Abstract

The purpose of this study was to compare the differences in the quality of dietary and life across age groups of Korean adults. According to life cycle, four age groups (20~29, 30~49, 50~64, ≥65) were created. Anthropometric indices showed significant differences according to age group (p<0.001). Energy intake significantly decreased according to age group as a result of decreased protein and fat intake (p<0.001). The intake levels of minerals, vitamins, and dietary fiber per 1,000 kcal were the lowest in the 20~29 age group (p<0.001). Whereas saturated fatty acids, MUFA, and PUFA intake levels were the highest for those in the 20~29 age group (p<0.001). The quality of dietary (DQI-I) increased with age group, but the quality of life (EQ-5D index) decreased (p<0.001). The quality of dietary showed 5.8% explanation power on the quality of life (p<0.001). Additionally, diet moderation was shown as having a negative effect, but the diversity and balance of diets had a positive effect on the quality of life. By age group, the relationship between quality of dietary and quality of life was the highest in ≥65 age group. These results suggest that practical dietary education is needed from the 20's to ensure the quality of healthy life for the elderly.
