The purpose of this study was to evaluate the relationship between the diversity of food intake and nutrient intake among Korean college students participating in a nutrition education class via the internet. The subjects were 796 college students throughout South Korea (278 males, 518 females). A 3 days dietary recall survey was conducted and results were analyzed using the Computer-aided Nutritional Analysis Program. Dietary variety was assessed by DDS (dietary diversity score), MBS (meal balance score), and DVS (dietary variety score). Dietary quality was assessed by NAR (nutrient adequacy ratio), and MAR (mean adequacy ratio). As the DDS, MBS and DVS increased, the NAR and MAR improved. The subjects with a DDS of above 4 or a MBS of above 10 or a DVS of above 11 met two-thirds of the Korean recommended dietary allowance for most nutrients. The DDS, MBS and DVS correlated positively and significantly with the NAR and MAR. Associations between the NAR and high levels of DVS were more positive than those between the NAR and the DDS. Based on these results, the food intake of these subjects was not adequate. Specially, the dietary intake of calcium and iron were not adequate. Therefore, dietary guidelines should be made considering nutritional characteristics so as to improve the intake from all of the major food groups and provide a variety of foods in their diets.

This study was performed to assess the extent of dietary diversity and nutrient intakes of Korean child-bearing women and to investigate the relationships between dietary diversity indices and nutrient intakes. A total of 91 women aged 18 to 48 years old participated. They were divided into four groups by age 15 subjects in teens, 20 in twenties. 32 in thirties and 24 in forties. Mean energy intake was 1638${\pm}$471㎉/day and it was low as 81.4% of the Korean RDA for energy. Mean intakes of folate, calcium and iron were also low as 81.7%. 72.6% and 57.2% of the RDAs. On the other hand, protein, vitamin A, thiamin, riboflavin and vitamin C were consumed close to or above the RDAs. It was obvious that the subjects in teens and twenties took less all of the nutrients as well as energy than those In thirties and forties. Mean nutrient adequacy ratio( MNAR) was 0.77 and showed a trend to raise with increasing age. Thus MNAR of the teens was the lowest and that of the forties was the highest among the age groups. The results in this study support the previous findings that nutrient intakes of women in teens and twenties were poorer compared to those in thirties and forties. Mean dietary diversity score( DDS) . dietary variety score(DVS) and dietary frequency score( DFS) were 4.1. 11.6 and 14.7. respectively. DVS and DFS of the teens and twenties were lower than those in thirties and forties. DDS significantly correlated to the intakes of energy and calcium only, however, DVS and DFS had significant relationships to the intakes of all nutrients. The MNAR significantly related to DVS and DFS. but not DDS. In conclusion, the intakes of energy, folate. calcium and iron of child-bearing women were not sufficient and their nutrient adequacy highly correlated with dietary diversity. It indicates that to consume various foods helps to enhance the nutritional status.

This study was intended to investigate the relation between nutrient status and food diversity of elementary school students in Daegu-Kyungpook area. The subjects were 164 elementary school students (82 boys, 82 girls) who participated in "Dietary Intake Survey of Infants, Children and Adolescents" conducted by Korea Food & Drug Administration and Korea Health Industry Development Institute. We analyzed the nutritional status for two non-consecutive days by 24 hour recall method. Adequacy of dietary intake was evaluated by the proportion of subjects consuming nutrients less than Estimated Average Requirements (EAR). Food diversity was compared by using Dietary Diversity Score (DDS) and Dietary Variety Score (DVS). Nutrients intake was significantly higher in boys than girls. Subjects who consumed all food groups showed higher intake of energy and other nutrients. Boys maintained better diet quality than girls, measured by Dietary Diversity Score (DDS) as well as Dietary Variety Score (DVS). Based on these results, nutrition education for elementary school students should focus on the importance of consuming all food groups with more attention for girls.

The purpose of this study was to evaluate nutrient intake and anthropometric parameters related to obesity in Korean female adolescents according to dietary diversity score. We analyzed data from the combined 2007-2009 Korean National Health and Nutrition Examination Survey (KNHANES). The subjects were 770 female adolescents. Nutrient intakes, Dietary Diversity Score (DDS) ) and Dietary Variety Score (DVS) were derived by using the data from the 24-recall method. The DDS was defined as the number of six food groups (cereals, meats, fruits, vegetables, dairy, fats and oils) consumed. The DVS was defined as the number of food items consumed. The average age of the subjects of the study was 15.02 years and the average height, weight, and BMI were 159.50 cm, 52.58 kg, 20.62 kg/$m^2$, respectively. The energy and nutrients intakes, percent of the recommended intake for nutrients in DDS = 5~6 group were significantly higher than those of the other groups. Calcium and vitamin C INQ in DDS = 5~6 group were significantly higher than those of the other groups. The average DVS of the subjects was 29.33. The most frequent style of food pattern was CMDFVO (cereals, meats, dairy, fruits, vegetables, fats and oils) = 111011. In conclusion, in healthy Korean female adolescents, food diversity intake variety did beneficially affect the intakes of calcium and vitamin C. Further studies are needed to confirm these findings.

