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.

BACKGROUND/OBJECTIVES: Osteoporosis and osteoporosis-related disease are drawing a lot of attention in Korea as one of the serious health problems. Bone health status may be influenced by the general dietary quality and dietary pattern. SUBJECTS/METHODS: To determine the relationship between dietary quality and intake patterns and bone health status, the %RNI, NAR, DDS, and food group intake patterns were assessed according to their bone health status for 847 postmenopausal women using the 2010 KNHANES data after eliminating those of likely changing their diet under the advice of doctors or those taking estrogen. RESULTS: Bone health became worse as dietary quality deteriorated. All NAR and %RNI values were highly associated with bone health levels and the consumption frequency of Ca sources, DDS and the food group intake patterns also confirmed the findings. CONCLUSIONS: This study confirmed that dietary quality and dietary patterns were important for bone health. Nutritional education on eating foods from the five basic food groups has to be emphasized to prevent osteoporosis among older women.

The aim of this study was to compare the dietary patterns and behaviors of university students according to their type of residence. The subjects consisted of two thousand two hundred fifty students from Wonkwang University. They were divided into three groups : those who live in their family homes (393 men, 392 women) ; those who live in university dormitories (371 men, 401 women) : and those who live in houses with cooking facilities (345 men, 348 women). This cross-sectional survey was conducted using a self-administered questionnaire. The nutrient intake data collected from a three-day recall were analyzed using the Computer Aided Nutritional Analysis Program and the diet quality was estimated using the Nutrient Adequacy Ratio, Mean Adequacy Ratio and Index of Nutritional Quality. The results showed that the mean daily intakes of calcium were lower than the Korean Recommended Daily Allowance (RDA) in all groups. There was a significant difference in the nutrient intake, dietary quality and dietary behaviors of the three groups. The nutrients intake and dietary quality of the men were poorer than those of the women in all three groups. The subjects living in dormitories and houses with cooking facilities seemed to have lower levels of nutrient intake and dietary quality. However, the concern about nutrition and interest in health information was higher among those living in dormitories and houses with cooking facilities than among those living in their family homes. Male students living in houses with cooking facilities had more dietary problems than students living in their family homes or in dormitories possibly because they might have had a lower ability in meal management. These results suggest that the type of residence affects the nutrient intake levels, and dietary quality of university students in Iksan. Nutritional education is essential if university students are to practice optimal nutritional habits, including the eating of well-balanced diets and selecting of foods of high quality. Therefore, nutritional education for university students is needed so as to improve their health and a nutritional education program should be developed to meet the various needs of these students.

BACKGROUND/OBJECTIVES: As the prevalence of chronic diseases has risen, the need for straightforward diagnostic tools for monitoring nutrition status to improve nutrition counseling and disease prevention has likewise increased. This study developed an easily usable dietary behavior pattern diagnosis checklist and investigated its correlation with dietary quality index. SUBJECTS/METHODS: A draft dietary pattern evaluation tool was generated by analyzing previous studies. The draft questionnaire comprised 61 questions for assessing dietary habits. A survey was administered to 320 adults (19 to 64 years old) using the dietary pattern evaluation tool and 24-hour-recall method between March and May of 2014 in Jeonbuk province and the metropolitan area. Principal component analysis with varimax rotation was performed to identify dietary behavior patterns. Nutritional analysis was conducted using CAN-Pro 4.0, and the Diet Quality Index-International (DQI-I) was calculated to assess dietary quality. The correlation between dietary pattern scores and DQI-I scores was also analyzed. RESULTS: The factor analysis resulted in a total of 34 questions mapped to four main dietary behavior patterns: "high fat and calorie" pattern (12 questions), "overeating/binge" pattern (nine questions), "dietary impulse" pattern (eight questions), and "unbalanced food intake" pattern (five questions). The four dietary behavior patterns were negatively correlated with DQI-I adequacy and total scores (P < 0.01). CONCLUSIONS: The dietary pattern evaluation tool developed in this study can be used to diagnose a client's dietary behavior problems and is available as a nutrition counseling tool in the field.

The prevalence of atopic dermatitis (AD) continues to increase in the industrialized countries related to Western lifestyle and dietary patterns. The purpose of this study was to evaluate the nutritional status, dietary patterns and dietary quality of AD patients. AD patients (n=50) and gender age matched healthy control (HC) were studied in case-control clinical trail. Preference and frequencies of consumption for 98 foods were estimated by questionnaires. Dietary pattern, current nutrients intake, and dietary quality were evaluated by the 3-day food records. As a result, anthropometric measurements from HC and AD patients were not significantly different. AD patients had significantly lower preference for buckwheat, some fishes (shellfish, flatfish, salmon), egg yolk, some vegetables (onion, garlic, Chinese-cabbage, radish, pepper, mushroom), coffee, and snack than those of HC had (p<0.05). AD patients had significantly lower frequency for pea, some fishes (shellfish, herring, flatfish, salmon, codfish), egg, some vegetables (spinach, pumpkin, mushroom), margarine/butter, nuts, coffee and apple juice, fried chicken, coke than those of HC had (p<0.05). The intake of vitamin $B_1$, vitamin $B_2$ (p<0.05) and vitamin E (p<0.001) of AD patients were significantly lower than those of HC. The intake for Ca and Zn of AD patients were remarkably lower than RDA for each nutrient. Moreover, AD patients' index of nutritional quality (INQ) and nutrient adequacy ratio (NAR) of vitamin E, vitamin $B_1$, vitamin $B_2$ were lower than those of HC. AD patients' dietary quality including dietary diversity score (DDS), dietary variety score (DVS), DMGFV (dairy, meat, grain, fruit, vegetable), dietary quality index (DQI) was poor. This results indicate that atopic dermatitis patients had significantly different food preference and food frequency when these were compared with those of healthy people. The dietary diversity, dietary variety and dietary quality of atopic dermatitis patients were very limited.

The purpose of this study was to analyze the relationships among zinc status, diet quality, glycemic control and self-rated physical activity level of type 2 diabetic patients. Dietary intakes for two non-consecutive days were measured by 24-hour recall method for seventy-six diabetic patients. Fasting blood glucose and HbA1c were measured for the assessment of glycemic control. We evaluated the extent of dietary adequacy by the percentage of subjects with a dietary intake of a nutrient less than the estimated average requirement(EAR), the dietary diversity score(DDS) and the dietary variety score(DVS). Zinc status was assessed from serum levels and urinary excretion. Dietary inadequacy was serious for five nutrients: riboflavin, calcium, thiamin, zinc and vitamin C. Dietary intakes from the meat, fish, and egg food groups and the milk food group were below the recommended level. We found that subjects with high levels of physical activities had significantly higher DVS and serum zinc levels compared to others (p
