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.

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 diet quality by food group intake and to investigate the interrelationship of age, dietary diversity score(DDS), dietary variety score(DVS), dietary frequency score(DFS), food group intake and nutrient intake with food group intake, a dietary survey was conducted with 176 preschool children aged 1 to 6 in Busan using a 24-hr recall method. Food group intake was assessed by food number consumed and intake frequency by six food groups(grain, meat, vegetable, fruit, dairy, sweets group). The mean food numbers consumed and intake frequencies by six feed group were 3.1 and 4.0 in the grain group, 3.6 and 4.0 in the meat group, 3.5 and 4.1 in the vegetable group, 1.0 and 1.1 in the fruit group, 1.3 and 1.5 in the dairy group, 1.4 and 1.4 in the sweets group respectively. As age increased, the intake frequency of the grain group(p<0.05) increased but that of the dairy group(p<0.05) decreased significantly. The DVS and DFS didn't show significant correlations with intake frequency of the dairy group. The grain group intake had significant positive correlations with intakes of the meat, vegetable, and fruit groups. The vegetable group intake had signigicant positive correlations with intakes of the grain and meat groups. The dairy group intake had significant positive correlation with sweets group intake but negative correlations with intakes of the grain and vegetable groups. As the intake frequency of the meat group increased, the NAR(nutrient adequacy ratios) of all nutrients and NAR(mean adequacy ratio) increased significantly. NARs of provein iron, vitamin B$_1$, niacin had the highest correlation with the meat group intake and those of protein, calcium, phosphorous, and vitamin B$_2$ had the highest correlation with the dairy group intake. NARs of vitamin A and vitamin C had the highest correlation with intake of the vegetable and fruit groups respectively. Children with food number consumed and intake frequency of above 6 and 4 in the grain group or above 6 and 6 in the meat group or above 4 and 8 on the
