A national cross-sectional study on breakfast skipping-related factors and comparison of nutritional status according to breakfast skipping in older adults based on the 8th Korea National Health and Nutrition Examination Survey (KNHANES, 2020).

There were distinct socioecological features and nutritional conditions of older adults relying on breakfast skipping; and a strong association between breakfast skipping, socioecological parameters, and nutrient intake quality. These observations provide the significance of breakfast skipping in the nutritional status of older adults and offer fundamental information for nutritional education and implications for older adults.
