Anti-inflammatory diets reduce the risk of excessive gestational weight gain in urban South Africans from the Soweto First 1000-Day Study (S1000)
No full textPURPOSE: To (i): examine whether maternal dietary inflammation assessed using the dietary inflammatory index (DII) is associated with gestational weight gain (GWG) and delivery outcomes in urban South African women from the Soweto First 1000-Day Study (S1000); and (ii): explore whether serum high-sensitivity c-reactive protein (hs-CRP) levels mediate these associations. METHODS: Energy-adjusted-DII (E-DII™) scores were calculated for 478 pregnant women using a quantitative food frequency questionnaire. GWG (kg/week) was assessed via anthropometry and hs-CRP concentrations were assessed in a sub-sample at < 14 (n = 263) and at 24–28 (n = 270) weeks gestational age. Multivariable linear and logistic regression models were used to examine associations between maternal E-DII scores, GWG, hs-CRP concentrations, and delivery outcomes. RESULTS: Positive vs. negative E-DII scores were associated with an increased odds of excessive weight gain (OR (95% CI): 2.23 (1.20; 4.14); P = 0.01) during pregnancy. Higher hs-CRP concentrations in the first trimester were associated with lower weight-for-length z-score (β (95% CI): −0.06 (−0.11; −0.01) per 1 mg/l hs-CRP; P = 0.02) and a reduction in odds of a large-for-gestational age delivery (OR (95% CI): 0.66 (0.47; 0.94); P = 0.02). Higher hs-CRP concentrations in the second trimester were associated with an increased odds of delivering preterm (OR (95% CI): 1.16 (1.01; 1.32); P = 0.03). CONCLUSIONS: Consumption of an anti-inflammatory diet during pregnancy reduced the risk of excessive GWG in a rapidly urbanising setting (Soweto, South Africa), where obesity prevalence rates are high. Further research is needed to better understand how maternal diet may ameliorate the effects of maternal adiposity on inflammatory milieu and fetal programming.

Secular trends in Dietary Inflammatory Index among adults in the United States, 1999–2014
No full textObjective: The objective of this study was to evaluate secular trends in Dietary Inflammatory Index (DII) scores in the United States between 1999 and 2014. Methods: Data from adults over 19 years from the 1999 to 2014 National Health and Nutrition Examination Survey (N = 39,191) were used. DII scores, at each 2-year cycle, were evaluated from a 24-h recall, including 26 food parameters for DII calculation. Analyses were conducted in 2018. Results: For the entire sample, there was a quadratic trend (Ptrend < 0.001), with the DII scores peaking in 2003–2004, and then decreasing during the cycles from 2005 to 2014. Similar quadratic trends (Ptrend < 0.001) were observed by age, gender, race-ethnicity, and education. Conclusion: Males, non-Hispanic Blacks, younger adults, and those with less education adults had the highest DII scores (i.e., indicating the greatest inflammatory potential). The overall DII scores of the US population showed a quadratic trend from 1999 to 2014. Continued monitoring of DII changes is needed to better understand changes in the inflammatory potential of diet of American adults, and how they relate to changes in the risk of chronic disease. © 2018, Springer Nature Limited
Dietary inflammatory index and acute myocardial infarction in a large Italian case-control study
No full textDiet and inflammation have been implicated to play a role in the incidence of acute myocardial infarction (AMI). In this Italian case-control study conducted between 1995 and 2003, we explored the association between the dietary inflammatory index (DII TM ) and AMI. Cases were 760 patients, below age 79 years, with a first episode of nonfatal AMI and controls were 682 patients admitted to hospital for acute conditions unrelated to diet. The DII was computed based on dietary intake assessed using a reproducible and validated 78-item food frequency questionnaire. Odds ratios (OR) were estimated through logistic regression models adjusting for age, sex, total energy intake, tobacco, body mass index, hypertension, hyperlipidemia and other recognized confounding factors. Higher DII scores (i.e., indicating a more pro-inflammatory diet) were associated with increased likelihood of AMI when expressed both as continuous (OR continuous =1.14, 95% confidence interval, CI:1.05, 1.24; one-unit increase in DII score corresponding to ≈9% of the range of DII) and as quartiles (OR Quartile4vs1 = 1.60, 95%, CI 1.06, 2.41; P -trend = 0.02). Stratified analyses produced slightly stronger associations between DII and AMI among women, ≥60 years, never smokers, subjects with history of hypertension and subjects with no family history of AMI, however, in the absence of heterogeneity across strata. A pro-inflammatory diet as indicated by higher DII scores is associated with increased likelihood of AMI
