Omega-3 Fatty Acid Intake and Blood Lipids in Rural Older Adults: Analysis of the 2022 Korea National Health and Nutrition Examination Survey

Purpose: This study examines the relationship between omega-3 fatty acid intake and blood lipid levels among rural older adults in Korea. Methods: Using data from the 2022 Korea National Health and Nutrition Examination Survey, we conducted a cross-sectional analysis of 269 older adults aged 65 and above from rural areas. We analyzed variables such as omega-3 fatty acid intake, HDL cholesterol, LDL cholesterol, and triglycerides, adjusting for age, sex, BMI, and lifestyle factors. Results: Omega-3 fatty acid intake significantly reduces triglycerides and LDL cholesterol levelsbut does not affect HDL cholesterol. The low omega-3 intake observed among these rural older adults may contribute to poorer cardiovascular health, highlighting the need for dietary interventions. Conclusion: To enhance cardiovascular health in rural areas, customized nutritional interventions and public health policies are essential. Community programs promoting omega-3 intake can help bridge the health gap between rural and urban older adults and support healthy aging in rural populations.
