This study assessed yearly trends of food and nutrient intake among high school students aged 16 to 18 years (n=2,377) using the 2007~2015 Korea National Health and Nutrition Examination Survey (KNHANES). Yearly trends of food or nutrient intake were analyzed via logistic regression analysis. The results showed that consumption of sugars & sweets, and beverages & alcohols was increased rapidly during this period (p<0.0001). Intake of meat & meat products, and fish & shellfish also was increased (p=0.0008). Intake of grains and grain products was increased until year 2011 but declined after 2012 (p=0.0025). Consumption of vegetables, and milk & milk products was decreased (p=0.0395). Intake of protein, fat, thiamin, riboflavin, niacin, and iron was increased (p=0.0445). Carbohydrate energy ratio was decreased, whereas fat energy ratio was increased (p=0.0235). Most nutrient intakes satisfied the dietary reference intakes for Koreans except dietary fiber (19.6~26.2%), calcium (46.9~55.2%) and sodium (more than 221.4%) during this period. There was a significant positive correlation between most food group intakes and most nutrient intakes (p=0.0468). Therefore, it is crucial to increase dietary fiber and calcium intake and decrease consumption of sugars, fats and sodium through diverse eating of food groups to ensure balanced nutrition of subjects.

A Survey was carried out to investigate relation between depressive trends, stress and attitudes of food intake in adults. In the assessing of Body Mass Index (BMI), the normal weight was 80.1%, overweight was 19.1%, obese was 0.7% in men, but normal weight was 90.3%, overweight was 9.4%, obese was 0.3% in women (p<0.001). It was represented increasing trends of obesity by the increasing of ages. Women thought their health condition was worse than men (p<0.001) 15.1% of all women tried to weight control. In changes of food intake by stress, 37.8% was increased to eat, 33.7% was reduced in women. It seems that women was significantly influenced by stress than men (p<0.01). In changes of food intake by stress in ages, 39.7% was increased of 20 years but over the 30 years was decreased or no changes of food intake (p<0.0001). All subjects wanted hot and sweet taste when stress-induced eating. 56.1% of men preferred to alcohol and beverages but 33.5% of women preferred to chocolate, cookies and breads of carbohydrate foods at the stressful conditions. But stress-induced eating dose not seems to be helpful for coping with stress in adults. In the distribution of depressive trends, the level of depression was higher in women (50.7%), whereas 34.3% in men (p<0.001). The most of 3li subjects represented attitudes of food intake below 60 scores that was needed improve and counseling of professional nutritionist. It was represented inferior to attitudes of food intake by the increasing of depressive trends and stress in women. It was higher level of overweight and obese in the below 60 scores of attitudes of food intake and higher depressive groups.