Association between dietary inflammatory index and prostate cancer among Italian men
No full textPrevious studies have shown that various dietary components may be implicated in the aetiology of prostate cancer, although the results remain equivocal. The possible relationship of inflammation derived from dietary exposures with prostate cancer risk has not been investigated. We examined the ability of a newly developed dietary inflammatory index (DII) to predict prostate cancer risk in a case-control study conducted in Italy between 1991 and 2002. A total of 1294 patients aged < 75 years with incident, histologically confirmed carcinoma of the prostate served as cases. A total of 1451 subjects aged < 75 years who were admitted to the same hospitals as cases for a wide spectrum of acute, non-neoplastic conditions served as controls. The DII was computed based on dietary intake assessed using a previously validated seventy-eight-item FFQ. Logistic regression models were used to estimate multivariable OR adjusted for age, study centre, years of education, social class, BMI, smoking status, family history of prostate cancer and total energy intake. Men with higher DII scores had a higher risk of prostate cancer when analysed using the DII as both continuous (OR 1·06, 95 % CI 1·00, 1·13) and categorical, i.e. compared with men in the lowest quartile of the DII, men in the third and fourth quartiles were at elevated risk (ORQuartile 3 v. 1 1·32, 95 % CI 1·03, 1·69 and ORQuartile 4 v. 1 1·33, 95 % CI 1·01, 1·76; P trend= 0·04). These data suggest that a pro-inflammatory diet, as indicated by the increasing DII score, is a risk factor of prostate cancer in Italian men
Association between the dietary inflammatory index and breast cancer in a large Italian case-control study
No full textIntroduction: The putative relationship between diet, including its inflammatory potential, and breast cancer has been studied extensively, but results remain inconsistent. Using data from a large Italian case-control study conducted between 1991 and 1994, we examined the association between the dietary inflammatory index (DII) and odds of breast cancer. Methods: DII scores were computed using a validated 78-item food frequency questionnaire. Subjects were 2569 women with incident, histologically confirmed breast cancer and 2588 controls admitted to hospital for acute, non-hormone-related diseases. Odds ratios (ORs) and 95% confidence intervals (CIs) based on continuous and quintiles of DII were estimated by multiple logistic regression adjusting for age, study center, education, BMI, parity, menopausal status, family history of hormone-related cancers, and total energy intake. Results: Women in quintiles 2, 3, 4 and 5 had ORs of breast cancer of 1.33 (95% CI: 1.11, 1.59), 1.37 (95% CI: 1.13, 1.66), 1.41 (95% CI: 1.15, 1.73), and 1.75 (95% CI: 1.39, 2.21), respectively, compared to women in quintile 1. One-unit increase in DII increased the odds of having breast cancer by 9% (95% CI: 1.05, 1.14). Conclusions: A pro-inflammatory diet is associated to increased risk of breast cancer
Association between Dietary Inflammatory Index and Gastric Cancer Risk in an Italian Case-Control Study
No full textBackground: In this study, we explored the association between the dietary inflammatory index (DII) and gastric cancer risk in an Italian case-control study. Materials and Methods: Cases were 230 patients with incident, histologically confirmed cases of gastric cancer from the Greater Milan area, Northern Italy. Controls were 547 frequency-matched subjects admitted to the same network of hospitals as cases for a wide spectrum of acute, non-neoplastic conditions. The DII was computed using a reproducible and valid 78-item food frequency questionnaire. Odds ratios (ORs) were estimated through logistic regression models conditioned on age and sex and adjusted for recognized confounding factors, including total energy intake. Results: Subjects with the most pro-inflammatory diet had a higher risk of gastric cancer compared to subjects with the most anti-inflammatory diet (ORQuartile4vs1 = 2.35, 95% confidence interval, 1.32, 4.20; P-trend = 0.004). Conclusion: These results indicate that a pro-inflammatory diet, as indicated by higher DII score, was associated with increased risk of gastric cancer
Dietary inflammatory index and risk of pancreatic cancer in an Italian case-control study