This study was performed to evaluate effects of dietary variety scores (DVS) and dietary diversity scores (DDS) on the nutritional quality of the diets of Korean college students, and to examine the association between food group intake patterns and nutritional adequacy. This study examined the relationship of dietary diversity scores (DDS), dietary variety scores (DVS), and food group intake patterns with nutrient intakes using 24-hour recall data (n=.358). The .DDS was calculated from the sum of each of the five food groups consumed as a score of 'I'. DVS was determined by counting the number of food items consumed daily. Food group intake patterns were expressed with the presence or omission of five major food groups-dairy, meat, grain, fruit, and vegetable. The four most prevalent food group patterns and the proportion of the population reporting them were as follows; no dairy and fruit, $23\%;\;no\;dairy,\;20\%;$ no dairy, meat, and fruit, $15\%$; all food groups, $14\%$. Even though the DDS or DVS was higher, the majority of this study population failed to meet the Korean RDA for calcium in both genders and iron in women. Higher DVS scores $(\geq31)$, within all DDS groups, were associated with the largest proportion of individuals consuming more than $75\%$ of the Korean RDA for selected nutrients. The consistency of these results indicates that screening diets to evaluate the overall dietary variety and variety among the major food groups including food group intake patterns provide meaningful information about their quality.

Despite the universal recommendation to eat a variety of foods, we still do not know whether and to what extent the variety affects dietary quality. This study was performed to evaluate the dietary variety scores as tools for assessing the dietary quality of Korean young adults. The 1-day dietary intake data were collected from 144 male and 214 female college students (>18 years) using the 24-hour recall method Relative nutrient intake compared to Korean Recommended Dietary Allowance (KRDA) as the nutrient adequacy ratio (NAR), were computed Also, the mean adequacy ratio (MAR) was calculated. Dietary variety score (DVS) was determined by counting the number of food items consumed daily, and the dietary diversity score (DDS) by counting the number of food groups consumed daily. Results showed that DVS, DDS and MAR were significantly correlated to each other. The MAR score significantly increased as DDS increased in both men and women. When different DVS (20$\leqDVS\leq$ 30) was evaluated for its sensitivity, specificity, measured prevalence, true prevalence, and positive and negative predictive values towards MAR, DVS 21 was revealed to be optimal dietary variety score as a cutoff point to differentiate Korean young adults with or without an adequate and balanced diet. Nutrient intakes of subjects who had DVS<21 were significantly lower than those of subjects with DVS$\qeq$ 21. These results indicate that the dietary variety score appeared to be an effective tool for evaluating the adequacy of diet in Korean young adults.

To assess the food intake and diet quality of preschool children in Pusan, dietary survey was conducted with 176 subjects using 24hr recall method. Diet quality was assessed by food group pattern, dietary diversity score(DDS), dietary variety score(DVS), and dietary frequency score(DFS). The total number of food items consumed was 307. The foods consumed most frequently were rice, Korean cabbage kimchi, milk and green onion. When investigating the consumption pattern of major six food groups, 38.1% of subjects consumed all six groups. Food group was missed in order of fruit(41.5%), sweet(19.9%), dairy(16.5), vegetable(4.5%) and meat(1.7%). The mean values of DDS, DVS, and DFS were 5.16, 13.82, and 16.07 re spectively. Persons who had higher DDSs also had higher DVSs(p<0.001). DDS, DVS and DFS correlated positively with NAR(nutrient adequacy ratio) and MAR(mean adequacy ratio) significantly. Associations between the NAR of most nutrients and MAR with DVS and DFS were higher than those between the NAR of most nutrients and MAR with DDS. People with DDS of above 6 or DVS of above 16 or DFS of above 21 met two thirds of recommended dietary allowance for nutrients. Based on the result of the food group intake, the food intake of subjects was not adequate, especially the fruit and dairy groups. When assessing the dietary quality of subjects using DDS, DVS and DFS, many people appeared not to have a desirable food intake.

