N2 - Recently, there has been an influx of research interest regarding the anti-inflammatory role that diet has in chronic and metabolic diseases. A literature-based dietary inflammatory index (DII) that can be used to characterize the inflammation-modulating capacity of individuals' diets has even been developed and validated in an American population. We hypothesized that the DII could predict levels of high-sensitivity C-reactive protein (CRP), which is an important inflammatory marker, as well as metabolic measures that include the metabolic syndrome and its components in European adults. This hypothesis was tested according to data from 1352 participants from the Observation of Cardiovascular Risk Factors in Luxembourg study, a nationwide, cross-sectional survey based in Luxembourg. Statistical methods consisted of descriptive and multivariable logistic regression analyses. The DII ranged from a minimum of -4.02 (most anti-inflammatory) to a maximum of 4.00 points, with a mean value of -0.41. Participants with higher DII score were significantly younger and had lower body mass index, waist circumferences, and systolic blood pressure levels. Other cardiovascular biomarkers including diastolic blood pressure, CRP, lipids, and glycemic biomarkers did not vary significantly across DII tertiles. Participants with proinflammatory (>1) DII scores had increased adjusted odds (odds ratio, 1.46; 95% confidence interval, 1.00-2.13) of having a low high-density lipoprotein cholesterol, compared with those with anti-inflammatory scores (DII ≤1). There were no significant relationships between high-sensitivity CRP and the DII. This study, which tested the inflammatory capacity of the DII outside the United States, did not detect a significant independent relationship with cardiometabolic biomarkers, by using Food Frequency Questionnaire-collected data. These results are informative and representative of a relevant step in directing future research for nutrition and diet quality.
