| Abstract: | Background and objective: The second most common cancer in men after lung cancer is prostate cancer (PC).Previous studies assessed the association between food items or food groups and the risk of PC, but diet quality indicesare unique approaches to study any relations between diet and disease. Our objective was to investigate the effect ofhealthy eating index (HEI-2010) and Mediterranean-Style Dietary Pattern Score (MSDPS) on PC risk. Methods: Inthis case-control study, we recruited 97 patients with MS and 205 control subjects . Dietary intake was evaluted usinga valid and reliable food frequency questionnaire. The HEI and MSDPS were calculated. Logistic regression was usedto evaluate the relationship between HEI and MSDP scores and PC risk after adjusting the confounders. Results: Incomparison to controls, cases had lower score on HEI (61 vs. 70.07; P< 0.001), and higher score on MSDP (26.20 vs.24.49; P= 0.44). After comparing the highest and the lowest tertile of HEI, we observed a significant decreasing trendin the risk of PC (p for trend<0.001). Conclusion: Our findings suggested that a high quality diet, according to HEI,may decrease the risk of PC. |
