Purpose: This study was performed to identify the health and nutritional status of Korean adults according to food security by age group. Methods: The subjects were 20~79 year old adults (n = 16,595) who participated in the fifth Korea National Health and Nutrition Examination Survey (2010~2012). Subjects were divided into three groups based on food security such as secure, mildly insecure, and moderately/severely insecure groups. Dietary intake was estimated by 24-hour dietary recall. As for mental health status, the data on mental stress, sleep hours, depression symptoms, and suicide ideation were used. Results: Korean adults who were exposed to high food insecurity typically had low income levels, lived alone, and were recipients of basic welfare. In the 20~39y group, people with higher food insecurity had lower concentrations of hemoglobin and higher iron-binding capacity. In the 40~59y group, people with higher food insecurity had lower HDL-cholesterol. In the 60~79y group, people with higher food insecurity had higher total cholesterol levels, more stress, more experiences of depression symptoms, and were more suicidal. Mean intakes of energy, protein, calcium, phosphorus, potassium, vitamin A, carotene, vitamin $B_1$, vitamin $B_2$, niacin, and vitamin C were lower in the food insecure groups. Amounts of vegetables, fruits, and seasoning intakes tended to be lower in people with higher food insecurity. The effects of food security on nutrition intake were greater in the 40~59y and 60~79y groups than the 20-39y group. Conclusion: Food insecurity was related to certain health indicators such as anemia and cholesterol levels and affected mental health. The effects of food insecurity on health and nutritional status were different by age group.