To assess the food intake and diet quality of Korean adults living in rural areas , a dietary survey using a one day 24-hour recall method was conducted with 2037 subjects over 30 years of age living in Yeonchon-gun , Kyungki province of Korea. Eighty percent of total food intake was in the form of vegetable food and the rest in the form o fanimal food . Diet quality was assessed by food group pattern, dietary diversity score(DDS), and dietary variety score(DVS). When counting the major food groups consumed (DDs), 47% of subjects had a DDS of 3 and 31% of subjects had a DDs of 4. On average, subjects habitually consumed 14.9 different foods daily, with the mean score of diet variety (DVS) for males(14.4) being significantly lower than for females (15.2). Persons who had higher DDSS also had higher DVSS(p<0.001). As the DDs increased , MAR(Mean adequacy ratio) improved. Correlation coefficients between NAR(nutrient adequacy ratio) and DVS ranged from r=0.34 for vitamin C to re=0.51 for vitamin B$_2$. NAR also improved as the number of foods or food groups consumed increased (p<0.001). Associations between the NAR of most nutrients with DVS was better than those with DDS. Based on these results, the food intake of the study subjects was not adequate, especially with regards to the dairy and fruit groups . Dietary diversity (DDS) and especially dietary variety (DVS) would be useful in assess nutrient intake because of their associations with total diet quality.

This study attempted to estimate the dietary quality and the food diversity by analyzing the military foodservice menu. To evaluate the dietary quality, an analysis of NAR(Nutrient Adequacy Ratio) and MAR(Mean Adequacy Ratio) were carried out. DDS(Dietary Diversity Score), DVS(Dietary Variety Score) and DMGFV(Dairy Product, Meat, Grain, Fruit, Vegetable group) were used for assessment of food diversity. A Can-pro 3.0 and an excel were used for dietary data analysis and SPSS 12.0 program was used for statistical analysis. The results were as follows. The NAR of the 9 nutrients was above the RDAs and MAR was $1.71{\pm}0.19$. For 19 days(61.3%), DDS was 5 and for 12 days(38.7%), DDS was 4. The average of DDS was $4.6{\pm}0.25$. The Fruit & vegetable groups were not often served compared to other groups and especially fresh fruit were not given enough. The average of DVS and DVSS were $22.48{\pm}0.61$ and $29.26{\pm}0.66$ each. The most frequent food pattern was 'DMGFV=11111' which was served for 19 days(61.3%) and second frequent pattern 'DMGFV=11101' was served for 12 days(38.7%). DDS was significantly associated with Vit. C intake and DVS and DVSS was significantly related to Vit. $B_1$ and Vit. $B_2$ intakes. The MAR was significantly correlated with only DVSS. It could be interpreted that DVSS is a useful parameter for evaluating nutrient intakes as previous studies verified. Based on these findings, it can be said that military foodservice was provided with adequate nutrition and diversity. Menu was well composed of various foods which met the nutrition standards, but should provide more fresh fruits for adequate provision of vitamins and minerals.

The purpose of this study was to evaluate the diversity of food intake among Korean college students of a nutrition education course through the internet. Subjects were 796 nation-wide college students (male 278, female 518). A dietary survey collected from 3 day-recalls were analyzed by the Computer Aided Nutritional Analysis Program. Diet variety was assessed by DDS (dietary diversity score), MBS (meal balance score), and DVS (dietary variety score). The foods consumed in largest amounts were rice (54.42 g), citrus fruit (36.41 g) and milk (30.91 g). The foods consumed most frequently were rice (65.28%), garlic (63.65%) and salt (63.64%). The average food intake was 1325.3 g (male 1420.6 g, female 1274.1 g), with vegetable and animal food comprising 78.5% and 21.5% of total food intake, respectively. The consumption of the major five food groups comprised DDS, and 66.0% (male 56.1%, female 71.3%) of subjects had a DDS of 5 and 27.4% (male 33.5%, female 24.1%) of subjects had a DDS of 4..Groups most frequently missed were dairy products (56.5%) and fruits (41.6%). The average of MBS were 10.88 (11.61 in Seoul, 11.03 in Kyungsang, 10.88 in Chungcheong, 10.85 in Incheon, 10.57 in Kyunggi) in male and 11.08 (11.47 in Kyungsang, 11.20 in Seoul, 11.18 in Kyunggi, 10.82 in Chungcheong, 10.64 in Incheon) in female. Male students in Seoul (18.2) and female students in Kyungsang (18.6) had the greater number of consumed food items. Subjects who had higher DDS had significantly higher DVS (p < 0.001). Based on these results, the food intake of the subjects regarded as not adequate, especially with regards to the dairy and fruit groups. Considering their nutritional characteristics, dietary guidelines as well as education should be made to improve the food intake and include various foods in their diet.
