862@gmail.com 10031947532846008992 10031947532846008992 No Road Traffic Injury Research Center, Tabriz University of Medical Sciences, Tabriz, Iran Shahnaz Naghashi Shahnaz.naghashi@gmail.com 10031947532846008993 10031947532846008993 No Liver and gastrointestinal diseases research center, Tabriz University of medical sciences, Tabriz Iran Elnaz Faramarzi Elnaz.faramarzi849@gmail.com 10031947532846008994 10031947532846008994 No Liver and gastrointestinal diseases research center, Tabriz University of medical sciences, Tabriz Iran
