Abstract

Background Although adherence to "Dietary Approaches to Stop Hypertension" (DASH) dietary pattern has been linked with reduced risk of several cancers. To our knowledge no studies have examined the association between the DASH dietary pattern and risk of gastric cancer. This study was performed to investigate the association between adherence to the DASH dietary pattern and odds of gastric cancer in Iran. Methods This hospital-based case-control study was conducted on 178 histo-pathologically confirmed patients with gastric cancer and 276 sex-matched healthy controls. A validated 146-item Diet History Questionnaire (DHQ) was used to assess participants' usual dietary intakes. The DASH dietary pattern scores were calculated using the method introduced by Fung. Unconditional logistic regression, in which potential confounders were taken into account, was applied to determine the association of adherence to the DASH dietary pattern and odds of gastric cancer. Results Mean age of cases and controls were 60.8 and 53.2 y, respectively. After controlling for age, sex and energy intakes, participants in the highest tertile were 62 less likely to have gastric cancer than those in the lowest tertile (OR 0.38; 95 CI 0.22,0.65; P-trend < 0.004). Further adjustment for other potential confounders, including education, marital status, residential place, alcohol intake and smoking, did not change the association dramatically (OR 0.44; 95 CI 0.25, 0.78; P-trend = 0.005). Even after additional controlling for H-Pylori infection and BMI, greatest adherence to the DASH dietary pattern was associated with a 54 decreased risk of gastric cancer (OR 0.46; 95 CI 0.26, 0.83; P-trend = 0.01). Conclusions Adherence to the DASH dietary pattern was associated with lower gastric cancer risk in this case-control study.
