This study was performed to assess the effect of eating behaviors and health-related variables on overall dietary quality. Ninety-four(male 21, female 73) elderly who were over 60 residing in middle income areas in Cheongju city participated. Information on general characteristics of the elderly, health-related life style, regularity of meal, meal balance and desirable eating habits were obtained by interview based on questionnare. Dietary nutrient intake data were obtained through the 24 hour recall method. The mean age and BMI of the subjects were 73.3 years old and 23.3(male 21.8 female 23.7) respectively. The proportions of underweight and hypertension were 19.2% and 36.2%. Most nutrients except vitamin $B_2$ and calcium were consumed over 75% of the RDA. The Mean Adequacy of Ratio(MAR) of nutrient intake was 0.64(male 0.72, female 0.62). The average score of regularity of meal, meal balance, and desirable eating habits was 14.4 out of a possible 16, 13.7 out of a possible 24 and 5.5 out of a possible 16 points respectively. Male than female, older subjects than young subjects, and those living with their spouses than with other family or living alone had better scores in eating behaviors. Smoking, chewing ability and eating alone vs eating with company affected overall of regulality of meal and meal balance(p<0.05). Positive correlation (p<0.05) was also dietary quality. There was a positive correlation between the mean adequacy ratio, score observed between scores in regularity of meal and meal balance. Therefore, the elderly should be encouraged to eat a variety of food, maintain good dental health, keep regularity of meal and have meals with company to help improve overall dietary quality and eventually achieve optimal nutritional status.

To provide the baseline information for establishing community based nutritional service system in the context of health promotion, we conducted nutrition survey for 196 adults (male ; 99, female ; 97) in Kyungpook area. Individual food intake was measured by 24-hour recall method, and then diet quality was evaluated by Index of Nutritional Quality (INQ) and Mean Adequacy Ratio (MAR). Average dietary intake of Ca and Vit A of total subjects were lower than Korean Recommended Dietary Allowances (Ca; 83% of RDA, Vit A; 77% of RDA). On the whole, mean nutrients intake of male subjects were higher than that of female subjects. It also appeared that overall nutrients intake of younger women (20~29 yr) were lower than that of other age group. When we evaluated the nutrients intake of the subjects by INQ, Vit C (=2.39) showed the highest score. Ca (=0.89) and Vit A (=0.84) were revealed to be concerned nutrients in both quantity and quality. There was almost no difference in MAR between men and women (Men ; 0.88, Women ; 0.86). MAR showed significantrly positive correlation with age (p<0.05), meal frequency (p<0.001) and negative correlation with education level (p<0.01) in women, whereas no statistically significant relationship among these variables was observed in men. Age and meal frequency showed significantly positive correlation with most nutrients intakes among women. In conclusion, nutrition education strategies for sound food choice and regular meals need to be developed to improve the nutritional adequacy of female adults in the 20's.
This study investigated the correlations between nutrient intake and dietary attitudes in Korean school dietitians. A total of 493 school dietitians working in the Kangwon and Kyungnam areas participated in this study. The subjects were classified as the good group(33.5%), fair group(36.9%) and bad group(29.6%) based on dietary attitude score. The results were as follows. The average intake of energy, calcium, and iron were lower than the Korean RDA and average CPF ratio of energy intake was 64 : 17 : 19. The percent RDAs of nutrient intake of energy, calcium, iron and vitamin B$_1$were lower in the bad group than those in the fair group and good groups(p < 0.001). The mean adequacy ratio(MAR), an index of overall dietary quality, were different among the three groups(p < 0.001), the highest was 0.96 in the good group, the lowest was 0.88 in the bad group. The index of nutritional quality(INQ) was significantly higher in the good group than the other groups. The nutrient intakes were positively correlated with dietary attitudes(p < 0.01). The nutrient intakes, INQ, NAR and MAR were significantly increased as the dietary attitude score increased.
This study was conducted to investigate effects of nutrition education and exercise intervention on health and diet quality of middle-aged women. The subjects were 209 women who wanted to involve in the health promotion program run by Jincheon-Gun Health Center. Nutrition education was given once a week and dance sports were done twice a week for 3 months. Nutrient intakes were assessed by 24-hour recall method and food records. Dietary habits and nutrition knowledge were investigated by self-administered questionnaires before and after the intervention program. Body and blood compositions were measured before and after the program. The nutrient adequacy ratio (NAR) was significantly increased in energy, protein, vitamin A, vitamin B2 and calcium, mean adequacy ration (MAR) was significantly increased (p < 0.05), and also the index of nutritional quality (INQ) was significantly increased in protein (p < 0.01). Percent (%) RIs of protein (p < 0.01) and calcium (p < 0.05) were significantly increased and body weight (p < 0.001), body fat (p < 0.01), soft lean mass (p < 0.01) and BMI (p < 0.001) decreased. Over the 3-month study, there was a significant trend toward higher HDL-C and albumin levels and lower LDL-C level (p < 0.001). The results showed that nutrition education and exercise intervention could improve the body health and the diet quality.
