Abstract

Objectives: The study aim was to identify changes in the nutritional status of older adults during the COVID-19 pandemic according to household income and demographic characteristics. Methods: Study participants were 2,408 adults aged 65 and over who participated in the 2019-2020 Korea National Health and Nutrition Examination Survey (KNHANES). To examine changes in nutrient intake levels resulting from COVID-19, data of 2019 and of 2020 were compared. Study participants were divided into three groups based on household income level to compare these changes. The changes were compared according to household income level, age group, and household type. Results: Percentages of recommended intakes for energy, protein, and most micronutrients were the lowest for the low-income group of both males and females in 2020. The Mean Adequacy Ratio (MAR) score was the lowest for the low-income group in both years. When comparing nutrient density for 2019 and 2020 by income group, the male low-income group experienced a decrease in nutrient densities of vitamin A, thiamine, calcium, and iron. For the same group, a decreased percentage for energy intake from protein was noted. Fruit intake was lowest in the low-income group for both males and females. Low-income males had the lowest intake levels for meat, fish, eggs, and legumes in both 2019 and 2020 and the lowest milk and milk product intake levels in 2020. Older adults living alone or single older adults with children had lower MAR scores than those living with a spouse. Older adults living alone experienced decreases in energy and thiamine and iron intake levels in 2020 compared to their intake levels in 2019. Conclusions: Because of the COVID-19 pandemic, nutrition intake levels worsened for older adult males in the low-income group and older adults living alone. This finding shows the need for a more systematic nutritional support strategy for the vulnerable older adults population in national disaster situations.
