Abstract
Omega-3 polyunsaturated fatty acids (n-3 PUFAs) have unique properties that benefit female athletes. No study has examined the association between the dietary inflammatory index (DII) and omega-3 index. Therefore, we investigated the association between the DII and omega-3 index. This cross-sectional study included female university athletes and age- and sex-matched controls. Data were collected from anthropometric assessments, a food frequency questionnaire (FFQ), and blood tests for lipidomics. The energy-adjusted DII was calculated using the FFQ. Seventy-four athletes (mean age=19.7±1.2 y, mean BMI=21.1±2.4) and 38 controls (mean age=20.0±0.9 y, mean BMI=20.3±2.4) were enrolled in the study. The athlete group tended to have a higher percentage of high risk/intermediate in the omega-3 index (75.7% vs. 57.9%; p=0.082) or high-risk category in the trans-fat index (9.5% vs. 0.0%; p=0.093) compared to the control group. The energy-adjusted DII negatively correlated with the omega-3 index, although n-3 PUFA intake did not correlate with the omega-3 index in either group. The present findings indicated that DII might affect omega-3 index independent of n-3 PUFAs intake in female athlete. Health care professionals and coach should consider nutritional interventions based on the omega-3 index rather than relying solely on n-3 PUFAs intake for female athletes.

The Journal of Nutritional Science and Vitaminology is an international medium publishing in English of original work in all branches of nutritional science, food science and vitaminology from any country.
Manuscripts submitted for publication should be as concise as possible and must be based on the results of original research or of original interpretation of existing knowledge not previously published. Although data may have been reported, in part, in preliminary or
abstract form, a full report of such research is unacceptable if it has been or will be submitted for consideration by another journal.
