Purpose: This study examined the food and nutrient intake of Korean elderly according to the anxiety and depressive condition using the data from the Korea National Health and Nutrition Survey (KNHANES) from 2013 to 2015. Methods: The participants were 3,504 elderly people over 65 years of age (1,523 in men and, 1,981 in women). The dietary information was analyzed using the 24-hour recall data. The anxiety and depressive state was assessed using the self-reported scale EQ-5D in the quality of life dimension. The subjects were divided into the anxiety depression group (AD) and non-anxiety depression group (NAD) according to their anxiety and depressive conditions. Results: In the male elderly, the AD group had a significantly lower education and economic level and higher proportion in living alone than the NAD group. The percentage of eating lunch and dinner alone in the male AD group was higher than that of the NAD group. The female AD group showed less a lower frequency of dinner than the NAD group. The male AD group had a lower consumption of total foods, fish and shellfishes, seaweeds, mushrooms, oils and fats, and seasonings than the NAD group. With regard to the nutrient intake, the male elderly NAD group had more sufficient nutrient intakes than the AD group. In particular, the daily intakes of dietary fiber, riboflavin, niacin, potassium and iron were significantly lower in the AD group. To compare with the nutrient density of the two groups, the vitamin C and niacin intakes were lower in the AD group than in the NAD group. Overall, the nutritional status of the male AD group was significantly lower than that of the NAD group. Meanwhile, the female elderly had showed a smaller difference in nutrient intake according to their anxiety and depressive condition. Conclusion: These results of this study show that more nutritional education and emotional support are needed to improve the nutritional status and health of the male elderly with anxiety or depression. 본 연구는 국민건강영양조사 제 6기 (2013 ~ 2015년) 자료를 이용하여 우리나라 65세 이상 노인의 주관적 불안 우울 상태에 따른 식품 및 영양소 섭취 실태를 분석한 것으로 그 결과는 다음과 같다. 남자 노인의 불안 우울군이 비불안 우울군에 비하여 저체중군 비율이 높고 과체중군의 비율이 낮았다. 불안 우울군의 교육 수준과 경제 수준이 더 낮았으며 독거가구의 비율은 더 높아서 혼자 사는 노인이 더 많은 것으로 나타났다. 남녀 노인 모두 불안 우울군의 주관적 건강상태가 더 나쁜 것으로 나타나 스스로 건강하지 않다고 생각하는 비율이 높았다. 남자 노인의 불안 우울군이 점심식사와 저녁 식사 시 혼자 식사하는 비율이 높았고 여자 노인의 경우, 불안 우울군의 저녁식사 빈도가 낮은 것으로 나타났다. 남자 노인의 불안 우울군에서 총 식품섭취량, 버섯류, 어패류, 해조류, 유지류, 조미료류의 섭취가 비불안 우울군에 비하여 낮았다. 반면 여자 노인의 경우 총 식품섭취량과 그 외의 모든 식품군
