Summary Objectives: To evaluate relationships between self-reported physical activity, proportions of long-chain omega-3polyunsaturated fatty acids (LCn3) in erythrocyte content (percentage of total fatty acids) and risk of mild cognitiveimpairment (MCI) in older adults.Method: A cross-sectional study was conducted. Community-dwelling male and female (n D 84) participants over the ageof 65 years with and without MCI were tested for erythrocyte proportions of the LCn3s eicosapentaenoic acid (EPA) anddocosahexaenoic acid (DHA). Physical activity was measured using a validated questionnaire.Results: The interaction between erythrocyte EPA, but not DHA, and increased physical activity was associated withincreased odds of a non-MCI classification.Conclusion: An interaction between physical activity and erythrocyte EPA content (percentage of fatty acids) significantlypredicted MCI status in older adults. Randomised control trials are needed to examine the potential for supplementationwith EPA in combination with increased physical activity to mitigate the risk of MCI in ageing adults.