This study was performed to evaluate served menu in Korean temples. Among available temples in the nation, 34 temples were carefully selected considering location and the gender characteristics. A five consecutive day menu was collected to analyse by interview between Jan 2004 and Aug 2004. Mean energy content of menu was 1633.8 kcal, with 67.3% of energy supplied by carbohydrate, 14.8% by protein and 17.9% by fat. Beans and bean products were the major contributing dishes for most nutrients. Contents of most nutrients except energy, protein and vitamin B were higher than RDA. Nutrient adequacy ratio (NAR) were 0.9-1.0 and mean adequacy ratio (MAR) was 0.9 for temples. Total number of dishes from menu was 7.3. Dietary variety score (DVS) was 26.4 and buddhist monk temples offered more diverse foods than buddhist nun temples. KDQI (Korean diet Quality Index), overall diet quality index were 0.67 and those of buddhist nun temples were better than those of buddhist monk temples. From the result of this study it was concluded that the temple diet is nutritionally well balanced, rich in dietary fiber and low in cholesterol. So it can be a healthy diet for the modern person. This is the very first study attempting the nationwide investigation of temple diet in Korea. It will be used as fundamental data to improve quality of diet to prevent modern chronic disease.
The objectives of this study were to identify dietary patterns of Korean middle school students and to investigate the characteristics of dietary intake of subjects with different dietary pattern. Three-day diet records were obtained from 163 male and 155 female 7th graders in Seoul, Korea. Food items from the diet records were aggregated into 22 food groups before subjected to factor analysis. Four dietary patterns emerged from factor analysis with different factor score. Cluster analysis using factor score classified subjects into three groups named 'Traditional' (n = 42), 'Westernized' (n = 135), and 'Intermediate' (n = 145). Major nutrient intake and dietary quality assessed by NAR (Nutrients Adequacy Ratio), MAR (Mean Adequacy Ratio), DDS (Dietary Diversity Score), and DVS (Dietary Variety Score) of the three groups were compared. Mean energy intakes of three groups were 1783, 1916, 1578 kcal in Traditional, Westernized, and Intermediate diet group respectively. Differences in nutrient intake of the groups were significant in all nutrients except vitamin B$_1$. Percent energy from fat was significantly higher in Westernized and Intermediate diet group, and cholesterol intake of Westernized diet group was higher than 300mg. NARs of most nutrients were higher in Traditional and Westernized than Intermediate diet group except vitamin E. Traditional and Westernized diet groups had the highest MAR of fourteen nutrients. DDS was the highest in Westernized and DVS was the highest in Traditional and Westernized diet group. Traditional diet groups had 22% of energy consumption from breakfast, significantly higher than other diet groups. In conclusion, these results suggest that Korean teenagers with Traditional diet pattern have lower diet in % energy from fat, diversity of food and regularity of meals. Future studies need to focus on the relationship between dietary patterns and health status of Korean teenagers.
This study was undertaken to identify dietary patterns of Korean elderly people living alone, and to compare the quality of diet consumed. Data of 821 elderly people aged 65 years or older who were living alone, was obtained from the 2016~2018 National Health and Nutrition Survey. The percentage energy intake from 24 food groups was calculated, and a cluster analysis was applied to identify dietary patterns. General characteristics, energy and nutrient intake, nutrient adequacy ratio (NAR), mean adequacy ratio (MAR), and index of nutritional quality (INQ) were analyzed. Dietary variety score (DVS) and dietary diversity score (DDS) were subsequently calculated. The rice-centered diet group and mixed diet group were characterized as consuming higher intake of rice and a wider variety of food groups, respectively. The mean age and percentage of participants living in rural areas were higher, whereas education level and monthly income were lower, in the rice-centered diet group (P<0.001 for all). Intakes of energy and all other nutrients (except carbohydrate and thiamine) were lower in the rice-centered diet group (P<0.001 for all). The NAR for all nutrients (except thiamine), MAR, and INQs (except thiamine and iron) were significantly lower in the rice-centered diet group (P<0.001 for all). The rice-centered diet group had significantly lower DVS (P<0.001) and DDS (P<0.001), as compared with the mixed diet group (P<0.001). Due to the insufficient energy and nutrient intake in the rice-centered diet group, it is necessary to develop nutritional monitoring and customized nutrition policies for these individuals.