No full textPrevious studies have shown that various dietary components may be implicated in the aetiology of pancreatic cancer. However, the possible relationship between diet-related inflammation and the risk of pancreatic cancer has not yet been investigated. We examined the ability of a newly developed literature-derived dietary inflammatory index (DII) to predict the risk of pancreatic cancer in a case-control study conducted in Italy between 1991 and 2008. This included 326 incident cases and 652 controls admitted to the major teaching and general hospitals for non-neoplastic diseases, frequency-matched to cases by study centre, sex and age. The DII was computed based on dietary intake assessed using a validated and reproducible seventy-eight-item FFQ. Logistic regression models were used to estimate multivariable OR adjusted for age, sex, study centre, education, BMI, smoking status, alcohol drinking and history of diabetes. Energy adjustment was performed using the residual method. Subjects with higher DII scores (i.e. representing a more pro-inflammatory diet) had a higher risk of pancreatic cancer, with the DII being used as both a continuous variable (ORcontinuous 1·24, 95 % CI 1·11, 1·38) and a categorical variable (i.e. compared with the subjects in the lowest quintile of the DII, those in the second, third, fourth and fifth quintiles had, respectively, ORquintile2 v. 1 1·70, 95 % CI 1·02, 2·80; ORquintile3 v. 1 1·91, 95 % CI 1·16, 3·16; ORquintile4 v. 1 1·98, 95 % CI 1·20, 3·27; ORquintile5 v. 1 2·48, 95 % CI 1·50, 4·10; P trend= 0·0015). These data suggest that a pro-inflammatory diet increases the risk of pancreatic cancer
Dietary inflammatory index and ovarian cancer risk in a large Italian case–control study
No full textBackground: While inflammation has been shown to play an important etiologic role in ovarian carcinogenesis, little is known about the association between inflammatory properties of diet and ovarian cancer risk. Methods: We explored the association between the dietary inflammatory index (DII) and ovarian cancer risk in a multicentric Italian case–control study conducted between 1992 and 1999. Cases were 1,031 women with incident, histologically confirmed ovarian cancer from four areas in Italy. Controls were 2,411 women admitted to the same network of hospitals as the cases for acute, non-malignant and non-gynecological conditions, unrelated to hormonal or digestive-tract diseases or committed to long-term modifications of diet. DII scores were computed based on 31 nutrients and food items assessed using a reproducible and validated 78-item food frequency questionnaire. Odds ratios (ORs) were estimated through logistic regression models adjusting for age, total energy intake and other recognized confounding factors. Results: Subjects in the highest quartile of DII scores (i.e., with the most pro-inflammatory diets) had a higher risk of ovarian cancer compared to subjects in the lowest quartile (i.e., with an anti-inflammatory diet) (ORQuartile4vs1 1.47, 95% confidence interval, CI, 1.07, 2.01; ptrend = 0.009). When analyses were carried out using continuous DII, a significant positive association with ovarian cancer was observed: the OR for one-unit increment in DII score (corresponding to approximately 8 % of its range in the current study, +6.0 to −6.20) was 1.08 (95% CI 1.02, 1.14). Conclusion: A pro-inflammatory diet as indicated by higher DII scores is associated with increased ovarian cancer risk
Dietary inflammatory index and risk of esophageal squamous cell cancer in a case–control study from Italy
No full textPURPOSE:
Diet and inflammation have been suggested to be important risk factors for esophageal squamous cell cancer (ESCC). In this study, we examined the association between the dietary inflammatory index (DII) and ESCC in a case-control study conducted between 1992 and 1997 in Italy.
METHODS:
This study included 304 ESCC cases and 743 controls hospitalized for acute non-neoplastic diseases. The DII was computed based on dietary intake assessed by a reproducible and valid 78-item food frequency questionnaire. Logistic regression models were used to estimate odds ratios (ORs) conditioned on age, sex, year of interview, and area of residence and adjusted for education, smoking, alcohol drinking, BMI, physical activity, and aspirin use. Energy adjustment was performed using the residual method.
RESULTS:
Subjects with higher DII scores (i.e., with a more pro-inflammatory diet) had a higher risk of ESCC, with the DII being used as both a continuous variable (ORcontinuous 1.39, 95 % confidence interval, CI, 1.25-1.54; one-unit increase corresponding to ≈12 % of its range in the current study) and a categorical variable (ORquintile5vs1 2.46, 95 % CI 1.40-4.36; p trend < 0.001).
CONCLUSION:
These results indicate that a pro-inflammatory diet is associated with a higher risk of ESCC, even after controlling for alcohol and tobacco exposure
