“…In a previous case-control study conducted in the same catchment area in which this study was based, we found that higher consumption of total fat, oleic acid, saturated fat, total PUFA, trans fat, MUFA, and linoleic acid were significantly associated with increased risk for UC; however, no statistically significant association was detected between the risk of UC and intake of n-3 PUFAs or cholesterol (23). Previously, the DII has been shown to be associated with reduced bone mineral density (24) and esophageal squamous cell cancer (25) in similar Iranian populations.…”

Background Diet and inflammation have been suggested to be important risk factors for ulcerative colitis (UC). Objectives In this case-control study conducted in Iran, we examined the ability of the dietary inflammatory index (DII) to predict UC. Methods This case-control study included 62 UC cases and 124 controls hospitalized for acute non-neoplastic diseases. The DII was computed based on dietary intake assessed by a previously validated food frequency questionnaire. Multivariable logistic regression models were used to estimate odds ratios (ORs) and the DII was analyzed as both continuous and as tertiles. Energy was adjusted using the residual method. Results Subjects with higher DII scores (i.e., with a more pro-inflammatory diet) had a higher risk of UC, with the DII being used as both a continuous variable (ORcontinuous 1.55, 95% confidence interval, CI, 1.04–2.32; one unit increase corresponding to ≈18% of its range in the current study) and as tertiles (ORtertile3vstertile1 2.58, 95%CI 1.03–6.48, Ptrend=0.04). Conclusions These results indicate that a pro-inflammatory diet is associated with increased risk of UC.

“…The DII also has been associated with a variety of cancers, including: colorectal and esophageal cancers [19–24] and, among urological cancers, with increased risk of prostate and bladder cancers [25–28]. In the Iowa Women’s Health Study (IWHS), the DII has been shown to be associated with colorectal and breast cancer incidence [29, 30] and mortality [31].…”

Background The association between inflammatory potential of diet and renal cancer risk has not been investigated. Methods In this study, we explored the association between the dietary inflammatory index (DII) and risk of renal cancer in the Iowa Women’s Health Study. From 1986 to 2011, 33,817 women initially recruited at 55–69 years of age were followed for incident renal cancers (n = 263). The DII was computed based on dietary intake assessed using a reproducible and valid 121-item food frequency questionnaire. Cox proportional hazards regression was used to estimate hazard ratios (HR) adjusting for age, body mass index, energy intake, smoking status, education, pack years of smoking, hypertension, and hormone replacement therapy. Results Multivariable analyses revealed positive association between higher DII scores and renal cancer risk (HR for DIIcontinuous: 1.07 per unit increase in DII (corresponding to 10% change in the DII range in the current study); 95% CI 1.00, 1.15; HR for DIItertile3vs1 = 1.52; 95% CI 1.09, 2.13). Stratified analyses produced slightly stronger associations between DII and renal cancer risk among women with BMI <30 kg/m2 (HRTertile3vs1 = 1.57; 95% CI = 1.04, 2.36) and ever smokers (HRtertile3vs1 = 2.35; 95% CI = 1.22, 4.55), although the corresponding interaction p values were not significant. Conclusion Pro-inflammatory diet, as indicated by higher DII scores, was associated with increased renal cancer risk.

“…High scores of this DII have been positively associated with a variety of cancers, including colorectal cancer (17, 18), and esophageal cancer (19–21) and, among urological cancers, prostate (22, 23), bladder cancers (24) renal cancer (25) and urothelial cancer (26). Using this case-control study conducted in Italy (27), this is the first attempt to examine the association between the DII and RCC risk.…”

Background: The relation between diet related inflammation and renal cell carcinoma (RCC) has not been investigated. Methods: In this study, we explored the association between the dietary inflammatory index (DII) and RCC in an Italian case-control study conducted between 1992 and 2004. Cases were 767 patients with incident, histologically confirmed RCC. Controls were 1534 subjects admitted to the same hospitals as cases for various acute, non-neoplastic conditions. The DII was computed based on dietary intake assessed using a reproducible and validated 78-item food frequency questionnaire. Odds ratios were estimated through logistic regression models conditioned on age, sex and center, and adjusted for recognised confounding factors, including total energy intake. Results: Subjects in the highest quartile of DII scores (i.e., with a more pro-inflammatory diet) had a higher risk of RCC compared to subjects in the lowest quartile (OR 1.41, 95% CI 1.02, 1.97; p-trend=0.04). Apparently stronger associations were observed among females (OR 1.68, 95% CI 0.93, 3.03), subjects aged <60years (OR 1.77, 95% CI 1.05, 2.98), BMI ≥25 kg/m2 (OR 1.64, 95% CI 1.07, 2.51), and ever smokers (OR 1.66, 95% CI 1.08, 2.57), in the absence of significant heterogeneity. Conclusion: A pro-inflammatory diet is associated with increased RCC risk.