This study was conducted to determine whether dietary factors could be related with serum adiponectin concentrations in 243, year-three female university students living in Seoul. The mean of body mass index (BMI) and adiponectin levels of all subjects were $20.17kg/m^2$ and $11.07{\mu}g/ml$, respectively. When the subjects were divided into 3 groups based on BMI (underweight: < 18.5, normal: $18.5{\leq}<23$, overweight and obesity: ${\geq}23$), serum adiponectin levels in underweight group was significantly higher than that in 'normal' or 'overweight and 'obesity' groups. Also when the subjects were divided into two groups by mean adequacy ratio (MAR), serum adiponectin concentration of the high MAR group (MAR > 75) was slightly higher than that the low MAR group ($MAR{\leq}75$). Serum adiponectin levels showed a negative correlation with body weight (p < 0.01) or BMI (p < 0.001) and a positive correlation with intakes of of animal or total protein (please clarify) or vegetable protein.Among the dietary behaviors, serum adiponectin levels of females who answered 'yes' to the question about 'eating breakfast' was significantly higher than that of those who answered 'sometimes' or 'No' (p < 0.05) and serum adiponectin levels were higher among those who reported higher fruit intakes. Overall, our results suggested that healthy lifestyle including acceptable BMI, eating breakfast and higher fruit consumption might play an important role in the prevention of obesity and enhancement of blood adiponectin levels.
To assess the nutrient intake and diet quality of Korean adults living in rural area, dietary survey with one day 24 -hour recall method was given to 2037 subjects over 30 years of age living in Yeoncho-gun, Kyungki province of Korea, together with health survey. The mean daily energy intake was 1583 kcal, with 65.4% of energy intake being supplied by carbohydrate, 15.9% by protein and 18.7% by fat. Eighty percents of total food intake were supplied by vegetable food and the rest in the form of animal food . As well as insufficiencies in calcium and iron intake, the bioabailability of calcium and iron is considered to have been low because most of those intakes came form plant origins. For most nutrients except phosporous, proportions of subjects with intake levels less than 75% of RDA was over 40% and highest in the elderly. Those proportion of low intake among female were higher than those among male. The mean adequacy ration(MAR) , an index of overall dietary quality was 0.62 for females and 0.68 for males and decreased with increase of age. The indexes of nutritional quality (INQ) were over 1 for most nutrients except 0.06 of vitamin A, 0.73 of calcium and 0.85 of vitamin C, Nutrient intake levels less than 75% of RDA may be appropriate as a criteria for insufficiency of nutrient intake. Based on these results, it is evident that some of adults in rural areas did not consume enough nutrients, especially vitamin A, calcium and vitamin B$_2$, and that the dietary intake of female and the elderly was not adequate .
To assess the quality of nutrient intake by area of Korean adults, a dietary survey with the 3-day record method was obtained from 324 subjects aged 40 years and older but younger than 70 (52.4 $\pm$ 8.7) living in a rural area (Ansung) and suburban area of a middle-sized city (Ansan). The quality of nutrient intake was assessed by analyzing Nutrient Adequacy Ratio (NAR), Mean Adequacy Ratio (MAR) and Index of Nutritional Quality (INQ). The average daily mean energy intakes were 1,832 ㎉ for Ansung and 1,842 ㎉ for Ansan, respectively. Daily intakes of fat for Ansung and Ansan subjects were 40.9 and 40.3 g, and those for protein were 75.1 and 73.1 g, respectively. The overall calorie: protein: fat ratio (CPF) of energy intake was 63 : 17 : 20. Daily mean intakes of protein, fat, calcium, phosphorus, iron, potassium, carotene, sodium, thiamin, and niacin were significantly higher in Ansung residents than in Ansan subjects (p < .05). The average intakes of energy, calcium, vitamin A were lower than Recommend Dietary Allowance (RDA) in both areas. Note, over 30% of the study subjects had less than 75% of RDA of calcium, vitamin A and riboflavin. The MAR was higher in Ansung than Ansan residents (0.86 and 0.85, respectively; p < .05). INQs were over 1 for most nutrients except calcium (0.87), and that of calcium and phosphorus was each significantly higher in Ansung than Ansan subjects. Based on these results, nutrient intake quality of subjects aged 40 to 69 years living in the surveyed rural area is comparable to that of semi-industrialized suburban area in Korea. Dietary deficiency in all of calcium, vitamin A, and riboflavin, however, was a common problem for both rural and suburban residents.
